Description

[Detailed Description of the Invention] [Summary] Regarding a computer-assisted production information management method, production information such as manufacturing order, manufacturing method, and work result man-hours is integrated for the entire device or the entire factory, and it is possible to manage everything from design to manufacturing. Computer-aided production information management applied to factories that sequentially produce higher-level structural products by combining one or more structural products or parts, with the aim of enabling complete optimization. A system in which a structure or a structure that is a combination of parts is a parent structure, a structure or part one level below the parent structure is a structure specification, and child structures or parts for the parent structure are defined. For each parent structure, each table has an area for storing production information related to the production of the parent structure starting from the respective structure specifications. By searching for child structures that have a parent-child relationship with the specified structure in a chain using the structure's parent drawing number as a key, each of the searched child structures can be linked to the parent structure. It is configured to integrate production information stored in tables for structural products.

[Industrial application field]

TECHNICAL FIELD The present invention relates to a computer-assisted production information management method.

In recent years, CAD/CAM (computer-aided design and manufacturing) systems have been widely used in various industrial fields, and have greatly shortened product development periods by streamlining design and development operations, as well as saving labor in factories. Quality improvement,
This has had a significant effect on cost reduction. This CA
Further developing the D/CAM system as its core, CIM (CIM) integrates and manages production information for an entire factory or company.
A computer-integrated production system is in demand.

[Conventional technology]

To put it simply, devices manufactured (produced) in factories are aggregates of many parts and units, and have a hierarchical manufacturing system or structural system.

For example, in a factory that manufactures electronic devices such as communication equipment,
A printed board unit is manufactured by attaching a large number of parts to a printed circuit board, and a functional unit is manufactured by assembling several types of printed board units or a printed board unit with electronic parts and mechanical parts. Larger units are manufactured from the units (functional units), and these units are combined to manufacture electronic devices to be finally shipped.

In other words, multiple parts or structures (units) are assembled to form a structure (unit) at a higher level, and several types of structures or parts are assembled to form a structure at a higher level. By repeating this process, the final structural product (electronic device) is manufactured.

If the final structure is a device other than electronic equipment, such as a car,
Even if it is an electrical appliance or a unit building,
Even if the parts are not generally considered devices, such as electronic parts such as switches and capacitors, or other parts,
Although there are differences in the depth and expression of the hierarchy, as above,
Smaller parts are assembled to create larger parts and devices, resulting in the final product.

In this way, by combining one or more structures (child structures) or parts, higher-level structures (
In a factory that sequentially manufactures parent structural products, for each parent structural product there is a component list consisting of child structures and parts that make up the parent structural product.

Incidentally, the flow of production information in a factory is such that design information is created in a design department and transmitted to a manufacturing department, and the manufacturing department manufactures a device based on the design information. In the above example, the design department creates the component list, and the manufacturing department sequentially assembles parts and child structures based on the component list.

Now, according to the CAD/CAM system, production preparations are carried out in the manufacturing department based on design information created in the design department, but conventionally, information regarding the manufacturing process or the flow of the manufacturing process is handled by the manufacturing department. It is often created manually by a person.

For example, even if the above-mentioned list of components is created in the design department, the manufacturing order and manufacturing method for each structural item are created for each manufacturing process of each structural item in a specialized manufacturing department. . In addition, the actual number of man-hours required for manufacturing is compiled based on the unique data of each department that requires such aggregation, such as a department that tallies costs or a department that makes estimates.

[Problem to be solved by the invention]

Therefore, it is not easy to aggregate production information such as the manufacturing order, manufacturing method, and actual man-hours of work for structural products such as equipment and units for the entire equipment or to manage the entire factory, especially in the manufacturing department. Creating and managing production information requires a lot of time and effort.

In other words, conventional CAD/CAM systems are segmented into areas of design and manufacturing, and many parts are operated independently for each business or specialty. The situation is extremely inadequate.

In view of the above-mentioned problems, the present invention aims to integrate production information such as manufacturing order, manufacturing method, and actual work man-hours for the entire device or the entire factory, thereby making it possible to optimize everything from design to manufacturing. The purpose is

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention, as shown in FIG. In this production information management method, a structural product or a structural product that is a combination of parts is defined as a parent structural product 32, and lower-level structural products or components that make up the parent structural product 32 are defined as structural product specifications STY. Each parent structure 32 has a table 31 containing a child product or component list 33 for the product 32, and each table 31 includes the parent product list 33 starting from the respective structure product specification SIY. An area is provided to store production information 34, 35 related to the production of the structural product 32, and using the parent drawing number OZU of the structure as a key, a child manufactured product that has a parent-child relationship with the specified structural product 32 is created. By searching in a chain, the production information 34 and 35 stored in the table 31 with each of the searched child products as the parent structure product is integrated.

[For production]

The table 31 includes a parent structure 32, a list 33 of structure specifications 1isTY for this parent structure 32, and a list 33 of the structure specifications 1isTY for this parent structure 32.
The parent structure product 3 started from each child product in 3.
Production information 34 and 35 related to the production of No. 2 is stored.

When the parent structural item 32 is specified and a search is made for a structural item that has a parent-child relationship, tree structure data in which structural items are hierarchically linked is obtained. The production information 34 and 35 stored in each table 31 are related to each other by this tree structure data, and the production information 34 can be displayed in whole or in part by the tree structure, or by aggregating related parts. It is used as appropriate depending on the type of ゜35.

In other words, multiple parts and units (structural items) are assembled together to form a higher-level unit.
Furthermore, several types of units or parts are assembled to form a unit at a higher level, and by repeating this process, an electronic device is finally manufactured. The unit is
In most cases, the parts are assembled in the factory, but in some cases, the assembled parts are purchased as purchased items.0 parts are single purchased items, except for special items.

Now, the production information management system S includes a CPU (central processing unit) 11 having a main storage device 12, a drawing number file 13 stored in an external storage device, a related drawing number file 14, a parent-child drawing number file 15, and a drawing file. 16, work file 17, and tablet 20. It is composed of a keyboard 21, a display section 22, a printer 23, and a communication control device 24 for connecting to an external device 25, a terminal device 26, and the like.

The drawing number file 13 is a file that stores all drawing numbers in which the fourth digit of the drawing number is rB among the drawings used in the factory. Drawings with "B" in the fourth digit of the figure number are Structure 8 Table 31 (see FIG. 1), and the drawing numbers in Structure 8 Table 31 are representative drawing numbers among the many drawing types.

In other words, as shown in Figure 1, the drawing number consists of three blocks of four digits, totaling 12 digits, and the fourth digit represents the drawing type, and the drawing number consists of 9 digits. The English letters in the eye represent the level of composition of the drawing.

For example, the drawing type is 'AJ' for specifications, 'B' for 8 configuration tables,
I'CJ created the circuit diagram and block diagram, "DJ created the implementation diagram,"
``E'' is a wiring diagram, ``G'' is a wiring table, ``K'' is a time chart, ``N'' is a test specification, etc., and some drawings are present and some are not, depending on the type of unit. Composition 8 Table 31 of "B" shows what kind of things (child products or parts) the unit covered by the drawing is composed of, as well as production information such as the manufacturing method and number of man-hours for the unit. , and is a drawing representative of the drawings related to that unit. The configuration 8 table 31 will be explained in detail later.

Each record in the drawing number file 13 has items such as drawing number, version number, design opening, and name.

The related drawing number file 14 includes the above-mentioned structure 8 table 31 in drawings related to one component such as each unit.
This is a file that stores all drawing numbers except . Using the related figure number file 14, figure numbers of other drawing types (related figure numbers) related to the configuration 8 table 31 of a certain unit can be searched.

The parent-child figure number file 15 is a file that stores the parent figure numbers OZU of a large number of configuration 8 tables 31 and the parent figure numbers OZU of the configuration 8 tables 31 that are one level lower than the parent figure numbers OZU as a table of parent-child relationships. .

FIG. 1 is a diagram showing the structure of a structure 8 table 31 according to the present invention.

The configuration 8 table 31 shows the component list 3 with the parent structure 32 displayed by the name MAY and the parent drawing number OZU as the heading.
3, manufacturing method data 34, and man-hour data 35.

The component list 33 includes the product name HI for each one-level lower unit or component that constitutes the parent structural product 32.
N, specification 11isIY, number of pieces used KO3, and notes B
IK has been written.

The item ``AsIY'' indicates that it is a unit such as a printed board unit or other complex, and it is listed in Table 31 of Table 8.
If there is, the figure number in Table 8 of the configuration of that unit is

The figure number written in the specification SIY is a child figure number to the parent figure number OZU.

Therefore, for the unit with the child drawing number, there is a configuration table 31 different from that in FIG. 1 in which the unit is the parent structure 32. Furthermore, the unit written in the parent structure 32 is a child structure whose parent structure is the unit at the -level higher than the unit, and therefore the unit written in the parent structure 32 is written in the component list 33. Another configuration 8
Table 31 exists. In other words, for all structural items such as devices and units other than parts and purchased items, there is a configuration table 31 in which the parent structural item 32 is the structural item.

Next, the manufacturing method data 34 is written in which the manufacturing steps for manufacturing the device or unit shown in the parent structure 32 are written from top to bottom in the order of the steps, and the process KOU is the name of the process. , the screen name ZUM, which is the name of the drawing required for each process, the distribution IAI, which shows the distribution destination and number of concave sheets in code, and the jig or testing machine required for each process, which shows the code. There is an item for the tool testing machine ZIG.

The man-hour data 35 is such that the man-hours of each process KOU shown in the manufacturing method data 34 are written in the respective items of estimated M I T, previous actual JIS, and average HEI.

The estimate MIT is written when there is no manufacturing record for the parent structure product 32. The previous performance JIS is written after the manufacturing of the parent structural product 32 is completed, and if there is data written before then, it is rewritten by this. The average value of past actual man-hours is automatically calculated and written in the average HEI.

Among these data, parent structure product 32 and component list 3
3 is timely inputted by a design engineer in the design department, manufacturing method data 34 by a manufacturing engineer in the manufacturing department, and man-hour data 35 by a person in charge of the manufacturing department from the terminal device 26 installed in each department. be done.

The configuration 8 table 31 shown in FIG. 1 shows the name MA of the parent structure product 32.

``, rAFC circuit (2)'', two resistors, five lamps, and a chassis.

The "rAFC circuit" is manufactured through the steps of assembly, wiring, biopsy (intermediate inspection), and testing, as shown in the manufacturing method data 34.

Also, the actual man-hours when the previous loft was manufactured were 0°5.0.6.0.2.0 in each process.
It is 2 hours.

This rAFC circuit is one of the units incorporated as a component of the receiver of the ground radar equipment.
These relationships are shown in FIG. 2 as a configuration table 41. This will be discussed later.

The drawing file 16 stores data regarding a large number of drawings such as circuit diagrams and wiring diagrams created by design engineers using the tablet 20, keyboard 21, and the like.

The work file 17 is a file that stores data processed and created by the CPU 11 based on data stored in other files or data sent from the external device 25 or the terminal device 26. Data such as a configuration table 41 and a manufacturing process flowchart 51, which will be described later, are stored.

The display section 22 uses a cathode ray tube or the like to
It is configured so that graphic data and character data output from the computer can be displayed in color.

The printer 23 prints the output from the CPUI 1 and prints out a configuration table 41 and a manufacturing process flowchart 51, which will be described later.
, and for issuing various other lists and forms.

The external device 25 supports the processing functions of the CPU 1 and the terminal device 26 as a CAD/CAM system.

In addition, the external device 25 operates a drawing management system, a process management system, etc., and the external device 25 and CPU
1, data is transferred and stored as necessary.

A large number of terminal devices 26 are installed in the design department, manufacturing department, and other departments, and are used as a normal CAD/CAM system. 41 and a manufacturing process flowchart 51.

The CPU II uses the parent drawing number OZU specified by input from the keyboard 21 as a key, and executes the parent drawing number OZU.
The figure numbers that have a parent-child relationship with U are searched in a chain manner using the component list 33 stored in the configuration table 31 of the parent-child figure number file 15, and a tree of components with the designated parent figure number OZU as the vertex is created. The structure table 41 (see Figure 2), which is structural data, is created and stored in the work file 17, and the tree structure data associated with the structure table 41 is used to create the structure data stored in each structure table 31. The manufacturing process flowchart 51 (see FIG. 3) is created by integrating the manufacturing method data 34 and stored in the work file 17. Further, in response to a command, the man-hour data 35 stored in the configuration 8 table 31 is integrated and totaled using the above-mentioned tree structure data. The CPU 11 performs other necessary processing and also controls the display section 22, communication control device 24, and the like.

Next, a production information management method by the production information management system S mentioned above will be explained with reference to the flowchart shown in FIG.

First, the design department uses the tablet 20, keyboard 21, display unit 22, etc.
Operate as a D/CAM system and design or change the design (step #1).

The data generated thereby is stored in the drawing file 16.

As part of the design work, a component list 33 in a configuration table 31 is created for each regulation product 32 (step #2).

Then, necessary data is written into the manufacturing method data 34 of the configuration 8 table 31 (step #3), and the configuration 8 table 31 with the data written therein is converted into a database.

At the time when all of the tree-structured configurations such as devices 8 tables 31 have been created as a database, it is possible to
By instructing II, the configuration table 41 shown in FIG. 2 can be printed by the printer 23.

The configuration table 41 shown in FIG. 2 hierarchically shows some of the structural items constituting the "ground radar device" using a tree structure. In other words, the "ground radar device" is set as the top-level regulatory product, and the child products at the -level lower are shown in a tree structure in a chain.

In the configuration table 41 in FIG. 2, ruled lines LA and LB.

LC...'s horizontal position indicates the level of the hierarchy, and is level A, level B, level C, and so on, respectively.
...represents... The square symbol Q marked at the position of each level indicates that the unit or part with the name and drawing number written on the right side is located at that level.0For example, "ground radar equipment" is at level A. Yes, the "transmitter/receiver" is level B and is a descendant of the "ground radar device." In addition, the "receiver" is level D, and its descendant products include "Buri IF amplifier", "rlf log amplifier",
rAFC circuit" and "front end," both of which are level E. The depth of the tree structure is 7 levels, and items that can be placed at the lowest level consist of parts, purchased items, etc., and are structural items that cannot be made into a tree structure any further.

On the right side of the figure number, the fourth digit English symbol of all related figure numbers, each of which is a representative figure number, is written.

Composition table 41 systematically represents all the names of the structures constituting the "ground radar device", the drawing numbers in Table 31 of the configuration 8, and their related drawing numbers, and allows for the production of the "ground radar device". You can easily find out all the units and parts necessary for this, as well as all the drawings that exist for that purpose. In addition, one unit constituting the "ground radar equipment", for example rA
It is also easy to know what kind of units and parts the FC circuit is made up of.

In this case, the "rAFC circuit" is designated as a regulation manufactured product,
rAFC circuit” as the highest level tree structure Table 41
You can also create . Note that the configuration table 41, the configuration table 31, the manufacturing process flowchart 51, which will be described later, and the like can also be displayed on the display unit 22.

In addition, drawings necessary for manufacturing and manufacturing process flowchart 51
, and other documents are printed by the printer 23 or the printer installed in the terminal device 26 (step #4). When the work process at each process site is completed, data to that effect is input from the terminal device 26, so the drawings necessary for the next process are printed at that timing, and the printed drawings are distributed to the process site by the person in charge, for example. be done. Manufacturing process flowchart 51
is created in the same manner as the configuration table 41 described above.

FIG. 3 is a diagram showing a manufacturing process flowchart 51.

This manufacturing process flowchart 51 integrates the manufacturing method data 34 stored in each configuration 8 table 31 using the tree structure data associated with the configuration table 41, and integrates the manufacturing method data 34 stored in each configuration 8 table 31. The necessary manufacturing processes are hierarchically shown in a tree structure.

In the manufacturing process flowchart 51 of FIG. 3, an inverted triangular symbol T indicates a structural product, and above it, the name and figure number of the structural product are written in correspondence with the above-mentioned construction table 41. Assuming that an inverted triangle symbol T indicates a parent structure, an inverted triangle symbol T that connects from the right side to a vertical line extending downward from that inverted triangle symbol T,
It shows its offspring.

A circle or diamond-shaped symbol drawn in the middle of a vertical line extending downward from the inverted triangle symbol T represents a process necessary for manufacturing a parent structure using a child structure. In other words, by performing the process drawn along the vertical line on the child structure connected from the right side of the vertical line, the parent structure drawn directly above the vertical line is manufactured. It will be done.

For example, the parent structure ``rAFC circuit'' has the component parts ``rAFC circuit (1)'', ``rAFC circuit (2)'', the child parts ``rAFC circuit (1)'', ``rAFC circuit (2)'', and the second component ``rAFC circuit'', and the assembly process, wiring process, intermediate The inspection process and the test process are completed by performing them in this order.

Units are manufactured or tested in each process according to the above manufacturing process flowchart 51 or the documents and drawings distributed to each process (step #5).

Thereafter, from the terminal device 26 installed in the manufacturing department, the actual man-hours required in each process are input into the previous actual JIS of the man-hour data 35 of the configuration 8 table 31 (step #6).

Keyboard 21 and terminal bag! 26 etc., the data written in the man-hour data 35 can be integrated and aggregated using the above-mentioned tree structure data, and the results are provided to the appropriate department, thereby providing production information such as actual man-hours. Feedback to each department (Step #7)
.

In addition, in this production information management system S, since a large number of devices and the like are stored in the parent-child file 15, it is also possible to search for all parent structures that have a part such as a unit as a child product, or to search for that parent structure. A chain search is performed for parent structures to be used as child products, and the results can be displayed on the display section 22 or printed by the printer 23. With this, when the specifications of one unit or part are changed, it is possible to know which units or devices are directly or indirectly affected by the change.

According to the embodiment described above, the data written in the manufacturing method data 34 and man-hour data 35 areas provided in the configuration 8 table 31 are integrated by the search function using the component list 33.

This makes it possible to create a manufacturing process flowchart 51, listing all the processes up to manufacturing a specified unit or device, as well as necessary drawings, jigs, testing machines, etc. You can find out what level or process requires detailed drawings, jigs, or testing machines.

In addition, the total number of man-hours required to manufacture the device can be accurately and easily estimated based on past results.
It is possible to accurately predict the construction period. The drawings needed at each process site can be printed and distributed at the required time. When changing the design of a unit or part, you can know what kind of impact it will have on the equipment, other units, or the manufacturing process, allowing you to optimize the design and make changes to the actual design. When a design change is made, it is possible to easily check the affected units.

In other words, the manufacturing method data 34 of each configuration 8 Table 31
The data written in the and man-hour data 35 are associated with each other and integrated by the parent-child relationship of the component list 33, and based on these data, the design, manufacturing, and
Information necessary for management and management can be easily and automatically created, and design, manufacturing, and information processing can be optimized.

Therefore, the labor required to create this information in the past can be eliminated or significantly reduced, and the overhead costs can be significantly reduced.

In the above embodiment, the data written in the manufacturing method data 34 and man-hour data 35 as production information was explained, but in addition, the unit price of units and parts, material cost, manufacturing cost, inventory status, delivery date, process progress. Write down information such as the situation, standard man-hours required for each process, historical information, defective data, or data regarding reliability and quality.
These may be managed in an integrated manner.

In the above embodiment, the number of each unit or part, notes, man-hour data, etc. may be displayed next to the drawing number in the configuration table 41. , for example, is displayed only when the fourth digit of the drawing number is r13J and the ninth digit is "T" indicating a list of component parts, and is a mechanical part manufactured by mechanically assembling multiple mechanical parts. Since there is a "chassis"
Instead of displaying, for example, "mechanism assembly" is displayed, and next to it, the figure number of the mechanical parts list containing the parts list for assembling the "chassis" is displayed. 1. Enter the tree structure system of mechanical parts. Names, drawing numbers, codes, and other symbols may be used to represent visibility objects and child objects for guidance.

In the above embodiment, an example was shown in which the production information management system S was applied to a factory that manufactures electronic devices, but it can also be applied to factories that manufacture other devices such as automobiles, electrical appliances, or unit buildings. be able to. In addition, sales information can be added to design information and manufacturing information, and this information can be integrated to streamline these operations and be used for strategic management of a company.
