DINAS is an interactive system to aid solving various multiobjective transshipment problems with facility location using IBM-PC XT/AT or compatibles. DINAS utilizes the so-called aspiration-based (or reference point) approach to interactive handling of multiple objectives. In this approach the decision maker forms his/her requirements in terms of aspiration and reservation levels, i.e. specifies acceptable and required values for given objectives, whereas the system searches for a satisfying efficient solution by optimization of a special scalarizing achievement function. A sophisticated solver has been developed to provide DINAS with solutions to these single-objective problems. This numerical kernel of the system is, however, hidden from the user. Therefore the interactive analysis of the multiobjective problem can be performed with DINAS by a decision maker who is familiar with neither computer techniques nor mathematical programming.
