A MULTI-CRITERIA DECISION-MAKING IDEAL INTERVAL METHOD FOR COMPREHENSIVE EVALUATION OF WATER ENVIRONMENT QUALITY
Abstract
The classic multi-criteria decision-making by ideal point approach is studied, since the water environment quality evaluation standard is regarded to be an interval concept rather than a point concept. The evaluation standard processing into ideal points has some flaws. A multi-criteria decision-making ideal interval technique (MCDMIIT) is developed to overcome this flaw. The MCDMIIT principle is introduced, along with its composition method and application to complete water environment evaluation. MCDMIIT is more efficient than projection pursuit model and neural network technique. MCDMIIT is more applicable than multi-criteria decision-making ideal point technique. MCDMIIT is commonly utilized in environmental quality assessment.
