DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for creating a process plan for a construction work, and more particularly to an apparatus for creating a process plan for a construction work used when examining a process plan for a large-scale construction work.

[0002]

2. Description of the Related Art In construction work, it is important to complete the construction work during a predetermined work period, but the amount of work and the amount of labor (number of workers) during the work period Changes depending on the process plan. As an example, in the cold district construction, the operation rate decreases in the winter season,
In order to compensate for the decrease in the amount of construction due to the decrease in the operation rate in the winter, a process plan that increases the amount of labor in the winter may be created.

However, it is not preferable that the amount of labor greatly fluctuates particularly in construction work in remote areas due to personnel planning. In addition, when the construction volume fluctuates, the amount of resources such as construction materials, electric power, and water also fluctuates.However, the amount of resources also increases in terms of the stable supply of materials, power supply facilities for construction work, and water supply facilities. It is preferably as constant as possible. In this way, the quality of the process plan affects the progress of the construction work, etc., especially in large-scale construction work, the builder changes the work period, labor amount and resource amount from the initial stage of the design of the structure. In many cases, a process plan is considered and prepared with consideration given thereto, and the prepared process plan is often presented to a constructor and a designer.

[0004] Further, when the design of a building is advanced and the design is changed from the design at the above-mentioned initial stage, or in a large-scale construction work such as a construction of a nuclear power plant, for example, other equipment such as a power supply facility is installed. If the process plan has been changed,
Frequently, process plans are modified or alternatives are created. In such a case, it is required that the process plan be prepared in a short time and in a thorough manner, but especially in a large-scale construction work requiring a long period of work and a large amount of resources and labor. The amount of information for creating a plan is large, and creating a process plan is a complicated task.

[0005] A large-scale planning effective procedure determining method such as a CPM (Critical Path Method) for determining a work procedure based on a large amount of information, and a PERT (Program Evaluati).
On and Review Techniqe) may be used to create a process plan, but it is premised that a series of operations are performed in a predetermined order. In the construction work, although there are some rules for the construction order of each process, the construction period of each process is allowed to overlap or the length of the overlapping period is allowed to expand or contract. In the construction of a plurality of structures, the structures may be constructed in any order.

However, when a process plan is created by using the above method, it is necessary to determine a new rule, a construction order, and the like in advance in order to conform to the method, and the process plan created by the method is not always required. It is not always the optimal process plan.

The present invention has been made in view of the above-mentioned facts, and has as its object to provide a construction work process planning device which can easily prepare an optimal process plan.

[0008]

In order to achieve the above object, a construction schedule planning apparatus according to the present invention comprises: a construction period of each construction stage; a resource amount related to a construction amount for each stage; Input means for inputting data including the amount of construction per unit labor amount and correction data for correcting the data, based on the data input by the input means and an operation rate determined according to the construction time, A process plan in which the transition of the amount of labor during the construction period is adjusted so that the construction period of the process matches the input construction period and the resource amount of each process is leveled throughout the construction period, The process plan in which the change in the resource amount during the construction period is adjusted so that the period matches the input construction period and the labor amount of each process is leveled throughout the construction period, and the labor amount of each process is Process engineering Creating means for creating at least one of the work period of each process and a process plan in which a change in the amount of resources within the work period is adjusted so as to be leveled throughout the period; and a process plan created by the creating means. Display means for displaying the result of integrating the amount of resources and the amount of labor for each predetermined period in each step in the process plan; and a correcting means for correcting the process plan based on the correction data input by the input means. doing.

[0009]

In the present invention, the input means includes, for example, the construction period of each step of the construction work, the amount of construction material, electric power, water and other resources and the amount of construction per unit labor related to the amount of construction for each step. Enter the data. Based on the input data and the operation rate determined according to the construction time, the creating means matches the construction period of each process with the inputted construction period and equalizes the resource amount of each process throughout the construction period. Thus, it is possible to create a process plan in which the transition of the amount of labor during the construction period is adjusted. Thereby, for example, when the concrete casting work is included in a certain process, even when the operating rate fluctuates during the construction period, the concrete amount, which is the resource amount related to the construction amount in the process, A leveled process plan is created throughout the construction period. For this reason, for example, a process plan suitable for construction work in which the amount of resources cannot be largely varied as a condition at the time of construction can be obtained.

[0010] Further, the creating means adjusts the transition of the resource amount during the construction period so that the construction period of each process coincides with the inputted construction period and the labor amount of each process is leveled throughout the construction period. It is possible to create a completed process plan.
In this case, it is possible to obtain a process plan suitable for construction work in which the amount of labor cannot be largely changed as a condition at the time of construction. In the case of construction work where the construction period is not so important, adjust the construction period of each process and the amount of resources during the construction period so that the labor amount of each process is leveled throughout the construction period of each process. It is also possible to create a completed process plan.

[0011] The process plan created by the creating means is displayed by the display means, and the result of integrating the amount of resources and the amount of labor for each predetermined period of each process in the process plan is also displayed. For this reason, the operator determines whether the transition of the resource amount and the transition of the labor amount are appropriate based on the accumulation result,
That is, it is possible to easily determine whether the created process plan is appropriate. After examining the process plan as described above, if the process plan is not appropriate, for example, move the construction time of a certain process by using the input means. Do
In large-scale construction work for constructing a plurality of structures, correction data such as changing the construction order of each structure is input.

The correction means corrects the process plan based on the correction data. Since the corrected process plan and the result of integrating the resource amount and labor amount of each process in the process plan for each predetermined period can be displayed again on the display means, it is possible to repeatedly examine and correct the process plan. In addition, it is possible to easily create an optimal process plan.

[0013]

Embodiments of the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the numerical values described in the present embodiment. FIG. 1 shows a construction schedule creation device 10 according to the present embodiment.

The process plan creation device 10 includes a personal computer 12 and various input / output devices connected to an input / output port 20 of the personal computer 12. The personal computer 12 includes a CPU 14 and an R
An OM 16, a RAM 18, and an input / output port 20 are provided, and these are connected to each other by a bus. In the present embodiment, as an input / output device connected to the input / output port 20, an external storage device 22 constituted by a recording medium such as a floppy disk, a hard disk, and the like, from which stored data is read and data is written; And a mouse 26 for inputting data and the like, and a display 28 for displaying a processing result.
And a laser beam printer 3 for printing processing results
0 and are used. The laser beam printer 30
Instead, an XY plotter or the like may be used.

A program for causing the personal computer 12 and each input / output device to function as the process plan creating device 10 is stored in the external storage device 22.
This program is read and executed when the power is turned on to the process plan creation device 10. The process plan creation device 10 is capable of creating a process plan for a large-scale construction work such as constructing a plurality of structures.
In large-scale construction work as described above, it is often the case that the processes of a plurality of constructions proceed simultaneously. For this reason, in order to avoid confusion on the process schedule and distinguish works for each building, the process plan creation device 10 calls one process a single process,
A group of single processes related to a specific building is recognized as one group process.

Next, as an operation of the present embodiment, a process of creating a process plan will be described with reference to the flowcharts of FIGS. The process plan review device 10 creates and stores a plurality of process plan plans, and displays an optional process plan plan as necessary.
It can be printed. In step 100 of the flow chart of FIG. 2, a process plan selection / input screen 40 as shown in FIG. 4 is displayed on the display 28, and a new process plan is prepared or a process plan already prepared is prepared. The operator to select whether to correct, display, or print. Also, when inputting a new process plan,
The user instructs to input the name of the plan and the construction start date via the keyboard 24.

In the next step 102, it is determined whether or not the current process plan draft is the first process schedule draft for a specific construction work. If the determination in step 102 is affirmative, in step 104, data specific to the specific construction work, that is, the name of a work place, the name of a group process, the name of a single process, the name of a material, the type of job (the type of labor) ). For example, when the name of the group process is to be input, a group process name data input screen 42 as shown in FIG. 5 is displayed, and the name of the group process is set for each building and trench (underground piping between the structures). Input. The name of the material is, for example, "rebar"
"Form", "concrete" and the like are input, and as the name of the occupation, for example, "form carpenter" and "rebar assembler" are input.

In the next step 106, a display color for each group process when displaying on the display 28 is set as a processing condition common to a plurality of process plans. This makes it possible to easily identify each group process when information on each group process, for example, the total time of the construction period, material, and labor of each single process is simultaneously displayed. Similarly, the display color is set for each single process name. After executing step 106, the process proceeds to step 108. If the determination in step 102 is negative, the process proceeds to step 108 without executing the processes in steps 104 and 106.

In steps 108 to 116, a process chart is prepared. That is, in step 108, a group process for creating a process chart is selected. In the next step 110, a process chart display screen 44 as shown in FIG. 6 is displayed, and a process line 46 is drawn for each single process constituting the selected group process. In the process line 46, the start point 46A indicates the start time of the single-step construction, the end point 46B indicates the end time of the single-step construction, and the position of the start point 46A and the end point 46B
Is designated, the process line 46 is drawn, and the construction period of a single process is input.

In the next step 112, the name and quantity of the material to be used are input as the name of the single process of the drawn process line 46 and the resource amount related to the construction amount of the single process.
Thus, as an example, in the process line 46 of FIG. 6, “trench body construction” is displayed near the process line 46 as a single process name, and the materials “form”, “reinforcing bar”, “concrete” and their quantities are used. Is displayed in the display field 48. In step 114, it is determined whether or not the input of the construction period and the materials has been completed for all the single processes constituting the single group process. If the determination in step 114 is negative, the process returns to step 110, and the processes in steps 110 to 114 are repeated until the determination in step 114 is affirmative.

If the determination in step 114 is affirmative, the process proceeds to step 116, where it is determined whether the input of the construction period and the materials for all the group processes has been completed.
If the determination in step 116 is negative, step 1
Returning to step 08, another group process is selected and the same processing is repeated.

When the input of the construction period and the materials for all the group processes is completed, the determination in step 116 is affirmed, and the process proceeds to step 118. In step 118, a step input screen 50 as shown in FIG. 7 is displayed, and a step is input. The step represents the amount of work performed by one person or a group of workers in January, that is, the amount of work per unit of labor. For example, the step in the case of a formwork carpenter is 10 [m ² / person ·
Moon] is one of the formwork carpenter has shown that to produce a mold of 10m ² in January. Also, the step is determined for each single process in consideration of the so-called difference in work efficiency for each single process. For example, when the place where the work is performed becomes an upper layer, the work efficiency is reduced due to the necessity of a scaffold, a long time for transporting materials, and the like. For this reason, the walk is set so that, for example, the work place becomes lower as the work place becomes the upper layer process.

In the next step 120, a monthly operating coefficient input screen 52 as shown in FIG. 8 is displayed, and a monthly operating coefficient for each half month during the construction period is input. The occupancy coefficient represents the occupancy rate of the entire construction work, which depends on the construction time.
For example, in the case of construction work in a cold region, the operation rate in the winter season is greatly reduced. In addition, the occupancy rate also decreases during periods of heavy rain and holidays. An operation coefficient considering these factors is input.

In step 122, a process plan review process is performed. This process plan study processing will be described in detail with reference to the flowchart of FIG. 3. In step 130, the first tabulation condition setting screen 54 shown in FIG. 9 is displayed, and the materials and labor to be totaled and displayed as a pile graph are displayed. Let me choose. For example, in FIG. 9, “form” is selected as the portion surrounded by the thick line frame, that is, the material to be totaled, and “formwork carpenter” is selected as the labor to be totaled.

In step 132, the second tabulation condition setting screen 56 shown in FIG. 10 is displayed, and the user selects which process is to be totalized for the materials and labor to be totalized selected in step 130. When “select by group” displayed in the tallying target selection column 58 is selected, it is determined that the material amount and the labor amount in the specific group process are to be tallyed. When “selection by single process” is selected, it is determined that the material amount and labor amount of a specific single process are to be counted. In addition, the calculation target selection column 5
If the display of No. 8 is not selected, it is determined that the material amounts and labor amounts of all the processes are to be counted.

At step 134, the step and the monthly operating coefficient related to the tallying object selected at step 132 are fetched. In the next step 136, it is determined whether or not the counting method is material fixed. The tallying method is designated by selecting either “fixed labor” or “fixed material” in the tallying method selection column 60 in FIG. If the determination in step 136 is affirmative, the process proceeds to step 138, in which the construction period is fixed and the material amount is constant in each month for each of the single or multiple single processes to be counted. The assignment of the amount of labor when assigned to is calculated. For example, the conditions, aggregate materials: mold area aggregates to labor: formwork carpenter aggregate target of the construction period: material amount of three months the construction period: 900 m ² steps consuming: 10.00 m ² / person-month operation of each month Coefficient: 0.5 1.0 Assuming that 1.0, the amount of material every month (constant) = 900 ÷ 3 = 300 m ² The amount of labor in the first month = 300 ÷ 10.00 ÷ 0.5 = 60 people The amount of labor in the second month = 300 ÷ 10.00 ÷ 1.0 = 30 people Labor amount in the third month = 300 ÷ 10.00 ÷ 1.0 = 30 people The labor amount allocation is calculated as described above (FIG. 15).
(See (A) and (B)). As described above, when “material fixation” is set, the amount of labor in each month is adjusted and allocated so that the amount of construction and the amount of material related thereto each month are constant. In the above example, the operation coefficient of the first month is set to a low value, and in consideration of this, the work amount is assigned so that the amount of labor in the first month is increased.

If the determination in step 136 is negative, in step 140, the construction period is fixed and the amount of labor is constant for each month for each of the single or multiple single processes to be counted. Calculate the allocation of the material amount when allocating so that For example, in the case of the same conditions as above, monthly labor (constant) = 900 ÷ 10.00 ÷ (0.5 + 1.0 + 1.0
) = 36 people Material amount in the first month = 36 x 10.00 x 0.5 = 180 m ² Material amount in the second month = 36 x 10.00 x 1.0 = 360 m ² Material amount in the third month = 36 x 10.00 x 1.0 = 360m ² The material amount allocation is calculated as described above (see FIG. 15).
(See (C) and (D)). In this way, if the “fixed labor” is set, the amount of construction and the amount of materials related to each month are adjusted and allocated so that the amount of labor is constant every month. In the above example, the allocation is performed so that the amount of materials in the first month is reduced. In the next step 142, the amount of materials and the amount of labor allocated for all the single processes to be counted are integrated,
A pile graph 6 as shown in FIG. 11 using the integration result as an example.
Display as 2.

In step 144, based on the displayed pile graph 62, it is determined whether the transition of the material amount and the labor amount is appropriate. For example, if "fixed labor" is used, the amount of material in each month will vary, but if the variation is extremely large, or if the peak value of the amount of material exceeds the limit of material supply as a condition at the time of construction, etc. In this case, it is determined that the changes in the material amount and the labor amount are not appropriate, and correction data for correcting the construction time of the single process is input. When the correction data is input, the determination in step 144 is denied, and the process proceeds to step 146. In accordance with the input correction data, the work time of the single process is moved, or the overlap of the single processes is expanded or contracted. Modify the plan.

As an example, a single step 6 shown in FIG.
Regarding 4 and 66, when attention is paid to the pile graph of the material amount or the labor amount shown in FIG. 12B, the material amount or the labor amount of the portion corresponding to the single process 66 is prominent. Therefore, it can be determined that the construction period of the single process 66 is too short for the construction amount of the single process 66. In this case,
For example, an overlap between the construction periods of the single process 64 and the single process 66 can be provided (see FIG. 12C). It is necessary for the operator to judge whether or not the length of the portion where the construction period overlaps is appropriate. As a result, as shown in FIG. 12D, the material amount or the labor amount of the pile graph is leveled to some extent. You. In addition, by changing the construction method of the construction, it is also possible to change the construction order of the single process and to perform the leveling.

After executing step 146, step 1
Returning to 30, the allocation of the material amount and the labor amount is calculated again based on the process plan corrected in the steps 130 to 142, and the allocated material amount and the labor amount are integrated and displayed as a pile graph.

For example, when it is determined that the transitions of the formwork area and the formwork man-hour are appropriate and the determination of step 144 is affirmative, the process proceeds to step 148 to determine whether the transition of all the materials and labor is appropriate. judge. If the determination in step 148 is denied, the process returns to step 130 to determine whether the transition of other materials and labor is appropriate in the same manner as described above, and if the correction data is input, the transition is appropriate. Judge that it is not, and correct the process plan.

If the determination in step 148 is affirmative, the process proceeds to step 150, in which it is determined whether the transition of each material amount and each labor amount during the entire construction period is appropriate.
It is determined that the transition of each material amount and each labor amount is not appropriate,
When the correction data for correcting the process plan is input, the determination in step 150 is denied, and in step 152, the construction start date and time of the group process are determined based on the input correction data.
Correct the construction order of the group process, etc., and return to step 130.

As described above, by modifying the overlapped single process, the start date and time of the group process, the construction order, etc., with respect to the created process plan while referring to the changes in the material amount and the labor amount, the optimal process plan is obtained. A process plan can be created in a short time.

If the determination in step 150 is affirmative, the process plan reviewing process ends, and the routine goes to step 124 in the flowchart of FIG. In step 124, as shown in FIGS. 13 and 14, for example, the process chart 68 and the pile graph 70 of the created process plan are printed by the laser beam printer 30. One process plan is created in this way, but it is also possible to separately create a process plan in the case of using another method and compare the two. In addition, when a change in the design of a building, a change in the process of another facility, or the like occurs, it is also possible to modify the already created process plan and present it to the constructor and the designer.

In this embodiment, the construction period is fixed.
Calculate the amount of labor when allocating so that the amount of material in each month is constant, or calculate the amount of labor when the work period is fixed and the amount of labor in each month is constant. Was calculated to calculate the process plan, but if the construction period can be expanded or contracted to some extent,
A process plan may be created by adjusting the construction period and the amount of materials so that the amount of labor in each month is constant. For example, under the above conditions, the limit of the amount of labor each month is 3
0 people, and if the construction period to some extent elastic, i.e., materials to aggregate: mold area aggregate to labor: Material amount of formwork carpenter the construction period: 900 m ² steps consuming: 10.00 m ² / person, month each month Limit of the amount of labor of: 30 people Operating coefficient of each month: 0.5 1.0 1.0 0.5 Under the above conditions, the construction period is extended by one month because the construction is not completed in 3 months, and the amount of labor per month (constant) = 900 ÷ 10.00 ÷ (0.5 + 1.0 + 1.0 +
0.5) = 30 First month material quantity = 30 × 10.00 × 0.5 = 150m ² Second month material quantity = 30 × 10.00 × 1.0 = 300m ² Third month material quantity = 30 × 10.00 × 1.0 = 300 m ² Material amount in the fourth month = 30 × 10.00 × 0.5 = 150 m ² The allocation of labor and material amount can be calculated as described above (see FIGS. 15 (E) and (F)).

Further, in this embodiment, the resource amount related to the construction amount has been described using the material amount such as "form area" and "concrete amount", but the present invention is not limited to this. , Power consumption and water usage as resources
It is also possible to create a process plan in consideration of these transitions.

Further, in this embodiment, the process plan is prepared so that the amount of materials or labor is constant during the construction period of a single process. If it is anticipated that concentration will occur in advance, a process plan may be created so that, for example, the amount of concrete is constant in the latter half of the single process.

[0038]

As described above, according to the present invention, the construction period of each process matches the entered construction period based on the input data and the operation rate determined according to the construction time. A process plan in which the amount of labor during the construction period is adjusted so that the resources of the process are leveled throughout the construction period,
A process plan in which the amount of resources during the construction period has been adjusted so that the construction period of each process matches the entered construction period and the amount of labor in each process is leveled throughout the construction period, and the amount of labor in each process Creates at least one of the work period of each process and a process plan in which the change in the amount of resources during the work period is adjusted so that the process plan is equalized throughout the work period of each process. Since the result of integrating the amount of resources and the amount of labor for each predetermined period of each process is displayed, and the displayed process plan is corrected based on the input correction data, it is easy to consider an optimal process plan. Excellent effect is obtained.
