An FMS Optimal Model Based on Extended High Level Global Evaluation Petri Net
Zhang Fu-liang · Computer Integrated Manufacturing Systems · 2004
A flexible manufacturing system (FMS) is a complex discrete-event dynamic system. Based on the extended high level evaluation Petri Net (EHLEP-N), the extended high level global evaluation Petri Net (EHLGEP-N) with global structure is proposed to model FMS. The combination of EHLGEP-N with the genetics-based minimum balance (GMB) algorithm is taken as an example to address that combining EHLGEP-N with intelligently optimal methods improves not only the integral performance of FMS' optimal scheduling but also the visibility of the scheduling.
