Position paper
Essentials of Model-based Integration of Socio-technical Systems
Avi is the developer of the modern methodologies for utility-oriented systems engineering, integration engineering, and HSI engineering. The focus is on preventing operational errors. Avi proposes tutorials for developers of safety-critical, mission-critical, productivity-critical and consumer products, with examples from these domains.
Most accidents involving unexpected system behavior are commonly
attributed to errors. In analysis of case studies of well documented
accidents it was found that in many of them the root causes were
integration mistakes. It turns out that errors are also a key source
of productivity loss in operating office systems, and of failure to
operate communication and home applications. Review of the
integration literature reveals a need to develop guidelines for
integration design and testing. This tutorial presents an affordable
methodology developed in the last two decades, which offers
principles and methods for employing behavioral twins in model-based
integration design and testing.
The new methodology integrates methodologies of
interaction engineering, human-system integration (HSI) engineering,
human-centered design (HCD) and safety engineering.
The ultimate goal is to develop failure-free systems.
Root-cause analysis (RCA) of several case studies indicates a key
source for failure, which is under-disciplined coordination between
interacting processes. The new methodology
promotes reliable coordination. It integrates methods commonly
employed in leading industries with generic/universal
interaction rules, based on scenario-based modeling.
