An architecture for process modelling and execution support

Abstract

This paper discusses concepts and techniques supporting modelling, planning and execution of design activities in distributed design environments. The task of planning, executing, and supervising the design processes has become so complex that it itself requires advanced computer support facilities. We propose extended planning facilities exploiting old design projects. The planning functions form a basis for a larger framework for decision and execution support. In what follows, we discuss the phases of a design process, especially planning including process model generation using history based planning techniques. Finally, we present our prototype of an architecture for a design process management system (DPMS). The DPMS architecture promotes highly autonomous execution of system designs. The system has been used in the electronic design automation area. The concepts described here, however, are also applicable to other design domains.
