RELIABILITY GROWTH MONITORING

PURPOSE

• To improve reliability overtime through changes in product design and in manufacturing process and procedure

• To provide continuous time oriented goals• It is a required task under government contracts.

• Selection of appropriate reliability growth equation is more art than a science

• Reliability growth cycle

ADVANTAGES

• These curves are used to monitor the progress of developed program.

• Used to identify product deficiencies and areas to be improved.

• To predict the time required to achieve a desirable reliability target.

GROWTH MODELS

• Idealized growth curve• Duane growth model• AMSAA model
