Architecture for Multi-criticality Agile Dependable
Evolutionary Open System-of-Systems
The goal of AMADEOS is to establish a sound conceptual basis and a generic architectural framework
that address the challenges of guaranteed responsiveness, evolvability, dynamicity and emergence in
Systems-of-Systems. AMADEOS will provide basic concepts, measurable quality attributes, and propose
a design methodology, supported by extended mainstream UML-based tools, for the representation,
modelling, development, evolution and validation of Systems-of-Systems.

Introducing explicit, global, synchronized time into System-of-Systems
models. With such an approach, each
constituent system, interface and element has access to a precise, synchronized global time base.
Objectives
Capturing and formalizing System-of-Systems evolvability and dynamicity. Evolution is necessary for
the adaptation to environmental
changes such as new business cases, legal requirements, compliance,
changing safety regulations, evolving environmental protection rules,
etc. On the other hand unforeseen
events can occur, such as a disaster
or a failure of a constituent system.
Managing emerging properties in
Systems-of-Systems. Emerging properties and emerging behaviour in
a SoS may be either desired or undesired. Understanding the mechanisms of emergence will help in the
composition of constituent systems,
especially in predicting the effects of
composition on dependability, safety, security and availability.

Time Management Dependency on time is increasing in business

Development of UML modelling profiles and tool-extensions supporting the design methodology, and handling dynamicity, evolvability, emergence.
Evolution This requirements are based on the increased usage of
both EV charging and smart homes in the future.
Dynamicity This is related to the changing of built-in structure. Indeed, the offered services of the SoS considered in our case studies
remain constant over its interval of disclosure.
Multi-Criticality This is a characteristic of complex SoSs. Each of the
systems constituting the SoS provides services, each with its own
level of criticality, such as safety or security levels.
