Abstract

Companies have been trying to maximize productivity from their available resources. Only one resource can limit the throughput of the whole system. This resource, the so called “bottleneck” causes inability of a system to respond to sudden changes in demand as a result of capacity restriction. Different production controlling mechanisms have their own way to direct materials through the system in which they can affect the speed of the flow. This study is aimed to at recommending important decision variables for controlling the material flow of both traditional non-hybrid production control systems and hybrid systems under restricted conditions as well as identifying the advantages and disadvantages of each system. Results from the study will give the best alternative for the production system under unbalanced conditions.
