“…In Bonci (2018c), an adaptation of the VSM leads to the cyber-physical viable system (CPVS). CPVS is a model that is designed to fill the gap between the new paradigm of CPS and the VSM framework, by establishing a continuum between humans and cybernetics.…”

“…A key to the effective implementation of the CPVS model is the holonic hierarchical view that constitutes the foundation of the HMT (Bonci, 2018c). A satisfying account on the many forms of holonic structures and interpretations in the management area can be found in Mella (2009).…”

“…Questionably, for highly deep trees of high degree, the complicatedness appears again if no automation of the HMT programming is obtainable (Bonci, 2018c;Bonci 2018f). Nonetheless, the HMT principle tends to use the as-simple-as-possible tree and starts with it, according to a lazy approach that refines the variety degree only when this is strictly needed, by plugging HMT in the context of a viable system approach (Bonci, 2018c;Badinelli et al, 2012), moreover, to make the level of precision of a control adjustable with each acquisition of new knowledge about the controlled system. Badinelli et al (2012) prescribe an adaptive, fuzzy-logic controller as a robust modeling tool for agents' epistemology and decision-making.…”

This paper presents the detailed definition of technique for the automation of the management of complex business systems, whether they are constituted of services and productions. The technique has been referred here for the first time as Holonic Management Tree (HMT) and has been consistently contextualized into undergoing research on technological frameworks for the management cybernetics, in which the concept of viable system represents a fundamental stance. HMT is based on the use of recursive formulas over self-similar holonic structures for the attainment of continuous performance improvement in a complex and continuously evolving process. The problem is associated to a recursive tree of self-similar structures of which in this paper we discuss the interpretation with respect to knowledge modeling domain. The basic expressions for the computation of the 2nd degree trees are provided and explained in detail by means of an example in lean management context. Moreover, this work presents and discusses the expressions that handle the implementation of the n-th degree case as a recurrent abstraction of the basic and simple 2nd degree computation.

Execution Time of Optimal Controls in Hard Real Time, a Minimal Execution Time Solution for Nonlinear SDRE

Many engineering fields, such as automotive, aerospace, and the emerging challenges towards industry 4.0, have to deal with Real-Time (RT) or Hard Real Time (HRT) systems, where temporal constraints must be fulfilled, to avoid critical behaviours or unacceptable system failures. For this reason, estimation of code's Worst-Case Execution Time (WCET) has received lots attention because in RT systems a fundamental requirement is to guarantee at least a temporal upper bound of the code execution for avoiding any drawbacks. However, until now there is no approved method to compute extremely tight WCET. Nowadays, indeed, HRT requirements are solved via hardware, using multi-cores embedded boards that allow the computation of the deterministic Execution Time (ET). The availability of these embedded architectures has encouraged the designers to look towards more computationally demanding optimal control techniques for RT scenarios, and to compare and analyze performances also evaluating a tight WCET. However, this area still lacks deep investigations. This paper has the intent of analysing results regarding the choice between three of the most established optimal controls (LQR, MPC, SDRE), providing the first link between WCET analysis and control algorithms performances. Moreover, this work shows how it is also possible to obtain a minimal ET solution for the nonlinear SDRE controller. The results might be useful for future implementations and for coping with Industry 4.0 emerging challenges. Furthermore, this approach can be useful in control system engineering field, especially in the design stage for RT or HRT systems, where temporal bounds have to be fulfilled jointly with all the other application's specifications.

“…It subscribes data deriving from Generic BS and is trained by real-time data published by the VRP. On the base of these data, the technology described in [15] and [16] is able to instantiate in real-time the Specific Plausible Plans for the emergency management of the considered building. As output, the most promising Specific Plausible Plan is detected (see Figure 1).…”

Emergency management can benefit from advanced information and communication technology (ICT), since it can support officers in charge of emergency management to deal with urgent decision within a really short deadline. Further enhancement can derive from the application of holonic systems, which typically deal with the unexpected. In fact, unexpected events may prevent the application of emergency plans, e. g. evacuation of people outside of a building in fire through a network of predetermined paths. The holonic emergency management system, proposed in this paper, guarantees the shift to a contingent approach, leveraging the flexibility and adaptability to changing scenarios deriving from the holonic theory. Last but not least, the BIM integration provides all the building's topological information. Such a technology can exploit general data to automatically detect unconventional ways out and arrange rescue operations in real-time. The developed system has been applied to the fire safety management of a large building in a university campus. The BIM model of the case study has been imported in a game environment where an unconventional pathfinding has been experienced.
