Reliability Prediction Method of Ship Supplies Receive System Based on Flow Simulation

Aiming at the calculation of time for receiving the ship supplies,the consideration of equipment failures is added,and the calculation problem is converted to by introducing the concept of receive time reliability. To solve the problem of reliability prediction,system reliability prediction method based on flow simulation is proposed. Firstly,the work flow of supplies receive system is analyzed. Secondly,the simulation of the work flow is achieved. Finally,the reliability of supplies receive system is solved by Monte Carlo method,and the influence of different reliability levels of equipment to supplies receive system. The simulation results indicate that the assessment of supplies receiving time is closer to the actual after the equipment failures is considered. The model of the reliability prediction method based on flow simulation is easier to understand and the conclusion is more specific.
