Many countries have promoted energy efficiency and conservation in the residential sector due to its significant contribution to total demand. This paper discusses some of the wider implications of more efficient households on the overall energy system. Various efficiency options, such as...

Use of optimization models in science and policy applications is often problematic because the best available models are very inaccurate representations of the originating problems. Such is the case with electoral redistricting models, for which there exist no generally accepted measures of...

The Cournot model makes assumptions about the knowledge of the players, which can lead to counterintuitive results when extending the basic model. Closed-loop equilibria and models with consistent conjectural variations are problematic in that they reduce or eliminate economic rents while the...

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...

This paper describes some rules for combining component modelsinto complete linear programs. The objective is to lay thefoundations for systems that give users flexibility in designingnew models and reusing old ones, while at the same time,providing better documentation and better diagnostics...
