The model is created for the integration production processes of materials delivery and materials assembly with
the PE tool. Integration of both these processes realized the modeling of the production process in connection
with work organization at large "which worker works in a required work area using the materials and quantity of a
required kind at the time of necessity."

MODELING AND VERIFICATION OF DESIGN PROCESS FOR WORKSTATION SYSTEM

Workstation system design is performed focusing on the work routing of the human workers for each site
workstation after process organization (workstation unit) in a construction working area. That is, in the
workstation system design, the work process "using what resources workers use and what operation they do" is
designed in consideration of human workability. Modeling of the workstation system design by the PE tool is
performed by the following procedures: 1) the site work routing plan corresponding to the materials assembly, 2)
resource planning required for materials assembly work, 3) the site workstation layout planning of a working area,
4) a setup of the prerequisite of task planning of work organization of two or more work contractor of operation,
and 5) regulation of the task planning of work organization of two or more work contractor of operation, and
analysis of work load

The model notation of the structure of the group work by cooperation, i.e., the work organization, was carried out
with the PE tool among the workers who become the standard and the workers of 1 upstairs of a construction story
in the case study. In case verifying the validity of modeling of the work system design using a human task
simulator, analyze load mitigation and working efficiency paying attention to the workload and the workability of
human work. Furthermore, the analysis to the posture and work load of human work which attaches vertical
material was shown by applying the simulator. By performing load analysis of modeling of the process of these
human task, or human work, data can be used as basic data these results at the time of creation of a "work standard
document."

CONCLUSION AND FUTURE RESEARCH SUBJECTS

The conceptual framework of "Cyber Concurrent Manufacturing (CCM)" system was indicated under a series of
join research IF7-II project. In order to continue the research in the last fiscal year (2003), a method of
modeling in detail by using a Process Engineering tool is proposed in this paper. Based on the proposed
modeling and its verification method, this fiscal year focused on "modeling of the design engineering processes
and the manufacturing processes by the PE tool", and "verification of the simulation of modeled data by the
3D-CG simulators", in connection with construction of curtain wall materials. The method is applied to a case
study which is to model construction processes of the "curtain wall" installation in a virtual construction site.
