We formulate a model for determining the optimal pricing, order quantity and replenishment period for perishable items with price-dependent and time-dependent demand. The items have a fixed shelf-life, and the demand rate decreases linearly in the selling price and polynomially over the time...

Partial vertical ownership describes a situation in which a firm holds financial shares in either its supplier (referred to as partial backward integration) or its customer (partial forward integration). We study the effect of such financial interconnectedness on two operational decisions:...

This work deals with pricing of “virtual” products, i.e., products that a retailer can supply after demand has been realized. Such products allow the retailer to avoid holding costs and ensure timely fulfillment of demand with no risk of shortage. Demand is commonly price-dependent and...

We analyze pricing and protection (digital rights management) strategies in a two-echelon supply chain that consists of a manufacturer and a retailer of digital products. The demand for the legal (non-pirated) product, which depends on both price and monetary investment in protection, is assumed...

This work presents an extension of the classical EOQ model for items with a fixed shelf life and a declining demand rate due to a reduction in the quality of the item in the course of its shelf-life. The demand rate, reflecting consumer preference for fresh items, is a polynomial function of the...
