A Calculation Method for the Availability of Series System Based on Monte-Carlo Method
Aiming at a class of large equipment series system with multiple units of the same type and multiple components,a calculation model of ship equipment system availability based on Monte-Carlo simulation method is proposed to consider the influ-ence of repairable spare parts number.By analyzing the configuration characteristics of the equipment system dimension,and the Markov state transition process of fault maintenance logic between the repairable parts and the spare parts is constructed in the com-ponent dimension,and the steady-state probability of its stable distribution is calculated.Finally,through numerical examples,the system availability under different spare parts schemes is obtained by analytical calculation and Monte-Carlo simulation methods.The correctness and effectiveness of the model are verified by comparing the simulation results with the analytical results.
