Desenvolvimento de plataforma SAM – Sistema de Análise Multicritério

Abstract

Multi-criteria decision-making in organizations presents significant challenges, especially when multiple experts with different preference formats need to evaluate complex alternatives. This work presents the development of SAM - Multi-Criteria Evaluation System, a web platform that facilitates group decision-making with heterogeneous information. The system was designed to address three types of decision problems: projects with weight criterion definition, singlecriterion projects with multiple alternatives, and multi-criteria decision-making with N criteria and M alternatives. The platform has two distinct interfaces: manager, responsible for configuring projects, criteria, alternatives and experts, in addition to accessing detailed reports; and expert, which allows project evaluation through five different methods: Scoring, Ranking, Resource Allocation, AHP (Analytic Hierarchy Process) and Cards. The system implements transformation functions to convert different preference formats into normalized weights, allowing the aggregation of heterogeneous evaluations and the calculation of consensus levels among experts. The results demonstrate that the platform offers a solution for group multicriteria decision-making problems, providing flexibility in choosing evaluation methods and generating detailed reports with consensus analysis to support managers in decision-making.
