Reliability Mandate: Optimizing the Use of Highly Reliable Parts, Materials, and Processes (PM&P) to Maximize System Component Reliability in the Life Cycle

摘要

Demonstration of required reliability performance levels prior to system fielding has remained a challenge for the Army, and in recent years, the success rate of systems achieving their stated reliability performance in operational tests has declined. Realization of required reliability performance necessitates effective management strategies and techniques in order to reduce risks. 'Designing-in' reliability tip front is one of the critical elements to insure adequate system level reliability. It has also been ranked as one the top reliability problems by Program Managers. One design technique for maximizing inherent reliability is through the use of highly reliable parts, materials, and processes. Reliable parts, materials, and process are the building blocks of the total system reliability. They also have a significant role in overall program success because of the contribution to cost, schedule and performance goals. This research concentrates on the impacts of highly reliable parts and materials on the overall reliability of a weapon system. To gather these data, the researcher drew directly from experiences of part, material, and process professionals from the Army, Navy, Air Force, and contractors with whom they interface. Results show that the key to success resides in early involvement of part, material, and process experts along with a process that facilitates communication and open dialogue. Maximizing inherent reliability is the desired end state.
