“…These parameters, whose values are between 0 and 1, are effectiveness indexes referring respectively to the highest level, intermediate levels and the lowest levels of a system's tree (see Figure 2.b). Once the cells' OEE values are determined according to [13] and [4], every subsystem's OTE values are obtained following the formulas in [14]. Afterwards, by means of the Event-Condition-Action (ECA) calculation model described in [4], the DST provides, for each iteration, a list of actions towards improvement of system's performance.…”

“…The diagnosis is based on the measurement of the effectiveness of every device intended as a unit of the system of systems. During simulations, an overall throughput effectiveness (OTE) metrics measures the subsystems' performances and drives refurbishment design for their enhancement [4]. In fact, suggestions, history and lessons learnt from the OTE evolutions are re-directed to a BIM model to support decision making for the improvement of the whole building performance and design.…”

In the wide facility management context, several processes such as operations, maintenance, retrofitting and renovations ensure that buildings comply with the principles of efficiency and cost-effectiveness. Besides ordinary operation, facility management is responsible for renovation of building facilities and long-term improvement of their performances. In such a scenario, the cyberphysical system (CPS) paradigm with holonic architecture, that will be reported in this paper, can successfully advice the operation management of buildings, as well as long-term refurbishment processes. Indeed and in analogy with the manufacturing field, the developed CPS exploits holons self-configuration and self-organization and overall throughput effectiveness (OTE) metrics, in order to detect the best corrective actions towards system improvements. As a consequence, suggestions and lessons learnt from the evaluation of building efficiency are redirected to the BIM model. Hence, the digital model acts not only as a repository of currently available equipment for operations management, but also as a repository of the history of the diagnoses that supports decision making during maintenance, retrofitting and renovation processes. As a matter of fact, the repeated detection of a specific issue, since not affected by operations management, should be read as an opportunity to act and enhance the capabilities of buildings components. According to this approach, an automatic real-time diagnosis method is tested in a test case consisting of a multi-use and large public building.

Building management systems monitor and control building performances in real-time. Most control systems, which have been developed in the last decade, achieve the required performances relying on a centralised and hierarchical framework. In the regular operation phase, these systems are usually able to efficiently reach their goals, whereas they often fail to stick to predetermined targets in the presence of unforeseen disturbances. As a matter of fact, traditional control systems suffer complex unforeseen scenarios that cannot be modelled by the analytics and knowledge integrated in these systems, because hierarchical systems strive to keep full control at any level. As an alternative, holonic management systems, which have been successfully applied in the manufacturing field, can tackle this type of drawbacks. The flexibility of their elementary units, the holons, makes it possible to avoid the rigid structure of hierarchical systems so as to respond quickly to disturbances and dynamically rearrange their structure. In this paper, a first holonic computing structure is developed for indoor comfort management in an office room. The structure developed can drive both the operation management phase and the mediumand long-term measurement of performances. The former is implemented by means of a sequence of specific minimum cost actions which is based on the overall throughput effectiveness (OTE) metrics. The latter exploits the same OTE metrics to suggest corrective and improvement actions. Finally, OTE diagnoses are redirected to a BIM model to support decision making for long-term improvement actions on the building facility.

In the wide context of facility management, several processes, such as operations, maintenance, retrofitting, and renovations, ensure that buildings comply with the principles of efficiency, cost-effectiveness, and indoor comfort. Apart from ordinary operation, facility management is responsible for the renovation of and long-term performance improvement of building facilities. In such a scenario, the cyber-physical system (CPS) paradigm with holonic architecture, which is the focus of this study, can successfully guide the operation management and longterm refurbishment processes of buildings. Analogous to the manufacturing field, the developed CPS maximizes holons' self-configuration and self-organization and overall throughput effectiveness metrics to detect the best corrective actions toward system improvements. Consequently, suggestions and lessons learned from the evaluation of building efficiency are redirected to the building information model. Hence, the digital model acts as a repository of currently available equipment for operations management and the history of diagnoses that support decision-making during the maintenance, retrofitting, and renovation processes. Evidently, the repeated detection of a specific issue, which is unaffected by operations management, should be considered an opportunity to act and enhance the performances of existing building components. Similar to a goods-producing industry, the building management system developed in this study applies the aforementioned methodology to provide services related to indoor comfort and building health. This approach indicates that a method for automatic real-time diagnosis is tested in a case study consisting of a multi-use and large public building. The current paper, which is an extended version of the one presented in the Creative Construction Conference 2018, deepens the decision support tool and the supervision policy. Moreover, the developed system is contextualized by providing an example of use case and highlighting the step forward in the field of smart buildings.
