摘要
针对由周期行为和模式转换机制组成的实时系统提出的SPARDL需求建模语言,详细阐明了其对应的SPARDL模型的Event-B解释。通过Event-B来解释SPARDL的语义,同时提出一种基于SPARDL模型特征的精化框架用于Event-B模型的开发。最后,通过案例研究的分析展示用Event-B对SPARDL模型建模和验证的方法的有效性。
A requirement modeling language called SPARDL was proposed for modeling and analyzing such periodic control systems consisting of periodic behaviors together with the mode transition mechanism.The Event-B interpretation was specified for the SPARDL model.The semantics of SPARDL were presented by Event-B and a refinement framework was introduced to develop the Event-B models based on the features of the SPARDL model.Finally,a case study was analyzed to show the effectiveness of our proposed approach to modeling and validation of the SPARDL model by Event-B.
