Development of a Production Line Work Scheduling System Considering the Diversity of Work Styles

Abstract

In recent years, Japan's declining birthrate and aging population have become serious issues, and the working population continues to decline. As a result, companies find it difficult to recruit new workers and must maintain the number of workers by considering the request of existing workers. Therefore, we propose a system that can generate schedules in real-time to reduce the mutual burden of all people involved in schedule creation. In this paper, considering a manufacturing site with a mix of workers with different work hours, we propose a scheduling system that divides conditions corresponding to a wide variety of needs into objective functions and constraints, formulates each of them as a linear equation, and attributes them to the linear programming method. In this paper, we propose a system that can create schedules based on multiple constraints such as rest alternation, and load balancing. In this paper, we will conduct a scheduling experiment in a problem set based on real data provided by a food manufacturer where the majority of hourly workers. The practicality of the proposed system will be verified by comparing the generated schedules with the work records of the food manufacturer.
