Description

The present invention relates to a system for allocating production planning lines, and more particularly to a system for appropriately adding a planning line in response to an order or the like.

(Prior Art) In a conventional production planning line allocation system, a central control device determines a storage plan for each completed line based on information such as order quantity, delivery date, stock quantity, and work in process for a predetermined time period.
For example, a month is set as a unit. In this case, when the number of orders for one product is large, the processing capacity of one completed line to which the product is to be allocated exceeds the processing capacity of one completed line, or the processing of the completed line is also performed in relation to the storage plan of another product already allocated. When the capacity was exceeded, the stocking plan for the product was performed on multiple completed lines.

(Problems to be Solved by the Invention) However, the above-mentioned conventional allocation system can perform a monthly storage plan and a completed line load plan.
Automatically reset daily receipt plans and completed lines in response to urgent orders, for example, because these monthly plans are not linked to them. Therefore, there is a problem that the customer's delivery date may not be met.

The present invention has been made in order to solve the above-mentioned conventional problems. Even in the event of an urgent order, etc., a planning line is appropriately added, and a daily warehousing plan and a load plan of a completed line are automatically set. It is an object of the present invention to provide a production planning line allocation system capable of reliably setting a production schedule line by preventing the delay of a delivery date.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a plurality of planning lines capable of performing the same processing on the same product, and at least a signal indicating a product order information. A central control device for designating a planning line from among a plurality of planning lines and the number of plans for each planning line in a predetermined period unit, wherein the central control device includes a signal representing the order information. When the sum of the planned numbers of the respective planned lines specified according to the above is smaller than the number of orders for the product, additional and specified plan lines other than the already-specified planned lines are added, and the additionally specified planned lines are also specified. And for each of the already specified planning lines, the number of plans in the unit of the predetermined period and the number of plans in the unit of a period shorter than this.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows the overall configuration of a production planning line allocation system according to the present invention. In the figure, reference numeral 1 denotes a central control unit. The central control unit 1 includes a factory calendar master 2 storing data of actual operation days of the factory, product types, product specifications, planning lines, and the like. A planning line master 3 that stores the relationship with the priority order and the like, a processing capability master 4 that stores the processing capability of each planning line, and the like are connected, and these pieces of information are input.

The central control device 1 uses the information described above and the order information to execute the planning lines A, B, C,.
Is specified, and the number of plans in each month and the number of plans in each day of each planning line are specified. These are stored as an already-loaded plan, and the signal is supplied to each planning line.

FIG. 2 shows a flowchart of a program executed by the central control device 1 for designating the planned lines and the planned numbers of the planned lines on a monthly and daily basis.

First, the order information of the product is input (step 201), and the number of storage instructions N _i (i = 1 to 3) is set from the order information as shown in FIG. (Step 202). Next, a planning line, for example, planning lines A, B, and C is designated based on the number of storage instructions N _i , the priorities of the already loaded plans and the planning lines (step 203),
The number of plans M per month for each specified planning line
_Xi (= M _Ai , M _Bi , M _Ci ) is specified (step 204). It should be noted that the planned number M _Xi per month is specified so as not to exceed the _permissible number M _Ximax per month for processing each planned line.

Then, it is determined whether or not planned quantity of the sum? M _Xi monthly is Receipt instruction speed N _i or monthly (step 205), negation is the answer (No), i.e. specified above for each planning line when the sum? M _Xi plan number is insufficient with respect to goods receipt instruction speed N _i of product planning line X (e.g. line D) specified by newly added (step 206), returns to step 204 Specify the planned number M _Xi (= M _Ai , M _Bi , M _Ci , M _Di ) in monthly units. As described above, by specifying the planned number M _Xi on a monthly basis, the planned number of each planning line can be specified on a monthly basis so that there is no shortage for the number of product orders.

If the answer in step 205 is affirmative (Yes), that is, ΣM _Xi ≧ N _i
There satisfied, therefore, when the planned quantity of the sum? M _Xi of the specified each plan line is product warehousing instruction speed N _i above is
Proceed to step 207 and thereafter, and specify the planned number M per month specified above.
Based on _Xi , the number of plans m _Xj on a daily basis for each planning line is specified.

First, in step 207, the warehousing instruction speed N _i and daily goods receipt plans monthly set at step 202, for example, as shown in FIG. 4, receipts instruction number of daily n _{j (j} = 1
To 31). In this case, the sum Σn _j of the number of storage instructions on a daily basis is set to be the sum ΣM _Xi of the planned number of each planning line on a monthly basis specified in step 204.

Next, the number of plans m _Xj (= m _Aj , m _Bj , m _Cj , m _Dj ) per day is specified for each planning line specified in step 204 (step 208). Next, for each planning line, the sum of the number of plans Σm _Xj is specified in step 204,
It is determined whether or not the corresponding monthly planned number M _{Xi is} greater than or equal to (Step 209). For example, if FIG. 4 shows the planned number of daily units for one month in the future, in the case of line A,
It is determined whether or not m _Aj = m _A1 + m _A3 + ·· m _Aj + ·· is _{equal to} or greater than M _A1 . If this answer is affirmative (Yes), that is, if Σm _Xj ≧ M _Xi is satisfied for any of the planned lines, the designation of the daily planned number m _{Xj for} the relevant planned line is terminated.

If the answer in step 209 is negative (No), that is, Σm _Xj <M _Xi
Is satisfied, the process proceeds to step 210, and for each day, the sum of the number of plans of each planning line up to that day Σm
_Xj is, determines whether or not the day to day basis Receipt instruction number of the sum .SIGMA.n _j or more. In this case, the total sum Σm _Xj of the respective planning lines includes the already-specified plan lines for which the designation of the planned number m _Xj per day has been completed due to the affirmation of the answer in step 209 (Yes). Also, this sum Σm
_Xj is the case for example the second day of the fourth diagram of (j = 2), .SIGMA.m _Xj
= M _A1 + m _B1 + m _C2 .

If the answer to step 210 is negative (No), that is, Σm _Xj <Σn _j is satisfied for any day, and the planned number m _Xj is insufficient, step 208 is executed and affirmative (Yes), that is, Σm _{when Xj} ≧ _{Σn j} is satisfied, and the program is finished.

As described above, by specifying the planned number m _j per day, it is possible to specify the planned number per day without running short for each planning line and each day.

In the present embodiment, the additional designation of the plan line is performed only when the number of plans in units of months is designated. However, the present invention is not limited to this. For example, in addition to this, the number of plans in units of days is designated. As a result, when the specified number of plans exceeds the permissible processing number of the planned lines per day, additional designation of the planned lines may be performed.

(Effects of the Invention) As described in detail above, according to the present invention, when a new order is received, the planned number of machining processes is not insufficient for the number of orders, and the processing capacity of each planned line Thus, an effect is obtained that a plan line can be added as appropriate so as not to exceed.
