摘要：The purpose of this paper is to develop a general framework for supply contracts in which portfolios of contracts can be analyzed and optimized. We focus on a multi-period environment with convex contract, spot market, and inventory holding costs. We specialize the model to the case of a portfolio consisting of option contracts. We characterize the optimal replenishment policy and show that it has a simple structure. Namely, the use of every different option contract and the spot market is dic...

摘要：We study the effect of financial risk on the economic evaluation of a project with capacity decisions. Capacity decisions have an important effect on the project's value through the up-front investment, the associated operating cost, and constraints on output. However, increased scale also affects the financial risk of the project through its effect on the operating leverage of the investment. Although it has long been recognized in the finance literature that operating leverage affects projec...

摘要：We consider the problem of managing demand risk in tactical supply chain planning for a particular global consumer electronics company. The company follows a deterministic replenishment-and-planning process despite considerable demand uncertainty. As a possible way to formally address uncertainty, we provide two risk measures, demand-at-risk (DaR) and inventory-at-risk (IaR) and two linear programming models to help manage demand uncertainty. The first model is deterministic and can be used to...

摘要：Recent empirical literature describes an industry's clockspeed as a measure of the evolutionary life cycle, which captures the dynamic nature of the industry. Among other factors, the rate of new product development is found to be associated with an industry's clockspeed. Yet the notion of an industry clockspeed and the essential factors driving suitable decision making in this area have remained relatively unexplored. We develop a simple definition and a corresponding analytic model which exp...

摘要：In this paper, we study the performance of a sourcing mechanism gaining popularity in industrial procurement environments; a tournament. Under a tournament, a buyer initially procures her parts from two suppliers with possibly different quality levels, for T time periods, i.e., she parallel sources. During this time, the buyer is able to observe noisy signals about the suppliers' quality. At time T, she selects the supplier with the highest observed performance and awards it the remainder of h...

摘要：W e study incentive issues that arise in semiconductor capacity planning and allocation. Motivated by our experience at a major U.S. semiconductor manufacturer, we model the capacity-allocation problem in a game-theoretic setting as follows: each product manager (PM) is responsible for a certain product line, while privately owning demand information through regular interaction with the customers. Capacity-allocation is carried out by the corporate headquarters (HQ), which allocates manufactur...

摘要：Business processes have become more simultaneous and collaborative in the recent past. In simultaneous processes, multiple parties must adapt to one another in real time as decisions evolve. For example, New Product Development (NPD) requires collaboration in the context of Concurrent Engineering, and Supply Chain Management (SCM) in the context of collaborative planning. In both cases, parties must modify decisions based on preliminary information, information that is not fully precise or sta...

摘要：A model is introduced to analyze the manufacturing-marketing interface for a firm in a high-tech industry that produces a series of high-volume products with short product life cycles on a single facility. The one-time strategic decision regarding the firm's investment in changeover flexibility establishes the link between market opportunities and manufacturing capabilities. Specifically, the optimal changeover flexibility decision is determined in the context of the firm's market entry strate...

摘要：This paper describes a structured methodology for decomposing the conceptual design problem in order to facilitate the design process and result in improved conceptual designs that better satisfy the original customer requirements. The axiomatic decomposition for conceptual design method combines Alexander's network partitioning formulation of the design problem with Suh's Independence Axiom. The axiomatic decomposition method uses a cross-domain approach in a House of Quality context to estim...
