Weathering Server System Operations


In this paper reliability measures of a single-unit system operating under two weather conditions – normal and abnormal are evaluated using regenerative point technique. For this purpose, a reliability model is developed in which partial failure unit, fails totally. A single server randomly appears at partial failure of the unit on condition to visit immediately on complete failure of the system. The inspection of the unit at its partial failure is to assess the possibility of on-line repair. If not possible, it is repaired in down state. The repair of the unit at its complete failure is done without inspection. Server remains with the system in abnormal weather. The failure time of the unit and time of change of weather conditions are distributed exponentially; while the distributions of inspection and repair times are taken as arbitrary. Graphs are drawn to depict the behavior of some reliability and economic measures.
Keywords: Weather Conditions, Conditional Random Appearance of the Server, Inspection, On-line Repair, Partially Failure Stage (PFS), Reliability Measures.
