Avaliação de transportadoras de materiais perigosos utilizando o método electre tri

Abstract

Neste trabalho apresenta-se uma metodologia para a classificação e escolha de prestadores de serviço para transporte de materiais perigosos, fundamentado na metodologia de Auxílio Multicritério à Decisão - AMD. A metodologia aqui proposta apresenta características que permitem considerar a subjetividade inerente ao processo de avaliação de desempenho dos Prestadores de Serviço, diferenciando-se, assim, de outros métodos de seleção de fornecedores de serviços de transportes. As particularidades da metodologia proposta, principalmente em relação à sua aplicabilidade, foram verificadas num caso em uma empresa distribuidora de combustíveis, com rede de postos em todo o Brasil.

Worker-Recovered Companies in Brazil: self-management process assessment by applying multi-criteria decision support tools

“…However, studies developed by Freitas et Costa (1998), Mansur et Costa (2000), Costa, Soares et de Oliveira (2004) and Costa, Mansur, Freitas et de Carvalho (2007) have shown MCDS potentiality for classifying services in an ordering scale, suggesting a position and class for each service.…”

“…This fact shows that the use of MCDM methodologies is more recom-mendable for addressing this kind of problem, when compared with the use of weighted average." (Mansur et Gomes, 2000) Although the studies already performed using this approach present good results with the use of these methods, Costa, Soares et de Oliveira (2004) mentioned that "the diffusion of the modeling of this kind of problem using such tools is not seen in the literature. "…”

“…In the De Borda method, the evaluation is done for each criterion, assigning each of them with a score related to their position in the criterion ranking. In the end, the scores assigned to each criterion are added and from that addition, a final ranking is generated (Costa, Soares et Oliveira, 2004).…”

“…We were inspired by the works of Costa, Mansur et Freitas (2007) and Costa, Soares et De Oliveira (2004), for elaborating these steps.…”

Organizational change in quality management aspects: a quantitative proposal for classification

“…It is based on the personal and environmental context in which the decision-maker is inserted. Therefore, different analysts may perceive the criteria in a different manner (Costa et al, 2004).…”
