Requirement Uncertainty Analysis for Service-Oriented Self-Adaptation Software

While a few techniques have been developed to support the modeling and analysis of requirements for self-adaptive systems, limited attention has been paid to the description of service requirements and uncertainty in requirements of SoSAS. In this paper. we discussed the characteristics of service-oriented self-adaptation software. A context snapshot model to represent uncertainty is introduced in requirements with domain knowledge; and the context requirements to model user requirements and service requirements; and finally, propose means-c-end analysis to relate user and service requirement with context condition. We design and develop a support tool ConUSER to realize the uncertainty oriented requirement analysis.
