Linear Program Solver (LiPS) is an optimization package intended for solving linear, integer and goal programming problems. The main features of the LiPS are: · LiPS solver is based on the efficient implementation of the modified simplex method; · LiPS provides not only an answer, but a detailed solution process as a sequence of simplex tables, so you can use it in studying (teaching) linear programming. · LiPS provides the procedures of sensitivity analysis, which enable us to study the behavior of the model when you change its parameters, including: analysis of changes in the right sides of constraints, analysis of changes in the coefficients of the objective function, the analysis of changes in the column / row of the technology matrix. Such information may be extremely useful in the practical application of LP models. · LiPS provides the methods of the goal programming, including the lexicographic and weighted GP methods. Goal programming methods are intended for solving multi-objective optimization problems. If you have any questions, feel free to contact me: Any comments and suggestions would be helpful! *** TROUBLESHOOTING *** If you cant get LiPS running install the following system updates: 1. Microsoft Visual C++ 2005 SP1 Redistributable Package - 2. Microsoft Visual C++ 2008 SP1 Redistributable Package (x86) - 3. Microsoft Visual C++ 2008 SP1 Redistributable Package (x64) - Michael Melnick, Department of Operations Research, State University of Management (Moscow, Russia)
