  However, in these conventional techniques, the process or machine resource name, the execution period of the process and the occupation period of the machine resource are displayed with a bar, and only a Gantt chart for visually recognizing the process period is shown. In other words, the process management and the process progress were merely displayed on the Gantt chart with the production lead time (time axis) as a reference. On the other hand, in order to actually manage the production process, it is necessary to grasp the progress of each production process (equivalent to the production process for each facility) once production is started, and a plurality of equipment used in the production process. When manufacturing is performed in a context, there may be a need to change the plan in the process depending on the progress of the previous process in the process. Even if the Gantt chart showing the utilization period of equipment resources is simply displayed on the screen, the process is managed while referring to the various information behind it, even if it is necessary to refer to the plan and results sequentially for each production process. I couldn't.

  Also, in the case of multi-product process management that simultaneously processes multiple products when multiple products are combined to produce a single product, such as parts manufacturing and assembly, the conventional technology is similar. The production lead time is displayed as a bar on a single time axis. However, there are various long and short production lead times in process control even if the process is not limited to various types of processes. In the case of a process group (production process) that has a difference in production lead time, there are processes with a production lead time on a daily basis and production lead times on an hourly basis, and there are many production processes on a fixed time axis. The bar indicating the process of the product type cannot be displayed at an appropriate scale, and there is a limit to operability and visibility, such as a process for referring to information necessary for managing the production process on a separate screen. Yes, management efficiency and management accuracy had to be reduced.

  It is an object of the present invention to effectively display information associated with a production process, for example, conditions of equipment for performing a process, information for managing productivity, and information on required delivery date, and can be edited and changed. It is to provide a production management system including means. In particular, it is to realize a system that supports a series of responses from confirmation, analysis, evaluation, and correction of information related to a process in a production process management process.

  This management ensures product delivery within the delivery date (improves delivery time response capability), reduces costs by using the necessary amount of raw materials to reduce the impact on the environment, and reduces the manufacturing process. As a result, it is possible to support the improvement of the material balance accuracy (improvement of the material balance accuracy), the improvement of the quality, and the reduction of the man-hours.

  The present invention immediately displays productivity such as delivery time (delivery lead time), material balance, quality, work man-hours, etc., and issues alerts under certain conditions to promote corrective actions and improve productivity in the production process. To do. Furthermore, the present invention provides a display method and system for setting a time constraint (production lead time) reference for a process plan and selecting a process plan display format according to the setting. As a result, the time axis represents either a process plan in a vertical Gantt chart, a process plan in a horizontal Gantt chart, or a process plan in a table format. The process information input / output interface is displayed over the band display in the Gantt chart, or the band itself is used as the process information input / output interface, and the process information plan is reflected in the integrated database from the input / output interface. Make changes to the plan set in the interface. The result of the change is reflected in the integrated database, and the display form of the plan bar to be reviewed is changed by the change there. An instruction to switch to a display format outside the setting is also accepted.

  The present invention provides a versatile response capability by linking the production process plan and progress results input / output interfaces with various production process equipment conditions, productivity management standards, quality control standards, delivery date requirements, etc. as variables. The optimum display method selection logic to be realized is provided. As a result, the efficiency and accuracy of productivity management such as delivery date (delivery lead time), material balance, quality, and work man-hours for each process is improved, and corrective measures for the difference between the plan and progress are implemented accurately. Assures superiority in speed response capability, high quality provision capability, price competitiveness, etc., and contributes to profit improvement.

  Hereinafter, an embodiment of the present invention will be described in detail. Note that the present invention is not limited by this description.

  FIG. 1 is an overall configuration diagram of a system according to the present invention. The process plan progress performance productivity management apparatus 1 (hereinafter referred to as the process management apparatus 1) is realized by a general computer system including an input / output unit, a processing unit, a memory, and the like. The memory includes a multi-viewer management table 5 for storing information managed in the production process, and a multi-viewer for realizing a multi-viewer Gantt chart management system having the input / output interface (viewer) of the present invention. -Gantt chart management software 6 (hereinafter referred to as MVG management software 6), process plan information associated with the production process, progress result information, productivity management information, etc. are stored in an integrated database 7 in an integrated manner. . The Gantt chart created by the process management apparatus 1 is displayed in a display pattern determined according to the production lead time of the production process, as will be described later. The multi-viewer management table 5 holds a production lead time reference as a reference for selecting a display pattern of a production management process to be created. The integrated database 7 holds information for managing various processes managed by a multi-viewer Gantt chart management system (production process management system) in association with each other. For example, facility information indicating facility conditions used for the production process, productivity management information used for productivity management including yield, and production plan information including production process delivery date information are held. Details of the information stored in the integrated database 7 and the relationship between the information are shown in FIG.

  The process management apparatus 1 is connected to a plurality of clients 2 via a network 3. For example, a personal computer is used as the client 2 and is not only installed at the factory site where the production process is executed and managed in the production process, but can also be installed at an office managing the site for remote management.

  The operation of the multi-viewer Gantt chart management system will be described. FIG. 2 is a multi-viewer Gantt chart (hereinafter referred to as MVG) processing flow diagram of the present invention. Here, a web server is used for the process management apparatus 1, and a multi-viewer Gantt chart (MVG) 4 is sent to the client 2 while exchanging information with the MVG management table 5 and the integrated database 7 according to the processing of the MVG management software 6. indicate.

  The client 2 requests activation of the multi-viewer Gantt chart management system via the network 3. A transition request to the production process management screen is made by a screen call request operation from the menu of the client 2 (FIGS. 2 and 61). According to the basic function definition 65 in the MVG management software 6, the main screen operation and the search condition input part are displayed on the client 2 together with the search target information necessary for the search (FIGS. 2 and 62). At this time, information may be acquired from the integrated database 7 via the common interface structure 66.

  Next, a process plan group (production process) displayed in the search condition input unit is designated by a main screen operation of the client 2 (FIGS. 2 and 63), and the designation is sent to the process management apparatus 1 as a server. When this designation is received, the server produces the output associated with the process plan group designated via the DB access logic 68, which is the common interface structure, to the output logic (FIG. 2, 67) of the main screen function, which is the common function structure. Process information is acquired from the integrated database 7. The lead time of the target process plan is calculated using the acquired production process information (described later). Using the lead time of the calculation result and the lead time reference held in the MVG management table, the display format is automatically determined (described in FIG. 6), and the Gantt chart is displayed on the client 2 in a predetermined display format. Note that calculation of lead time and automatic determination of display format, which will be described later, are defined as a common function (FIGS. 2 and 69). For the common screen definition, the client 2 accesses the server via the network interface, and appropriately refers to the description of the common (screen definition 70).

  FIG. 3 shows a frame structure diagram of a multi-viewer Gantt chart (MVG) displayed on the client. The same number is assigned to the definition of the frame structure corresponding to the processing flow diagram of FIG. With these frame structure definitions, a screen according to the screen structure 77 is displayed on the client 2.

  FIG. 4 is an information relation diagram showing the information stored in the integrated database 7 regarding the production process together with the interrelationship between tables and information. This information relation diagram includes a process plan information section (XXX production plan plan table 81, XXX production plan table 82) indicating process plans, progress results, and productivity management information accompanying the production process, and progress management indicating progress result information. The table 83 indicates that other productivity management information is centrally managed. If the contents of the XXX production plan table 81 are confirmed, the contents of the XXX production plan table 82 are obtained, so that 81 and 82 have the same value after confirmation.

  Next, the calculation method of the lead time (LT) of the process plan and the determination of the display format of the MVG will be described with reference to FIGS. First, an input for designating a process plan is made from the client 2. The input screen is in the frame format of FIG. 5 and is in a state in which no data is input or not displayed in the area 51. As the designation input, items of business office, major category, middle category, minor category, and management process shown in 51 are entered. The values of the input items in FIG. 5 correspond to the values in FIG. When the search button 52 on the right side of the screen is instructed after the value is input to 51, process plan data having the same value as the input item (data of the management process KKK1 in this embodiment) is obtained from the integrated DB7. This processing is the processing of 61 and 62 in FIG.

  The lead time of the management process differs depending on whether the work of the management process is a batch input or a basic unit input, and which is the input is the LT setting in the “productivity management common” table in the information relation diagram of FIG. Determined by the symbol. If the LT setting symbol is “0”, the basic unit is input. If “1”, the work batch is input. If the work is batch input, the “LT fixed value (lead time fixed value)” in the data table relation diagram is used. In the case of inputting in basic unit, it is obtained by the calculation formula A × (X / Y) + B, and in the management process KKK1 of FIG. 4, A = 8, B = 32, X = 10,000, Y = 1,000. The lead time (LT) of the management process KKK1 is 112 hours (S10 in FIG. 6). In the information relation diagram, A is an LT coefficient, B is an LT fixed value, X is a work amount, and Y is a basic unit_amount.

  Next, using the management process code KKK1 as a key, the MVG management table 5 is read (S20 in FIG. 6), and LT reference data indicating setting criteria for the Gantt chart expression format of the management process is obtained. FIG. 7 shows items included in the MVG management table including the LT reference data.

  The MVG management table 5 includes items of “LT (long) criterion”, “LT (medium) criterion”, and “LT (short) criterion”. The display format of the Gantt chart is determined by comparing the values contained in these items of the MVG management table of the management process KKK1 with the lead time (eg, 112 hours) of the management process KKK1 calculated in FIG. 6S10 (FIG. 6S30). ). For example, if the “LT (long) criterion” is set to 100 hr or more, which is different from the numerical example of FIG. 7, the LT calculated in FIG. 6 S10 is 100 hr or more at 112 hr, and “LT (long) criterion” is set. Fulfill. Accordingly, the process proceeds to S40 in FIG. 6 and the vertical Gantt chart is edited as the display format. As shown in the numerical example of FIG. 7, if “LT (long) criterion” is 150 hr or more and “LT (medium) criterion” is 50 hr or more and less than 150 hr, LT = 112 hr calculated in FIG. Since the “LT (medium) standard” is satisfied, the process proceeds to S50 in FIG. 6 to edit the horizontal Gantt chart as the display format. In addition, if the “LT (long) criterion is 500 hr or more, the“ LT (medium) criterion ”is 150 hr or more and less than 500 hr, and the“ LT (short) criterion ”is less than 150 hr, which is different from the numerical example of FIG. For example, 112 hr calculated in FIG. 6S10 satisfies the “LT (short) criterion”, and the process proceeds to FIG. 6S60 where the table format is edited. When the display format is determined, the description of the common (screen definition) 70 in FIG. 2 is referred to, and the title part, the detailed list row title part on the horizontal axis, and the detailed list column title part on the vertical axis according to the predefined screen frame. Then, the Gantt chart or table editing result is selectively output to the display means of the client 2 by the arrangement of the detail list bar in the detail list body part (S70 in FIG. 6). The axis of the display area of the Gantt chart is a planned unit axis and a time unit axis arranged in units of used equipment. The plan unit axis is an axis that uses not only the equipment but also the items related to the production plan as a unit. For example, the plan unit axis may be a person in charge of the work, or may be a unit of parts produced by the production plan or a unit of assembly parts.

  Examples of multi-viewer output from the client 2 are shown in FIGS.

  FIG. 8 shows a display example of a vertical Gantt chart, in which the planning unit axis 10 representing the planning unit is taken as the horizontal axis, and the time unit axis 9 representing the planning time scale is taken as the vertical axis. A description will be given taking the column of the equipment S2 as an example. The display example of the column of the equipment S2 is a display example in which a process plan information part and a progress result information part representing a state where the results have been started are attached in a table format, and represents a display format after the start of the results. Reference numeral 13 denotes a plan bar (hatched portion) representing a process plan, and reference numeral 14 denotes an actual result bar displaying a progress result. Display bands such as the plan bar and the actual bar are called chart bars. The plan bar 13 and the performance bar 14 are displayed in an overlapping manner in the sense of contrast display. However, they may be displayed side by side as in the plan bar and the performance bar in the column of the equipment S3. In the display example of the column of the equipment S3, the plan bar and the result bar are arranged in parallel, and the process plan information part and the progress result information part are attached in tabular form on the bar, respectively. Returning to the column of the equipment S2, the upper sides of the plan bar 13 and the result bar 14 correspond to the planned start time and the actual start time of the process in the equipment S2. The lower side of the plan bar 13 corresponds to the plan end point. The lower side of the result bar 14 corresponds to the current time line (horizontal dotted line) if the process is actually in progress, and corresponds to the time when the process is completed. Note that the lower dotted line (the lower dotted line part of the area past the current time line) of the performance bar 14 indicates the end point (finishing date) according to a predetermined lead time from the actual process start point.

  Reference numeral 12 denotes an input / output interface displayed on the plan bar. The input / output interface 12 obtains and displays the corresponding process plan information and its performance information from the integrated database 7. Since the performance information also displays productivity information such as a defective rate, it is possible to grasp information relating to the production process visually with respect to time and other numerical information in association with the equipment. The input / output interface 12 displays the data in the integrated database 7 and directly changes the numerical values in 12 to reflect the data in the integrated database 7. Further, the input / output interface 12 superimposed on the plan bar may be the plan bar itself. Since the display area of the input / output interface 12 is limited to the band area of the plan bar 13, the input / output interface 12 is provided with a scroll display function to display the entire facility information, productivity management standard information, and delivery date information. You can also check and correct the output of information on the interface.

  The planning bar 13 also has an input / output interface function. By dragging the planning bar 13 in the time unit axis direction 15 with the mouse, the planning span (planning period), planning equipment, etc. are changed to reflect in the integrated database. it can. Furthermore, since the plan bar and the actual bar are displayed in comparison, it is easy to grasp the difference between the plan value and the actual value. For example, if the upper side of the plan bar 13 and the actual bar 14 match, it means that the process has started as planned, but the upper side does not match, that is, the upper side of the actual bar 14 is below the upper side of the plan bar 13. If so, there is a difference between the plan and the actual result. If this is left unattended, the lower side of the performance bar 14 is displayed behind the lower side (end setting time) of the plan bar 13. In this embodiment, the delay is grasped by the display relationship between the plan bar and the actual bar, and the measure for correcting the difference between the plan and the actual result by inputting to the input / output interface function of the plan bar 13 or the input / output interface 12 is taken. Take. For example, as the use of the input / output interface function of the plan bar 13, the plan end time (end set time) is changed by dragging the lower side of the plan bar 13 downward (in the time unit axis direction). This brings the plan closer to the actual result and eliminates the difference between the plan and the actual result. As another difference correction measure, when the facility information, the productivity management reference information, and the delivery date information are changed from the input / output interface 12, the scheduled end point of the plan bar is changed. The equipment information can be changed by changing the equipment for executing the process to another equipment. In order to change the productivity management standard information, it is conceivable to increase or decrease the yield according to recent results. Changing the delivery date information corresponds to directly changing the process completion scheduled date. In addition, it is possible to quickly eliminate the difference between the plan and the actual result, for example, by changing the planned amount of the equipment less than that of the input / output interface 12 and adjusting it so as to reach the end point as planned. In addition, when a difference correction measure is taken, the change is reflected in the integrated database 7. These difference corrective actions change the planned completion date of the planned process, but cause the need to review other processes of the same content that proceed in parallel with subsequent processes or changed processes. In order to encourage this review, change the display form, such as changing the color and tone of the plan bar of the post-process and related processes, or flashing, and alert the review of other processes on the client screen. In addition to visual alerting, an alarm sound may be output to alert the user to the review. The visual display change of the review bar is due to the display color and format in the detailed list bar generation definition file 75 of the common (screen definition) 70 being changed using the input to the input / output interface 12 as a trigger.

  The column of the equipment S1 in FIG. 8 is a column in which only the process plan information part is displayed on the plan bar, and represents a state where the results have not been started.

  The display format of the plan bar and the actual bar is defined in the common (screen definition) 70 as a multi-viewer Gantt chart frame structure, and the user selects a display format such as a plan bar and an actual bar superimposed type or a parallel type. Is possible.

  With this display format, necessary information related to production process management, which is suitable when the production lead time is (long), is displayed in a tabular format, improving operability and visibility and improving the efficiency of production management. Management accuracy can be improved.

  FIG. 9 shows a display layout diagram of a horizontal Gantt chart according to an embodiment of the present invention. Here, the spatial region based on the plan unit axis 10 representing the plan unit and the time unit axis 9 representing the plan time scale is the axis opposite to the display layout diagram of the vertical Gantt chart. In the present embodiment, the horizontal axis represents the date and shift (3 is the third shift, 1 is the first shift, and 2 is the second shift) related to time. In the vertical axis, a plan bar and an actual bar are arranged up and down in a frame representing a plan process, plan equipment, equipment conditions, and capacity related to the plan, and a dotted line in the space area represents a current time line. The result bar is expressed by a result part (hatched part) and a planned part (dotted line part). Progress result information, productivity information, and the like are displayed in the form of a table in the same manner as the vertical Gantt chart of FIG. In this embodiment, it is used as an initial display when the production lead time is (medium). An area surrounded by a dotted line on the plan bar 13 and the result bar 14 is an area corresponding to the input / output interface 12 of FIG. By displaying it in the vicinity of the bar, it is possible to instantly grasp that it is data for the plan visually, so that erroneous correspondence at the time of plan correction is reduced and quick response is possible.

  FIG. 10 is a tabular display layout diagram according to an embodiment of the present invention. This is a list of process plan information, progress results information and productivity management information in a tabular form based on product information such as product names, equipment, and manufacturing numbers common to process plan progress results productivity management. .

  In this embodiment, when the production lead time is (short), the table format of FIG. 10 is used as the initial display. This is a display format suitable for displaying a large amount of information on production processes in a tabular format.

  In addition, although the initial display format is set by the lead time for the vertical Gantt chart display, the horizontal Gantt chart display, and the table format display shown in FIGS. 8 to 10, the display formats can be switched between each other. For example, by right-clicking the mouse on the vertical Gantt chart of FIG. 8 and selecting and executing a display switching command to the prepared horizontal Gantt chart, the output logic 67 by function of the main screen of FIG. Definition) According to the structure definition file 71 of 70, the screen display is reconfigured into a horizontal Gantt chart.

  FIG. 5 is a display layout diagram of a vertical Gantt chart according to an embodiment of the present invention. In the screen structure, the upper part is a frame part (51, 52) for main operation and search condition input, a detailed list line title part (53) that is a horizontal axis of a plan unit in a spatial area of the Gantt chart, and a vertical unit of time unit. A detailed list column title part (54) is shown. The title portion corresponding to the origin of the space area displays information items on the horizontal axis. On the plan bar in the space area, the process plan / productivity information 55 is superimposed and displayed in a table format. This process plan / productivity information 55 corresponds to the input / output interface 12 in FIG. In the process plan / productivity information 55, it is possible to directly input the shipping date and the lot completion date. For example, when the lot work completion date of the process plan / productivity information 55 is delayed by one day and the classification is changed from normal to express, the display of the plan bar is also changed in accordance with the change, and the process plan / productivity information 55 Is also changed to 56. Specifically, as shown at 57, the plan bar extends to the lower side, that is, the position where the planned completion date is delayed by one day. This is because the change input data to the process plan / productivity information 55 is reflected in the integrated database 7, so that the bar display as the screen structure is changed by referring to the integrated database 7 changed in the common (screen definition) 70. Is due to being done. The process of reflecting the change in work completion date and the occurrence of delay days in the multi-viewer Gantt chart is a process after editing the multi-viewer Gantt chart, and corresponds to the process in FIG.

  In addition, in this embodiment, the scale of the time unit axis is applied as an option with the production lead time standard set to 7 days. If the display scale is set to “days” by setting the display scale of the main operation section at the top, production is possible. If the lead time is 1 week and the display scale is “week”, the time axis can be adjusted with the production lead time = January. Again, the dotted line in the space area represents the current time line.
