Research And Application Of Human-computer Interactive System For Rational Allocation Of Regional Water Resources

Regional water resources allocation is a semi-structural decision-making issue. Since it has the characteristics of multi-layer, multi-object, multi-source, multi-user and multi-function, it cannot be solved by single model. Regional water resources allocation is involved in quite a few of practical problems, and need water users to participate in decision-making and water allocation, which is necessary for sustainable utilization of water resources. Establishment of an object-oriented and interactive decision-making supporting system is a better approach to solve these problems. In terms of water resources system, this paper presents the theory of multi-layer and multi-user interactive decision-making supporting system and its application.Theories and scientific research on development utilization and allocation of water resources in China and other countries are discussed and reviewed comprehensively in this study. Meanwhile, the connotation, feature, principle, object, scientific foundation for research and rational technical method of regional water resources allocation are also introduced.Due to the complexity of water resources system, a Geographic Information System (GIS) platform based on the Component Object Model (COM) is established in this study, and the rationality analysis and preprocessing of data are explored deeply. This paper presents a shared vision model that is applicable to multi decision-makers, and a human-computer interactive system for regional water resources allocation based on the technique of model base that is multi-object, multi-layer, multi-user and multi-decision making, since water resources system is semi-structural, ten indices which are representative independent and sensitive evaluation are selected, and the fuzzy comprehensive evaluation method is used to evaluate the performance of each allocation scheme.
