This paper examines static and dynamic policies for replenishing and allocating inventories amongst N retailers located along a fixed delivery route. Each retailer faces independent, normally-distributed period demand and incurs a proportional holding or backorder cost on end-of-period...

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...

This paper examines the impact of group purchasing organizations (GPOs) on healthcare-product supply chains. The supply chain we study consists of a profit-maximizing manufacturer with a quantity-discount schedule that is nonincreasing in quantity and ensures nondecreasing revenue, a...

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...

The authors are indebted to Professor Andrew Szendrovits of McMaster University for pointing out that [Szendrovits, A. Z. A comment on "Optimal and system myopic policies for production/inventory assembly systems". Management Science, this issue.] the definition of echelon holding cost in...
