Background: One proposal to increase kidney transplantation is to exchange kidneys between pairs of ABO-incompatible (or crossmatch -incompatible) living donors and their recipients. One variation that has greater potential exchanges living donor…

We build a discrete time, serially correlated stochastic demand, nonstationary, finite horizon, capacity expansion model that includes (1) economies of scale in capacity costs, (2) positive expansion lead times, and (3) a fixed maximum cumulative…

This paper derives the optimal simultaneous capacity and production plan for a high volatility, short life-cycle, produce-to-stock, product that requires (at least some) dedicated production capacity. Capacity can be reduced as well as added, at…

We investigate a simple dynamic model of firm behavior in which firms compete by investing in capacity that is used to provide a good or service to their customers. There is a fixed total market of customers whose demands for the good or service…

In this paper we present a canonical setting that illustrate the need for explicitly modeling interactions between manufacturing and marketing/sales decisions in a firm. We consider a single firm that sells an innovative product with a given…

Background. There is sufficient cadaveric kidney supply to meet the demands of suitable transplant candidates. The comparative equity and efficiency characteristics of alternative organ allocation strategies have not been rigorously examined.…

This paper addresses the horizontal coordination between production units located in different countries within a supply chain in a changing environment. Our model incorporates (1) congestion and delay through uncertainties in demand and…

The decentralized supply chain management scheme of Lee and Whang (1999) can be viewed as operationalizing the decentralized management scheme implicit in Clark and Scarf (1960). This paper proposes the use of what are called responsibility…

Consider selling to a news vendor. A manufacturer markets a product through a retailer who has one opportunity to order before demand is realized. Because of characteristics of the product, norms of the industry, or aspects of the manufacturer-…

The present paper applies the mismatch hypothesis to the contemporary American film industry. This proposition, successfully applied to the stock market, holds that failing to gain the attention of the critics who specialize in a product’s…

An integrated marketing and manufacturing innovation in this paper is a new substitute product having different attributes and ( possibly) a different unit cost than the current products. We develop a simple single period model that is a…

Advances in information system technology have had a huge impact on the evolution of supply chain management. As a result of such technological advances, supply chain partners can now work in tight coordination to optimize the chain-wide…

After reformulating Clark and Scarf’s (1960) classical serial multi-echelon model so that the lead time between adjacent echelons is one week (period), the option to expedite between each resulting echelon is added. Thus, each week requires a…

Some firms, particularly in high-tech, appear to view technology and cost leadership as separate and distinct ways of achieving high profiles within a given product market. In contrast, we develop a model of technology competition suggesting that…

This paper studies time-based competition in imperfect securities markets, linking IT investment decisions, information processing delays and trading strategies. At the IT investment stage, traders trade off the cost of IT against their…

World-Class Manufacturing has received a great deal of attention in the past few years, drawing largely on successful Japanese manufacturing practices. There has also been a separate explosion in the use of conjoint analysis to determine customer…

We consider a manufacturer introducing a new product into a distribution channel and examine what wholesale price should be charged. The setting in many ways is simple. The channel is abbreviated with the manufacturer selling directly to the…

We explore the critical linkages between attributes of manufacturing strategy and attributes of marketing strategy. Generic linkages drawn from a significant managerial sample are presented and discussed. A second, independent sample is used to…

Recent tests of the capital asset pricing model by Fama and French (1992) showed that there is no significant relationship between the average return and systematic risk of common stocks. We propose two econometric methods to improve the…

We analyze single parameter process design problems that typically entail minimizing the sum of convex and concave functions. We transform such problems into a tractable form, and obtain sharp characterizations of the original problem. Solution…
