An object-oriented modelling framework for automated manufacturing system

Proposed in the paper is an object-oriented modelling OOM framework, called a JR-net modelling framework, for automated manufacturing system AMS design. The proposed modelling framework, which consists of a graphical modelling tool called JR-net job resource relation-net and a modelling building procedure, is the same as the current practice of AMS design and is based on the OOM paradigm. In other words, a virtual prototype of AMS is constructed step-by-step based on a three-phase modelling approach: static layout modelling object model ; job flow modelling functional JR-net model ; supervisory control modelling dynamic model
