In this paper, a fuzzy multiobjective mathematical programming model for operational transport planning in a supply chain is presented. The objectives of the proposed model are the minimization of the number of used trucks and the total inventory level, by considering vehicle capacities as a...

This paper presents a critical analysis of some of the techniques which are applied in practice to obtain composite indicators from a previous sub-indicator system. In studying each methodology, we identify the advantages and disadvantages associated with them, paying particular attention to...
