Chapter Seven: Summary and Conclusions
7.1 Introduction
In this research, the literature gap that was found is that most of the current approaches to bus crew scheduling are concentrated on achieving optimum schedules, and they are
successful in finding optimum or near-optimum schedules. However, there is very little research considering minimizing the effect of UE problem on crew schedules. The
current researches that touch on the issue managing UE have limitations such as not being practical in real-world scenarios. In practice, bus companies manage UE
manually, which is hard and slow to make decisions, prone to error and not optimum. These limitations necessitate the need for an automated system that supports the process
of crew rescheduling to assist supervisors in dealing with UE problems that effect crew schedules. Therefore, as an attempt to cover the literature gap, this research proposed
the CRSMAS framework that uses MAS as a tool to automate the rescheduling process of crew rescheduling with the aim of minimizing the effect of UE upon crew schedules,
therefore reducing disruption to bus operation. To test CRSMAS we used two types of experiments, namely Single Event and Multiple Events. Based on the results it was
found that CRSMAS is capable of quick rescheduling but the success of the rescheduling is still low. Therefore some modifications to CRSMAS were proposed that

will make it more effective in achieving successful rescheduling. The work that was done on this research is still not enough fully to cover the literature gap. More research
is needed to cover the literature gap. This chapter concludes the research undertaken in this dissertation and recommends directions for further research. It begins with the
thesis summary, followed by the conclusions that were based on literature, interviews and experiments carried out. Limitations of this research are offered in the next section.
The final section provides recommendations for further research.
