Watershed environmental planning through an inexact-fuzzy multiobjective programming approach

This paper presents application of an inexact-fuzzy multiobjective programming (IFMOP) method to a case study of environmental planning in the Lake Erhai Watershed. A number of socio-economic activities in the watershed were comprehensively designed through the IFMOP. The programming model was formulated based on analyzing complicated interrelationships among system components. Multiobjective and uncertain features were effectively handled by the integrated IFMOP technique. The interactive planning approach helped ensure desired compromise to be obtained. Several decision scenarios were generated and analyzed to provide different tradeoffs between various objectives while appropriate management practices were recommended for implementation. The results of the case study indicated that the IFMOP can provide a rational scientific base for the formulation of policies/strategies regarding regional socio-economic development and environmental protection.
