“Wrong-product” delivery - the delivery of a product different from that desired - is a significant, but as yet unexplored problem in supply-chain management research. There are basically two reasons for wrong-product delivery: either the wrong product is mistakenly ordered or the right...

We consider a distribution system consisting of a System Administrator (SA) and N retailers managed under dynamic allocation and static routing policies. We study the system under two scenarios: (a) the up-to-date information scenario, under which the SA has access to the inventory levels at the...

A one-warehouse N-retailer deterministic inventory system is examined. The objective is to determine the stocking policy which minimizes average system cost per unit time over the infinite time horizon. Necessary properties of an optimal policy are derived, and optimal solutions for the...

We are indebted to Jack Muckstadt and Howard Singer for calling our attention to two errors in [Graves, S. C., Schwarz, L. B. 1977. Single cycle continuous review policies for arborescent production/inventory systems. Management Sci. 23 (5, January) 529-540.].

More than twenty years after the publication of the Linear Decision Rule (LDR) of Holt, Modigliani, Muth, and Simon (HMMS), the LDR remains an implementation failure. No company is reported to be using it. This paper hypothesizes that the reason for this failure may be a very simple one: the...

This paper develops and analyzes a principal-agent model for product specification and production motivated by Ücore buyingÝ decisions at an automobile manufacturer. The model focuses on two important elements of the ÜcoreÝ buyer's responsibility: (1) assessing the supplier's capability, and...

In this thesis we examine several business scenarios in which the owner (principal) of an inventory system, who is risk-neutral, delegates its design and/or implementation to an agent (internal manager, external supplier, or consultant) whose hidden effort influences the duration of the item's...

This dissertation develops optimal/near-optimal allocation and replenishment policies for a multi-level, periodic-review, fixed-route logistics system which is comprised of a Logistics Center and several non-identical retailers located along a fixed route. The Logistics Center coordinates the...

We examine a single-item, periodic-review inventory system with stochastic leadtimes, in which a replenishment order is delivered immediately or one period later, depending probabilistically on costly effort. The objective is to determine a joint inventory policy and effort-choice strategy that...
