摘要：In the realm of service parts management, customer relationships are often established through service agreements that extend over months or years. These agreements typically apply to a piece of equipment that the customer has purchased, and they specify the type and timing of service that will be provided. If a customer operates in multiple locations, service agreements may cover several pieces of equipment at several locations. In this paper, we describe a continuous-review inventory model f...

摘要：we present tractable algorithms to assess the sensitivity of a stochastic dynamic fleet management model to fleet size and load availability. In particular, we show how to compute the change in the objective function value in response to an additional vehicle or an additional load introduced into the system. The novel aspect of our approach is that it does not require multiple simulations with different values of the model parameters, and in this respect it differs from trial-and-error-based w...

摘要：In this paper, we analyze a facility location model where facilities may be subject to disruptions, causing customers to seek service from the operating facilities. We generalize the classical p-median problem on a network to explicitly include the failure probabilities, and analyze structural and algorithmic aspects of the resulting model. The optimal location patterns are seen to be strongly dependent on the probability of facility failure, with facilities becoming more centralized, or even ...

摘要：In this paper, we propose a novel optimization algorithm for examination timetabling. It works by alternating two phases; one based on a stochastic local search and the other on a deterministic local search. The stochastic phase is fundamentally based on biased random sampling that iteratively constructs schedules according to a matrix whose entries are the probability with which exams can be assigned to time slots. The deterministic phase, instead, consists of assigning (according to a given ...

摘要：Contract manufacturers sell capacity under different terms to different buyers. In a common practice, the supplier offers a market standard price and lead-time combination for products listed in its catalog. At the same time, it strikes contracts with some high-volume customers who require recurring delivery of a custom product at a short notice, usually timed to meet the buyer's production schedule. Whereas the manufacturer is obligated to satisfy demand from these customers, it can dynamical...

摘要：We consider a supply chain operating in an uncertain environment: The customers' demand is characterized by a discrete probability distribution. A probabilistic programming approach is adopted for constructing an inventory-production-distribution plan over a multiperiod planning horizon. The plan does not allow the backlogging of the unsatisfied demand, and minimizes the costs of the supply chain while enabling it to reach a prescribed nonstockout service level. It is a strategic plan that hed...
