Use of local area networks within manufacturing systems

Proposals have recently been made within the computer industry to standardize local area computer networking hardware and, although such standards are primarily aimed at the office automation market, they will undoubtedly find many applications in distributed industrial control where a requirement for high speed reliable standardized digital communications also exists. A simple manufacturing cell will be described which demonstrates the advantage of distributed control by using an integrated communications network employing low cost twin axial cable. The individual cell element control systems are supervised by a single computer station providing both control and management information. It will also be shown how such techniques can be applied within industrial manufacturing systems by considering the use of computer networks within a process plant and for the integration of industrial robot systems.     

Advances in automation and control research in China

Automation is the utilization of control techniques together with other information technology to control industrial processes, reducing the need for human intervention. It plays a highly important role in social and economy as well as in daily life. Control theory is the theory of automation, and is an interdisciplinary branch of engineering and mathematics, examining the behavior of dynamical systems. China has a long history of manufacturing automatic devices. In recent years, some rapid progresses in control theory have been made in China. Many new theories and new methodologies have been developed to meet the increasing demands in industry, agriculture, defense, and other social sectors. Contemporary sciences such as complexity, systems biology, quantum technologies, have also found their close links to control theories and technologies. On the other hand, control theory itself has many unsolved fundamental problems requiring further studies and investigation. This paper is to review the development and progress that have been made in all these aspects in China. Some remarks on the future development of control theory are also presented.     

Effects of movement speed and predictability in human–robot collaboration

Human–robot collaboration (HRC) is characterized by a spatiotemporal overlap between the workspaces of the human and the robot and has become a viable option in manufacturing and other industries. However, for companies considering employing HRC it remains unclear how best to configure such a setup, because empirical evidence on human factors requirements remains inconclusive. As robots execute movements at high levels of automation, they adapt their speed and movement path to situational demands. This study therefore experimentally investigated the effects of movement speed and path predictability of an industrial collaborating robot on the human operator. Participants completed tasks together with a robot in an industrial workplace simulated in virtual reality. A lower level of predictability was associated with a loss in task performance, while faster movements resulted in higher‐rated values for task load and anxiety, indicating demands on the operator exceeding the optimum. Implications for productivity and safety and possible advancements in HRC workplaces are discussed.     

Design patterns for real-time distributed control system benchmarking

In this paper, we describe the design and development of a simulation–agent interface for real-time distributed control system benchmarking. This work is motivated by the need to test the feasibility of extending agent-based systems to the physical device level in manufacturing and other industrial automation systems. Our work focuses on the development of hybrid physical/simulation environment that can be used to perform tests at both the physical device level, as well as the planning and scheduling level of control. As part of this work, we have extended the proxy design pattern for this application. This paper focuses on the resulting software design pattern for distributed control system benchmarking and provides examples of its use in our hybrid physical/simulation environment.

Towards practical,high-level guidelines to promote company strategy for the use of reconfigurable manufacturing automation

Reconfigurable manufacturing systems (RMS) and more specifically reconfigurable manufacturing automation systems (RMAS) represent an industrial production paradigm that has evolved in the last twenty years, and provide a low cost solution in the presence of product variety. In spite of the potential impact of this approach to industrial competitiveness, the literature still lacks a set of structured guidelines, derived from the theory and from field studies, to promote its practical implementation in industry. In this paper some early results that contribute towards addressing this research gap are presented. A set of practical guidelines is derived and compiled from four sources: a literature review; a structured questionnaire survey on the attitude of industry to RMAS based on 55 respondents from various sectors of the manufacturing industry; unstructured interviews with the survey respondents to discuss the barriers to the implementation of RMAS; and lessons learned from three pilot industrial test cases where the feasibility of implementing a new RMAS was investigated. The portion of the work reported herein deals exclusively with high level and over-arching practical implementation aspects of RMAS, rather than detailed design and development aspects. The guidelines are validated through further feedback from industry.
