TAILIEUCHUNG - Three stage supply chain model with two warehouse, imperfect production, variable demand rate and inflation

This study develops an integrated production inventory model from the perspectives of vendor, supplier and buyer. The demand rate is time dependent for the vendor and supplier and buyer assumes the stock dependent demand rate. As per the demand, supplier uses two warehouses (rented and owned) for the storage of excess quantities. | Three stage supply chain model with two warehouse imperfect production variable demand rate and inflation International Journal of Industrial Engineering Computations 4 2013 81 92 Contents lists available at GrowingScience International Journal of Industrial Engineering Computations homepage ijiec Three stage supply chain model with two warehouse imperfect production variable demand rate and inflation .

The demand rate is time dependent for the vendor and supplier and buyer Received in revised format assumes the stock dependent demand rate. As per the demand supplier uses two warehouses November 2 2012 rented and owned for the storage of excess quantities. Shortages are allowed at the buyer s part Accepted November 2 2012 Available online only and the unfulfilled demand is partially backlogged. The effect of imperfect production 6 November 2012 processes on lot sizing is also considered. This complete model is studied under the effect of Keywords inflation. The objective is to minimize the total cost for the system. A solution procedure is Supply chain model developed to find a near optimal solution for the model. A numerical example along with Two warehouse sensitivity analysis is given to illustrate the model. Partially backlogging Imperfect items Variable demand rate and inflation 2013 Growing Science Ltd.
