A new interactive multiobjective decision making technique, which is called the sequential proxy optimization technique (SPOT), has been proposed by the author. Using this technique, the preferred solution for the decision maker can be derived efficiently from among a Pareto optimal solution set by assessing his marginal rates of substitution and maximizing the local proxy preference functions sequentially.
In this paper, based on the algorithm of SPOT, a computer program for multiobjective decision making with interactive procedures is presented and called ISPOT. The program is especially designed to facilitate the interactive processes for computer-aided decision making. After a brief description of the theoretical framework of SPOT, the computer program ISPOT is presented. The commands in this program and major prompt messages are also explained. An illustrative numerical example for the interactive processes is demonstrated and numerous insights are obtained
