Cost analysis of a system with partial failure mode and abnormal weather conditions

This paper deals with the cost analysis of a system having three modes (normal, partial failure and total failure) in two weather conditions—normal and stormy. Failure rates of the system and rates of change of weather conditions are constant while the repair rates are general. The repair time distribution depends upon the starting state of the repair and it does not alter with the change in weather. The system is observed at suitable regenerative epochs in order to obtain reliability characteristics of interest to system designers and operations managers. Earlier results are verified as particular cases.
