Default Preventive Maintenance time for a repairable system

How is preventive maintenance time for a repairable system decided given that repairable system does not follow a Weibull life distribution. RGA helps to determine number of failures that may occur over projected time for a repairable system. But how to combine RGA results with preventive cost and corrective costs to determine preventive maintenance time for a repairable system ? Please suggest references on methods and algorithms that explain preventive maintenance time for repairable systems.

Default Re: Preventive Maintenance time for a repairable system

The following link explains how RGA estimates an overhaul policy and the underlying assumptions.
http://www.weibull.com/hotwire/issue64/relbasics64.htm

If we are talking about preventive maintenance that partially renews the system, for example replacing a component preventatively, etc. an analysis at the component level may be required as well as the use of simulation. For an example see http://www.weibull.com/hotwire/issue78/hottopics78.htm.

Hope this helps,
Arai

Default Re: Preventive Maintenance time for a repairable system

Dear Mr. Arai.

I went through the link for RGA and from the example I used the equation no 5 to calculate the T0 using the shown parameters which are not matching. Kindly help me to understand which equation is used to arrive the optimum replacement time.

regards,

Asif
