Abstract�� To meet the requirements of human machine engineering and alternative selection of process routes in CAPP, an approach to visually plan and estimate the multi-process routes based on graphic components and process nets was put forward. According to the elements of process route, common and typical graphic components including operation component, equipment component, feature component and transfer component were built, and these components were represented by four kinds of attributes: identification, display, technology and estimation. Thus, process routes were constructed by dragging graphic components and were presented by process net so that multiple process routes can be planned simultaneously and visually. Dijkstra algorithm was adopt to estimate the performance indexes of the multi-process routes, and to select the optimal process route. An application example for panning the process routes of an aircraft structural part was illustrated. The approach proposed is able to properly present the process planer’s intents and effectively carry out analyses and decision-makings for planning process routes.
