Version [1.1] - [MakeDecision: Online system for the graphical design of decision-making models in crisp and fuzzy environments]

Abstract

This paper presents an extension of the MakeDecision application, significantly enhancing its capabilities for addressing multi-criteria decision problems and designing structural decision-making models. The updated tool includes a wide range of new techniques that broaden the comprehensiveness of calculations, enabling the development of more complex and robust decision models. These additions include new Multi-Criteria Decision Analysis (MCDA) methods for both crisp and fuzzy environments, as well as new distance metrics, normalization techniques, defuzzification methods, and correlation coefficients. A novel data visualization module has also been integrated to facilitate the interpretation of results. Furthermore, the application allows for the adjustment of decision models with specific measures characteristic of selected MCDA methods, such as the preference function in the Preference Ranking Organization METHod for Enrichment of Evaluations (PROMETHEE) method, the compromise solution in the Characteristic Objects Method (COMET) method, and the expected solution point in the Stable Preference Ordering Towards Ideal Solution (SPOTIS) method. Enhanced validation procedures provide users with more detailed guidance, while the redesigned interface improves usability. This extension transforms MakeDecision from a simple decision model prototyping tool into a comprehensive workbench, enabling the creation and analysis of advanced structural decision-making models.
