摘要：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, purchasing, and warehouse management, while considering the necessary joint replenishment economies and accounting for a wide variety of complexities, such as discounts on total order quantity. intermittent demand, multiple distribution centers, vendor deals an...

摘要：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 critical, less intuitive, and can benefit from the power of quantitative analysis. This paper describes the Advanced Programmatic Risk Analysis and Management model (APRAM), a decision-support framework for the management of the risk of failures of dependent en...

摘要：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 server and incurs a convex production cost. The principal cannot monitor the production rate but can draw inference from increases in the inventory level. Furthermore, by making payments contingent on the inventory level, the principal motivates the ag...

摘要：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 planning process, however, can reduce the number of options available to the crew scheduler. We address this limitation by delaying some of these earlier planning decisions-specifically, key maintenance routing decisions-and incorporating them within the crew s...

摘要：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 dispatched. We assume that the generator cannot offer enough power to substantially affect the market price, so the optimal response would be to offer energy at marginal cost. However. the market rules do not permit an arbitrary function, so the problem is to fi...

摘要：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 its product depends on the sales volumes targeted by all of the retailers. The supplier replenishes his inventory through orders (purchases, production runs) from an outside source with ample supply. From there, the goods are transferred to the retailer...

摘要：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 to the multiple objective problem at hand. However, the discrete representation must be of acceptable quality to ensure that a most-preferred solution identified by a decision maker is of acceptable quality. Recently, attributes for measuring the qualit...

摘要：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; unsatisfied demand is backlogged. Every stage orders from its upstream facility, thus production is constrained by the local production capacity and the availability of upstream inventory. We propose production policies in two separate cases: (1) when each fa...

摘要：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, much of the work in this area has been restricted to linear cost models and/or limited degree of uncertainty to make the problems analytically tractable. This paper addresses a stochastic capacity expansion problem where the economies-of-scale in expansion ...

摘要：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 use integer programming, stochastic programming, and approximate dynamic programming methods to decide dynamically when, if at all, to seat an incoming party during the day of operation of a restaurant that does not accept reservations. In a computational...
