PROMETHEE-Cloud: A web app to support multi-criteria decisions

Multi-Criteria Decision Analysis (MCDA) is a systematic approach to evaluating and prioritizing alternatives based on multiple, often conflicting, criteria. It integrates quantitative and qualitative data, expert judgment, and stakeholder input to support transparent and structured decision making. Recent advances in MCDA methodologies have been supported by the development of software tools that enhance their practical application. This paper presents PROMETHEE-Cloud, a web-based tool for applying the PROMETHEE methodologies. PROMETHEE-Cloud provides user-friendly interfaces for a range of functionalities such as sensitivity analysis, e.g., Monte Carlo simulations, Walking Weights, Insensitivity Intervals and supports the import/export of decision models. Furthermore, PROMETHEE-Cloud is used to evaluate sustainability measures for a container terminal. The results show the effectiveness of the tool in helping decision makers to identify and prioritize optimal solutions under multiple conflicting criteria.
