Amount of off grade optimization in the continuous polymerization businesses

Uncertainty in demand and product types being excessive brought the importance of production costs out once again. In the continuous polymerization, during the transition process between the product, productions that comply with none of the quality spectrum and named as transition product depending on product transition time, product type and working capacity brought out. The resulting product is to bear because of the continuous process.In this thesis study, planning of product transition sequence, determining the minimum working transition level are aimed. Within the scope of this study the total amount of stock and order waiting time are followed as performance criterion.Recommended new methodology is aimed to optimize the total amount of stock, total order waiting time and amount of transition product by depending in each other. It is used the real data that is obtained from continuous polymerization businesses with the aim of testing the methodology that brought out by combining Simulation and 6 Sigma techniques.
