A Multi-criteria Decision Support System for Supplier Selection

Decision Engineering, 2015

In this sense, all aspects that contribute to the competitiveness of a good or service must be considered during the selection of suppliers; these aspects include price, quality, lead time, etc. Therefore, the management of the supply chain should ensure a structured procedure for selecting its suppliers, in which a multi-criteria analysis approach is effectively considered during the selection. This chapter presents a multi-criteria decision support system for selecting suppliers; the system is divided into three main parts: (i) a structural phase, in which the parameters of the model are defined; (ii) the application of the multi-criteria method, in which the multi-criteria method PROMETHEE II is applied to construct a ranking of suppliers according to the parameters defined in the previous step; and (iii) the analysis of the results, in which a sensitivity analysis is performed to verify the robustness of the results. Also, in this chapter, this system was applied to a problem in the civil construction industry and shows that the proposed decision support system is a powerful tool to be used by any organization to support their supplier selection processes. The system assures an evaluation of suppliers based on a set of aspects that are important with regard to the purchasing of a good; also, the decision support system encourages impartiality during the selection and improves the transparency of the process, which indicates that the system is appropriate to support the selection process that occurs in public organizations.

A group decision-making approach using a method for constructing a linguistic scale

The use of linguistic expressions in voting makes the evaluation process friendlier, enables the intensity of preference in a decision maker's preference structure to be taken into account, and better captures the subjective information and intrinsic uncertainties that are inherent in human judgments. The quality of the decision will depend on the quality of the information obtained from the linguistic terms and expressions used in the evaluations, the semantic values of which should be representative of how decision makers interpret these within the context in which the language is being applied. The group decision-making approach proposed includes a method for constructing a linguistic scale in which the individuals and the decision context are inserted into the modeling process to determine the mathematical meaning of the terms used in the scale. The approach also includes a voting procedure based on the linguistic scale that was constructed for a specific group and context. The approach is appropriate for supporting decisions with heterogeneous groups, such as decisions involving society in general, because it provides a simple, complete and transparent way for assessing the alternatives.
