Representation schemes for linear programming models
Article Abstract:
A comparative analysis of eight approaches for representing linear programming problem at the formulation stage was undertaken. The methods examined fell into two categories, according to their underlying philosophy: symbolic and graphic. The symbolic representation schemes were matrix generators, algebraic languages and database oriented languages. The graphic representation schemes were structured modeling, block-schematic languages, activity graphs, netforms and iconic languages. The analysis found that the eight representation schemes were more or less equivalent considering the transformations that enable each scheme to change from one form to another. However, significant differences among these schemes were also found, particularly in the amount of work, skills and understanding that each scheme demands from its users.

A stochastic dynamic Nash game analysis of policies for managing the strategic petroleum reserves of consuming nations
Article Abstract:
Oil reserve build-up and draw down policies are basically the same, with or without international cooperation, since US and Foreign Strategic Petroleum Reserves have inventory limits. Oil inventory and tariff policy interactions for oil-importing nations are presented in a 'Nash' dynamic game model. The inventory policies are composed of rates for accumulating and reducing strategic oil supplies. Tariff policies are based on responding to the world oil market situation. The model offered is a stochastic exercise in which nations are grouped into two players, each of which selects individual policies to maximize expected social benefits.

Composition rules for building linear programming models from component models
Article Abstract:
A method for integrating component models into complete linear programs (LP) is described. It is hoped that this method will pave the way for the development of systems that will enhance the model management practices of users, as well as offer improved documentation and diagnostics. The method described involves constructing a complete algebraic statement of an LP problem out of that LP's component algebraic parts and integrating these parts into a whole LP matrix. This approach permits the combination of various problems and subproblems.
