摘要：A pre-pack is a collection of items used in retail distribution. By grouping multiple units of one or more stock keeping units (SKU), distribution and handling costs can be reduced; however, ordering flexibility at the retail outlet is limited. This paper studies an inventory system at a retail level where both pre-packs and individual items (at additional handling cost) can be ordered. For a single-SKU, single-period problem, we show that the optimal policy is to order into a band with as few...

摘要：This paper studies appointment scheduling for a combination of routine patients who book well in advance and last-minute patients who call for an appointment later that same day. We determine when these same-day patients should be scheduled throughout the day, and how the prospect of their arrivals affects the appointment times of the routine patients. By formulating the problem as a stochastic linear program, we are able to incorporate random and heterogeneous service times and no-show rates,...

摘要：The basis for this article is an information-processing view of the UN's cluster approach. We use agent-based modeling and simulations to show that clusters, if properly utilized, encourage better information flow and thus facilitate effective response to disasters. The article intends to turn the attention of the humanitarian community to the importance of sharing information and the role of cluster leads in facilitating humanitarian aid. Our results indicate that if cluster leads act as info...

摘要：Using a unique, item-level data set, we examined benefits to downstream firms (distributors) from the decision-transfer component of vendor-managed inventory (VMI), the feature that distinguishes VMI from other information-sharing, collaborative supply chain programs. Our major findings are that the decision-transfer component of VMI adds significant benefits to the downstream firm in terms of inventory and stockout reductions above and beyond information sharing, and that these two benefits m...

摘要：We study a strategic information management problem in the export-processing trade, where the buyer controls the raw material input and sales and the producer is responsible for production. The production is vulnerable to random yield risk. The producer can exert a costly effort to acquire the private yield rate information and discretionarily share it with the buyer. We develop a sequential Bayesian game model that captures three key features of the systemendogenous information endowment, vol...

摘要：This study investigates firms' R&D cooperation behavior in a supply chain where two firms first cooperate in R&D investments and then decide the production quantity according to a wholesale price contract. By using a concept named contribution level that measures a firm's technological contribution to the R&D cooperation in the supply chain, we show that both firms can achieve win-win via cartelization only if their contribution levels are Pareto matched, i.e., when each firm's contribution le...

摘要：This article studies the impact of modular assembly on supply chain efficiency. In the modular assembly approach, a manufacturer acquires pre-assembled modules from its suppliers, rather than the individual components, as in the traditional assembly approach. We analyze the competitive behavior of a two-stage modular assembly system consisting of a manufacturer, and a supplier who pre-assembles two components into a module. The firms can choose their own inventory policies and we show the exis...

摘要：We consider assortment optimization problems under the multinomial logit model, where the parameters of the choice model are random. The randomness in the choice model parameters is motivated by the fact that there are multiple customer segments, each with different preferences for the products, and the segment of each customer is unknown to the firm when the customer makes a purchase. This choice model is also called the mixture-of-logits model. The goal of the firm is to choose an assortment...

摘要：The Principle of Least Action is the foundational principle of fundamental physics. Application of this principle to the supply chain naturally results in an uncertainty principle linking variation in production to variation in net-inventory. The model also provides an easy means of determining the stationary distribution of net-inventory for a variety of control strategies. The formalism results in a control strategy that outperforms commonly used control methods.
