Abstract: A serial supply chain which consists of a raw material supplier, a manufacturer, a distribution center and a retailer is considered in this paper. Time-varying delivery is in the presence between manufacturer facility and the retailer warehouse in the supply chain. Delivery time function is developed based on practical data analysis. The total cost model is derived and a new search algorithm is established. The corresponding Decision Support System is developed by using Active X technology to embed matlab in visual basic. Finally, sensitivity analysis is made to help decision makers achieve a lower total cost in practice.

Key words: time-varying delivery, JIT, delivery time, cost in transit, production batch size
