This paper describes the results of research, development and implementation of the Dynamic Interactive Network Analysis System (DINAS) which enables the solution of various multi-objective transshipment problems with facility location. DINAS utilizes an extension of the classical reference-point approach to handling multiple objectives. In this approach, the decision-maker (DM) forms his requirements in terms of aspiration and reservation levels, i.e., he specifies acceptable and required values for given objectives. For providing DINAS with solutions to single-objective problems, a special TRANSLOC solver was developed. It is based on the branch-and-bound scheme with a pioneering implementation of the simplex special ordered network (SON) algorithm with implicit representation of the VUB and SUB (variable and simple upper bound, respectively) constraints.

A pilot version of the system is implemented on …
