AN INTERACTIVE INEXACT-FUZZY APPROACH FOR MULTIOBJECTIVE PLANNING OF WATER-RESOURCE SYSTEMS

In this study, an inexact fuzzy multiobjective programming (IFMOP) met hod is developed and applied to a case study of water pollution contro l planning in the Lake Erhai Basin. The IFMOP improves upon the existi ng multiobjective programming methods with advantages in data availabi lity, solution algorithm, computational requirement and result interpr etation. The case study project was supported by the United Nations En vironment Programme (UNEP). The results indicate that desired schemes for a number of system activities in different subareas/periods were o btained. Inheriting uncertain natures of the model inputs, the majorit y of solutions present as inexact values which provide decision-makers with a flexible decision space. Generally, the modeling results would provide scientific bases for the formulation of policies/strategies r egarding regional socio-economic development and environmental protect ion. (C) 1997 IAWQ.
