Reliability assessment framework for communication products based on environmental tests data

In this paper, a new framework of reliability assessment for communication products based on environmental tests data is given. First, a new index is presented to describe the ability to maintain steady performance under various environment conditions — Environmental Stability. Second, the statistical algorithm to calculate Environmental Stability is proposed based on performance index in environmental tests during development phase. Then, a standard procedure to generate a standard reference table of Environmental Stability is proposed in this paper, with a prediction of future outfield performance of different levels. With the help of Environmental Stability, it is possible to discover the weakness of products and provide evidence for future improvement with limited resources. At last, we have analyzed an application example of the proposed approach to verify its applicability and effectiveness. The analysis obtained with laboratory data is compared with actual outfield performance of the product.
