ABSTRACT
We will define the Reliability Associated Cost (RAC) as the total cost incurred by the user in operation and maintenance of the system during its lifetime. In that case RAC will comprise the operating cost, repair cost and the penalty cost accumulated during the system lifespan. Therefore,
RAC = OC + RC + PC (1)
where
– OC is the system operating cost accumulated during the system lifetime;
– RC is the repair cost incurred by the user in operating and maintaining the system during its lifetime;
– PC is a penalty cost, accumulated during system life time, which was paid when the system failed.
