Enterprise-wide optimization of total landed cost at a grocery retailer. (OR Practice).
May 1, 2003... We describe an enterprise-wide tool for tactical planning at a grocery retailer. The tool enables a "total landed cost" perspective by coordinating decisions across functions of the supply chain. It dynamically optimizes across logistics,...

Programmatic Risk Analysis for critical engineering systems under tight resource constraints. (Articles).
May 1, 2003... Managers of complex engineering development projects face a challenge when deciding how to allocate scarce resources to minimize the risks of project failure. As resource constraints become tighter, balancing these failure risks is more...

Incentive efficient control of a make-to-stock production system.
May 1, 2003... This paper considers a principal-agent variant of the classical make-to-stock single-server queueing system. The principal incurs all costs for holding inventory and backordering demand. The agent dynamically controls the production rate at the...

Improving crew scheduling by incorporating key maintenance routing decisions.
May 1, 2003... Crew costs are the second-largest operating expense faced by the airline industry, after fuel. Thus, even a small improvement in the quality of a crew schedule can have significant financial impact. Decisions made earlier in the airline...

Offer stack optimization in electricity pool markets.
May 1, 2003... We consider a generator making offers of energy into an electricity pool market. For a given time period, it must submit an offer stack, consisting of a fixed number of quantities of energy and prices at which it wants these quantities...

Pricing and replenishment strategies in a distribution system with competing retailers.
May 1, 2003... We consider a two-echelon distribution system in which a supplier distributes a product to N competing retailers. The demand rate of each retailer depends on all of the retailers' prices, or alternatively, the price each retailer can charge for...

A procedure to find discrete representations of the efficient set with specified coverage errors.
May 1, 2003... An important issue in multiple objective mathematical programming is finding discrete representations of the efficient set. Because discrete points can be directly studied by a decision maker, a discrete representation can serve as the solution...

Large deviations-based asymptotics for inventory control in supply chains.
May 1, 2003... We consider a model of a capacitated single-class supply chain consisting of production facilities (stages) in tandem. External demand is met from the available finished goods inventory maintained in front of the most downstream facility;...

An approximation scheme for stochastic integer programs arising in capacity expansion.
May 1, 2003... Planning for capacity expansion forms a crucial part of the strategic-level decision making in many applications. Consequently, quantitative models for economic capacity expansion planning have been the subject of intense research. However,...

Restaurant revenue management.
May 1, 2003... We develop two classes of optimization models to maximize revenue in a restaurant (while controlling average waiting time as well as perceived fairness) that may violate the first-come-first-serve (FCFS) rule. In the first class of models, we...

Multilevel lot sizing with setup times and multiple constrained resources: internally rolling schedules with lot-sizing windows.
May 1, 2003... In this paper a new time-oriented decomposition heuristic is proposed to solve the dynamic multi-item multilevel lot-sizing problem in general product structures with single and multiple constrained resources as well as setup times. While...

A note on "inventory models with cost changes". (Technical Note).
May 1, 2003... This note is concerned with the inventory models with finite horizon and cost changes. We presented more specific results on the optimal inventory policy than those in previous papers and showed that some of the results in Lev and Weiss' (1990)...
