Extension and modification of anticipatory failure determination approach based on I-TRIZ

Abstract

Anticipatory failure determination, abbreviated as AFD, is qualitative risk analysis approach that is based on I-TRIZ, a Russian short form of theory of inventive problem solving. Although this approach comprises two methods, AFD-1 and AFD-2, which are methodically structured to capture failure scenario that has occurred or predict and reveal future failures that have not occurred respectively, it has shortcomings and weaknesses which are very important to address and eliminate. In this thesis, weaknesses and shortcomings of the approach are explored, AFD-1 and AFD-2 are modi ed, and new AFD method named AFD-3 is created. The two modi ed AFD methods and newly created AFD-3 are based on SIVAI-TRIZ which is extended form of I-TRIZ for solving inventive problem. The modi ed methods and newly created AFD-3 o er higher degree of exibility, e ectiveness, and empowerment to reveal, predict and capture system failure scenarios. SIVAITRIZ body of knowledge is realized by applying system design approach to risk analysis through embedding design structure matrix (DSM) and design matrix (DM) of axiomatic design on AFD methods to address AFD shortcomings and augment I-TRIZ body of knowledge.
