We address the problem of determining optimal ordering and pricing policies in a finite-horizon newsvendor model with unobservable lost sales. The demand distribution is price-dependent and involves unknown parameters. We consider both the cases of perishable and non-perishable inventory. A very general class of demand functions is studied in this paper. We derive the optimal ordering and prici...

Following abstraction and treatment water becomes a vulnerable and perishable product. It is vulnerable in that the integrity of systems used for the storage and distribution of water can be damaged and contamination through ingress can occur. It is perishable in that its microbial quality can deteriorate due to the bacteria remaining after treatment growing on the residual nutrient in the wate...

This study addresses the production planning problem for perishable products, in which the cost and shortage of products are minimized subject to a set of constraints such as warehouse space, labor working time and machine time. Using the concept of postponement, the production process for perishable products is differentiated into two phases to better utilize the resources. A two-stage stochas...

In this paper we propose an approach for solving problems of optimal resource capacity allocation to a collection of stochastic dynamic competitors. In particular, we introduce the knapsack problem for perishable items, which concerns the optimal dynamic allocation of a limited knapsack to a collection of perishable or non-perishable items. We formulate the problem in the framework of Markov de...

In current markets of perishable goods such as fish and vegetables, sellers are typically in a weak bargaining position, since perishable products cannot be stored for long without losing their value. To avoid the risk of spoiling products, sellers have few alternatives other than selling their goods at the prices offered by buyers in the markets. The market mechanism needs to be reformed in or...

We examine whether the Coase conjecture [7, 14, 4, 10] is robust against slight ability of commitment of the monopolist not to sell the durable goods to consumers. We quantify the commitment ability in terms of the speed that the durable goods perish, while keeping the time between the o ers small. We demonstrate that the slight commitment capability makes a substantial di erence by constructin...

We study a perishable inventory system that requires to maintain a fresh and large quantity of inventory at all times. For example, certain pharmaceuticals are kept for emergency preparedness and response operations. We aim to maximize the profit by optimizing the joint problem of the ordering and issuing policies while maintaining a minimum amount of perishable inventory. First, we consider a ...
