Operational availability model of equipment in storage based on periodic inspection modelling

With regard to the problem of equipment operational readiness, the important parameter of operational availability is studied. The periodic inspection of equipment in storage is divided into perfect periodic inspection and imperfect periodic inspection from the point of view of whether the failure detection rate and the false alarm rate are considered. Considering factors such as test equipment, personnel and additional stress, models of operational availability in perfect and imperfect cases are discussed. Finally, according to the established model, the influences of fault detection rate and false alarm rate on the operational availability of storage equipment are analyzed theoretically and the behavior of the operational availability according to the time between checkouts is analyzed by setting the model parameter values. This model combines operational availability and reliability, maintainability, testability, etc. together, and provides a reference value for the subsequent improvement of equipment operational readiness.
