UNV-Small
Table 5.15 and Figure 5.10 show the results for UNV-small. The overall matched is 47, which is better than expected for a small schedule. The average time taken is 0.39
seconds, which is very fast.

5.3.3 Overall Results and Analysis
The overall results show that the highest matching rate is LFR-medium followed by UNV-medium, UNV-large, and UNV-small respectively. This shows that the type of
schedule does not necessarily guarantee a match, but other factors like distribution and the relief period also influence the match. The reason why LFR-medium is the highest
is because the schedule has longer break periods so lateness can be absorbed. Unlike in large schedules, the relief period is just enough more or less than 50 minutes and gives
no chance for lateness absorption. The LFSO event is different because the time is

fixed; after sign-on the starting time is after 15 minutes. So the chance to reschedule depends on the size of the schedule. Table 5.16 shows that LFSO-large is 44.1,
LFSO-medium is 13, and LFSO-small 0. In the event of UNV, the factor depends on end work 2 and sign-off. In the medium schedule, there are different times for
signing off which is why UNV-medium is the highest 70.6. However, in large schedules, some crews have the same time for sign-off although their end work 2 is
different. This reduces the chances for a successful match UNV-Large is 66.6. Out of 4 events LFSO, LFR, LFSW, and UNV, the highest matched is UNV 66, 70.6,
and 46.9. The overall match is 42.1, which gives 2,805 successes out of 6,664 events. The result is good but still not satisfactory. There are many ways of increasing
the percentage matched, for example by building the schedule with characteristics that support rescheduling. The next chapter will explain more about this. The time is
different with different schedule types and nothing to do with different events. For large schedules, the average time is between 1.46 to 1.66 seconds, medium 0.77 to 0.9
seconds, and small 0.39 to 0.42 seconds. The time is quick and acceptable for a real- time scenario.
