Abstract: First the connotation of production-engineering-oriented virtual manufacturing (PEOVM) is discussed, and a corresponding three-view architecture is put forward, which composed of planing-view, modeling-view and optimization & evaluation-view. The couple-relation among these views is established, where planning view is the main body, modeling view is the support and optimization & evaluation view is the goal, so that a three-dimension solving-space for design optimal virtual production system is formed. It uncovers the evolutive procedures of multi-level planning activities for production system with the information progress from static process plan to dynamic production plan, reflecting the optimization from quantitative to qualitative and the virtual execution in virtual reality (VR) environment. Then an engineering example is used to illustrate the evolutive procedures for obtaining an optimal scenario in virtual production system planning. By this means, an effective method is provided for enterprise to implement the planning of real production system.
