Table 3 shows the performance results under non-ideal maintenance and Figure 3 shows the maintenance schedule for non-ideal ABR and CBM. The results show that the inclusion of sudden failures now distorts the regular maintenance schedule under ABR. The average group size decreases to 1.63 and the total maintenance costs increase to 17.92 *CPM. In the parallel configuration, the efficiency is 98.35%, while blocking and starving decreases the efficiency in the serial configuration to 96.82%.
