Comprehensive evaluation is a scientific means to assess a complex system with multi-index. There are lots of synthetic assessment systems so far. Nevertheless, some of those are not convenient for being strait to special problems, or being flawed in theory. Fuzzy comprehensive evaluation is popular now, but in practice it sometimes resulted a problem: the classification is not distinct and the result is not rational. The article centered on the combination of attribute synthetic assessment system theory and its practical utilization, explicated the difference between attribute synthetic assessment system and Fuzzy comprehensive evaluation in theory, pointed out the defect of Fuzzy comprehensive evaluation and its reason.Attribute synthetic assessment system based on the concepts of attribute sets and attribute measure. The system consists of three subsystems: Sing index attribute measure analysis system, multiple index synthetic attribute measure analysis subsystem, recognition subsystem. It is an important procedure to decide the weight-value of index in practice. The means can be divided into two races. One is to value the weight of index objectively according to the data sets; the other may be subjectively based on special knowledge. The Attribute synthetic assessment system presented two models to state the weight of index .It defines the similar weight by similar figures, and gives a method of determining index weight according to an objective standard. Simultaneously it suggested the AHM to determine index weight subjectively based on special knowledge. The system presented an attribute hierarchy Model (AHM). AHM can't only be applied to decide the weight-value of index, but also can be used in classification and ranking according to a complex system with a hierarchic structure in practice.This paper utilized the attribute synthetic assessment system for atmospheric quality assessment, public place quality evaluation and hospital comprehensive quality assessment. (In example l,the thesis used similar weight, and in example 2 to 3, it exploited the AHM model.) By using computer, the algorithm of attribute synthetic assessment system is simple and easy to accomplish. The result is perfect. It revealed the system is scientific and effective.
