    In this paper, we propose a new spatial interaction model for trip-chaining behavior that consists of a sequence of movements. Particularly, including the origin-destination constraints, we generalize the traditional entropy maximizing model to deal with trip-chaining behaviors. Traditional entropy models should be noted in terms of a theoretical derivation of the gravity model and its validity to real data. However, these models only deal with simple movements from origin to destination. On the contrary, people frequently visit several destinations in one trip and make a sequence of movements. In this regard of view, we extend the traditional entropy model, and propose a general framework for deriving trip-chain distributions incorporating a sequence of movements. This model enables us to estimate the trip-chain distribution to maximize the entropy under several constraints. Finally, we apply the model to a person trip survey in the Tokyo metropolitan area to examine the validity of the model.

  • MODELING THE EFFECT OF ORDER TIMING REDUCTION ON COORDINATING SUPPLY CHAIN INVENTORIES USING A SELECTIVE DISCOUNT STRATEGY

    Prior studies show that coordinating supply chain inventories with common replenishment epochs (CRE) provides benefit for vendor and buyers. Coordination using selective discount (SD) strategy allows some buyers to participate in the coordination scheme while other buyers continue to order as earlier. This can reduce the vendor's total cost more than that of all buyers participating and no buyer coordination in many circumstances. This paper considers the situation in which SD buyers place orders before CRE due to demand timing uncertainty. According to vendor flexibility, each SD buyer with early ordering incurs various levels of penalty cost to compensate for possible capacity loss for the vendor. The proposed models also allow for a more practical situation by considering the cases of equal and unequal probabilities of early ordering for SD buyers. The results indicate that the vendor's cost savings can be improved substantially based on the vendor flexibility, probability of early ordering, and the number of SD buyers involved in early ordering.

  • USING ORDER ADMISSION CONTROL TO MAXIMIZE REVENUE UNDER CAPACITY UTILIZATION REQUIREMENTS IN MTO B2B INDUSTRIES

    An order admission model is developed to introduce revenue management into MTO B2B industries. This solution is designed to resolve a common order management dilemma faced by manufacturers with severe seasonal demands. Considering the requirement that manufacturing industries be risk averse, the objective is to maximize the expected total revenue under a targeted capacity utilization constraint. The deterministic admission problem and its auxiliary model are presented and solved through an iterative dynamic programming algorithm. Through this algorithm, a reward-threshold order admission policy can be established at the beginning of the planning horizon, helping companies to achieve a balance between profitability and stability.

  • SAMPLING SITE LOCATION PROBLEM IN LAKE MONITORING HAVING MULTIPLE PURPOSES AND CONSTRAINTS

    Monitoring is a task of actual water collection in water quality assessment from lakes. In this paper, we consider the problem of locating water sampling sites which is a significant issue in the design of lake monitoring. We formulate the location problem so that it can handle multiple purposes and constraints arising in monitoring tasks, and design an algorithm based on iterated local search (ILS). In our experiments, we apply our formulation to the real situation of Lake Biwa, the largest freshwater body in Japan. The ILS based algorithm finds such a location of sampling sites from which we can achieve better estimation of water quality distribution over the entire lake than the existing location, where we assume the existence of the true distribution and generate it by Lake Biwa Basin Hydrological and Material Cycle Model. Also, we observe that some points are newly selected in the output solutions more frequently than others; such points can be interpreted as potential sampling sites.
