Abstract

AbstractOne important behavioral aspect of collaborative embedded systems (CESs) is their trustworthiness, which can be assessed at runtime by evaluating their software and system components virtually. The key idea behind trust evaluation at runtime is the assessment of system interactions and consideration of an extended set of actors that influence the dynamicity of these systems. In this sense, the behavior of collaborative embedded systems and collaborative system groups (CSGs) is part of a more complex behavior of digital ecosystems that form around the collaborating systems. One way of performing runtime virtual evaluation of such complex behavior is through the implementation of digital twins (DTs). DTs are executable models fed with real-time data that allow behavior to be observed and analyzed in concrete technical situations. The use of digital twins enables goals to be evaluated in holistic scenarios at three different levels: strategic level, tactical level, and operational level, as we present in this chapter.

Highlights

By considering the actors that interact directly and indirectly with collaborative embedded systems (CESs), the concept of collaborative embedded systems and collaborative system groups (CSGs) extends towards the notion of digital ecosystems
In the assessment of a digital ecosystem from the trust perspective, a trustor is the user of a service who can trust a trustee, who is the provider of the service, to satisfy its needs and expectations linked to a trustum, which is the service provided
In the model that we introduce in this paper, the quality of service (QoS) provided by a product has an impact on the health of the ecosystem

Summary

14.1 Introduction

By considering the actors that interact directly and indirectly with collaborative embedded systems (CESs), the concept of collaborative embedded systems and collaborative system groups (CSGs) extends towards the notion of digital ecosystems. 14.2 Building Trust through Digital Twin Evaluation return to the context of forming a vehicle platoon, where a system function sends context information that is inaccurate or even intentionally wrong, the tactical goal of the CESs to form an effective vehicle platoon will not be achieved. This has an impact on the strategic goal of reducing fuel consumption, with direct impact for the participants in a CSG. We use a similar hierarchy to structure the goals within an ecosystem by considering systems, system components, and actors
