Production Planning and Management Using Gantt Charts

In this paper, a support method for business planning and management using software is proposed in order to increase productivity in small and medium-sized industries. Our targets are job shop type production factories, which manufacture products that meet specific demands from numerous customers. For these factories to be successful, speedy operational planning and effective management of operations progress for different models in variable quantities are essential. Moreover, effective production and operations management needs to be promoted. Thus, it is necessary to obtain a tool that enables the maximization of throughput using a bird’s-eye view of the entire shop floor and understanding it from the viewpoint of optimization. In our study, planning production and expediting follow-up are conducted using Gantt charts. The system is a simple analog tool that heuristically supports production management through worksite knowledge and experiences without conventional approaches. Furthermore, robotic process automation (RPA) was introduced to reduce the workload of workers. The effectiveness of this prototype system was confirmed by a review of different people in charge.
