Accelerated Reliability/Durability Testing as a Key Factor for Accelerated Development and Improvement of Product/Process Reliability, Durability, and Maintainability

This paper demonstrates the results of the analysis of current situation in prediction of reliability, durability, quality, and maintainability; as well as results of development methodology and equipment for accelerated reliability testing which is a key factor in improving the current situation in the above areas. The implementation of 10 basic new concepts of this development decreases recalls, complaints, and total life-cycle cost of the product by at least 33% to 47%. This paper compares basic principles of new concepts with current ones. Practical accelerated reliability assurance for complex mobile systems and components based on multipurpose accelerated reliability testing (ART) is presented and illustrated. ART optimization and enhancement based on early reliability physics, systemic failure analysis and customized applied statistics covering various stages of R&D, manufacturing, and field service is justified and detailed. It provides further significant sustainable reliability growth associated with high customer satisfaction and dramatic reduction of expenses. Specific test and failure modes are substantiated covering various stages of R&D, manufacturing, and service. Recommendations are provided.
