An implementation of a graph-based modeling system for structured modeling (GBMS/SM)
This paper describes GBMS/SM, a graph-based modeling system based on structured modeling that supports model formulation, maintenance and solution. Key features of GBMS/SM include the following: (1) model construction using graphical inputs, (2) modeling in multiple problem domains, (3) syntax-directed editing, (4) model views at different levels of detail, (5) automation of model data acquisition, and (6) interfaces to solvers, spreadsheets and databases. This paper presents design and implementation details of GBMS/SM that are of general interest to graphical modeling system designers. Challenges that were encountered in the development of GBMS/SM are emphasized in this paper.
