Abstract
Wepropose timed SCR specifications, which are a generalizationof SCR specifications, intended to specify quantitative timingproperties of real-time systems. We extend the tabular notationof the SCR method to deal with sporadic and periodic timing constraints.We present a formal semantics for timed SCR specifications bytranslating them into timed transition systems. A shutdown systemin Korean nuclear power plants is used as a case study to illustratetimed SCR specifications.
