This paper extends the deterministic EOQ model to reflect various optimizing criteria and alternative demand and price structures. Its primary purpose is to develop decision rules for the management of finished goods inventories, especially in retailing, where inventories are evaluated in the...

Material Requirements Planning or Manufacturing Resource Planning (MRP) systems originally were designed for a deterministic environment. Often, however, demand for finished products is uncertain and some type of buffering mechanism is necessary to provide desired levels of service. When the...

This paper examines a two-level distribution system consisting of a central warehouse (CW) supplying several branch warehouses (BW's), which, in turn, supply normally-distributed customer demands in a periodic-review environment. The CW replenishes system inventory using a base-stock...

In this paper, we focus on a single order cycle of a warehouse, serving N retailers where the only shipments allowed during the cycle are from the warehouse to the retailers. For a simple ship-up-to-S allocation policy, we develop both the exact cost model and a computationally tractable...

We investigate the problem of determining optimal planned leadtimes in serial production systems in which the actual procurement and processing times may be stochastic. The objective is to minimize the sum of inventory holding costs and job tardiness costs given a customer specified due-date. We...

This paper constructs and analyzes a multi-location inventory model to examine the value of warehouse risk-pooling in high service-level systems. Specifically, risk-pooling over the outside-supplier leadtime is examined. Two alternative systems of N identical retailers are formulated. In System...

This paper presents an approximation model for optimizing reorder points in one-warehouse N-retailer inventory systems subject to highly variable lumpy demand. The motivation for this work stems from close cooperation with a supply chain management software company, Syncron International, and...

This paper deals with mixed-model line balancing; i.e., the problem of combining line balancing with lot sizing in a multi-product environment. Recent developments in the area of multi-echelon production/inventory systems are applied, and algorithms are developed which determine the number of...

In multi-echelon repairable inventory systems with high set-up cost for order and/or high demand rates, the use of batch ordering may be more cost-effective than the common (S - 1, S) ordering policy. This paper addresses the issue of determining the optimal order batch size and stocking levels...
