摘要：This work presents a modelling approach for nonlinear process plan (NLPP) implementation in discrete event manufacturing system (DEMS). NLPP is used for the building of the modular structure of an Object Observable Petri Net model of DEMS. The general capabilities of DEMS are defined by resources’ operation templates and the transition incidence relation. Based on system specification and NLPP executed in the system, the modular model of DEMS is defined. The required steps for constructing a modular model through the integration of resource models are presented. The proposed approach to modular modelling is illustrated by means of a sample DEMS and an example of NLPP.
