A New Model of Card Controlling System by the Combination of Production Control Policies

One of the main efforts in a pull system to meet the final goal of Just-In-Time (JIT) is to decrease Work-In-Process (WIP) without reducing throughput rate and service level. This paper proposes a new hybrid control policy using Kanban, Base Stock and CONWIP to form the final construction of production plan, and then the function of new model is shown by a 3 stage case study with probabilistic parameters. The results obtained using simulation and solving various problems indicate that the inventory level is reduced to an acceptable range. Also, Data Envelopment Analysis (DEA) is implemented for the evaluation and verification of the proposed policy with functional indicatives.
