  In S403, the processing in S404 to S409 is repeated for the number of remaining work items extracted.

  In S404, it is determined whether the remaining work item is the work instruction (210f) “target”. If it is “excluded”, the process proceeds to S408. If it is “target”, S405 is performed.

In S405 judges, warehousing date when 210c of work progress information 210 whether or not it is part supply, from the supply date when the 210d. If the parts can be supplied, the process proceeds to S406 as it is. If the parts cannot be supplied, the work instruction is set to “excluded” in S407.

  In step S406, the parent part 220c is specified from the work information 220, and it is determined whether the parent part can be supplied. If there is a parent part, the process returns to the repetition processing of S403. If there is no parent part (cannot be supplied), the work instruction is set to “exclude” in S407.

  In S <b> 408, structurally related component information (related component 220 e) is acquired from the work information 220, and the presence or absence of the related component is determined. If there is a related part, the work instruction relating to the related part is set to “excluded” in S409. If there is no related part, the process returns to S403 iteration.

  In S410, the item in which “exclusion” is input in the work instruction (210f) is extracted from the work progress information 210, and the part of the work instruction (220f) “exclusion” is maintained while maintaining the original work instruction order 220f relationship. Is inserted at the end of the work order of the part of the work instruction “target”.

The delay recovery priority order 610e is determined in descending order of the days of delay in the work progress status 610d.
(Step 510) The work qualification of the worker (supporter) of the product whose work is stagnant is acquired from the work qualification information.
(Step 520) The product having a high degree of delay is determined and given a priority.
(Step 530) N = 1, that is, priority No. Perform initial settings for.
(Step 540) With respect to the N-th priority product, work qualification information necessary for work not yet started is acquired from the work information.
(Step 550) It is determined whether a supporter can work on a product with a high priority.
(Step 551) It is determined whether there are other support candidate products.
(Step 552) In order to determine the next priority product, N = N + 1.
(Step 553) It is determined that there is no support destination.
(Step 560) From the unstarted work of the product, a new work instruction is created by assigning to the supporter the work in the second hierarchy or lower as shown in FIG.

  FIG. 14 is an explanatory diagram showing parts and work order of a product to be numbered, and showing a group configuration (a group and its part hierarchy) in a parent-child hierarchy.

  In the definition of the hierarchy, the part that is directly assembled to the base part (the first part to be placed) is set as the first hierarchy part. For a part having a child part under the first layer, the child part is set as the second layer. Furthermore, if there are grandchild parts, the hierarchy of the grandchild parts is set as the third hierarchy. The parts of the second and third layers are parts that can be worked at a place different from the assembly work of the first layer, and indicate that time and space can be divided. In other words, the hierarchy is a measure of work division.

  The hierarchy will be described below using the FAN unit as an example.

First layer [5] FAN unit Second layer [5-1] Unit case [5-2] Card [5-3] PI-Assy
3rd layer [5-3-1] PI
[5-3-2] PI case
Second layer [5-4] FUSE
[5-5] Electric wire
[5-6] Electric wire

  FIG. 16 is a list of work status information based on the worker, and shows the current work status for each worker and the next work for each worker. The current work status is acquired from the work progress information 210 stored in the work progress information storage unit 105, and the next work is determined by the work instruction recalculation process in FIG. And

  Through the above processing, if the work in one work cell becomes stagnant for some reason in cell production in which manufacturing work for another product is performed in parallel in multiple work cells, the worker in that work cell It is possible to newly recalculate and provide a work instruction for supporting the work to the cell.

(Determining the parent-child relationship of parts)
In S406 of the processing flow S400 shown in FIG. 9, the determination of the parent-child relationship of the parts (parent part 220c and child part 220d shown in FIG. 3) and the method thereof will be described using a specific example.

  The items of the parent part 220c, the child part 220d, and the related part 220e of the work information 220 indicate the structural relationship of each part in the product assembly process, and will be described with reference to FIG. However, in this example, the three-dimensional model is shown as a two-dimensional model for simplification of explanation.

  The definition of the parent part 220c and the child part 220d is that when a certain part B is attached, if the attachment operation cannot be performed without the part A, the part A is the parent part of the part B and the part B is the child part of the part A. . At this time, the determination of the parent part and the child part is a three-dimensional model design system. In the three-dimensional model composed of at least two or more part models, at least one surface is structurally adjacent or matched. A thing is extracted, and a parent part and a child part of each part in the above definition are determined from the structural relationship. The details of each part are held in the drawing data managed by the drawing number 230d of the part warehousing information 230.

  Taking the part D in FIG. 10 as an example, the parent parts of the part D are the parts C and B, and the child parts of the part D are the parts E.

  Next, the concept of related parts will be described with reference to FIG. Set the mounting surface as shown by the shaded part in the figure, and consider the rectangular parallelepiped and component mounting space as shown by the broken line with the component mounting surface as the bottom, and the components included in this rectangular parallelepiped Related parts. At this time, the dimension of the bottom surface of the component is set to be larger than the maximum width of the component so that the component can be completely covered. For example, to explain using the XYZ coordinates shown in the figure, a rectangular parallelepiped in the X direction (part maximum width + 5 cm), the Y direction (part maximum width + 4 cm), and the Z direction (part maximum width + 20 cm) is considered. When a part is included in the rectangular parallelepiped and is not structurally adjacent, the part is determined to be a related part.

  The related parts will be described by taking the part D in FIG. 10 as an example. The related parts included in the part mounting space indicated by the broken line are the part F, the part G, the part H, and the part I.

  As mentioned above, if either the parent part or the child part does not arrive, or if there is a problem with the quality of one of the parent part or the child part, it will affect the progress of the work related to the other. Stagnation occurs. Also, as shown in FIG. 10, when the parent parts of the part D are the parts C and B and the child parts of the part D are the parts E, the parts B, C, the parts D, and the parts E are the parent parts. -There is a child-grandchild relationship, and the same problem may occur with the parent-grandchild relationship, in which case work stagnation will occur.
