Synthetic Assessment System Based on Non-optimum Analysis Theory

Based on the theory of non-optimum analysis theory, Synthetic assessment system is studied. The system consists of three parts: single attribute analyses, multiple attribute analyses, selection analyses. Firstly, make use of the attribute set and attribute measure theory in attribute mathematics, optimum function, non-optimum function and sub-optimum function of objectives are structured, then the sub-optimum degree of each project can be calculated. Secondly, all alternative are ranked by sub-optimum value of projects and the optimal one is selected out. Finally, an application of the method to a case study indicates that the proposed method is effective and practical.
