As inventory control of pharmaceutical products, a method of replenishing a quantity sold (used) is common, and Patent Document 2 shows a technique premised on this method.

JP-A-2002-251456 Japanese Unexamined Patent Publication No. 2003-44591

Since the general inventory management method replenishes only the quantity sold, the quantity of inventory set as a target is constant. In addition, the quantity of inventory that has been set is merely set by a person as appropriate. If the inventory margin set at the beginning is increased, many medicines will expire, and if the inventory margin is reduced, shortages are likely to occur.

The present invention has been made in view of such a situation, and an object of the present invention is to provide an inventory control method for a drug, which is unlikely to cause an expiration date or a shortage.

The drug inventory management system of the present invention is connected to a pharmacy terminal, which is a terminal installed in a pharmacy, via a network. The drug inventory management system of the present invention has a recording means having a drug common information recording unit, a drug individual information recording unit, and a prescription information recording unit, a prescription information acquisition means, a set stock quantity calculation means, an inventory information update means, and an inventory status determination means. To be equipped. The drug common information recording unit records drug IDs and attribute information, which are information for identifying drugs, for each drug. The individual drug information recording unit records inventory information including repeat parameters, sales quantity information, set lower limit inventory quantity, and quantity information for each expiration date for each pharmacy and each drug. The prescription information recording unit includes a pharmacy ID which is information for identifying the received pharmacy, a patient ID which is information for identifying the patient, date information which is information including the issue date of the prescription, and information on the quantity and the number of days for each drug. Record prescription information. Attribute information is information indicating whether or not a drug has addiction or timing. The repeat parameter is a parameter that is set when the attribute information is addictive, and is a parameter that indicates the rate at which the same patient purchases the same drug again for each pharmacy and each drug. The number of sales information is information showing the average number of sales for each pharmacy and each drug when the attribute information is non-timely, and when there is timely, the annual change for each pharmacy and each drug is displayed. This is information indicating the number of sales included. The prescription information acquisition means acquires prescription information for each prescription and records it in the prescription information recording unit. The set inventory quantity calculation means calculates the set inventory lower limit number, which is the lower limit of the inventory quantity to be set, for each pharmacy and each drug by using the prescription information, the attribute information, the repeat parameter, and the sales quantity information. More specifically, the set inventory quantity calculation means obtains the set inventory lower limit using the prescription information, the repeat parameter, and the sales quantity information in the case of a drug with addiction, and the sales quantity in the case of a drug without addiction. Use the information to find the set lower limit of inventory. The inventory information updating means updates the inventory information recorded by the recording means for each pharmacy and each drug. The inventory status determination means compares the number of inventories with the set lower limit of inventory for each pharmacy and each drug, and if the number of inventories is less than the set lower limit of inventory, a predetermined process is performed.

According to the drug inventory management system of the present invention, drugs are distinguished by the attributes of addiction or non-addiction, and the lower limit of the number of drugs that should be kept in stock in consideration of the repeat parameter and the annual change in the number of sales. Ask for. Therefore, it is less likely that the expiration date will be exceeded or the product will be out of stock, as compared with the case where a person sets the quantity of inventory as appropriate.

Hereinafter, embodiments of the present invention will be described in detail. The components having the same function are given the same number, and duplicate description is omitted.

FIG. 1 shows an example of the functional configuration of the drug inventory management system. The drug inventory management system 100 includes at least a recording unit 190, a prescription information acquisition unit 120, a set inventory quantity calculation unit 110, an inventory information update unit 130, and an inventory status determination unit 140, and further includes an adjustment information acquisition unit 125 and a parameter learning unit 150. , Parameter updating means 200 and parameter initial setting means 300 may also be provided. Each means may be arranged in different devices (computers) connected by a network, or may be arranged in one device. When each means is arranged in a different computer, there will be a program for each means, for example, a program for operating the computer as the set inventory number calculation means 110. Further, when all the means are arranged in one device (when the drug inventory management system is configured in one device), the drug inventory management device 101 is used. The drug inventory management system 100 is connected to at least the pharmacy terminals 400 ₁ , ..., 400 _N , which are terminals installed in the pharmacy, via the network 900. The drug inventory management system 100 may also be connected to wholesale terminals 500 ₁ , ..., 500 _N , which are terminals or devices installed in the drug wholesale company, via the network 900. N and M are integers greater than or equal to 1.

FIG. 2 shows a configuration example of the recording means 190. The recording means 190 has at least a drug common information recording unit 191, a drug individual information recording unit 192, and a prescription information recording unit 193. Further, the recording means 190 may also include a transferable information recording unit 194. FIG. 3 is a diagram showing an example of a processing flow for inventory management of a drug inventory management system, FIG. 4 is a diagram showing an example of a processing flow for updating parameters of a drug inventory management system, and FIG. 5 is a process flow for initial setting of parameters of a drug inventory management system. It is a figure which shows an example.

The drug common information recording unit 191 is a recording unit that records information on drugs common to all pharmacies, and records at least drug IDs and attribute information that are information for identifying drugs for each drug. Attribute information is information indicating whether or not a drug has addiction or timing. Addiction is a property that indicates addictive use such as drugs for diabetes and hypertension and anticancer drugs. Seasonality is a property that indicates that the number of products sold (prescribed quantity) such as medicines for hay fever, colds, and influenza depends on the time (season). For example, hay fever medicines are addictive and timely medicines, diabetes medicines are addictive but not timely medicines, cold medicines are not addictive but timely medicines, and wound medicines are addictive. Drugs are classified into four types according to attribute information, such as drugs that have neither sex nor timing. The drug common information recording unit 191 further includes delivery date information indicating the delivery date, an ordering unit which is a unit of the number of items when purchasing from a drug wholesaler, a transfer unit which is a unit of the number of items when transferring a drug between pharmacies, and a drug. It suffices to record the expiration date information including the information on the period from the time of manufacture to the expiration date, and the adjustment information which is the information on the change in the number of sales. The delivery date information may be recorded in the drug individual information recording unit 192, which will be described later. Also, the transfer unit is a smaller number than the ordering unit.

The individual drug information recording unit 192 is a recording unit that records information for each pharmacy and for each drug, and is at least information that identifies the pharmacy, such as a pharmacy ID, a drug ID, repeat parameters, sales quantity information, and a set lower limit inventory number. Record inventory information, including quantity information for each expiration date. The repeat parameter is a parameter set when the attribute information is addictive, and is a parameter indicating the rate at which the same patient purchases the same drug again for each pharmacy and each drug. The number of sales information is information showing the average number of sales for each pharmacy and each drug when the attribute information is non-timely, and when there is timely, the annual change for each pharmacy and each drug is displayed. This is information indicating the number of sales included. The "average number of sales" may be, for example, the average number of sales for a predetermined period (for example, one day, one week, one month) obtained from the total number of sales in a year. The "number of sales including annual changes" may be, for example, the number of sales divided into predetermined periods (for example, daily, weekly, monthly), or average sales. It may be information on the ratio (timing parameter) of the number of sales to the number and the average number of sales when divided by a predetermined period. The drug individual information recording unit 192 may also record the wholesale ID, which is the identification information for identifying the drug wholesale company of the drug, and the set upper limit of inventory. The upper limit of the set inventory is a number that is one less than the order unit and larger than the lower limit of the set inventory. That is, the set inventory upper limit is a number that is one less than the set inventory lower limit and does not exceed the inventory when the inventory is increased by the order unit.

The prescription information recording unit 193 is information including at least the pharmacy ID of the pharmacy received, the patient ID which is the information for identifying the patient, and the issue date of the prescription from the pharmacy terminal 400 _n (where n is an integer of 1 or more and N or less). Record prescription information, including date information, quantity and number of days for each drug. The prescription information acquisition means 120 acquires prescription information for each prescription and records it in the prescription information recording unit 193 (S120). The prescription information may also include a hospital ID, which is information identifying the hospital that issued the prescription, and the gender and age of the patient. The patient ID does not have to be information that can identify an individual such as the patient's name, and may be information that can determine whether or not the patient is the same when comparing prescription information. Information such as numbers and symbols may be used.

When the adjustment information acquisition means 125 is also provided, the adjustment information acquisition means 125 acquires the adjustment information when there is the adjustment information which is the information regarding the change in the number of sales (S125). The adjusted information is, for example, information indicating that the influenza epidemic has started earlier than usual.

The set inventory quantity calculation means 110 calculates the set inventory lower limit number, which is the lower limit of the inventory quantity to be set, for each pharmacy and each drug, using at least prescription information, attribute information, repeat parameters, and sales quantity information (S110). .. In the case of a addictive drug, the set inventory quantity calculation means 110 obtains the set inventory quantity lower limit number by using the prescription information, the repeat parameter, and the sales quantity information. In the case of non-addictive drugs, the set lower limit of inventory is calculated using the sales quantity information. For example, the repeat parameter is the rate of the same patient purchasing the same drug again at each pharmacy (for example, if 8 out of 10 patients purchase the same drug again, the repeat parameter is 0.8). In this case, the calculation may be performed as "set lower limit number = average number of sales per month x α + repeat parameter x number of medicines shown in the target prescription information". In the case of addiction, "average number of sales per month x α" corresponds to the margin, and the value of α may be determined for each pharmacy and each drug in consideration of the delivery date of the drug. If there is no addiction, it may be calculated as "lower limit of setting = average number of sales per month x α", or if the repeat parameter = 0 using the same formula as when there is addiction. Good. The value of α will be larger in the case without addiction than in the case with addiction. When the prescription information includes a plurality of addictive drugs, the set stock quantity calculation means 110 repurchases all the repeat parameters of the plurality of addictive drugs among the repeat parameters. The set lower limit number of stocks may be obtained by setting the repeat parameter indicating that the ratio is the highest. For example, the more serious the illness, the higher the rate of repurchasing. Then, when purchasing a drug with a high rate of repurchasing, a drug for a mild illness is also purchased, so it is more accurate to calculate the required inventory quantity in this way.

For example, it is assumed that drug A and drug B are addictive and have no addiction, drug C is addictive and timely, and drug D is not addictive. In the following example, the rate of the same patient purchasing the same drug again at each pharmacy is used as the repeat parameter. For example, it is 0.8 when 8 out of 10 people purchase the same drug again. As described above, the repeat parameter need not be limited to this example because it is sufficient to indicate the ratio of the same patient purchasing the same drug again at each pharmacy. For example, the percentage of patients who do not repurchase may be used, and the repeat parameter is 0.2 when 8 out of 10 patients repurchase the same drug.

<Example 1>
When 60 prescriptions of drug A for 30 days are received from the first patient X and the repeat parameter of drug A is 0.8, the prescription information acquisition means 120 acquires prescription information. The set inventory quantity calculation means 110 increases the set inventory lower limit number of the received drug A of the pharmacy by 48 (= 60 × 0.8), and indicates that the prescription information is used for calculating the set inventory lower limit number. Record information. Then, if patient X comes to purchase with the prescription for which the drug A is prescribed again within 30 days from the prescription issuance date, the set lower limit of inventory is not changed for the same quantity of prescriptions. When the prescribed quantity changes, the set lower limit of inventory is changed by the amount of change × repeat parameter. In addition, the information indicating that the old prescription information is used in the calculation of the lower limit of inventory is deleted, and the information indicating that the new prescription information is used in the calculation of the lower limit of inventory is recorded. If patient X does not arrive within 30 days after the prescription issuance date, the set lower limit of inventory of drug A at the accepted pharmacy is reduced by 48, indicating that the prescription information is used to calculate the lower limit of set inventory. Delete the information. After that, when patient X comes again, it may be treated as the first patient. In this example, the revision of the set lower limit of inventory is calculated from the prescription issuance date, but if the date information of the prescription information also has the information of the date received by the pharmacy, the start date is the date received by the pharmacy. It doesn't matter.

<Example 2>
From the first patient X, we accepted prescriptions showing 30 medicines A for 15 days and 15 medicines B for 15 days, and the repeat parameter of medicine A was 0.8 and the repeat parameter of medicine B was 0. In the case of 9, the set stock quantity calculation means 110 also calculates the repeat parameter of the drug A with 0.9. That is, the set lower limit of inventory of drug A of the accepted pharmacy is increased by 27 (= 30 x 0.9), the lower limit of set inventory of drug B is increased by 13.5 (= 15 x 0.9), and the prescription is increased. Record information indicating that the information is being used to calculate the set stock limit. Then, if patient X comes to purchase with the same prescription in which the drug A and the drug B are prescribed again within 15 days after the prescription issuance date, the set lower limit of inventory is not changed. If patient X does not arrive within 15 days after the prescription issuance date, the lower limit of the set inventory of drug A of the accepted pharmacy is reduced by 27, the lower limit of set inventory of drug B is reduced by 13.5, and the prescription information is set. Delete the information indicating that it is used in the calculation of the lower limit of stock.

<Example 3>
Received a prescription from patient X indicating 30 medicines C for 30 days, the repeat parameter of medicine C was 0.6 (the ratio of 6 out of 10 people purchasing the same medicine again), and the number of sales. From the information, the case where the ratio of the number of sales after 30 days to the number of sales on the prescription issuance date is 0.9 will be described. If there is no prescription information for the same drug at the same pharmacy of patient X in one year, the set inventory number calculation means 110 sets the lower limit of the set inventory of drug C of the received pharmacy to 16.2 (= 30 × 0.6 ×). 0.9) Increase and record information indicating that the prescription information is used to calculate the set lower limit of inventory. Then, when patient X comes to purchase the drug C again with the prescribed prescription within 30 days after the prescription issuance date, the set lower limit of inventory is changed according to the ratio between the prescribed number and the number of sales. In addition, the information indicating that the old prescription information is used in the calculation of the lower limit of inventory is deleted, and the information indicating that the new prescription information is used in the calculation of the lower limit of inventory is recorded. If patient X does not arrive within 30 days after the prescription issuance date, the set lower limit of inventory of drug C of the accepted pharmacy is reduced by 16.2, and the prescription information is used to calculate the set lower limit of inventory. Delete the information that indicates. In the case of pharmaceutical product C, there is a possibility that it is only temporarily unnecessary due to the timing, so the set inventory quantity calculation means 110 sets the set inventory lower limit number to the number of sales indicated by the sales quantity information. Make sure that the quantity does not become less than the quantity including the predetermined margin (the minimum value of the set lower limit of inventory is changed in conjunction with the sales quantity information). In addition, since it is considered that the information that patient X purchased the same drug at the same pharmacy one year ago (at the same time last year) is included in the sales number information of this year at that pharmacy, the set inventory quantity calculation means 110. If there is prescription information for the same drug at the same pharmacy in Patient X for one year, but there is no information to indicate that the (their) prescription information is used to calculate the lower limit of the set inventory, then the set inventory The lower limit number may not be changed.

<Example 4>
In the case of the drug D, the quantity including the predetermined margin in the number of sales indicated by the number of sales information may be set as the set lower limit of inventory. If the drug D is timely, for example, the set lower limit of inventory may be obtained from the sales number information after the number of days considering the delivery date for each drug, or for all the timely drugs in advance. The set lower limit of inventory may be obtained by using the sales quantity information after a predetermined number of days.

Further, when the adjustment information acquisition means 125 acquires the adjustment information, the set inventory quantity calculation means 110 obtains the set inventory lower limit number by using the adjustment information as well. For example, it is assumed that an influenza epidemic usually starts around November 20th, but the possibility of an epidemic increases from around November 5th. In this case, the adjustment information acquisition means 125 acquires information indicating that the demand for the drug for influenza is 15 days earlier than usual as the adjustment information. The set inventory quantity calculation means 110 may obtain, for example, the set inventory lower limit number of the drug for influenza by using the sales quantity information after the number of days obtained by adding 15 days to the number of days considering the delivery date.

Further, the set inventory quantity calculation means 110 may also obtain the set inventory upper limit number. The set inventory upper limit number S _MAX may be calculated by a predetermined method so that the number is larger than the set inventory lower limit number S _MIN by one or more less than the ordering unit U. In other words
S _MAX ≧ S _MIN + U-1
It may be obtained setting stock upper limit the number of S _MAX in such a way that. In this case, the drug individual information recording unit 192 also records the set upper limit of inventory.

The inventory information updating means 130 updates the inventory information recorded by the drug individual information recording unit 192 of the recording means 190 for each pharmacy and each drug (S130). For example, the inventory information updating means 130 may reduce the quantity of inventory having a short period until the expiration date according to the acquired prescription information. Alternatively, the inventory information updating means 130 may acquire the drug ID and the quantity information for each expiration date as sales information separately from the prescription information from the pharmacy terminal 400 _n , and update the inventory information. The latter can more accurately grasp the inventory status, but the processing at the pharmacy becomes complicated.

The inventory status determining means 140 compares the inventory quantity and the set inventory lower limit number for each pharmacy and each drug, and when the inventory quantity is less than the set inventory lower limit number, performs a predetermined process (S140). There can be various processes as the "predetermined process". For example, information on a drug whose inventory is low is transmitted to a pharmacy terminal 400 _n installed in a pharmacy whose inventory quantity is less than the set lower limit inventory quantity. When the wholesale ID is recorded in the drug individual information recording unit 192, and when an order is instructed from the pharmacy terminal 400 _{n, the} wholesale terminal installed in the drug wholesale company identified by the wholesale ID. The process of ordering medicines in the quantity of the ordering unit may be included in 500 _m (where m is an integer of 1 or more and M or less). Alternatively, it may be a process of ordering medicines in the quantity of the ordering unit from the wholesale terminal 500 _m automatically identified by the wholesale ID and notifying the pharmacy terminal 400 _n that the order has been completed.

When the set inventory upper limit number is recorded in the drug individual information recording unit 192, the inventory status determination means 140 also compares the inventory quantity with the set inventory upper limit number. In this case, when N is 2 or more, it is desirable that the recording means 190 also includes the transferable information recording unit 194. Then, when the inventory quantity is larger than the set inventory upper limit number, the inventory status determination means 140 can transfer the drug ID, the pharmacy ID, the transferable number information which is information indicating the transferable quantity, and the expiration date as transferable information. Record in the information recording unit 194. The transferable number information may be the quantity itself or information indicating the number of units to be transferred. In this case, the variation of the above-mentioned "predetermined processing" increases. For example, the inventory status determination means 140 first confirms whether the transferable information recorded by the transferable information recording unit 194 includes information on a drug whose inventory quantity is less than the set inventory lower limit number. If not, the process proceeds to the above-mentioned order processing. In some cases, there may be more various steps to be taken. For example, availability determination unit 140 notifies the transferable information and that there are drugs that can be transferred between pharmacy pharmacy terminal 400 _n. At the pharmacy, after confirming the expiration date and the like, it is sufficient to transmit from the pharmacy terminal 400 _n that the transfer is desired. In the stock status determination means 140, the pharmacy terminal 400 _n is installed at the pharmacy terminal 400 _k (where k is an integer of 1 or more and N or less and k ≠ n) identified by the pharmacy ID included in the transferable information. Identify the pharmacy and notify them to transfer the drug. This example is a process on the premise that the transfer is carried out under the responsibility of the pharmacies, but since it is possible that a third party may intervene in the transfer business, the "predetermined process" part is the form of business. It may be appropriately designed according to the needs of the pharmacy and the pharmacy.

When the drug inventory management system 100 further includes the parameter learning means 150, the following processing is performed. The inventory status determination means 140 confirms whether or not there is an inventory of medicines whose period until the expiration date is shorter than the predetermined period (S145), and if there is, the parameter learning means 150 by designating the pharmacy and the medicine. Instruct them to learn to reduce inventory. The "predetermined period" may be set to, for example, 180 days, but it is not necessary to limit the period, and it may be determined for each drug while considering the interval from the time of manufacture to the expiration date. This confirmation and instruction is to prevent the expiration date from being exceeded. In addition, the inventory status determination means 140 confirms whether there are any medicines in the range indicating that the number of stocks is small (S145), and if there is, the parameter learning means by designating the pharmacy and the medicines. Instruct 150 to learn to increase inventory. The "range indicating that the predetermined number is small" may be set as, for example, half of the set lower limit of inventory, or may be set as a specific quantity such as 100 pieces. This confirmation and instruction is to prevent shortages. If either the expiration date is exceeded or the product is out of stock frequently, only one of them may be confirmed and instructed.

When the parameter learning means 150 is instructed to learn to reduce inventory, it performs learning according to a drug having addiction and a drug having no addiction as follows (S150). When the designated drug is addictive, the parameter learning means 150 changes the sales number information of the designated drug of the designated pharmacy in the direction of decreasing the number of sales, and designates the designated pharmacy. Change the repeat parameters of the drug to be less likely to be reused by the patient, or both. When the designated drug is not addictive, the parameter learning means 150 changes the sales number information of the designated drug of the designated pharmacy so that the number of sales decreases. For example, the set lower limit of inventory required by the set inventory calculation means 110 is reduced by the quantity of the drug whose period until the expiration date is shortened (or the quantity obtained by multiplying this quantity by a predetermined coefficient greater than 0 and less than 1). As such, the sales quantity information and the repeat parameter may be changed. For example, suppose that the calculation is performed as "set lower limit number = average number of sales per month x α + repeat parameter x number of drugs shown in the target prescription information". Then, when the prescription information for 300 addictive drugs A having a repeat parameter of 0.8 is used for the calculation of the set lower limit number of stocks, if the repeat parameter is changed to 0.75, the set lower limit number of stocks is set. Will be reduced by 15 (15 = 300 × (0.8-0.75)). Also, if the average number of sales per month is reduced, the set lower limit number will be reduced by the reduced number x α.

When the parameter learning means 150 is instructed to learn to increase the inventory, the parameter learning means 150 performs learning according to the addictive drug and the non-addictive drug as follows (S150). When the designated drug is addictive, the parameter learning means 150 changes the sales number information of the designated drug of the designated pharmacy in the direction of increasing the number of sales, and designates the designated pharmacy. Do both or one of changing the repeat parameters of the medicines that have been given to make them more likely to be reused by the patient. When the designated drug is not addictive, the parameter learning means 150 changes the sales number information of the designated drug of the designated pharmacy in the direction of increasing the number of sales. For example, the quantity of medicines that is insufficient because the set lower limit of inventory required by the set inventory calculation means 110 is out of the range indicating that the predetermined number is small (or the quantity is greater than 0 and less than 1 in advance). The number of sales information and the repeat parameter may be changed so that the quantity increases by the amount obtained by multiplying the determined coefficient. By performing such processing, the repeat parameter and the sales quantity information can be changed according to the inventory status, so that it is possible to prevent the expiration date and the shortage from occurring.

When the drug inventory management system 100 further includes the parameter updating means 200, the following processing is performed (see FIG. 4). The parameter updating means 200 specifies the pharmacy ID and the drug ID, and acquires the prescription information accumulated from the prescription information recording unit 193 (S220). The parameter updating means 200 obtains a repeat parameter, which is the ratio of the same patient purchasing the same drug again when the drug is addictive, from the acquired prescription information for each pharmacy and each drug, and when the drug is untimely. Obtains sales number information, which is information indicating the average number of sales, and when there is a timing, requests sales number information, which is information indicating the number of sales including changes in one year, and records it in the individual drug information recording department. (S200). For example, for the prescription information A, the prescription was issued between the date when the prescription was issued and the number of days included in the prescription information (the period during which the drug is used) with the same patient ID and the same drug ID. The repeat parameter may be obtained by confirming whether another prescription information B exists. In addition, the number of sales information may be created from the actual sales.

When the drug inventory management system 100 further includes the parameter initial setting means 300, the following processing is performed (see FIG. 5). To perform this process, the prescribing information also includes the patient's gender and age. The parameter initial setting means 300 specifies the drug ID and acquires the prescription information accumulated from the prescription information recording unit 193 (S320). In the acquisition of this prescription information, the prescription information specified by the drug IDs of all the pharmacies may be acquired, or a plurality of pharmacies that serve as models may be selected to acquire the prescription information. The parameter initial setting means 300 obtains repeat parameter basic data, which is the ratio of the same patient purchasing the same drug again at the same pharmacy for each patient's gender, for each group of predetermined ages, and for each drug with addiction. For example, for prescription information A, the prescription has the same pharmacy ID, the same patient ID, and the same drug ID, and is between the date when the prescription is issued and the number of days (the period during which the drug is used) included in the prescription information. The repeat parameter may be obtained by confirming whether another prescription information B for which is issued exists. The "predetermined age group" is a group of ages such as a group of 0 to 9 years old and a group of 10 to 19 years old. The parameter initial setting means 300 acquires information on the drug ID, the pharmacy ID, and the distribution of the sex and age of the patient from the pharmacy terminal 400 _n (S310). The parameter initial setting means 300 uses the repeat parameter basic data, the acquired drug ID, the acquired pharmacy ID, and the distribution of the sex and age of the patient to be used, for each drug with addiction at the pharmacy identified by the pharmacy ID. The repeat parameter is obtained and recorded in the drug individual information recording unit 192 (S300). It should be noted that the sales number information may be manually predicted and created from the population and the like.

According to the drug inventory management system 100 of the present invention, drugs are distinguished by attributes of addiction or non-addiction, and the number of drugs to be kept in inventory in consideration of the repeat parameter and the annual change in the number of sales. Find the lower limit. Therefore, it is less likely that the expiration date will be exceeded or the product will be out of stock, as compared with the case where a person sets the quantity of inventory as appropriate. If the adjustment information acquisition means 125 is provided, it is possible to respond to changes in consideration of trends and the like. If the set upper limit of inventory is set and the transferable information recording unit 194 is also provided, it is possible to transfer medicines between pharmacies, so that the expiration date can be further prevented from being exceeded. Further, if the parameter learning means 150 is also provided, the repeat parameter and the number of sales information can be changed according to the inventory status, so that it is possible to prevent the expiration date and the shortage from occurring. If the parameter updating means 200 is provided, the repeat parameter and the number of sales information can be appropriately updated from the past results. If the parameter initial setting means 300 is provided, the repeat parameter and the number of sales information can be predicted from the distribution of the sex and age of the patient predicted from the population distribution of the surrounding residents. Therefore, even a newly established pharmacy that has no past record can reduce the expiration date and shortage.
