Model management systems: Design for decision support

Changes in computer technology have provided decision makers with the necessary tools for the design and implementation of computerized models for decision support. These models are frequently developed to solve a specific problem for a specific user and lack the flexibility and generalizability necessary to solve unstructured, strategic problems. In addition, problems of model redundancy, inconsistency, integrity and security have prompted an increased interest in the design of model management systems (MMS) that provide for centralized management of organizational models. This paper describes the use of a framework, developed by the authors, to design an MMS for support of planning decisions within an organization. The architecture of the MMS is described in detail and the rationale for the design decisions is presented.
