“…CPS are said to be key in the management of big data and to ensure interconnectivity in manufacturing facilities (Lee et al 2015). Agent technologies in connection with the management of holonic manufacturing entities has been investigated by Wang and Haghighi (2016) who propose the use of such a software approach for the coordinated control of CPS systems within holonic manufacturing system.…”

Current OEM (Original Equipment Manufacturer) facilities tend to be highly integrated and are often situated on one site. While providing scale of production such centralisation may create barriers to the achievement of fully flexible, adaptable, and reconfigurable factories. The advent of Industry 4.0 opens up opportunities to address these barriers by decentralising information and decision-making in manufacturing systems through CPS (Cyber Physical Systems) use. This research presents a qualitative study that investigates the possibility of distributing information and decision-making logic into 'smart workpieces' which can actively participate in assembly operations. To validate the concept, a use-case demonstrator, corresponding to the assembly of a 'flat-pack' table, was explored. Assembly parts in the demonstrator, were equipped with computation, networking, and interaction capabilities. Ten participants were invited to evaluate the smart assembly method and compare its results to the traditional assembly method. The results showed that in its current configuration the smart assembly was slower. However, it made the assembly process more flexible, adaptable and reconfigurable.

“…Since there is no such thing as a dedicated Holonic programming language, most Holonic designs are transposed into agent or service based architectures or a combination of both in articulation with other technologies [26], [27], [28], [29]. A detailed discussion about the conceptual difference between Holons, Agents and Services is off-topic in this contribution and the interested reader can refer to [30], [31] for a comprehensive discussion.…”

Abstract-The concept of Industry 4.0, or the Fourth Industrial Revolution, has the potential for radically increased system reconfigurability and flexibility. At its core, the notion of CyberPhysical System, as the new generation of embedded systems with advanced artificial intelligence and improved communication capabilities, is seen as the key enabling concept that will render production activities more sustainable. The Cyber-physical conceptualization dramatically reduces the integration effort by virtually eliminating the need, time, and cost for reprogramming. However, there are still important challenges that need to be addressed before one can start to design Cyber-Physical Production Systems consistently. These intertwine and are not as easily solvable as the popular science descriptions may suggest. This work brings them forward and develops a critical comparative analysis between today's automation solutions and their potential cyber-physical counterparts. The analysis considers the technical and conceptual challenges that are included in the process of migrating today's, mostly bespoke, automation solutions to highly modularized, dynamic, and interactive cyber-physical production systems. In this context, the paper considers the interplay between form and function of industrial components, at the light of their cyber-physical formulation. At the same time, it addresses the system-level (de)composability and interaction design challenges that arise from the integration of modular cyber-physical production systems.

“…However, holons can expose additional important features that resemble the real behaviour of construction execution, i.e. they organize into holarchies, where a system of holons cooperate to achieve an overall goal while negotiating with their own objectives [10]. Hence, they can reliably simulate the behaviour of cooperating agents in construction sites and the dynamics in such distributed operating environments [11] even if parameters change during the work progress [12].…”

Ensuring high efficiency in construction through advanced planning techniques must be supported by the simulation of construction processes. In previous research, the potential for multi-agent based simulation to support the planning phase were successfully shown with regard to some typical construction tasks. Among the main benefits determined by this approach the following ones were reported: capability of simulating real-world processes and interaction among resources; powerful 3D visualization; optimal sizing of resources. However, those models are not easy to create, because of the absence of built-in blocks and the many relationships among single agents and between agents and context.In this paper we propose the application of a novel holonic system for construction management, which is a sub-category of multi-agent systems. It combines the high and predictable performance promised by hierarchical systems with the robustness against disturbances and the agility of heterarchical systems. Holons are self-contained, stable, intermediate forms, that can be used to create a bigger whole. By using holons, designers aim to create complex systems that can be reused and redesigned much more rapidly than standard multi-agent systems. The approach was applied to the optimal scheduling of bored piles construction. Hence, a holonic construction execution system for bored piles tasks was developed. The holonic architecture was designed so as to integrate the DMAS pattern for scheduling optimization through stigmergy. The results of this paper showed the easy reusability of our simulation sub-systems and the potentials in terms of automatic optimal planning of construction works.
