A Study of State Management System in Manufacturing Processes using IoT

Abstract

In the market increased diversification and globalization, manufacturing companies are making efforts to improve their business operations to enhance competitiveness. Business management, such as visualizing and analyzing business operations, is indispensable in such activities. Also, management to support manufacturing activities requires the utilization of IT technology such as IoT. However, we could not find any concept and framework of an information system that is for management by using state of manufacturing processes based on domain concepts in a manufacturing company's activity area and cooperates with their existing equipment. Therefore, we propose an easy-to-reconfigure state management system by using IoT based loosely coupled software components. We aim to realize that users of the system can manage and improve their activities by using states defined by their specific concepts, and acquired and visualized from manufacturing tools they have. In this paper, we propose a state management system model, and then we describe a method and results that we have demonstrated the system by using some manufacturing tools at a real manufacturing factory. Furthermore, based on the results, we discuss the usefulness of the state management system.
