Description

  The present invention relates to a production plan creation system and a program for executing the production plan creation system.

  When creating a long-term production plan for products produced through a number of processes, the production plan period is generally divided into predetermined periods (hereinafter referred to as “unit periods”) and the equipment used. A method of adjusting the load of each unit period (load accumulation, load collapse) is used. Conventionally, a production plan creation system using this method is known (see, for example, Patent Document 1).

  Such a production plan creation system accumulates the process information of each process input by the administrator in the database of the arithmetic unit. Here, the process information of each process is, specifically, data that collects a work start date, a work end date, equipment to be used, man-hours, and the like of each process. And the process information which belongs to each unit period is extracted from this database, and the load of each unit period is calculated by totaling (stacking) the man-hours of each process information. When the calculated load exceeds the preset equipment capacity, the load of each unit period is adjusted by changing the allocation of the process (that is, by performing hill-climbing), and the load is leveled.

Japanese Patent Laid-Open No. 7-141435

  By the way, when manufacturing large equipment such as a gas turbine, for example, the number of processes required for manufacturing one equipment reaches several thousand processes. Therefore, when dozens of such large devices are manufactured per year, the number of processes per year is several hundred thousand to several million processes, and the process information accumulated in the database of the production planning apparatus described above is also enormous. It becomes. For this reason, when performing load stacking and mountain collapse for each unit period as described above, each time, the corresponding process information must be extracted and processed from a large amount of process information accumulated in the database, There is a problem that data processing takes time and work efficiency is poor.

  The present invention has been made in view of the above, and an object of the present invention is to provide a production plan creation system and program capable of speeding up the calculation of load accumulation and mountain collapse of a large amount of process information.

  In order to solve the above-described problems and achieve the object, the production plan creation system according to the present invention is a system for creating a production plan of a product produced through a plurality of processes, and each of which is input by a user. A process information storage unit that stores process information including a work start date, a work end date, equipment used, and man-hours of the process, and the set production plan period is divided into unit periods having a predetermined time width, and the process information storage Period-by-period process information creating unit that creates period-by-period process information by dividing the man-hours of each process information stored in the unit for each unit period, and period-by-period processes in which the period-by-period process information belonging to each unit period is aggregated Of the process information aggregate storage unit by period for storing the information aggregate and the process information by period belonging to the process information aggregate by period for each unit period, the man-hours of the process information by period using the predetermined equipment are totaled Total mechanic A calculation unit, and having a.

  In this production plan creation system, when the load of a process of a certain unit period in a predetermined facility is crushed and piled up, only the process information aggregate by period of the unit period is read from the process information aggregate storage unit by period. The process information by period stored in the read process information aggregate by period is processed. For this reason, the amount of data to be processed can be reduced as compared with the conventional case where the corresponding process information is extracted from all the process information stored in the process information database and processed. As a result, it is possible to speed up the calculation of load piles and mountain breaks, and it is possible to improve work efficiency when creating a production plan.

  In the production plan creation system according to the next aspect of the present invention, when new process information is added to the process information storage unit, the process information creation unit by period calculates the man-hour of the added process information for each unit period. The divided period-by-period process information is created, and the created new period-by-period process information is added to the period-by-period process information aggregate in the corresponding unit period in the period-by-period process information aggregate storage unit.

  In this production plan creation system, when process information is added by a user, the process information is divided to create process information by period, and the process information by period is collected by the period-specific information aggregate of the corresponding unit period. Add to. For this reason, when recalculating the pile after the addition, only the data of the period-specific process information aggregate including the added period-specific process information needs to be processed, so the recalculation of the pile is processed at high speed. It becomes possible.

  In the production plan creation system according to the next aspect of the present invention, when the work start date and the work end date of the process information stored in the process information storage unit are changed, the process information creation unit by period is changed. Create process information by period that divides the man-hours of process information for each unit period, delete process information by period before change from the process information aggregate storage unit by period, and process information by period after change, It adds to the process information aggregate according to period of the applicable unit period in the process information aggregate according to period.

  When the process information stored in the process information storage unit is changed by a user, this production plan creation system divides the process information to create period-specific process information, and the period-specific process information aggregate storage unit The process information by period before the change is deleted from the process information, and the process information by period after the change is added to the information aggregate by period of the corresponding unit period. For this reason, when recalculating the pile after the change, it is only necessary to process the data of the period-specific process information aggregate including the changed period-specific process information, so the pile recalculation is processed at high speed. It becomes possible.

  A production plan creation system according to the present invention includes a graph creation unit that creates a load pile graph based on the total man-hour of each unit period obtained by the total man-hour calculation unit, and a screen that displays the load pile graph on a display unit A display processing unit is further provided.

  According to this production plan creation system, when process information is changed or added, the load pile graph can be displayed on the display screen in a short time.

  A production plan creation program according to the present invention causes a computer to execute the production plan creation system according to any one of claims 1 to 4.

  According to this production plan creation program, the above production plan creation system can be realized using a computer.

  In the production plan creation system and the production plan creation program according to the present invention, when the load of the process of a certain unit period is crushed and piled up, the process information set by period of the unit period from the process information aggregate storage unit by period Only the body is read, and the period-specific process information stored in the read period-specific process information aggregate is processed. For this reason, the amount of data to be processed can be reduced as compared with the conventional case where the corresponding process information is extracted from all the process information stored in the process information database and processed. As a result, it is possible to speed up the calculation of load piles and mountain breaks, and it is possible to improve work efficiency when creating a production plan.

  Embodiments of a production plan creation system according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments. The constituent elements of this embodiment include those that can be easily replaced by those skilled in the art or those that are substantially the same.

  FIG. 1 is a block diagram showing a configuration of a production plan creation system 1 according to the present embodiment. The production plan creation system 1 is a system suitable for creating a long-term production plan for products produced through a number of processes. Below, the example applied to the manufacturing facilities of turbines, such as a gas turbine and a steam turbine, is demonstrated.

  The number of processes required for manufacturing one turbine is about 5000 processes. For example, when 30 units are manufactured in one year, the total number of processes in one year reaches 150,000 processes. In addition, there are usually about 40 types of equipment used for manufacturing one turbine. In the production plan creation system 1 of the present embodiment, the production plan period is divided into periods (unit periods) having a predetermined time width, and the load of each unit period is adjusted for each equipment used (load pile, load collapse). Apply the method you want. In the following, the unit period is “season”. That is, when one month is divided into three periods of early (1st to 10th), middle (11th to 20th), and late (21th to 30th), and the load of each season in each equipment used is calculated. Will be described.

  Here, the “load” is the total work time planned to be processed by a specific facility (or facility group) in a certain season, and in this embodiment, the number of man-hours for each process is a load. Further, “stacking” means that a plurality of processes are assigned to a unit period, and the man-hours (loads) of the processes assigned to each unit period are accumulated. In order to avoid concentrating work in a certain period, “mountain breakout” means that if the man-hour (load) per unit period exceeds the equipment capacity, the process is moved to another unit period. It means to fit within the equipment capacity.

  A production plan creation system 1 illustrated in FIG. 1 includes an arithmetic device 10, an input unit 11, and a display unit 12. The arithmetic device 10 is specifically an information processing device such as a personal computer or a workstation, and includes a control unit 20 and a storage unit 30.

  The control unit 20 temporarily stores a CPU (Central Processing Unit) that executes a processing program, a ROM (Read Only Memory) in which a processing program to be executed by the CPU is recorded in advance, an operation parameter of each process, and the like. This is realized using a RAM (Random Access Memory). The control unit 20 includes a process information creation unit 21 that creates process information including the work start date, work end date, used equipment, and man-hours of each process input by the user, and sets the set production plan period to “season”. The process information creation unit (seasonal process information creation part) 22 for creating seasonal process information that divides and divides the man-hours of each process information into seasons, and the index number assignment for assigning an index number to the seasonal process information A unit 23, a total man-hour calculating unit 24, a graph creating unit 25, and a screen display processing unit 26.

  The storage unit 30 is realized using a recording medium such as a hard disk, stores data instructed to be stored by the control unit 20, and transmits data instructed to be read by the control unit 20 to the control unit 20. The storage unit 30 includes a process information database (process information storage unit) 31 that is an area for storing the process information 31D created by the process information creation unit 21 and the seasonal process information 32D created by the seasonal process information creation unit 22. Seasonal process information database 32 (seasonal process information database 32), which is an area for storing seasonal process information database 32 that is an area to be stored and seasonal process information aggregate 33G in which seasonal process information belonging to each season is aggregated An aggregate storage unit) 33.

  The input unit 11 includes a pointing device such as a mouse and a device such as a keyboard, and inputs various information to the control unit 20 by an input operation by a user. The display unit 12 includes various types of displays such as a liquid crystal display, and displays an image processed by the screen display processing unit 26. Here, the image displayed on the display unit 12 is, for example, a graphical user interface (GUI) for a user to input various information using the input unit 11, a load pile graph, a Gantt chart, or the like. This is a graph.

Hereinafter, processing of each unit in the control unit 20 will be described in detail. The process information creation unit 21 creates process information 31D for each process based on the data input from the input unit 11, and attaches a process number (1... N,...) To each process information 31D. Store in the information database 31. The table (a) of FIG. 2 represents an example of the process information 31D stored in the process information database 31. As described above, the number of processes required for manufacturing one turbine is approximately 5000 processes, and the total number of processes per year is expected to exceed approximately 100,000 processes. In the table of FIG. for convenience of explanation, it shows only six process information _31D 1 ～31D ₆ from step No. 1 to 6. (A) As shown in the table, the process information 31D is data in which a process number, a work start date, a work end date, equipment used, and man-hours are grouped. The work start date, work end date, equipment used, and man-hour are data input from the input unit 11 by the user. For example, the process information 31D ₁ of process number 1 has a work period of 7 days from June 1, 2009 to June 7, 2009, the equipment used is A, and the man-hour is 70 hours.

  Returning to FIG. 1, the season-specific process information creation unit 22 divides each month in the set production plan period (for example, three years) into the seasons (early, middle, and late), and the process information from the process information database 31 described above. 31D is read, and seasonal process information 32D is generated by dividing the man-hours of the read process information 31D into each season.

  The index number assigning unit 23 assigns an index number that is different from the process number to the seasonal process information 32D created by the seasonal process information creation unit 22, and the seasonal process information 32D to which the index number is given is seasonal process information. Store in the database 32. In parallel with this process, the index number assigning unit 23 stores the index number of the seasonal process information 32D in the seasonal process information aggregate 33G corresponding to the season in the seasonal process information aggregate database 33.

Hereinafter, the processes of the seasonal process information creation unit 22 and the index addition unit 23 will be described in detail with reference to FIG. Shown in FIG. 2 (b) table, a season-specific process information _32D 1 _{~32D 9} the steps of the process information _31D 1 _{~31D 6} step numbers 1-6 obtained by dividing the season indicated in (a) Table It is the table shown. The table (c) of FIG. 2 shows a seasonal process information aggregate 33G in which the index numbers of the seasonal process information 32D belonging to each season are gathered in the seasonal process information 32D of the table (b). It is.

For example, process information 31D ₂ of the process number 2 of (a) table, work period is June 15, June 8, 2009 to 2009, spans the mid-and early June. In this way, when the work period of the process information extends over two or more seasons, the seasonal process information creation unit 22 divides the man-hour 64 hours of the process information 31D ₂ into early June and mid June. I do. In the division, man-hours are proportionally distributed for each season. That is, since the man-hour 64 hours is performed for 8 days from June 8 to June 15, the man-hour per day is 8 hours (64 hours / 8 days). Therefore, the man-hour in early June (June 8-10) is 8 hours x 3 days = 24 hours, and the man-hour in mid-June (June 11-15) is 8 hours x 5 days = 40 It will be time. By performing the above-described processing, the seasonal process information creation unit 22 performs the process number 2, the work period early June, the used equipment B, and the seasonal process information 32D ₂ including the man-hour 24, the process number 2, and the work. In the middle of June, seasonal process information 32D ₃ is created with the equipment B and man-hours 40 as a group.

The index number assigning unit 23 assigns index numbers ₂ and ₃ to the seasonal process information 32D _{2 in} early June and the seasonal process information 32D ₃ in mid June, respectively, and stores these in the seasonal process information database 32. . (A) Step No. in the table. 3 process information 31D ₃ , process no. The process information D6 of No. ₆ is processed in the same procedure as described above.

(B) As shown in the table, the seasonal process information 32D is data that includes an index number, a process number, the season in which the work is performed, the equipment used, and the number of man-hours. Note that the seasonal process information 32D also has information on the work start date and end date, but in the table (b), the work start date and end date are omitted, and the season information (early June, mid- Only () is shown. For example, season-specific process information 32D ₂ of the index number 2, work start date: June 8, 2009, work End Date: has the information that on June 10, 2009, omitted in (b) Table ing.

On the other hand, the process information 31D ₁ of process number 1 in the table (a) is only in the beginning of June from June 1, 2009 to June 7, 2009, and does not straddle two or more seasons. . Therefore, Shun-specific process information creation unit 22 does not perform the process of dividing the number of steps Step information 31D _1, step number 1, the working period early June, Shun-specific process information using equipment A, the steps 70 and human unity to create a 32D _1.

The index number assigning unit 23 assigns the index number 1 to the seasonal process information 32D ₁ and stores it in the seasonal process information database 32. (A) Step No. in the table. 4 process information 31D ₄ , process no. The process information D5 of ₅ is also processed in the same procedure as described above.

In parallel with the above processing, the index number assigning unit 23 stores the index number and the season information in the seasonal process information aggregate 33G corresponding to the season in the seasonal process information aggregate database 33. For example, since the season-specific process information 32D ₁ , 32D ₂ , and 32D ₆ all have a work period of early June 2009, the index number assigning unit 23 includes the index numbers 1, 2, and 6 and seasonal information (early June). ), and stores of early June to season-specific process information aggregate 33G _1. Similarly, the seasonal process information 32D ₃ , 32D ₄ , 32D ₇ , and 32D ₈ are all in the middle of June 2009, so the index information is ₃ , ₄ , ₇ , and 8 and the seasonal information (mid-June) , and stores of mid-June to season-specific process information aggregate 33G _2. Similarly, the seasonal process information 32D ₅ and 32D ₉ are both in the end of June 2009, so the index numbers 5 and 9 and the seasonal information (late June) are used, and the seasonal process information in late June is used. and stores it in the aggregate 33G _3.

  Returning to FIG. 1, the total man-hour calculation unit 24 reads the seasonal process information aggregate 33G from the seasonal process information aggregate database 33, and assigns the predetermined facility among the index numbers belonging to the seasonal process information aggregate 33G. By summing up the corresponding man-hours, the sum of the man-hours allocated in each season in the equipment (load) is calculated.

Here, the process of the total man-hour calculation unit 24 will be specifically described with reference to FIG. For example, when calculating the total man-hours of equipment A at the beginning of June, the total man-hour calculating unit 24 reads the seasonal process information aggregate 33G ₁ at the beginning of June from the seasonal process information aggregate database 33 shown in FIG. . Then queries the use equipment and steps corresponding to the index number 1, 2, 6 stored in the season-specific process information aggregate 33G _1, the season-specific process information database 32 shown in FIG. Then, the man-hours 70 and 28 of the index numbers 1 and 6 corresponding to the equipment A are received from the seasonal process information database 32, respectively, and the man-hours 70 and 28 are totaled to obtain a total man-hour 98.

Returning to FIG. 1, the graph creating unit 25 creates a Gantt chart, a load pile graph, and the like by graphing the seasonal total man-hours of each equipment used calculated by the total man-hour calculating unit 24. (D), (e), and (f) of FIG. 3 show examples of graphs and tables created by the graph creation unit 25. FIG. FIG. 3 (d) is a Gantt chart of the process information _31D 1 _{~31D 6} step numbers 1-6 shown in the (a) Table 2. Further, (e) in FIG. 3 is a man-hour table created on the basis of the process information _32D 1 _{~32D 9} of the index number 1 to 9 shown in (b) table of FIG. Moreover, (f) of FIG. 3 is a man-hour table of facilities A, B, and C created based on the seasonal process information 33G _{1 to} 33G ₃ in the table (c) of FIG.

Next, the process of the control part 20 when process information is changed by the user is demonstrated using FIGS. In the following, the work start date of June 11 and the work end date of June 15 of the process of process number 5 shown in the table of FIG. 2 are the work start date of 6 as shown in the table of FIG. A case will be described in which the work date is changed to June 10 and June 14th. As shown in the table (a) of FIG. 4, the process with the changed process number 5 has an operation period from June 10, 2009 to June 14, 2009, straddling the beginning and the middle of June. Yes. Therefore, the seasonal process information creation unit 22 performs a process of dividing the 40-hour man-hour of the process information 31D ₅ into early June and mid June. According to the above-described method, the man-hour in early June (June 10) is 8 hours × 1 day = 8 hours, and the man-hour in the middle of June (June 11-14) is 8 hours × 4 days = 32 It will be time. Seasonal process information creation unit 22 includes process number 5, work period early June, use equipment B, seasonal process information 32D ₁₀ as a group, process number 5, work period mid-June, use equipment B, seasonal process information 32D _{11 in} which man-hours 32 are grouped is created.

The index number assigning unit 23 assigns index numbers ₁₀ and ₁₁ to the seasonal process information 32D ₁₀ and the seasonal process information 32D ₁₁ , respectively, and as shown in the table (b) of FIG. 32. Along with this processing, the index number assigning unit 23 deletes the seasonal process information 32D ₇ before the change (see the table (b) in FIG. 2) from the seasonal process information database 32.

In parallel with the above processing, the index number assigning unit 23 obtains the index number 10 and the season information (early June) as 6 in the seasonal process information aggregate database 33 as shown in the table (c) of FIG. stored in the season-specific process information aggregate 33G ₁ of early month, the index number 11 and season information (early June), the mid-June in season-specific process information bundle database 33 in season-specific process information aggregate 33G ₂ Store. With this process, the index number assigning unit 23 deletes the index number 7 (see the table (c) in FIG. 2) from the seasonal process information aggregate database 33.

The total man-hour calculation unit 24 recalculates the total man-hours of the use equipment B at the beginning of June and the middle of June. That is, reading a season-specific process information set by body from the database 33 of early June Shun process information aggregate 33G ₁ and 6 Mid season-specific process information aggregate 33G _2, stored in the season-specific process information aggregate 33G ₁ The used facility and man-hour corresponding to the index numbers 1, 2, 6, 10 are inquired of the seasonal process information database 32. Then, the man-hours 24 and 8 with the index numbers 2 and 10 corresponding to the equipment B are received from the seasonal process information database 32, respectively, and the man-hours 24 and 8 are totaled to obtain a total man-hour 32. Likewise, the equipment used and effort corresponding to the index number 3,4,11,8 stored in season-specific process information aggregate 33G _2, queries the season-specific process information database 32, from season-specific process information database 32 The man-hours 40 and 32 of the index numbers 3 and 11 corresponding to the equipment B are received, and the total man-hour 72 is obtained.

  The graph creation unit 25 graphs the total man-hours of the used equipment B recalculated by the total man-hour calculating unit 24 at the beginning of June and the middle of June, so that (d), (e), ( As shown in f), the Gantt chart, the man-hour table, and the load pile graph are each updated. In order to make the changed part easy to understand, the changed part is indicated by a thick frame in (d) of FIG. 5, and the changed numbers are indicated by circles in (e) and (f).

  When manufacturing a large-sized device such as a turbine, the number of steps required for manufacturing one device reaches several thousand, so the number of steps per year is expected to be several hundred thousand to several million. In the conventional system, an enormous number of process information 31D is managed only by the process information database 31. For this reason, when adjusting the load, such as changing the work period described above, the corresponding process information must be extracted from the hundreds of thousands of process information 31D stored in the process information database 31 and processed. The data processing takes time and the work efficiency is poor. On the other hand, in the production plan creation system 1 of the present embodiment, when adjusting a load such as a change in work period, the seasonal seasonal process to be adjusted from the seasonal process information aggregate database 33. Only the information aggregate 33G may be read, and the seasonal process information 32D stored in the read seasonal process information aggregate 33G may be processed. Therefore, the amount of data to be processed can be reduced as compared with the conventional case. As a result, it is possible to speed up the calculation of load piles and mountain breaks, and it is possible to improve work efficiency when creating a production plan.

  Next, the flow of a processing procedure executed by the control unit 20 described above will be described using the flowcharts of FIGS. First, a procedure for creating process information from information input by a user and creating a load pile graph will be described with reference to FIG.

  When information related to the process is input by the user, the control unit 20 creates the process information 31D based on the input information through the process information creation unit 21 and stores it in the process information database 31 (step S11). Next, the control unit 20 reads the process information 31D stored in the process information database 31 through the seasonal process information creation unit 22, and determines whether or not the work period of the process information 31D extends over a plurality of seasons ( Step S12). When the work period spans a plurality of seasons (step S12: Yes), the process information 31D is divided into each season, and seasonal process information 32D for each season is created (step S13). Next, the control unit 20 assigns an index number to each seasonal process information 32D through the index number assigning unit 23, stores them in the seasonal process information database 32, and stores the index numbers in the seasonal process information set. It is added to the relevant seasonal process information aggregate in the body database 33 (step S15). On the other hand, in step S12, when the work period of the process information 31D does not extend over a plurality of seasons (step S12: No), the work period is not divided and the process information 31D is directly used as the seasonal process information 32D (step S14), assigning an index number to the seasonal process information 32D and storing it in the seasonal process information database 32, and storing the index number in the seasonal process information aggregate 33G corresponding to the seasonal process information aggregate database 33. It adds (step S15). Next, the control unit 20 determines whether there is process information 31D to be subsequently processed. When there is no process information 31D to be processed, that is, when the creation of the seasonal process information 32D of all the process information 31D is completed (step S16: Yes), the control unit 20 passes each total process through the total man-hour calculation unit 24. Read the information aggregate 33G. Then, by querying the seasonal process information database 32 for the used equipment and the man-hour corresponding to the index number stored in each seasonal process information aggregate 33G, the total man-hour of each season of each used equipment is calculated ( Step S17). Next, the control unit 20 creates a load pile graph for each equipment used based on the total man-hour calculated in step S17 through the graph creation unit 25 (step S18). The created load pile graph can be displayed on the display unit 12 or printed out on an output means (not shown) such as a printer in response to a user request.

  Next, FIG. 7 is a flowchart showing a flow of a processing procedure executed by the control unit 20 when a new process is added after the procedure shown in FIG. 6 is performed. Hereinafter, a process when a process is added will be described with reference to FIG.

  When information regarding the process to be added is input by the user, the control unit 20 creates additional process information 31D based on the input information through the process information creation unit 21 and stores it in the process information database 31 (step S21). Next, the control unit 20 determines whether or not the work period of the added process information 31D extends over a plurality of seasons through the seasonal process information creation unit 22 (step S22). When the work period extends over a plurality of seasons (step S22: Yes), the process information 31D is divided into each season, and the seasonal process information 32D for each season is created (step S23). Next, the control unit 20 assigns an index number to each seasonal process information 32D through the index number assigning unit 23, stores them in the seasonal process information database 32, and stores the index numbers in the seasonal process information set. In the body database 33, it is added to the relevant seasonal process information aggregate (step S25). On the other hand, in step S22, when the work period of the added process information 31D does not extend over a plurality of seasons (step S22: No), the work period is not divided and the process information 31D is directly used as seasonal process information 32D. (Step S24), an index number is assigned to the seasonal process information 32D and stored in the seasonal process information database 32, and the index number is stored in the seasonal process information aggregate database 33. (Step S25). Next, the control unit 20 determines whether there is process information 31D to be subsequently processed. When there is no process information 31D to be processed, that is, when creation of seasonal process information 32D of all the added process information 31D is completed (step S26: Yes), the control unit 20 passes through the total man-hour calculation unit 24. The seasonal process information aggregate 33G to which the added seasonal process information 32D belongs is read out. Then, by referring to the seasonal process information database 32 for the used equipment and the man-hour corresponding to the index number stored in the seasonal process information aggregate 33G, the total man-hours for each seasonal used equipment are recalculated. (Step S27). Next, the control unit 20 updates the load pile graph through the graph creation unit 25 based on the total man-hour calculated in step S27 (step S28).

  Next, FIG. 8 is a flowchart showing a flow of a processing procedure executed by the control unit 20 when the content of the process information stored in the process information database 31 is changed. Hereinafter, the process when the process information is changed will be described with reference to FIG.

  When the process information in the process information database 31 is read by the user and an input for changing the process start date and the process end date is made, the control unit 20 transmits the process information 31D through the process information creation unit 21. The process start date and the process end date are changed, and the contents of the process information 31D are updated (step S31). Next, the control unit 20 reads the changed process information 31D from the process information database 31 through the seasonal process information creation unit 22, and determines whether the work period of the process information 31D extends over a plurality of seasons ( Step S32). When the work period extends over a plurality of seasons (step S32: Yes), the process information 31D is divided into the seasons to create seasonal process information 32D for each season (step S33), and then the control unit 20 The index number assigning unit 23 assigns an index number to the created seasonal process information 32D and stores them in the seasonal process information database 32, and stores the index numbers in the seasonal process information aggregate database 33. Is added to the relevant seasonal process information aggregate (step S35). Then, the seasonal process information 32D and the index number before the change are deleted from the seasonal process information database 32 and the seasonal process information aggregate database 33 (step S36). On the other hand, when the work period does not extend over a plurality of seasons in step S32 (step S32: No), the work period is not divided and the process information 31D is used as the seasonal process information 32D as it is (step S34). . Next, the control unit 20 determines whether there is process information 31D to be subsequently processed. When there is no process information 31D to be processed, that is, when creation of seasonal process information 32D of all changed process information 31D is completed (step S37: Yes), the control unit 20 passes through the total man-hour calculation unit 24. The seasonal process information aggregate 33G to which the changed seasonal process information 32D belongs is read out. Then, by referring to the seasonal process information database 32 for the used equipment and the man-hour corresponding to the index number stored in the seasonal process information aggregate 33G, the total man-hours for each seasonal used equipment are recalculated. (Step S38). Next, the control unit 20 updates the load pile graph through the graph creation unit 25 based on the total man-hour calculated in step S38 (step S39).

  Next, an example of a display screen displayed on the display unit 20 by the screen display processing unit 26 of the control unit 20 will be described with reference to FIGS. 9 and 10. A display screen 40 shown in FIG. 9 is an example of a process plan editing / viewing screen for a user to edit or view process information input / addition / change.

  In the display screen 40, the upper part of the screen is the display area of the Gantt chart 41, the central part of the screen is the display area of the man-hour table 42, and the lower part of the screen is the display area of the load pile graph 43. The Gantt chart 41, the man-hour table 42, and the load pile graph 43 are displayed side by side on the same time axis as shown in FIG. Thus, by displaying the Gantt chart and the load pile graph side by side on the same time axis, the user can easily grasp the equipment and time exceeding the capacity in the factory. Further, in the display area of the load peak graph 43, the load peak graph 43 for each facility (two load peak graphs for the facilities A and B in FIG. 9) is displayed side by side on the same time axis. Thus, by displaying the load pile graph 43 for each facility side by side on the same time axis, it becomes easier for the user to examine the facility change.

  The display screen 40 has a graphical user interface (GUI) function. When a user operates a pointing device such as a mouse or a device such as a keyboard, an electric signal is transmitted from these input devices to the control unit 20. The data displayed on the display screen 40 can be changed.

  Hereinafter, an example of a procedure in which the user edits the data on the display screen 40 and an associated process of the control unit 20 will be described. As shown in FIG. 9, in the load peak graph 43 of the equipment B on the display screen 40, the load (total man-hours) in the middle of June 2009 greatly exceeds the production capacity line 44. On the other hand, in the load peak graph 43 of the facility B, the load at the beginning of June 2009 is significantly below the production capacity line 44 and there is a vacancy. For this reason, the user makes a plan to change the work period of the process number 12 of the Gantt chart 41. The process information of process number 12 before the change has a work period of mid-June 2009 and a man-hour of 100 hours. Hereinafter, a case where 50 hours out of 100 man-hours in the middle of June is changed to the beginning of June will be described.

  The user uses a mouse to move a cursor (not shown) on the display screen 40 onto the bar 45 of the process number 12 of the Gantt chart 41, and in this state, moves the bar 45 to a predetermined position in the early June column. Drag and drop to.

  This mouse operation by the user is transmitted to the control unit 20 as an electrical signal. When receiving the electrical signal from the mouse, the control unit 20 changes the bar 45 of the Gantt chart 41 on the display screen 40 to the position of the broken line 46 through the screen display processing unit 26. Further, the control unit 20 performs the process information change process (steps S32 to S39) of FIG. 8 and updates the load pile graph 43 of the display screen 40 through the screen display processing unit 26. That is, on the display screen 40, the man-hour of 50 hours is crushed (deleted) from the bar 47 in the middle of June in the load pile graph 43 of the equipment B, and the man-hour 50 is shown on the bar 48 in early June as indicated by the broken line 49. The amount of time will be piled up (added). Further, in the man-hour table 42, the man-hour in the middle of June 2009 of the process number 12 is changed from 100 to 50, and the man-hour in the early June 2009 is changed from 0 to 50.

  As described above, in the production plan creation system 1 according to the present embodiment, when the user drags the bar of the Gantt chart 41 to shift the work period, the load pile graph 43 is automatically crushed and piled up accordingly. It is configured to be performed. As described above, the data processing of the landslides and piles accompanying the change of the work period is read out from the seasonal process information aggregate 33G to be changed in the work period and stored in the read seasonal process information aggregate 33G. Only the seasonal process information 32D is processed. For this reason, compared with the case where the corresponding process information is extracted from the large amount of process information 31D stored in the process information database 31 and processed as in the conventional system, the processing speed of landslide / stacking is increased. be able to. As a result, it is possible to display the pile graph 43 after the change of the work period on the display screen 40 in a shorter time than conventional.

  In addition, in the production plan creation system 1 of the present embodiment, in addition to the change of the work period as described above, when the equipment used is changed, the equipment change of the pile graph 43 can be automatically performed accordingly. it can. As shown in FIG. 9, in the load peak graph 43 of the facility A on the display screen 40, the load (total man-hours) in the middle of July 2009 greatly exceeds the production capacity line 44. On the other hand, in the load peak graph 43 of the facility B, the load in the middle of July 2009 is significantly lower than the production capacity line 44 and there is an empty space. For this reason, the user makes a plan to change the equipment of the process number 14 of the Gantt chart 41 from A to B.

  Although illustration is omitted, on the display screen 40, the equipment column of each process of the Gantt chart 41 and the man-hour table 42 is configured as a menu icon, and the equipment list is displayed when the user clicks the equipment column of each process with the mouse. The desired equipment can be selected from the equipment list by pulling down. On the display screen 40, when changing the used equipment of the process number 14 from A to B, the user clicks the used equipment column 51 of the process number 14 of the Gantt chart 41 with the mouse, and the equipment is displayed from the displayed equipment list. By selecting B, the display in the used equipment column 51 is changed to equipment B. As a result, as shown in FIG. 9, the 50-hour man-hour of process number 14 is deleted from the bar 53 in the middle of July of the load peak graph 43 of the facility A, and the load peak graph 43 of the facility B in the middle of July. As indicated by the broken line 55, the man-hour for 50 hours is added to the bar 54. In addition, in the man-hour table 42, the used equipment column 52 of the process number 14 is changed from A to B.

  As described above, in the production plan creation system 1 according to the present embodiment, even when the user changes the equipment by clicking the equipment used column of each process in the Gantt chart 41, the load pile graph 43 is correspondingly changed. The equipment change is automatically performed, and the mountain graph 43 after the equipment change can be displayed on the display screen 40 in a shorter time than in the past.

  A display screen 60 shown in FIG. 10 displays Gantt charts and load pile graphs of a plurality of offices on one screen. In the display screen 60, the upper part of the screen is an area in which the Gantt charts 61 of a plurality of establishments are displayed in parallel, and the lower part of the screen is an area in which the load pile graphs 63 of the plurality of establishments are displayed in parallel. Yes. Similar to the display screen 40 shown in FIG. 9, the Gantt chart 61 and the load peak graph 63 are displayed side by side on the same time axis. The number inside the bar of the Gantt chart 61 represents the man-hour.

  Hereinafter, an example of a procedure in which the user edits the data on the display screen 60 and an associated process of the control unit 20 will be described. As shown in FIG. 10, in the load peak graph 63 of the facility A at the D office, the load (total man-hours) in early July 2009 greatly exceeds the production capacity line 64. On the other hand, in the load peak graph 63 of the facility A at the E office, the load in the beginning of July 2009 is significantly below the production capacity line 64 and there is a vacant state. For this reason, the user makes a plan to transfer the work of the process number 1 of the D office to the process in the early July of the E office.

  The user uses a mouse to move a cursor (not shown) on the display screen 60 onto the bar 65 of process number 1 in the Gantt chart 61 of the D office, and in this state, moves the bar 65 to the process of the E office. Drag and drop to number 1 mid-July.

  The operation of the mouse by the user is transmitted as an electrical signal to the control unit 20, and the same processing as the processing described in FIG. 9 is performed, so that the bar 65 of the Gantt chart 61 of the D office becomes the E office. To the position of the broken line 66 of the Gantt chart 61. Along with this, 100 hours of man-hours are crushed (deleted) from the bar 67 at the beginning of July in the load pile graph 63 of the D office, and a broken line appears on the bar 68 at the beginning of July in the load pile graph 63 of the E office. As indicated by 69, 100 man-hours are piled up (added).

  In this way, by displaying the Gantt chart and load pile graph of multiple manufacturing locations side by side on the same time axis, the user can grasp the process information of multiple manufacturing locations at a glance and cross production sites. It is possible to adjust the process progress and load.

  The production plan creation system 1 according to the above embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program can be distributed via a network such as the Internet. The program can also be executed by being recorded on a computer-readable recording medium such as a hard disk, a flexible disk (FD), a CD-ROM, an MO, and a DVD and being read from the recording medium by the computer.

  As explained above, the production plan creation system 1 according to the present embodiment stores the process information 31D including the process start date, the work end date, the used equipment, and the man-hour of each process input by the user. Seasonal process information in which the database 31 and the set production plan period are divided into unit periods (seasonal) having a predetermined time width, and the manhours of each process information 31D stored in the process information database 31 are divided every season. A seasonal process information creation unit 22 for creating 32D, and a seasonal process information aggregate database 33 for storing seasonal process information aggregates 33G in which seasonal process information 32D belonging to each season is aggregated. It is. In the conventional system, when a process load in a certain facility is crushed and piled up (change of work start date and work end date), the process information database 31 stores a large amount of process information. Since the corresponding process information 31D was extracted and processed, it took time to recalculate the pile. On the other hand, in the production plan creation system 1 according to the present embodiment, only the seasonal process information aggregate 33G of the season that is the target of mountain collapse and pile-up is read from the seasonal process information aggregate database 33, and the seasonal data read is read. What is necessary is just to process the seasonal process information 32D memorize | stored in the process information aggregate | assembly 33G, and can reduce the data amount processed compared with the past. As a result, it is possible to speed up the calculation of load piles and mountain breaks, and it is possible to improve work efficiency when creating a production plan.

In the above embodiment, in order to reduce the storage area (memory) of the seasonal process information aggregate 33, an index number is assigned to the seasonal process information 32D and the seasonal process information aggregate 33G has an index number. And only the seasonal information is stored. Then, when obtaining each season steps per use equipment accesses the season-specific process information database 32, using the information of the equipment and manpower corresponding to the index number stored in the season-specific process information aggregate 33G ₁ However, the present invention is not limited to this. That is, the seasonal process information 32D may be stored in the seasonal process information aggregate 33G. In this case, it is necessary to increase the storage area of the seasonal process information aggregate 33G, but the index number assignment process is not necessary.

  Moreover, in the said embodiment, it was set as the structure which provided both the seasonal process information database 32 which stores seasonal process information 32D, and the seasonal process information assembly database 33 which stores seasonal process information aggregate 33G. However, the configuration may be such that the seasonal process information database 32 is omitted. In this case, after creating the seasonal process information 32D from the process information 31D of the process information database 31, the seasonal process information 32D is directly stored in the relevant seasonal process information aggregate 33G.

  As described above, the production plan creation system and the production plan creation program according to the present invention are useful for creating a long-term production plan for a product produced through a number of processes, such as a large-scale device such as a turbine. .
