Statistical Process Monitoring for IoT-Enabled Cybermanufacturing: Opportunities and Challenges

Gray-box Soft Sensors in Process Industry: Current Practice, and Future Prospects in Era of Big Data

“…The WB modeling part of the GB will mostly remain the same; however, the data-driven part will be affected by the massive amount of process data. In this context, several studies have been reported on soft sensor design based on big data, i.e., taken from IoT sensors, [17][18][19][20][21]. Although these studies were based on BB soft sensors, they are summarized here to understand the additional tasks in developing the BB part of the GB soft sensors in the context of the big data.…”

“…He et al [18] developed an IoT-enabled manufacturing technology testbed (MTT) system based on temperature sensors. The sensing system comprised of 28 IoT temperature sensors attached to a CSTR plus corresponding data acquisition, transmission and storage systems.…”

“…In addition, the changes in the data-driven part of the GB models in the context of enormous amount of process data collected in Industry 4.0 are elaborated.Processes 2020, 8, 243 2 of 20 makes use of multi-sensory signals based on gyroscopes, accelerators, pressure, and magnetometers sensors. These sensors simultaneously do weather monitoring, step counting, screen orientation, gaming, etc.The use of smart sensors in the process industry has been demonstrated in several studies [17][18][19][20][21], where internet of things (IoT) devices are used to collect enormous amount of data from process equipment such hydraulic pumps, reactors, heat exchangers, etc. Considering the massive amount of data, data processing is performed before it is passed on for analysis and decision making regarding the process operations.The data processing methods have to handle the big volume, high frequency, variety and veracity of the data coming from the IoT devices [22,23].…”

Advanced Manufacturing Processes and Technologies

“…The adoption of IoT in manufacturing enables the transition of traditional manufacturing (Zhong et al, 2017b). Industrial IoT devices for manufacturing include sensors/actuators, computers with wireless networks, etc., which have contributed significantly to different aspects of manufacturing such as automation and tracking (He et al, 2017).
