MODELING METHOD OF CONTROL TARGET SYSTEM BASED ON EXTENDED PETRI NET AND CONTROLLER BASED ON EXTENDED PETRI NET

摘要

PPROBLEM TO BE SOLVED: To provide a controller based on an extended Petri net useful for a design or improvement of a physical distribution system. PSOLUTION: This controller 101 based on the extended Petri net comprises a computer system having input means 105, 106, a display means 104, a Petri net model design means 111, and a Petri net execution means 112, connectable with external control target equipment 108. Thereby, control of a system, monitoring of the system, and performance evaluation of the system can be performed by one Petri net model. PCOPYRIGHT: (C)2007,JPO&INPIT
