| The dynamic fuzzy question has attracted the academic community universal attention, but so far the research results in this field both at domestic and foreign not to be many. Professor Fanzhang Li proposed the dynamic fuzzy sets and the first-order dynamic fuzzy logic system based on the theory of fuzzy sets and fuzzy logic which be proposed by L.A.Zadeh,and there has a series of foundation achievement about the dynamic fuzzy sets and the first-order dynamic fuzzy logic system.Therefore,this thesis attempts to further consummate the dynamic fuzzy logic system and promote dynamic fuzzy theory applied to the actual.The main contents include as follows:1.The spectrum analysis method of the dynamic fuzzy predicate logic is given.2.The second-order dynamic fuzzy logic is given based on the first-order dynamic fuzzy logic.3.The propositiona logic calculus and the predicate calculus inference system of the second-order dynamic fuzzy logic are given,and the semantic description of the second-order dynamic fuzzy logic is given.4.The spectral theory of the second-order dynamic fuzzy logic truth value domain is given.5.The reasoning model of the second-order dynamic fuzzy logic is given,which proposes a new model to do dynamic fuzzy logic reasoning based on incomplete information.6.An example system is given.Thus the application filed of second-order dynamic fuzzy logic is given.Through the work of this paper,it enriches the dynamic fuzzy logic system and the new reasoning model,and the theory of the second-order dynamic fuzzy logic have been proposed which proposes a new method to dealwith the dynamic fuzzy problem in real life. However,facing the unknown world there are many issues which need further exploration. |
