Shift Scheduling of Short Time Workers in Large-Scale Home Improvement Center by using Cooperative Evolution
Abstract
There are a lot of large-scale Home Improvement Center (HIC) in Japan. In the large-scale HIC,
about hundred short time workers are registered. And about forty workers are working every day. A manager
creates a monthly shift schedule. The manager selects the workers required for each working day, assigns the
working time and break time for each worker and also work placement. Because there are many requirements
for the scheduling, the scheduling consumes time costs and efforts. Therefore, we propose the technique to create
and optimize the schedule of the short time workers in order to reduce the burden of the manager. A cooperative
evolution is applied for generating and optimizing the shift schedule of short time worker. Several problems has
been found in carrying out this research. This paper proposes techniques to automatically create and optimize the
shift schedule of workers in large-scale HIC by using a Cooperative Evolution (CE), to solve the situation that
many workers concentrate in a speci c time zone, and to solve the situation where many breaks are concentrated
in a speci c break time zone, and an effective mutation operators.
