Design and Implementation of a User-Friendly GUI for the Service of Multi-Criteria Choice Based on Linguistic Programming

This work is dedicated to the problem of development, design, and implementation of a user-friendly GUI for the service of multi-criteria choice. While solving this problem, the main obstacle and challenge is that all multiple criteria are be considered simultaneously even though they are usually conflicting and mutually exclusive. Thereby, the service should provide tools for decision-makers to come to the most optimal decision through the comparison of multidimensional vectors. Different graphical visualization tools can be used in order to support and help the decision maker in understanding similarities and differences between the alternatives and graphical illustration is a very important part of decision support systems that are used in solving multiple criteria decision-making problems. The visualization task is by no means important and complex because, on one hand, the graphics must be easy to comprehend and not too much information should be lost but, on the other hand, no extra unintentional information should be included. In this work, we analyze different ways of visualizing a small set of discrete alternatives graphically in the context of multiple criteria decision making and provide our own version of convenient and user-friendly graphical interface.
