Production and Material Planning in the Push and Pull Integrated System for Routine Products and Customers’ Orders

In this article the push and pull production system is investigated and the proper policies are presented to facilitate the production of customers’ orders and routine products. In this push and pull integrated manufacturing system we should choose the best production methods in different circumstances. Using linear programming is the method used to calculate the MPS and based on that MRP and SFC (for 4 weeks) are determined. Besides, the customers’ orders and all the material needed are added to the plan. The production system and raw material preparation are different in push and pull systems and the best decision should be made to consume the investment efficiency and deliver the production as customers need. In addition, a cycle of receiving orders from sales department is suggested. The results of calculation the plans for MPS, MRP, SFC, customers’ orders, etc. are determined. After calculating the MPS based on the push system, the orders are investigated for SFC and MRP system. Solving these models isn’t easy and soluble unless useful and comprehensive methods are used. This is a job sequences production line which is push and pull integrated system.
