Abstract

Cyber-Physical Systems (CPS) form the new backbone of digital ecosystems. Upcoming CPS will be operated on a unifying basis, the Internet of Behaviors (IoB). It features autonomous while federated CPS architectures and requires corresponding behavior modeling for design and control. CPS design and control involves stakeholders in different roles with different expertise accessing behavior models, termed Digital twins. They mirror the physical CPS part and integrate it with the digital part. Representing role-specific behaviors and provided with automated execution capabilities Digital twins facilitate dynamic adaptation and (re-)configuration. This paper proposes to conceptualize agent-based design for behavior-based Digital twins through subject-oriented models. These models can be executed and, thus, increase the transparency at design and runtime. Patterns recognizing environmental factors and operation details facilitate the configuration of CPS. Subject-oriented runtime support enables dynamic adaptation and the federated use of CPS components.

Highlights

Agent Systems for Behavior-CenteredCyber-Physical System (CPS) are dynamic and complex systems, as their design involves a variety of disciplines, leading to contributions by various teams of engineers and experts with diverse backgrounds [1]
Behaviors%2C%20or%20IoB,Internet of Behaviors (IoB)%20commercial%20or%20government%20program), suggest a unifying behavioral approach to operation, the Internet-of-Behaviors (IoB), as a follow-up to the Internet-of-Things
Cyber-Physical Systems (CPS) development itself is highly heterogeneous, as it involves customers, employee, and design experiences considered to be critical amid distributed organizations

Summary

Introduction

Cyber-Physical System (CPS) are dynamic and complex systems, as their design involves a variety of disciplines, leading to contributions by various teams of engineers and experts with diverse backgrounds [1]. The reported list of modeling techniques and programming tools for designing CPSs include formal semantics approaches and architecture styles, such as (multi-)agent and event-based semantic models These models should feature intelligent composable (business) operations The diverse and dynamic nature of CPS requires introducing composable and executable digital twins as behavior models They are part of development that integrates the operating user/consumer into design processes and puts modeling as the center of CPS (development) practice. For the sake of effectiveness and accuracy, I primarily utilized the existing knowledge and experiences on the design-integrated engineering of behavior models (digital twins) for CPS development They stem from an agent-based system and business process development
