The research and system development work described in this paper is aimed at overcoming some of the problems associated with the development of large, complex linear programming problems. The most overwhelming problem is that of size. It is not uncommon for large planning and policy analysis...

This paper describes the philosophy underlying the development of an intelligentsystem to assist in the formulation of large linear programs. The LPFORM system allowsusers to state their problem using a graphical rather than an algebraic representation.A major objective of the system is to...

Because of the difficulties often experienced in formulating andunderstanding large scale models, much current research is directedtowards developing systems to support the construction andunderstanding of management science models. This paper discusses sixdifferent methods for representing...
