We present an overview of our approach to managing security as a dimension of Quality of Service. Relative to traditional QoS attributes (e.g., jitter, deadline, latency) security has been handled rather statically and indirectly. We have developed a theory of Quality of Security Service and a related security-costing framework that supports extension of QoSS functionality to embrace existing a...

Importanceeperformance analysis (IPA) is a popular customer-driven tool that enables companies to understand market competition and identify improvement priorities for various attributes of products and services. Despite the widespread use of IPA, previous studies have identified specific deficiencies. For example, the managerial improvement directions derived from IPA are potentially misleadin...

Timely adoption of new varieties is critical to profitable peach production, and peach quality is a primary factor driving adoption. An adoption model for peach varieties is estimated, incorporating grower evaluations of peach quality. The model identifies the impact of farm characteristics such as the farmer's quality preferences, on-farm agronomic and orchard conditions, as well as geographic...

This research focuses on developing a quality model for semantic Information System (IS) standards. A lot of semantic IS standards are available in different industries. Often these standards are developed by a dedicated organization. While these organizations have the goal of increasing interoperability, there is no way to determine the quality of such a standard. This research will provide qu...

We examine and bring out the architecturally significant characteristics of various virtualization and cloud oriented platforms. The impact of such characteristics on the ability of guest applications to achieve various quality attributes (QA) has also been determined by examining existing body of architecture knowledge. We observe from our findings that efficiency, resource elasticity and secu...

Software architecture is the result of a design effort aimed at ensuring a certain set of quality attributes. As we show, quality requirements are commonly specified in practice but are rarely validated using automated techniques. In this paper we analyze and classify commonly specified quality requirements after interviewing professionals and running a survey. We report on tools used to valida...

Most of the critical aspects for secure and dependable systems, such as safety, integrity, availability, are related to uncertainty. Literature proposes many approaches to deal with uncertainty, mainly in the area of risk management and safety&reliability engineering. However, what is still missing is a clear understanding of the nature of uncertainty that very often has produced mistreatments ...

This report examined the technical aspects of a future ecosystem-ready software platform for the smart building domain. We analyzed the type of contributors that may exist in a smart building ecosystem, the quality attributes that those roles are concerned with, and the key functional attributes that the software platforms of future smart buildings should provide in order to make smart building...

Architecture-based software development plays an important role in successfully developing and managing large and complex software systems. Recently, there have been a number of studies for designing, evaluating, or transforming architectures. However, there is not much work being done for closely connecting an architectural evaluation with an architectural transformation in order to achieve qu...
