MOPEN: A computational package for linear multiobjective and goal programming problems

MOPEN is a computational package designed as a global tool for Linear Multiobjective and Goal Programming problems with continuous and/or integer variables. The main existing techniques for these problems have been included in this package. That is, it is possible to generate or approximate the efficient set using Generating Methods, to obtain Compromise solutions or to use Goal Programming or reference Point approaches. As will be described, many advanced options have been implemented with every method. MOPEN has been implemented under a Windows environment; thus, it is easy to build and handle the data entry files and the result layout files. The behavior of MOPEN – in terms of CPU time used to solve large problems – can be considered as good; therefore, this package is a powerful tool to handle the previously mentioned problems.
