Advanced Multiple Product Flexible Manufacturing System Modelling Using Coloured Petri Net

Abstract

The objective of this study is to analyse a pull type multi-product, multi-line and multi-stage flexible manufacturing system whose resources are subject to planned and unplanned breakdown conditions. To ensure a continual supply of the finished products, under breakdown conditions, the parts/materials move through alternate routes exhibiting routing flexibility. The machine resources are flexible in this study and are capable to produce more than one item. Every machining and assembly station has been equipped with automated inspection units to ensure the quality of the products. The system is modelled through coloured Petri net method and the impact of input factors has been shown on the performance of the system.
