Linear Programming is an extremely powerful and widely used technique used in decision analysis. This paper describes the design, implementation and operation of an interactive, graphical linear programming software package implemented on a microcomputer. The software is written in Pascal and is supported by the UCSD Pascal Operating System. This operating system has allowed chaining between programs as well as extensive segmentation of procedures. The modularly implemented software package provides the user with the option of performing regular simplex and sensitivity analysis operations or graphical simplex and sensitivity analysis operations on a user-entered or preformatted linear programming problem. Should the user choose to perform regular simplex and sensitivity analysis operations on a problem, all results are displayed in tabular form on the screen. If the option chosen is graphical simplex and sensitivity analysis, the feasible region and simplex search procedure, as well as any changes to the objective function or feasible region as a result of sensitivity analysis, are displayed on the screen in high resolution, two-dimensional color graphics.
