Method for Configuration Design over the Lifecycle of Reconfigurable Machine Tools

A method to generate a configuration path for changing requirement scenario in the early stage of configuration design for Reconfigurable Machine Tools (RMTS) was proposed. Firstly, the cost models of machine tools for the fixed-demand periods were given, and solved by using integer linear programming method to gain the optimal configuration of RMT for each fixed-demand period. Then, a concept for configuration similarity of RMT was presented,and a GA is used to obtain the alternative configuration decisions of the fixed-demand periods. Finally, reconfigurability between adjacent demand periods was evaluated by computing the configuration similarity, and a GA is used again to find the optimal configuration path that across all demand periods over the lifecycle of the RMT.
