Abstract

Numerous reliability indices estimation of a system or component or element is very important in order to predict its availability and unavailability. Reliability is the specification which tells about the availability of the system under proper working conditions for a given period of time. Reliability of numerous complex engineering systems has been estimated in literature. In view of above, in this paper an innovational approach for estimation of various reliability indices such as failure rate, repair time and unavailability of a practical Hose Reel system is attained and different framework are evaluated. When an engineering system or device is in working condition, then there is a chance that the system or device fails and then a proper repair will be needed. The complete time period when the system or device is working is distributed in failure time and repair time respectively. A Hose Reel system is an engineering system which is developed in order to control the occurrence of fire and is a system which is used in emergency. As hose reel system is used in emergency condition, therefore proper working in the given time period is very important for the system and therefore there is a need for evaluating its various reliability indices. The unavailability of each and every component is evaluated. Component level failure rate, repair rate and unavailability were also estimated for the system. A practicable Hose Reel system put in place for the safety motive of the institute was considered for evaluating various indices.
