An inventory model with temporary price discount when lead time links to order quantity

Abstract

This paper presents effects of a temporary price discount offered by supplier on a retailer’s replenishment policy, when lead time is linked to order quantity. A decision process for retailers is developed in deciding whether to adopt a regular or special order policy during a temporary sales period. Optimal special order quantity is determined by maximizing total cost saving between special and regular orders, and illustrated by several numerical examples along with sensitivity analysis of optimal solution.
