Dynamic Pricing Strategies With Reference Effects: This paper considers the dynamic pricing problem of a monopolist firm in a market with repeated interactions, where demand is sensitive to the firm's pricing history. Consumers have memory and are prone to human decision making biases and cognitive limitations. As the firm manipulates prices, consumers form a reference price...; Tags: Pricing, Marketing research, pricing strategy, decision-making, theory, strategy; White papers 2006-02-01
A Conceptual Model for the Creation of Supply Chain Simulation Models: This paper presents the development of conceptual models that can be used in the creation of certain types of supply chain simulation projects. The supply chain considered is composed of four elements: suppliers, manufacturer, retailers, and the consumer market. The presented ideas can be used in supply chain simulation projects,...; Tags: Supply chain management (SCM), supply chain, supplier, collaboration; White papers 2005-11-08
Delegating Pricing Decisions in Competitive Markets With Symmetric and Asymmetric Information: This paper examines the issue of price delegation versus centralized pricing in the context of a competitive market.

Consumer Directed Health Care: Healthcare financing continues to be a significant problem in the United States. Healthcare costs are trending considerably above that of inflation. In 2002, the U.S. health care spending increased 9.3 percent - the largest increase in 11 years. It increased an additional 7.8 percent in 2003, raising total health care...; Tags: Vertical industries, Benefits, HEALTHCARE, health care, inflation, financing; White papers 2005-07-09
institute for operations research and the Management Sciences: This paper investigates the problem of planning marketing mix in dynamic competitive markets. The authors extend the Lanchester model by incorporating interaction effects, constructing the marketing-mix algorithm that yields marketing-mix plans with strategic foresight, and developing the continuous-discrete estimation method to calibrate dynamic models of oligopoly using market data. Both...; Tags: Tools & Techniques, Engineering, decision-making, algorithm, marketing; White papers 2005-03-04

Time-Varying Competition: Researchers typically assume that competitive intensity is invariant when the demand and cost conditions change. With this assumption, an increase in demand or cost will cause prices to increase. It introduces the notion of time-varying competition to the marketing literature by modeling the indirect effects of demand and cost variables...; Tags: Research & Development, modeling, marketing; White papers 2005-02-10
Analysis of a Borderless Fab Scenario in a Distributed Simulation Testbed: Distributed simulation based on the High Level Architecture standard is adopted to realize the simulation of a borderless fab that involves two wafer fabs located in close proximity. The two fabs pool together their resources for capacity sharing. To demonstrate the benefits of this concept, experiments were conducted to measure...; Tags: fab, analysis, benefit; White papers 2004-11-11
A Neutral Information Model for Simulating Machine Shop Operations: The objective of the paper is to apply a nested partitioning (NP) method and an optimal computing budget allocation (OCBA) method to reduce the computational load without the loss of the performance of multi-pass scheduling.
