An Application Of Fuzzy Logic In The Risk Capital Decision

Fuzzy phenomena exsit in abundance all over,men can't obviate the question , following the technology on the upgrade.There are some scholars began to consider and study how to describe the ubiquitous fuzzy phenomena in objective world. For example the famous philosopher and mathematician--B · Russell. Professor Zadeh bring forward the Fuzzy theroy, but its development is uneven,because its traditional force makes a great handicap in West. On the contrary it receives a warm welcome in East. Now we know that fuzzy logic slam the door not precision but meaningless precision. It displaces infinitesimal fuzzy cost with immensity future, so the application of it is more and more extensive. Fuzzy logic is in the ascendant in science and commerce.And it becomes pop theme recently.Based on fuzzy logic theroy and model the thesis combines them with risk venture item decision, so it can be used to analyse and to study the factors which influence venture item. The application of fuzzy comprehensive evaluation can carry through comprehensively analyse some indeterminate factors in risk venture item decision, the analytic hierarchy process(AHP) is used to define the weight of different factors. The thesis comprises four chapters:Chapterl introduce the origin of fuzzy logic and its cognition on philosophyChapter 2 mainly introduce fuzzy logic basic knowledge and modelsChapter 3 By analysing finance risk venture decision ,we can undestand the characters and classes of finance risk venture decision .So it's the basis of the fuzzy logic evaluation method.Chapter4 By establishing risk venture item decision model,we can analyse and study concretely some unknowable or incertitude factors in risk venture decision.
