— Recently years, it is becoming important to build a "Closed Loop Supply Chain (CLSC)" that collects used products and reuses them. A CLSC is a way of recovering used products from the market and reusing parts to reduce production costs and improve the profit of the entire supply chain. Also, the Product Life Cycle has been shortened due to diversification of products and demand management becomes necessary to make total sales profit. Therefore, I thought two stage demand management with recycle parts in CLSC for Extending product life cycle is promising way. In fact, it is difficult to control the second demand amount for profit and the collection rate to satisfy it, so this research on addressing these problems is effective. Further, I formulate the method for the production planning with two stage demand management by Mixed Integer Programing optimization model. And maximize SCM total profit by controlling recovery rate and second demand start time.
