We introduce the nonatomic supermodular game, where no playerʼs action has any discernible impact on other playersʼ payoffs and yet strategic complementarities prevail among all playersʼ types and actions. For both semi-anonymous and anonymous games, we show that monotone equilibria form...

We concentrate on a principal and agent system often seen in supply chain management studies. Under reasonable conditions, we show that a nearly systematic three-step method can be used to find coordination contracts for the system. The number of terms involved in our contract is in some sense...

This paper studies a new multi-product dynamic lot sizing problem, where the inventories of all products are replenished jointly with the same quantity whenever a production occurs. Such problems may occur in poultry and some chemical industries. We first introduce the general problem that...

In this paper we study the production scheduling problem for a two-stage flow shop in which there are options of outsourcing some operations to subcontractors. The basic objective is to look for a production schedule that can optimally utilize the resources of both the in-house production and...

The eastern route of the South-to-North Water Diversion (SNWD-ER) project is a massive-scale interbasin system to transfer water from the Yangtze River to North China. With the infrastructure construction close to completion, the project is now faced with many complicated operations management...

This paper addresses two important issues that may affect the operations efficiency in the recycling industry. First, the industry contains many small-scale and inefficient recycling firms, especially in developing countries. Second, the output from recycling a waste product often yields...

This paper studies the problem of improving the operations efficiency for retrieving inbound containers in a modern automatic container terminal. In the terminal, when an external truck arrives to collect a container stored in a specific container block, it waits at one end of the block where an...

This paper develops an adverse selection model for a two-stage supply chain with one supplier, one retailer, and a potential outside entrant supplier who makes a partially substitutable product. The work is different from most research on entry deterrence that only considers a single-stage...

The purpose of this paper is to investigate an one-supplier-one-retailer supply chain that experiences a disruption in demand during the planning horizon. While demand uncertainty has long been a central research issue in supply chain management, little attention has been given to disruptions...
