MODELING AND VERFICATION OF PRODUCT DESIGN PROCESS

As a precondition, in the detailed design stage of a product design, the curtain wall materials are divided per
module materials based on "Design BOM", and the "materials library" is created. The "Design BOM" creates
the structure which can respond to two or more product kinds and option materials flexibly by dividing to the
module materials of curtain wall materials and changing those module materials into a "materials library".

Next, at the stage when considering of assembling sequence, the "Manufacturing BOM" is created. Moreover, in
order to create "Manufacturing BOM" from the "materials module" stored in this materials library, it is necessary
to determine the assembly method and an assembly order about the materials. Below, the procedure of operating
process modeling of a production design stage is describes: 1) modeling "Design BOM" upon the part drawing of
the detailed design stage of a product design, 2) modeling "materials library" out of module materials based on the
part information on Design BOM, and 3) modeling "Manufacturing BOM" based on the materials library. The
validity of the process data of each product design stage is verified by 3D-CG digital mock-up simulation, and the
basic data of the verified Manufacturing BOM as a "final deliverables".

MODELING AND VERIFICATION OF DESIGN PROCESS FOR PRODUCTION SYSTEM

According to a construction project, it is necessary to deliver required materials, tools, machines, etc. in the
construction process of a curtain wall to the working area or a destination. Moreover, according to a construction
schedule, it is necessary to assemble the delivered materials, carrying out suitable work organization. The
following procedures perform such a construction process as modeling of the production system design by using
the PE tool: 1) the routing planning of materials assembly work, 2) process organization of the materials assembly
work by two or more work contractors, 3) the resources planning for a delivery process, and 4) the site resource
planning of the construction place corresponding to integration between the assembly work and the resource
delivery process just-in-time.
