지하철 기관사의 근무스케줄 최적화 방안 연구

A subway with its several positive characteristics such as safety, speed, and timeliness has made it to take a pivotal role in urban transportation. However it can cause a severe damage in case of disruption in train services. Owing to their vulnerable work conditions, that is, routinized working alone in a closed space, based on the irregular work and commuting schedule, the drivers are always suffering from the burden of safe running, which could not only cause them severe physical as well as mental fatigue, but also feel difficulties in maintaining a steady circadian biorhythm. Even though continued studies on systematic factors have been conducted for the safe operation of subways, the researches for the optimization of roster scheduling of subway drivers are so rare. The main purpose of this study is to depict the critical factors described above, and to suggest some effective alternatives to solve the problems, focusing on the computerized system for the optimum labor scheduling.
