Interfacing or models and information systems: A systematic approach

Abstract

Successful implementation of an OR model within an information system occurs only when the model becomes an integral part of the system. The process of incorporating a model into a system not only necessitates a detailed analysis of the model's informational requirements, which must be satisfied once the model is introduced into the system, but also requires an analysis of the information system with respect to these requirements. Such analyses may reveal that both the model and the system must be perturbed in order to effect a feasible interface. In determining the extent of the modifications to be made to each, the total cost of the various alternatives and the resulting effects on optimality must be established. This paper focuses on the development of informational models and procedures for performing these interface operations and the definition of a basis by which optimal or near optimal modifications and adjustments of the OR model and information system may be determined.
