Organizations may view outsourcing as a way to manage risk. We developed a decision-analytic approach to determine which risks the buyer can share or shift to vendors and which ones it should bear. We found that allocating risks incorrectly could increase costs dramatically. Between 1995 and 1998, we used this approach to develop the request for proposals (RFP) for the US Department of Energy’s (DOE’s) privatization initiative for the Hanford tank waste remediation system (TWRS). In the model, we used an assessment protocol to predict how vendors would react to proposed risk allocations in terms of their actions and their …

We present models for competition among multiple suppliers for demand from a single manufacturer. The suppliers produce to stock a single product and are allocated demand by the manufacturer based on the amount the amount of inventory they hold. We prove the existence of a Nash equilibrium for a broad class of market allocation schemes. For the special case of identical suppliers under either a stock-proportional or fill rate-proportional allocation, we show the uniqueness of the Nash equilibrium. Analysis of the Nash equilibrium for this case reveals that (a) the manufacturer benefits from competition (in the form of higher fill …

Managing Information Technology For Service Quality: A Study From The Other Side, Pratyush Bharati, Daniel Berg

System quality, information quality, user IS characteristics, employee IS performance and technical support are identified as important elements that influence service quality. A model interrelating these constructs is proposed. Data collected through a national survey of IS departments in electric utility firms was used to test the model using regression and path analysis methodology. The results suggest that system quality, information quality, user IS characteristics through their effects on employee IS performance influence service quality while technical support influences service quality directly. The results also suggest that employee IS performance contributes more to service quality as compared to technical support. …
Attribute-Based Differentiation Of Alternatives, Jeffrey Keisler
Attribute-Based Differentiation Of Alternatives, Jeffrey Keisler
Management Science and Information Systems Faculty Publication Series
An intermediate step is introduced to the decision dialogue process for decision analysis. Alternatives are refined after they have been generated within a strategy table but before they are subject to more detailed evaluation. Two or more judges create a subjective mapping from alternatives to attributes that will later be mapped to criteria. In strategy tables, each of the alternative strategies consists of a coherent set of choices made across several decisions that are to be coordinated. These strategic alternatives are modified so as to increase their differentiation in the attribute space, rather than in the decision space alone. When …

Combining Multi-Attribute Utility And Geographic Information For Boundary Decisions: An Application To Park Planning, Jeffrey Keisler, Ronald Sundell
Combining Multi-Attribute Utility And Geographic Information For Boundary Decisions: An Application To Park Planning, Jeffrey Keisler, Ronald Sundell
Management Science and Information Systems Faculty Publication Series
The quality and value of an area depend primarily on what is found within its designated boundaries. To determine the value of such areas in terms of boundaries, we have developed a methodology for integrating multi-attribute utility functions with spatial analysis so that desirable, or appropriate, boundaries can be determined on the basis of the goals and objectives for the park. The key to successful evaluation is the development of measures for what decision makers value, rather than merely using what is easily measured. In a detailed example for planning of national parks, the fundamental objectives are conservation and societal …
