GIEETP used to be scheduled manually in a 2-phase procedure. In order to approach the global optimum, this research presents a combined-coded genetic algorithm (GA) based scheduling method. This method includes two different types of chromosome encoding, real-valued encoding and permutation encoding. The first chromosome allocates timeslots for all subjects and avoids the mutual-exclusive constraints within subjects. The second chromosome arranges sequence for room allocation. In contrast to other exam timetabling problems, GIEETP emphasizes on the cost of total rooms used and the invigilators hired. The scheduling method is implemented in a software system, and real GIEETP data in recent years is taken as example to facilitate result comparisons. Results show that our method in general can obtain a solution more efficiently. |
