Description

  In the present invention, when the master data is maintained in the production management system, the product lead time is indicated by illustrating the part configuration, the production start / end date of each part, and the order / delivery date. The present invention relates to an information processing apparatus, an information processing method, and a program for supporting validity confirmation.

  In recent years, in the manufacturing industry, a manufacturing plan and a procurement plan for the product may be created by MRP (Material Requirements Planning). In order to realize the production quantity of the planned product, the quantity of parts to be ordered and the ordering time are determined from the necessary parts and inventory information in consideration of the parts delivery, processing and shipping plans.

  In general, a system called an MRP system or a production management system, a parts configuration table showing the relationship between the parts used in the product and the parent-child relationship between the parts, part configuration information called simply a parts list, and procurement, processing, and processing for each part. The master data such as time information (lead time) necessary for assembly is used to create MRP periodically or every day.

  Therefore, it is possible to manage from the viewpoint of whether the bill of materials and lead time are correctly registered in the master data, and whether the data itself, especially the lead time is appropriate, and there is no room for improvement. It becomes important.

  Conventionally, in order to verify the validity of the master data, an operation for illustrating the component configuration and the lead time using a Gantt chart has been performed. However, when there are hundreds of components, etc., it may take time (several days) to make an illustration, so it is necessary to give up the illustration for all items or to give up the validation itself. There were many. In such a case, verification was conducted by narrowing down to representative items.

  Also, test data is created, MRP is actually executed in a test environment, and evaluation is performed based on the result.

  However, execution of MRP is not only a preparation load but also a heavy load on the system. Furthermore, since the result is simply a list of numbers for which the start date and end date are calculated, the validity of the data cannot be determined intuitively. From such a reason, it is desirable to visualize it.

Therefore, the technique of Patent Document 1 has been proposed. This is based on the lead time of procurement, movement, processing, etc. of each part, and the graphic is changed for each status and each element is connected.

JP 2006-039712 A

  However, even if the technique of Patent Document 1 is used, in the case of a product having hundreds of parts or a product having a deep parent-child hierarchy, the parent-child relationship between the parts is simply connected and shown in the figure. It became difficult to confirm the parent-child relationship of the item to be noticed.

  In addition, if the production lead time and procurement lead time of the constituent items are long, the column will become very long, and if you use a personal computer etc., you can check the relationship of the lead time without scrolling the display screen left and right. First of all, it is troublesome for the user and it is difficult to confirm the parent-child relationship by scrolling. Or, even if it is printed and confirmed, it becomes a useless long form, which is not always convenient for the user.

  In addition, if spreadsheet software is used, the user has made settings to hide the display of parts other than the part of interest individually and arrange the appearance. However, it was a heavy work for the user.

  The present invention has been made to solve the above-described problems. From the parts table registered in the production management system and the lead time master data, the parent / child relationship and the lead time relationship are illustrated, and the parts table It is an object of the present invention to provide an apparatus for assisting in verifying the validity of master data.

It is possible to provide a device that performs the above.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing a configuration example of a lead time illustrating system according to an embodiment of the present invention. In FIG. 1, the illustrated system includes a host computer 101, a master data registration database 102, an operation terminal 103, and a printer 104, which are connected to each other via a network 105.

  FIG. 2 shows a hardware configuration of the operation terminal 103. In FIG. 2, the CPU 201 comprehensively controls each device and controller connected to the system bus 204.

  Further, the ROM 202 or the external memory 211 is necessary for realizing a BIOS (Basic Input / Output System) or an operating system program (hereinafter referred to as OS) that is a control program of the CPU 201 and functions executed by each server or each PC. Various programs to be described later are stored.

  The RAM 203 functions as a main memory, work area, and the like for the CPU 201. The CPU 201 implements various operations by loading a program necessary for execution of processing into the RAM 203 and executing the program.

  An input controller (input C) 205 controls input from a pointing device such as a keyboard 209 or a mouse (not shown). A video controller (VC) 206 controls display on a display device such as a CRT display (CRT) 210. The display device may be a liquid crystal display as well as a CRT. These are used by the administrator as needed.

  The present invention is not directly related. The memory controller (MC) 207 is a hard disk (HD), floppy (registered trademark) (FD) disk, or PCMCIA that stores a boot program, browser software, various application software, font data, user files, editing files, various data, and the like. Controls access to an external memory 211 such as a CompactFlash (registered trademark) memory connected to the card slot via an adapter. A communication I / F controller (communication I / FC) 208 is connected to and communicates with an external device via a network, and executes communication control processing in the network.

  For example, Internet communication using TCP / IP is possible. Note that the CPU 201 enables display on the CRT 210 by executing outline font rasterization processing on a display information area in the RAM 203, for example. In addition, the CPU 201 enables a user instruction with a mouse cursor (not shown) on the CRT 210.

  A program for realizing the present invention is recorded in the external memory 211 and is executed by the CPU 201 by being loaded into the RAM 202 as necessary.

  Furthermore, definition files and various information tables used by the program according to the present invention are stored in the external memory 211, and detailed descriptions thereof will be described later.

  Next, the host computer 101 has a hardware configuration almost the same as that of the operation terminal 103, and a description thereof will be omitted.

  Here, the external memory 211 has a database function. Here, a definition file and an information file necessary for operating the production management system are stored, and lead time master data used this time is also stored therein.

  FIG. 4 shows an example of a diagram for explaining a list of lead time master data.

  In FIG. 4, the lead time master data includes an expansion level 402, an item code 403, a procurement type 404, a production lead time 405, a procurement lead time 406, a shift days 407, and the like. These items are general production management systems. This item is not limited to this item.

  The expansion level 402 is an item showing the relationship between parts in a hierarchy. For example, focus on item 5. Since the expansion level is 2, the part which becomes the “parent” of the item 5 is the item 3 whose expansion level is 1. Conversely, a part that is a “child” of item 5 is item 6 with an expansion level of 3.

  In addition, the part which becomes the “parent” of the item 7 is the item 1 whose development level is 0. Thus, the parent-child relationship can be determined from the data of FIG.

  The item code 403 is a code for identifying a part, and the procurement type 404 is an item for distinguishing between a part manufactured in-house or a part purchased from the outside. The production lead time 405 is the number of days from the start to the end of production produced by the company. On the other hand, the procurement lead time is the number of days from ordering a part to be purchased from the outside to delivery.

  The number of shift days 407 is the number of days required before moving to the factory and before inspection after production or after delivery, and is the number of days for which the production end date and the delivery date are to be advanced.

  FIG. 3 is a module configuration diagram.

  In the present embodiment, description is given assuming that the operation is performed at the operation terminal 103 in consideration of operability, but the operation may be performed by the host computer 101. The operation terminal 103 includes a spreadsheet software 301, a macro module 302, a data input / output I / F 304, and a print driver 305.

  The data input / output I / F 304 inputs lead time master data from the database 102 of the host computer 101.

  The spreadsheet software 301 is realized by using general-purpose spreadsheet software having a macro function (for example, Excel (registered trademark) of Microsoft Corporation), but may be created exclusively. The macro module 302 is a program created in a dedicated language that operates on the spreadsheet software 301. The print driver 305 converts the data created by the spreadsheet software 301 into data for printing on the communicable printer 104.

  Next, an example of processing for illustrating the lead time will be described below with reference to a flowchart.

  FIG. 5 is a main flow for illustrating the lead time.

  Although details will be described later, in step S501, the lead time master data shown in FIG. 4 is downloaded from the database 102 to the operation terminal 101 and recorded in the external memory 211, and also on the spreadsheet of the spreadsheet software 301. Expand to. Next, after giving the WBS code to each line in step S502, the lead time is illustrated in step S503. Note that the WBS code is a code indicating a parent-child relationship between components, and is used as an object name in the figure generated by the lead time graphic processing.

  Next, the WBS code setting process in step S502 will be described below with reference to FIG.

  In step S 601, the development level of the lead time master data recorded in the external memory 211 is read for one row of data and stored in the RAM 203.

In step S602, the presence / absence of data is determined. If Yes, the process proceeds to step S603. If No, the process ends.

  In step S603, it is determined whether or not the development level is 0. If Yes, the process proceeds to step S604, where WBS code = 1 is input to the corresponding cell of the spreadsheet and stored in the external memory 211. Then, it returns to step S601 and repeats the process.

  On the other hand, if No in step S603, the process proceeds to step S605.

  If No in step S603, the process proceeds to step S605. If the expansion level of the row data currently stored in the RAM 203 is the same as the expansion level of the previous line data, the process proceeds to step S606, and the previous one The value obtained by adding 1 to the bottom layer of the WBS of the row data is WBS. For example, when the read development level is 1-1, the WBS code = 1-2 is input to the corresponding cell of the spreadsheet and stored in the external memory 211.

  If NO in step S605, the process proceeds to step S607, and it is determined whether or not the development level of the row data stored in the RAM 203 is higher than the development level of the previous row data. If YES, the process proceeds to step S608. Proceed, and add WSI to the end of the WBS of the previous row data (add "-1") and let WBS be the value. For example, when the read development level is 1, the WBS code = 1-1 is input to the corresponding cell of the spreadsheet and stored in the external memory 211.

  If No in step S607, the process proceeds to step S609, and it is determined whether or not the development level of the row data stored in the RAM 203 is smaller than the development level of the previous row data. If yes, the process proceeds to step S610. Then, from the WBS of the previous row data, the value up to the -1 layer from the currently read development level is acquired, and the value obtained by adding 1 to the -1 layer is set as the WBS. For example, if the previous WBS code = 1-2-3 and the read expansion level is 1, -3 in the third layer is deleted, 2 is added to 2 in the second layer, and WBS code = 1-3 Are input to the corresponding cell of the spreadsheet and stored in the external memory 211.

  Note that, in the case of No in step S609, since the data is NULL data or abnormal data, the process returns to step S601 without performing any processing.

When the WBS code is set up to the last line for the data stored in the external memory 211, the WBS code setting process ends.

  Next, the lead time plotting process in step S503 will be described below with reference to FIG.

  In step S 701, the read time master data recorded in the external memory 211 is read for one row of data and stored in the RAM 203.

  In step S702, the presence / absence of data is determined. If Yes, the process proceeds to step S703. If No, the process ends.

  In step S703, it is determined whether WBS is 1. If Yes, the process proceeds to step S704, and the required date indicating the production end date or delivery date is set as N days and stored in the RAM 203. Then, the process proceeds to step S707.

  In step S707, a day calculated by subtracting the number of shift days from the required date stored in the RAM 203 is calculated, and a figure is input as an end point mark in the left column by the number of shift days from the corresponding cell of the spreadsheet, that is, N. In this embodiment, “◯” is used as a starting point mark. sign up. The graphic object name at the time of graphic registration is “E” + “WBS” + “− X” + “number of lines” + “− Y” + “required date”. For example, when WBS is 1-2-2, the number of rows is 9, and the required date is N-14, the registered object name is E-1-2-2-X9-YN-14. This object name is information for identifying a component.

  In step S708, a date obtained by subtracting the shift days and the production lead time (procurement lead time) from the required date stored in the RAM 203 is calculated, and the figure is used as a starting point mark from the corresponding cell of the spreadsheet, that is, N. Enter the number of days in the left column. In this embodiment, “◯” is used as a starting point mark. The graphic object name at the time of graphic registration is “S” + “WBS” + “− X” + “number of lines” + “− Y” + “required date”. For example, when the WBS is 1-2-2, the number of rows is 9, and the required date is N-14, the registered object name is S-1-2-2-X9-YN-14.

  In step S709, the graphic object starting from “E-” input in step S707 and the graphic object starting from “S-” input in step S707 are visualized by connector connection in a form that can be visualized by a bar or the like. Illustrate and clarify relationships between objects. The object name when registering the connector is “L” + “WBS” + “− X” + “number of lines” + “− Y” + “required date” ”For example, WBS is 1-2-2 When the number of rows is 9 and the required date is N-14, the object name to be registered is L-1-2-2-X9-YN-14.

  In step S710, it is determined whether the WBS stored in the RAM 203 is 1. If Yes, the process proceeds to step S701 and the process is repeated. In No, it progresses to step S711.

  In step S711, the end point object starting from “E-” of the WBS stored in the RAM 203 and the start point object starting from “S-” of the development level one level above are connector-connected. The object name when registering the connector is “U” + “WBS” + “− X” + “number of lines” + “− Y” + “required date” ”For example, WBS is 1-2-2 When the number of rows is 9 and the required date is N-14, the object name to be registered is U-1-2-2-X9-YN-14 Next, the process returns to step S701 and the process is repeated.

  If No in step S703, the process proceeds to step S705.

  In step S705, it is determined whether the WBS hierarchy of the row data stored in the RAM 203 is the same as the WBS hierarchy of the previous row data stored in the RAM 203. The lead time of the current row data is set as the required date, and the process proceeds to step S707.

  Here, in the case of Yes, the process proceeds to step 706, and the required date is stored in the RAM 203 as the start point start date of the previous row data stored in the RAM 203. Then, the process proceeds to step S707 and the process is continued.

  When the process is repeated up to the last line data, the lead time plotting process ends. Thereby, for example, the parent-child relationship and the lead time relationship shown in FIG. 11 can be illustrated.

  In FIG. 11, the lead time master data 1101 of each component, the WBS code 1102 created by the WBS code setting process described in FIG. 6, and the lead time display unit 1103 illustrated by the lead time graphic process described in FIG. Are displayed side by side.

  Next, using the object name created in the process described with reference to FIG. 7, when the user confirms the parent-child relationship and the lead time, it is possible to clearly identify the component of interest and confirm it easily. An example of such an illustration process will be described below with reference to a flowchart.

  FIG. 8 is an example of a flowchart of a process for clarifying a parent-child relationship of a part to be watched from a large number of parts.

  The description of the parent-child explicit processing will be described below with reference to FIG. This process is activated when the operation menu 1201 of FIG. 12 is opened and the parent-child explicit button 1202 is pressed in a state where the graphic object of the part that the user wants to watch is selected.

  In step S801, the currently selected graphic object name is read from the object names created in the process described with reference to FIG. 7 stored in the RAM 203, and the WBS code portion is acquired from the read graphic object name. This acquired value is set as a reference WBS.

  In step S802, one graphic object name is read from graphic object names other than those stored in the RAM 203, and the WBS code portion is acquired from the read graphic object name.

  In step S803, the presence / absence of data is determined. If Yes, the process proceeds to step S804 to extract a graphic object having a parent-child relationship. If No, the process ends.

  In step S804, if the WBS code stored in the RAM 203 in step S802 is higher than the WBS code stored in the RAM 203 in step S801, the process proceeds to step S807. In cases other than that described here, process flow proceeds to Step S805.

  In step S805, if the WBS code stored in RAM 203 in step S802 is lower than the WBS code stored in RAM 203 in step S801, the process proceeds to step S807.

  In cases other than that described here, process flow proceeds to Step S806.

In step S806, if the WBS code stored in the RAM 203 in step S802 is the same as the WBS code stored in the RAM 203 in step S801, the process proceeds to step S807.

  In cases other than that described here, process flow proceeds to Step S808.

In step S807, the drawing information of the attribute of the graphic object currently being read is changed, the process proceeds to step S802, and the process is repeated. Here, as an example, the line thickness information of the drawing information is 6 points thicker than others, but this may be a line type or a color.

  In step S808, the drawing information of the attribute of the object currently being read is changed, the process proceeds to step S802, and the process is repeated. Similar to step 807, the line thickness information of the drawing information is reduced by one point here as an example, but this may be a line type or a color.

  In the embodiment, the line thickness information is increased in step S807 and the line is decreased in step S808. However, this is not limited to this as long as the user can distinguish, and in step S807. The line thickness information may be increased, and no processing may be performed in S808.

  In the embodiment, the case where one figure is selected has been described. However, when a plurality of figures are selected, the process from step S802 is performed for one figure, and when the process is completed, the next figure is renewed to step S802. It goes without saying that the processing from the above is repeated, and it is obvious that the user can easily make a judgment by changing the color of each of the drawing information of the attribute of the object when displaying. Furthermore, the display window may be changed.

  By performing such processing, for example, as shown in FIG. 13, the lead time display unit 1103 allows the user to select a graphic object of a part to be watched and confirm it with a simple operation while comparing it with others. Become.

  In addition, when a user described later selects a non-parent / child non-display process and receives an instruction for another process, a parent / child explicit cancellation process is performed. This parent-child explicit cancellation process makes the drawing information of the attributes of all the graphic objects the same. Here, as an example, it is assumed that processing for returning line thickness information to 1.5 points in the drawing information is performed.

  FIG. 9 is an example of a flowchart of non-parent / child non-display processing for displaying only a graphic object having a parent-child relationship of a part to be watched from among a large number of parts, that is, non-part other than a part having a parent-child relationship.

  The non-parent / child non-display process will be described below with reference to FIG. This process is activated when the operation menu 1201 in FIG. 12 is opened and the parent-child explicit button 1203 is pressed in a state in which the user selects the graphic object of the part that the user wants to watch.

  Steps S901 to S906 are the same as steps S801 to S806, respectively, and thus description thereof is omitted.

  In step S907, the drawing information of the attribute of the currently selected graphic object is changed to “no line”, the corresponding line is extracted from the position information of the graphic object, the line is hidden, and the process proceeds to step S322. Proceed and repeat the process.

  By performing such processing, for example, as shown in FIG. 14, the lead time display unit 1103 allows the user to select the graphic object of the part that the user wants to pay attention to, and with a simple operation, the parent-child relationship is not affected by other graphics. And lead time can be confirmed.

  When the user accepts an instruction for other processing, for example, by selecting the above-described parent-child explicit processing, the non-display cancellation processing is performed except for the parent-child. In the process of canceling the non-display other than the parent and child, all lines in which data exists are displayed again.

  In the embodiment, the case where one figure is selected has been described. However, when a plurality of figures are selected, the process from step S902 is performed for one figure, and when the process is completed, the next figure is renewed to step S902. It goes without saying that the processing from the above is repeated, and it is obvious that the user can easily make a judgment by changing the color of each of the drawing information of the attribute of the object when displaying. Furthermore, the display window may be changed.

  Next, with reference to the flowchart of FIG. 10, a blank column non-display process will be described with reference to a blank column non-display process in which, when the lead time becomes long, blank columns that are not relevant are hidden and displayed.

  Using the object name created in the process described in FIG. 7, the start / end period (not shown) specified by the user is accepted, and the blank column is selected from the specified period when the column non-display button is pressed. Hide and display wavy lines.

  FIG. 10 is a flowchart for explaining an embodiment of blank column non-display processing. This process is activated when the operation menu 1201 of FIG. 12 is opened and the blank column non-display button 1204 is pressed while FIG. 14 is displayed.

  In step S <b> 1001, a value input by the user on an input screen (not shown) for a reference date for hiding the column is acquired and stored in the RAM 203 as a non-display reference date.

  In step S <b> 1002, the column non-display process is executed, the start position is acquired from the input value from the screen, and the number of columns is stored in the RAM 203.

  In step S1003, column information of the number of columns stored in the RAM 203 is read.

  If the information read in step S1003 does not exist in step S1104, the process proceeds to step S1005. If information exists, the process proceeds to step S1008. In step S1008, line data information is read.

  If the read line is a non-displayed line in step S1009, the process proceeds to step S1010. In the case of a display line, the process proceeds to step S1016.

If the start point and the end point do not exist in the column read in step S1003 and the row read in step S1008 in step S1010, the process proceeds to step S1011. In cases other than that described here, process flow proceeds to Step S1016.

  In step S1011, it is determined whether the CNT that is the count value stored in the RAM 203 is smaller than the reference date stored in the RAM 203 in step S1001, and if it is smaller, the process proceeds to step S1012. In cases other than that described here, process flow proceeds to Step S1014.

  In step S1012, the columns from the currently processed column + 1 to the currently processed column + CNT stored in the RAM 203 are hidden.

  In step S1013, a column is additionally inserted after the column currently being processed, and a wavy figure is registered on the added column. The graphic object name at the time of graphic registration is “W −” + “column number”. For example, when the column is the 20th column, the registered object name is W-20. Next, step S1014 is performed.

  If the read line is the last line in step S1016, the process proceeds to step S1017. If not, the process returns to step S1008 and repeats the process.

  In step S1017, 1 is added to the CNT stored in the RAM 203, and the CNT is stored in the RAM 203 again.

  In step J1014, the CNT stored in the RAM 203 is changed to 0 and stored in the RAM 203 again.

  In step S1015, 1 is subtracted from the number of columns stored in the RAM 203, stored again in the RAM 203, and the process returns to step S1003.

  If it is determined in step S1005 that the CNT stored in the RAM 203 is greater than or equal to the non-display reference date stored in the RAM 203, the process proceeds to step S1006. Otherwise, the process ends.

  By performing such processing, for example, as shown in FIG. 15, the lead time display unit 1103 allows the user to select a graphic object of a part to be watched and perform a simple operation without affecting the other graphic. It becomes possible to easily confirm the parent-child relationship that is particularly important when confirming the above.
