Abstract:

Aiming at shortage of index identified and membership function selected in existing evaluation, a new method of fuzzy evaluation for design scheme base on information axiom is proposed. First, a zigzag mapping model is designed between target area and index area following the principle of axioms design and a comprehensive evaluation index system is established for product design scheme. Second, according to the different relations between index and design range, the evaluation indexes are divided into different types whose membership grade can be described by the normal fuzzy distribution curve. The calculation method is given for the corresponding information of index and can be applied in the scheme evaluation of the mechanical parking system. Last, the process of fuzzy evaluation is modeled based on information axiom.

Key words: fuzzy evaluation, information axiom, design scheme, membership function, mechanical parking system
