comparison between the performances of pull and push systems using discrete event simulation

This study considers push and pull strategies to control production systems with random processing times for multistage manufacturing inventory systems. in this paper, the behavior of push and pull production systems is examined to explain the superior performance of push systems. on the production system, the phrases push and pull have been defined to explain a variety of production and distribution environments. to some, the difference refers to an important attribute that can be defined by observing the methods for managing material flow on the production lines. to others, pull and push can be considered in phrases as a special method for managing production schedules. this paper considered the push and pull systems and developed a framework to compare multistage production systems based on work-in-process (wip) and throughput (tp) tradeoffs. in this paper, according to the way of defining the systems and the desired criteria in evaluating the efficiency, the push system is a better option. finally, the proposed model with generated different examples is simulated in arena software to analyze the model performance. the results obtained from models and simulation proved the push system is the suitable method for this problem. the pull system also appears more general in its applicability than traditional pull systems.
