Naturally, people introduced many useful achievements to this field. Since , who proposed to replace optimization plan with satisfactory one., After Simon’s theory, people turned to satisfactory degree, which made another brandnew knowledge system. Though satisfactory problems are mon to see, formalization and analysis of it are difficult because of lack of mathematical foundation. Satisfactory method is close to inspiring method rather than traditional mathematical reasoning. The purpose of this paper is to build up satisfactory functions in satisfactory problems systematically in order to find a proper satisfactory function which will be effective at any the beginning of several ways to define satisfactory degree,the paper bring up the forms of satisfactory functions and ways to build up them. On the basis of this,it leads to dynamic , sensitivity analysis is including in the final article which for provides a qualitative analys for the establishment of satisfaction function. Satisfactory theory is famous for its universality, fuzziness ,intelligence and relativity, which reflect humanity. The satisfactory theory includes theory of optimizaiton, inference engine , intellectual captune,artificial intelligence, pattern recognition, management Engineering and security. The design of satisfactory functions plays an important part in satisfactory optimization. This paper proposed several ways to define satisfactory functions under different occasions. It has done some work in popularizaiton of satisfactory optimization in our real life and satisfactory degree theory.
