A proposed approach supports the continual construction and evolution of model-based Internetware artifacts by a collective of Internet-connected stakeholders. The key mechanism is incremental graph superimposition (IGS), a refinement of stigmergy, the process that produces collective intelligence in social insects. Employing IGS, a collective of individuals collaboratively and continually construct...
Reasoning is critical for non-functional requirements (NFRs) analysis and verification. Furthermore, it can provide rationale about implementation strategies for NFRs. The existing tools can execute an interactive reasoning process which sometimes needs extra information from stakeholders. We build a tool called rΣ for reasoning on NFR models especially when extra information is unavailable or forbidden,...
Non-functional requirements are quality concerns of a software envisioned. As an effective treatment, goal-oriented method can capture NFR-related knowledge so that an evaluation for a specific implementation strategy can be provided. This paper makes a meaningful attempt to observe the implementation strategies of non-functional requirements in a probabilistic way, and obtain the probabilistic result...
Inconsistency is a pervasive issue in software engineering. Both general rules of inconsistency management and special case-based approaches to handling inconsistency have recently been considered. In this paper, we present a process model for handling requirements inconsistency within the viewpoints framework. In this process model, when an inconsistency among viewpoints is detected, a set of candidate...
We propose to integrate goal-oriented requirements language i* with concepts from problem frames (PF). The integration of goal and problem makes it possible to address designer's subjective intentions and the physical constraints from the environment at the same time. We illustrate the proposed approach with the meeting scheduler example
