A Model-Based Approach for the Design of Cyber-Physical Human Systems Emphasizing Human Concerns

摘要

A Cyber-Physical Human System (CPHS) comprises software, hardware and the human, allowing interactions between them. While such systems become more complex, it is crucial to consider the human factor during their design, addressing human concerns. In previous work, the authors attempted to translate human concerns into criticalities, e.g., design requirements depicting human concerns, restricting CPHS usage. Here, an approach is proposed, aiming to facilitate the designer of CPHSs to integrate criticalities into the design process. This enables a more efficient design. For this purpose, we introduce a model-based approach adopting Object Management Group (OMG) standards, such as Business Process Model and Notation (BPMN), and Systems Modeling Language (SysML), to explore CPHS design and identify discrete views, representing both human and system aspects. Moreover, we explore the applicability of the proposed approach in the design of a Remote Elderly Monitoring System (REMS), where it is essential for the human to become part of the system wearing medical sensors. The identification of human criticalities during REMS design enabled the designer to evaluate different configurations considering human concerns.
