Electrical Maintenance

[blingbling4r]

I'm not sure if I posted in the right forum but I represent a local electrical contractor. We are trying to implement a electrical preventative maintenance program and part of that would include an extended warranty on our parts and labor. How would I go about pricing something like that using an actuarial basis? I don't even know where to start or what questions you guys need to help me out!

Cost of Repair i * Pr(Repair i) occuring? You can also introduce a discount factor for timing. Similar to life insurance I imagine.
