In the development of a new software solution, users and developers spend the majority of their effort on modeling the functional requirements. The Non-Functional Requirements (NFR) are treated as a second class requirement, ignored until the end of the development cycle. They are often hidden, overshadowed and therefore, frequently neglected or forgotten. They are neglected because NFRs are often...
The Belief-Desire-Intention (BDI) agent model is one of the more favoured models used to develop various agents due to both its flexibility and conceptual adaptability. This is mainly with regards to its ability to distinguish between a series of plans through a tailored plan selection function such that the plan most suitable to the current situation is selected. Since BDI agents were first proposed...
One of the challenging areas in dealing with Non-Functional Requirements (NFRs) is the need for a decision support system which helps in a better trade-off among alternative operationalizations in the potential solution space for the NFRs. Dealing with such a trade-off is popularly treated with a qualitative fashion through the NFRs framework. In this paper, we propose the incorporation of the mathematical...
In this paper we introduce a generic approach to analyze system design models with regard to the satisfaction of their Non-Functional Requirements (NFRs) to enable the evaluation of their NFRs' trade-offs. NFRs and their satisfaction become especially critical and deserve more attention in certain application domains such as real-time and embedded systems. This is mainly due to the constraints and...
the Problem Frames (PF) approach is a prospective tool for classifying, analyzing and structuring software development problems. However, it at current stage lacks a practical way to capture NFRs. This paper aims to extend the PF Approach for helping system analysts to capture non-functional requirements within the PF approach systematically. A new problem model and a model-guided process have been...
Due to the high proliferation of web services, selecting the best services from functional equivalent service providers have become a real challenge, where the quality of the services plays a crucial role. But quality is uncertain, therefore, several researchers have applied Fuzzy logic to address the imprecision of the quality of service (QoS) constraints. Furthermore, the service market is highly...
