Abstract
Desired system ilities, understood as lifecycle properties, generally drive the value of a system's architecture. However, ilities are hard to predict during system architecture development before the architecture has been instantiated with a system design. In this paper, an experimentation framework that can be employed to validate the adequacy of using architectural properties as proxies for ilities is presented. The experimentation framework builds upon a theoretical, generic conceptualization of ilities, which helps to formally justify the difficulties of and limitations in predicting how architectural choices influence system ilities. Application of the experimental framework is showcased with a notional scenario, where the framework is used to evaluate how different system topologies influence the integrability of a system.
期刊介绍：
Systems Engineering is a discipline whose responsibility it is to create and operate technologically enabled systems that satisfy stakeholder needs throughout their life cycle. Systems engineers reduce ambiguity by clearly defining stakeholder needs and customer requirements, they focus creativity by developing a system’s architecture and design and they manage the system’s complexity over time. Considerations taken into account by systems engineers include, among others, quality, cost and schedule, risk and opportunity under uncertainty, manufacturing and realization, performance and safety during operations, training and support, as well as disposal and recycling at the end of life. The journal welcomes original submissions in the field of Systems Engineering as defined above, but also encourages contributions that take an even broader perspective including the design and operation of systems-of-systems, the application of Systems Engineering to enterprises and complex socio-technical systems, the identification, selection and development of systems engineers as well as the evolution of systems and systems-of-systems over their entire lifecycle.
Systems Engineering integrates all the disciplines and specialty groups into a coordinated team effort forming a structured development process that proceeds from concept to realization to operation. Increasingly important topics in Systems Engineering include the role of executable languages and models of systems, the concurrent use of physical and virtual prototyping, as well as the deployment of agile processes. Systems Engineering considers both the business and the technical needs of all stakeholders with the goal of providing a quality product that meets the user needs. Systems Engineering may be applied not only to products and services in the private sector but also to public infrastructures and socio-technical systems whose precise boundaries are often challenging to define.
