ABSTRACT 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. INTRODUCTION There are many problems in engineering, that relate to reliability, maintainability, durability, quality, serviceability, etc., which remained unsolved until the present. One of the basic reasons for this situation is that until now people had not solved a fundamental) problem of accelerated reliability (durability) testing.They did not take into account that accelerated reliability/ durability testing (ART/ADT) is a key factor of accelerated development and improvement of quality, reliability, durability, maintainability, availability, and supportability through its accurate prediction during design, manufacturing, and usage. This paper is intended to acquaint the reader with the some aspects of the methodology and equipment needed to provide accelerated reliability/durability testing technology with the answer based on the question: HOW, which is very important for practical engineers, managers, and researchers, as well as teachers and graduate students. One can see this methodology in more detail in author's books [ 23], [ 28], [ 31] The paper demonstrates that the strategy for the above problems solution consists of the following interconnected steps [ 28]: • Accurate simulation of the complete field situation, which consists of three complexes: input influences, safety problems, and human factors; • Accelerated reliability/durability testing of the product/ process on the base the above simulation; • Accurate prediction during given time (warranty period, service life, etc.) of reliability interconnected with durability, maintainability, quality, availability, and supportability. This prediction one can do on the base of accelerated reliability/ durability testing results; Accelerated Reliability/Durability Testing as a Key Factor for Accelerated Development and Improvement of Product/Process Reliability, Durability, and Maintainability2010-01-0203 Published 04/12/2010 Lev M.

This paper also demonstrates the current state of the above problems and how they can be resolved through accelerated reliability (accelerated durability) testing.
