I have been assigned the task of creating general guidelines for introduciong new tools/equipment into a production environment. The vendors have done Developmental Verification and a successful Pilot run must be completed before they can be used company wide. My question is--- If I know R, C, b(weibull slope), MTTR, and sample size
a) is there a formula or methodology I can use to determine the proper Amount of cycles or run time that is needed to reach my desired reliability and confidence levels.
or
b)is there more information needed to determine this and if so, what is it
Unfortunately, I am not a reliability engineer and the last few weeks of research have given me a better understanding of what is needed, but I have reached a roadblock thx
