RELIABILITY DESIGN

• Scientifically allocate the reliability for the target product and subsystems, all the way down to their component and parts.
• Conduct failure modes, effects, and criticality analysis to identify areas, which should receive concentrated design, research, and development effort.
• Provide guidelines for critical reliability design reviews, manufacturing process and technique, quality control and human factors engineering practice.
• Optimize  the  reliability  goal  that  should  be  designed  into  products  andsystems for minimum total cost to own, operate, and maintain for their lifetime.

•  Evaluate the amount of redundancy to achieve the specified reliability.

•  Trade-off studies among reliability, maintainability, availability, cost, weight, volume, operability, serviceability, and maintain for their lifetime.

• Predict  at  the  design  stage,  the  reliability  being  designed  into  parts  and components via the stress/ strength interference approach and optimize reliability.
•  Provide the basis for comparing two or more designs and for choosing the best from the reliability point of view.
• Guiding corrective action decisions to minimize failure, reduce maintenance, and repair times and to eliminate over design as well as under design.
• Determine whether the changes made affected the life of the equipment in the right direction and to the desired degree.
• Prepare product reliability growth curves as a function of R&D, manufacturing, purchase quality, quality control, and testing
• Determine best test plan to evaluate and verify the reliability of products-
• Optimum sample quantity, and test time.
