Modern manufacturing modeling using patri nets

Since the Second World War a significance changes have beenoccurring in industry. And the most challenges faced industry are productionmoving towards sophisticated high quality products, economy of scale hasbeen replaced by economy of scope, jerky demands are progressively replacingsteady demands and competitiveness is becoming a world wide phenomena.These challenges required highly flexible and automatedmanufacturing system. This flexibility provides a greater number of choices ofroutings and resources, and allows higher productivity; it imposes achallenging problem of allocating the given resources to various processes foreach product, and scheduling activities effectively. So, using a comprehensivemodeling and scheduling approach is very urgent.Traditional modeling and scheduling approaches have difficulties withformulation and/or the solution methods. Approaches such as linear (integer)programming, search, and network models like CPM, PERT and queuingnetworks can provide effective solution methods but have formulationdifficulties in handling shared resources, routing flexibility, concurrency, lotsize, etc. approaches such as algebraic models have difficulties in providingefficient solution methods.Petri net can dedicated as one of the powerful tool which can supportnot only the specification activity, but also the evaluation of the behavior of thesystem starting from the model provided by the specification.This work provides a computer program that addresses the modeling,planning and scheduling problems of a manufacturing system by using timedplace Petri net TPPN. The approach proposed in this research is divided intothree main items. The first concerned with a database file that contains all datain the manufacturing model and its related Petri network captured from the
