INTRODUCTION
Push and pull systems determine when and where to move material in a production process. A push system is characterized by a make to stock environment and a pull system is characterized by a make to order. An appropriate system that would cater to the requirements of the company has to be selected. A distinction is made between push and pull production systems based on the trigger point. The push system is based on customer orders, while a pull system is based on forecasts. In short, push systems can be compared with MRP systems that utilize past information to forecast the future customer demands. In the case of a pull system the difference between the safety stock point and the state of current
