Active events affection-based approach of zonal product multi-factors correlation analysis

Products arranged in the same zone usually have some spatial correlation, function relation and the impact of environmental stress, which usually causes coupling effect with other products in the same zone. This kind of coupling effect affects products' quality, and may influence the veracity and comprehensiveness of the quality analysis. To solve this issue, starting from changing the traditional characteristics-based analysis method, proceeding with the different type of zonal events, this paper proposes a logical decision method based on the active event to analyze the association effect between regional products, and obtains bad coupling on several important quality characteristics such as product function, reliability, maintainability, guarantee ability and testing. Also discover the impacts of the bad coupling on the specific quality characteristics. Through the most critical impact of the coupling events and the highest correlated products found by the logical decision-making process, it could use as a reference for improving the products design.
