Multicriteria decision group model for the selection of suppliers

Abstract

Several authors have been studying group decision making over the years, which indicates how relevant it is. This paper presents a multicriteria group decision model based on ELECTRE IV and VIP Analysis methods, to those cases where there is great divergence among the decision makers. This model includes two stages. In the first, the ELECTRE IV method is applied and a collective criteria ranking is obtained. In the second, using criteria ranking, VIP Analysis is applied and the alternatives are selected. To illustrate the model, a numerical application in the context of the selection of suppliers in project management is used. The suppliers that form part of the project team have a crucial role in project management. They are involved in a network of connected activities that can jeopardize the success of the project, if they are not undertaken in an appropriate way. The question tackled is how to select service suppliers for a project on behalf of an enterprise that assists the multiple objectives of the decision-makers.Keywords: group decision; selection of suppliers; ELECTRE IV; VIP Analysis. ResumoVários autores têm estudado decisão em grupo nos últimos anos, o que indica a relevância do assunto. Esse artigo apresenta um modelo multicritério de decisão em grupo baseado nos métodos ELECTRE IV e VIP Analysis, adequado aos casos em que se tem uma grande divergência entre os decisores. Esse modelo é composto por dois estágios. No primeiro, o método ELECTRE IV é aplicado e uma ordenação dos critérios é obtida. No próximo estágio, com a ordenação dos critérios, o método VIP Analysis é aplicado e as alternativas são selecionadas. Para ilustrar o modelo, uma aplicação numérica no contexto da seleção de fornecedores em projetos é realizada. Os fornecedores que fazem parte da equipe do projeto têm um papel fundamental no gerenciamento de projetos. Eles estão envolvidos em uma rede de atividades conectadas que, caso não sejam executadas de forma apropriada, podem colocar em risco o sucesso do projeto. A questão colocada é como selecionar fornecedores de serviço para um projeto de uma empresa considerando os objetivos dos decisores envolvidos.

ELECTRE: A comprehensive literature review on methodologies and applications

“…Finally an overall ranking was obtained through an ELECTRE IV analysis. The numerical example was derived from data used by Alencar and de Almeida (2008), who presented a group decision model based on ELECTRE IV and VIP analysis and applied it for a contractor selection problem. considered a problem where a company acting as a master contractor must choose from a number of sub-contractors.…”

Selecting subcontractors in projects using a multicriteria group decision model

“…In this paper, the model used [8] covers two multicriteria methods: Variable Interdependent Parameter (VIP) Analysis [9] and ELECTRE IV [10].…”

“…-Multi-criteria group decision model In this stage, the multicriteria group decision model [8] (Figure 2) is applied using the bid winners criteria. The decision-makers are two engineers from the contractor company and one client representative.…”

A Group Decision-Making Aggregation Model for Contractor Selection in Large Scale Construction Projects Based on Two-Stage Partial Least Squares (PLS) Path Modeling

“…In addition, the application of group decision making in outsourcing contracts selection (Almeida 2007), selecting repair Contracts (Brito et al 2010), and selecting project team members and suppliers (Dempsey 1978;Alencar and Almeida 2008;) has been conducted, its application in the area of large scale construction projects needs to be developed, though.…”
