Abstract

This paper develops a stochastic fuzzy decision making method to solve a class of decision making problems which involve simultaneous uncertainty and ambiguity when screening water resources management alternatives. In these analyses, not only the performance value with respect to a specific criterion in a given alternative is uncertain, but also the performance implications of the given alternative may be vague with respect to the considered criterion by the decision maker. The integration between Monte-Carlo simulation and fuzzy decision making may provide a unique soft computing technique linking randomness and fuzziness together. Whereas the stochastic problem is mapped into a deterministic environment through the use of a Monte-Carlo simulation process, fuzzy decision making helps entail the linguistic uncertainty (i.e., ambiguity) in decision science. With this framework, the overall performance of a wealth of alternatives can be further evaluated, resulting in considerable reduction in the uncertainty and ambiguity in the decision making arena. Practical implementation has been assessed by a case study of the Sacramento-San Joaquin Delta in California in which the performance of four water export alternatives were evaluated to determine the satisfactory solution with respect to the environmental sustainability and cost-effectiveness criteria.
