MODELING AND SIMULATION METHOD TO FIND AND ELIMINATE BOTTLENECKS IN PRODUCTION LOGISTICS SYSTEMS

The paper presents the method of modeling and simulation of production logistics systems. Finding and eliminating bottlenecks is the main goal of this method. Production system is identified using IDEF0 methodology. The model is constructed as a system of equations, which describe the elements of the production system in the relationships between them. The special category of resources – logistics resources is distinguished. A special parameter called “flow ” is introduced. The algorithms to compute this parameter and to use it in order to find and eliminate bottlenecks are described. The results of simulation experiment are presented.
