We settle an open conjecture regarding the newsvendor game. We prove that its core is always nonempty for all possible joint distributions of the random demands. We give sufficient conditions under which the core is a singleton, or at a core allocation every newsvendor shares a nonnegative cost

In the classical Harris-Wilson (1915) inventory model all the cost associated with the formula was taken to be constant and which also does not depend on any quantity. There are many practical situations where this is not true. This paper considers an inventory model where the carrying cost...

This paper deals with the problem of determining the retailer's optimal price and order quantity simultaneously when both holding cost and ordering cost are fuzzy numbers. The fuzzy model under the fuzzy arithmetical operations of Function Principle is proposed. The final purpose is to find...

Working in collaboration with Spain-based retailer Zara, we address the problem of distributing, over time, a limited amount of inventory across all the stores in a fast-fashion retail network. Challenges specific to that environment include very short product life cycles, and store policies...
