Primary vs. secondary decision making: a proposed expansion of model management systems research

Discusses the evolution of the use of models in DSS (decision support systems) and reviews work to date on the development of model management systems. In any but the most narrow DSS, model integration and model interactions necessitate determining the optimal scope of individual solution techniques and of the overall DSS. The authors identify several broad areas in model selection and integration which need to be addressed in future model management systems research especially DSS scope determination. A detailed example is included to help illustrate the research issues and problems discussed in the earlier sections
