An artificial intelligence approach to the formulation and maintenance of models
The complexity and the fuzzy nature of modeling have resulted in an increased need for providing support to modelers in the modeling process. This study is aimed at developing a computer-based system that supports naive users in the formulation and maintenance of optimization models, specifically: linear programming, quadratic programming, and integer programming models, in a production planning and distribution domain. A conceptual model of the formulation process was developed through concurrent verbal protocol analysis of several experienced modelers solving a variety of textbook and case problems. This conceptual model formed the basis of the modeling support system. The system was implemented in common lisp and Flavors, an object oriented language, and runs on a VAX 8600 system. Several users employed the system in a laboratory setting to formulate models for two problems. an analysis of the resultant models indicates that the users are able to formulate correct models with the help of the system even though they are unable to formulate these models on their own.
