Base operational unit corrective maintenance process modeling and simulation

To analyze base operational unit (BOU) corrective maintenance stratagem and accurately calculate fault recovery time, BOU corrective maintenance process simulation models among depots was set up, the models in depot was also set up according to system engineering modeling ideology, BOU corrective maintenance activities was described. Accumulate maintenance rate (AMR), maintenance mode rate (MMR) and remove rate (RR) parameters were presented. Measurement methods based on the parameters were given via to which BOU corrective maintenance process was quantitatively analyzed. The simulation algorithm was made out according to Monte Carlo simulation method. Theory and technology means were offered to equipment designer in the supportability design and analysis working areas. The corrective maintenance concept (CMC) was validated in an airplane individual unit example making use of simulation tests. The effects to support resource and maintenance time was analyzed with the bettered CMC.
