Abstract

En 中文

Concurrent process engineering is concerned with the integration of traditionally separate individual activities in process design covering process, mechanical, civil and control phases, so that all life-cycle issues including safety, environmental impact, cost, operability and commissioning can be considered as early as possible in establishing manufacturing process. It seeks to enable multi-disciplinary teams, sometimes working at different sites to work cooperatively. The approach can be envisaged at three levels of conceptualisation related to design objects (process plants), design teams and a project manager, who controls the work flow among the teams. The life-cycle data of the design objects can be represented in a multi-dimensional object-oriented format using STEP/EXPRESS, while project teams are modelled by agents which provide tools for the specialist groups and carry out high level operations of application tools. Coordination of the agents depends on modelling the work flow so as to control concurrent activity and sequencing of sub tasks.
