Robust Storage Assignment in Unit-Load Warehouses

Ang, Marcus; Lim, Yun Fong; Sim, Melvyn - In: Management Science 58 (2012) 11, pp. 2114-2130

Assigning products to and retrieving them from proper storage locations are crucial decisions in minimizing the operating cost of a unit-load warehouse. The problem becomes intractable when the warehouse faces variable supply and uncertain demand in a multiperiod setting. We assume a...

Note: An Improvement to the Dynamic Cycle Lengths Heuristic for Scheduling the Multi-Item, Single-Machine

Leachman, Robert C.; Xiong, Zhong K.; Gascon, André; … - In: Management Science 37 (1991) 9, pp. 1201-1205

A heuristic scheduling policy for multi-item, single-machine scheduling systems facing stochastic, time-varying demands was previously introduced by Leachman and Gascon. In this technical note we provide an improvement to the calculations of the policy. Simulation tests of the revised version of...

A Modeling Framework for Coordinating Promotion and Production Decisions within a Firm

Sogomonian, Aram G.; Tang, Christopher S. - In: Management Science 39 (1993) 2, pp. 191-203

This paper presents a modeling framework for evaluating the benefits of coordinating promotion and production decisions … production. The modeling framework consists of the development of a baseline model and an integrated model. In the baseline … (integrated) model, the firm would consider those promotion and production decisions separately (jointly). For each of the models …

File and Work Transfers in Cyclic Queue Systems

Sarkar, D.; Zangwill, W. I. - In: Management Science 38 (1992) 10, pp. 1510-1523

A cyclic queue has one server and n nodes, where each node has its own distinct type of customers that arrive from the outside. The server visits the nodes cyclically, serving the customers first at node 1, then at node 2, and so on through node n, and then repeating from node 1 again. Setup...

Ordering and Production Decisions with Supply Quality and Demand Uncertainty

Bassok, Y.; Akella, R. - In: Management Science 37 (1991) 12, pp. 1556-1574

In this paper, we solve a production planning problem that has a direct bearing on the cost to a facility of vendor … the optimal production level, and the raw material order quantity which minimize the total expected cost subject to … capacity and release level constraints. The results obtained by our model (the integrated model) show that the production level …

Asymptotic Optimality of Order-Up-To Policies in Lost Sales Inventory Systems

Huh, Woonghee Tim; Janakiraman, Ganesh; Muckstadt, John A. - In: Management Science 55 (2009) 3, pp. 404-420

We study a single-product single-location inventory system under periodic review, where excess demand is lost and the replenishment lead time is positive. The performance measure of interest is the long-run average holding cost and lost sales penalty cost. For a large class of demand...
