Framework for Managing System-of-Systems Ilities
نویسندگان
چکیده
The design of ilities in System-of-Systems (SoS) architecture is a key means to manage changes and uncertainties over the long life cycle of an SoS. While there is broad consensus on the importance of ilities, there is generally a lack of agreement on what they mean and a lack of clarity on how they can be engineered. This article presents the DSTA Framework for Managing SoS Ilities, which coherently relates key ilities identified as important for SoS architectural design. Newly established in January 2013 to guide Systems Architecting practitioners in DSTA, the framework also proposes a set of working definitions of key SoS ilities and introduces notions of how they could be measured.

A Framework for Incorporating “ilities” in Tradespace Studies
Non-traditional design criteria such as flexibility, robustness, survivability and others (collectively referred to as the “ilities”) are increasingly recognized as critical system properties for the success of aerospace programs. While most decision makers would agree that the ilities are important system properties, they are neither well-defined nor easily evaluated in isolation. While some e...
متن کاملMeasuring “ilities” is a Hopeless Task
Our society is at a turning point in the history of technology adoption, computer systems are creeping into the very fabric of everyday life. However, there is no overall framework for measuring many elements of systems, much less combining them into a system-level metrics for comparison or prediction purposes. Therefore, researchers propose the grand challenge of quantifying and measurement th...

متن کاملOn Using Ilities of Non-Functional Properties for Subsystems and Components
The use of ilities for systems engineering of subsystems and components is investigated. Prior work on ilities has emphasized or restricted their application to system level, non-functional properties. The premise of this work is that ilities can be applied with benefit, and in some cases out of necessity, to lower levels of systems as well. The veracity of this premise is established by provid...

Current commercial, civil, and military space architecture designs perform exquisitely and reliably. However, today’s architecture paradigms are also characterized by expensive launches, large and expensive high-performance spacecraft, long development cycles, and wide variations in ground architectures. While current assets provide high-quality services, and future assets are slated to improve...
