Optimum Inspection Polic][es for a Standby Unit

An inspection policy for a standby unit is considered by taking a standby electric generator as an example. The expected cost by the time of the electric power supply failure is derived by rising renewal-type equations. We discuss an optimum checking time which minimizes the expected cost. We further obtain a checking time such that the probability that a standby generator has failed at the tim...

Optimum Lifetime Planning of Bridge Inspection and Repair Programs

This study proposes a general methodology for determining the optimal lifetime planning of bridge inspection and repair programs based on minimizing the ex­ pected cost while maintaining an acceptable level of reliability. For individual bridges, this methodology determines the optimum inspection technique. and the numbers and timing of inspections and repairs. The methodology is demonstrat­ ed...
