Optimal Pricing, Quality Investment and Replenishment Policies for Perishable Items
Keywords:
Abstract
This paper discusses optimality of replenishment cycle time, selling price, quality investment cost and order quantity with simultaneous deterioration of quality and physical quantity. Most of models assume the quality of items does not decay before their expiration dates. In practice, the quality of many products often deteriorate over time, applying quality investment makes us able to maintain freshness of items. The quality of an item usually plays an important role in influencing factor of demand for product. Demand rate is dependent on the selling price and the quality of an product. The model seeks to maximize the total profit of the model by determining the optimality of decision variable. In order to analyse the behaviour of the model and numerical example accompanied by sensitivity analyses of key parameters of the model are provided.
