“…In this section, we present the conceptual model we developed for performing a governance-based analysis of autonomy levels for CPSs within CPSoS. This model builds on our previous work [4], and extends it with concepts for modeling governance within CPSoS. The meta-model of our conceptual model is shown in Figure 2, where we can identify a CPSoS that integrates CPSs.…”

“…In a previous work [4], we advocated that coordination among CPSs can be achieved by adjusting the autonomy level of some CPSs in a way that allows them to perform their activities without endangering other CPSs that are operating in the same environment. Although several researchers have suggested adjusting the autonomy level of a system based on various criteria such as its capability, motivations, behavior, etc.…”

“…[5]. We proposed to determine the autonomy level of a CPS based on its Awareness concerning its operational environment as well as its capability to safely perform its activity (e.g., Controllability) [4]. Based on these criteria, a CPS can have full, partial or limited autonomy for performing a specific activity.…”

One of the main challenges in integrating Cyber-Physical System-of-Systems (CPSoS) to function as a single unified system is the autonomy of its Cyber-Physical Systems (CPSs), which may lead to lack of coordination among CPSs and results in various kinds of conflicts. We advocate that to efficiently integrate CPSs within the CPSoS, we may need to adjust the autonomy of some CPSs in a way that allows them to coordinate their activities to avoid any potential conflict among one another. To achieve that, we need to incorporate the notion of governance within the design of CPSoS, which defines rules that can be used for clearly specifying who and how can adjust the autonomy of a CPS. In this paper, we try to tackle this problem by proposing a new conceptual model that can be used for performing a governance-based analysis of autonomy for CPSs within CPSoS. We illustrate the utility of the model with an example from the automotive domain.

“…The approach offers a conceptual model and a UML profile for modeling the autonomy levels of CPSs, and it also proposes constraints expressed in Object Constraint Language (OCL) 9 for the verification of such models. In this paper, we initially build on 4 but we bring significant updates and additional contributions. The most notable novel contributions are that i) we refine the conceptual model with an augmented categorization of autonomy concepts, ii) we consequently adjust the UML profile and we re-design its application to a use case on autonomous driving, and ii) we implement such use case in a simulator, namely the Carla simulator 44 .…”

A Cyber-Physical System-of-Systems (CPSoS) can be defined as a System-of-Systems (SoS), composed of a number of operable and autonomous Constituent Systems (CSs) that are themselves Cyber-Physical Systems (CPSs). A main challenge in integrating CPSoS to function as a single integrated system is the autonomy of its components, which may result in conflicts due to the lack of coordination among its CPSs. In this paper, we advocate that in order to facilitate the integration of CPSs within the overall context of their CPSoS, we may need to adjust their level of autonomy in a way that enables them to coordinate their activities to avoid any conflict among one another. Reducing such conflicts surely contributes to the dependability of the CPSoS. In particular, we propose a novel modelbased approach for modeling and analyzing the autonomy levels of CPSs based on their awareness concerning their operational environment as well as their capability to react in a timely and safe manner while performing their activity. The model is further described in a UML profile and applied to represent activities for autonomous driving scenarios. Using a driving simulator, we implement such models on a target vehicle and we show the resulting safety improvement, especially in terms of reduced collisions.
