Fuzzy synthesis decision of part processing feature process chain based on TFAHP
The decision-making problem in the process chain of part machining features mainly relies on the experience of process personnel due to the existence of many fuzzy factors,which reduces the quality and efficiency of process design and can not meet economic requirements.In response to the above issues,considering the economy of part processing,the main factors affecting the decision-making of part processing feature process chain were analyzed,and a fuzzy comprehensive decision-making method for part processing feature process chain based on triangular fuzzy analytic hierarchy process(TFAHP)was proposed.Firstly,TFAHP was used to construct a judgment matrix,and indicator weights were calculated based on likelihood.Then,the membership function between the influencing factors of the part machining feature process chain and its candidate set was constructed,the fuzzy comprehensive decision-making of the part machining feature process chain was completed.Finally,taking a certain axis type part as an example,eight-hole machining feature process chains that met the machining requirements were determined.Combining with the actual application of the enterprise,the economic and effectiveness of this method in the decision-making of part machining feature process chains were verified.The research results indicate that the P-value of scheme 8 is 1.0,which is the optimal machining feature process chain.The quantitative evaluation E-value of this method is 0.137,which is more economical compared to traditional methods and meets the usage needs.
