The method of attribute analysis in non-optimum to optimum

A theory corresponding to optimum systems,i.e.the non-optimum analysis of systems,is presented.Accocding to this theory,courses and results of mankind prcactice are classified by their nature into three categories:optimum,sub-optimum and non-optimum.The way of seeking the optimum system is found.Actually non-optimum systems not exclude pursuit of optimum targets and results in practice,and formation of non-optimums systems serves as the basis of existence of optimum systems.Besides,the various characteristics and functions of the optimum system can be measured from the non-optimum system.By summarizing the practical application,this paper also comes at the relationship between the optimum and non-optimum systems.According to the previous practice of optimization,a method is developed to approach the optimum from non-optimum.Research direction in this realm is finally put forward.
