SIMULATION MODEL FOR IMPROVED PRODUCTION PLANNING AND CONTROL THROUGH QUALITY, CYCLE TIME AND BATCH SIZE MANAGEMENT

Production planning and control (PPC) systems are the base of all production facilities. In today’s surroundings, having a good PPC system generates lots of benefits for the companies. But, having an excellent PPC system provides great competitive advantage and serious reduction of cost in many fields. In order to get to a point of having excellent PPC, the companies turn more and more to the newest software tools, for simulations as an example. Considering today’s advanced computer technology, by using the simulations in this area, companies will have strong asset when dealing with different kinds of wastes, delays, overstock, bottlenecks and generally loss of time. This model is applicable in almost all production facilities. Taking into account the different scrap percentages for the pieces that form the end product, a detailed model and analysis were made in order to determine the optimal starting parameters. At first all the conditions of the company were determined, conceptual model was created along with all assumptions. Then the model was verified and validated and at the end a cost benefit analysis was conducted in order to have clear results.
