Method of Parts Guidepath Network Formation in RMS

Parts guidepath network formation model is built based on graph theory. Machine physical layout algorithms are given to form three kinds of machine physical layout: planning layout, virtual manufacturing cell (VMC) layout based on quadratic assignment problem(QAP) model, and current layout. Automated guided vehicle (AGV) guidepath network formation algorithm, improving AGV guidepath network formation algorithm, and alternative guidepath network formation algorithm, which includes Dijkstra algorithm and pre-process algorithm, are given. The input data to the algorithms are distance matrix file and flow volume file, which expresses the distance information between the nodes in machine configuration graph and mix machine/process routings in one production period respectively. The eventual output results from the algorithms are optimal guidepath networks. Moreover the above algorithms are developed with Visual C++, the correctness of them is verified through examples test.
