Abstract

This paper is one of the series of 11 Working Papers presenting the software for interactive decision support and software tools for developing decision support systems. These products constitute the outcome of the contracted study agreement between the System and Decision Sciences Program at IIASA and several Polish scientific institutions. The theoretical part of these results is presented in the IIASA Working Paper WP-88-071 entitled "Theory, Software and Testing Examples in Decision Support Systems" which contains the theoretical and methodological backgrounds of the software systems developed within the project.

This paper presents the PC-POSTAN package. This package constitutes a tool for postoptimal analysis for linear and linear-fractional programming problems. Contrary to the POSTAN 3 package it has been designed to be used on the IBM-PC computers running under the MS-DOS operating system. This is an interactive package which retains all options of the POSTAN 3 and adds some new features. PC-POSTAN consists of a number of FORTRAN routines which are incorporated into MINOS, the well known linear and nonlinear programming code developed at the Stanford University. The postoptimal analysis is performed after MINOS has found an optimal solution and is initiated by extending the original MINOS specification file. The main function of PC-POSTAN is ranging with respect to parameters specified by the user and computing the sensitivity coefficients. The user can control the program interactively, using hierarchical menu system. It is possible to perform series of experiments, selective inspection of results using the window interface, and modification of model data. For details regarding theoretical backgrounds of this package, the user is advised to consult the POSTAN 3 manual.
