Decision support for siting problems
This article presents the results obtained in the implementation of a decision support system (DSS) applied to a specific siting problem: the location of installations for industrial waste management. The DSS is based on multicriteria decision analysis for the best siting of plants, optimising costs and environmental impacts. The proposed approach individuates a hierarchy of objectives, where at top-level a k-best solution of the problem of minimising a distance measure is computed, to reduce the space of alternatives. Specifically, the problem solved at top level has been mathematically formulated as a 0/1 fixed cost transportation problem (FCTP). This is an NP-hard combinatorial optimisation problem that can only be solved heuristically for real world problem sizes. A heuristic procedure is proposed that is nearly optimal for the data sets managed. Computational results both of the FCTP and of the whole systems are presented.
