Patient scheduling in operating theatres (OT) involves high costs to hospitals and
may affect treatment and satisfaction to patients. Scheduling for patients in parallel
OT can help to schedule a large number of patients and emergency patients are
considered in this study .Other than that, emergency patients are able to be scheduled
and treated on the day as the modification of schedule is performed during the
dynamic processof scheduling. The objective of the study is to propose different
types of local search which are local search(LS), improved local search(ILS) and
mixed local search (MLS) for solving patient scheduling problem in parallel OT.
This study presents two phases of scheduling where initial schedule of regular patients is obtained in the first phase, then scheduling process continues in the second
phase when operations start and emergency patients arrive. In the first phase, pre-processing stage, combination of pre-processing stage with low-level heuristic and
genetic algorithm are used.The different types of LS are applied in the second phase
of scheduling. Tests are conducted for the proposed methods to look for a method
that has the ability to prevent delays of patients with a lower total cost. The performance of the LS is compared with zero-one programming method from literature
and it is reliable to the problem. The result of ILS has reduced the average total cost
to 30:4% while MLS has achieved 52:7% decrease in the average total cost. The
computational results show that MLS out performs both methods of LS and ILS by
minimizing the total cost of OT greatly. |
