Fuzzy Solution of Uncertainty Problems in Multi-objective Optimization of Accelerated Degradation Test Design

摘要

How to obtain the most effective experimental data under limited resources via the optimal experimental design is one of main research topics of Accelerating Degradation Test (ADT). At present, the research on ADT design method mainly focuses on design randomness, while the design fuzziness hasn't been widely discussed but is another critical uncertainty to be addressed included in all aspects of experiment design. This paper is proposing an ADT optimal design methodology based on fuzzy theory, including methods of fuzzy objective and constraints determination, result assessment, and optimal design procedures. An engineering case about rubber seal ring ADT experimental design is provided to validate optimal design methodology to address fuzzy problem and enhance ADT design.
