Resource Demanding Service Effect Specification

A resource demanding service effect specification (RDSEFF) [33] is a special type of SEFF designed for performance and reliability predictions. Besides dependencies between provided and required services of a component, it additionally includes notions of resource usage, data flow, and parametric dependencies for more accurate predictions. Its control flow is hierarchically structured and can be enhanced with transition probabilities on branches and numbers of iterations on loops. In the following, the meta model of the RDSEFF will be illustrated, and its design rationale will be explained. For understanding and clarity, the illustration of the meta model and the concept descriptions are spread over several paragraphs.
