水质模糊评价理论模式之研究

A Theoretical Model for Fuzzy Assessment of Water Quality

本文对水资源模糊评价理论进行了研究.简述了陈守煜的水质模糊评价理论模式,该公式是用最小二乘法原理建立目标函数,并用拉格朗日乘子法优化而成.本文利用权系数的概念推导出相似的新公式,具有概念清晰,推导简便的优点,比陈守煜公式更直观.本文还利用广义最小二乘法概念建立水质模糊评价模式的一般形式,更具普遍性,陈守煜公式和上述新公式只是它的一个特例,该公式可应用于一般模糊评价方法中.

An analytical model of fuzzy assessment of water quality is studied. Briefing Chen Shouyu's model, the model was established objective function by the least-squares principle and optimizing Lagrange multipliers. A similar form of fuzzy assessment of water quality is derived in a separate forthright way with a lucid conception. The form is directer than Chen Shou-yu's model . A general form of fuzzy assessment model of water quality is developed by the generalized least-squares. Chen Shouyu's model is spesial case. It's considered to be applicable to any fuzzy assessment method.
