A DMS Cost/Benefit Decision Model: Cost and Preference Parameters

摘要

This report presents the general cost and preference parameters for the evaluation, comparison, and selection of data management alternatives. The parameters are derived systematically by using a hierarchical decomposition technique. The decomposition process starts with the basic categories of system requirements and terminates when sufficiently simple cost and preference parameters are derived based on which costs and preference measures of data management alternatives can be determined. The derived parameters are to be used by a quantitative analytic decision model for complex data management system evaluation and comparison. The role of the decision model in the system life cycle is discussed and the concept of system-requirement-based analysis of cost and preference analysis is introduced. An exhaustive list of parameters is accompanied by an appropriate description and justification for the existence of each parameter.
