Study on crew diagram assignment for regular work environment with work shift operation

초록

In railway crew schedule planning, leveling of business hours between crew members is an difficult problem. Ensuring a regular working environment for crew members is also an important issue of scheduling. Unassigned crew diagrams, which occur due to errors in manual work, lack of manpower, etc., can cause additional problems in terms of working hours, such as uneven business hours and irregular working conditions. In this regard, this paper attempts to solve the problem of unassigned crew diagrams by dividing shifts and arranging crew diagrams first to calculate the minimum number of crews when preparing work schedules. In addition, a crew diagram considering the work type, with a period of 6 days, is arranged to ensure the regular working environment of the crew. In this process, an optimization algorithm is utilized to minimize the difference in business hours between the two shifts and to level the business hours between crews. ? 2020 The Korean Society for Railway.
