摘　　要：针对传统方法在评价列控系统安全通信协议性能时存在只能定性不能定量和对评价人员掌握评价尺度有差异考虑不足的问题,基于利用有色Petri网模型对列控系统安全通信协议性能的仿真结果,运用决策论中的概念格理论对有关安全通信协议性能(包括建立安全链接需要的时间和传输信息需要的时间)的仿真数据进行分析,研究制定安全通信协议的性能评价规则。运用Dempster-Shafer理论,分析评价人员应用给出的安全通信协议性能评价规则对安全通信协议性能进行评价所得评价结果的不确定性,以验证所提出安全通信协议性能评价规则的可行性。结果表明,使用所制定的安全通信协议性能评价规则克服了传统方法的不足,而且以概率的形式定量表示安全通信协议的性能,可使评价结果更全面也更具有说服力。By using traditional methods,it is only possible to qualitatively rather than quantitatively evaluate the performance of safety communication protocol in traincontrol system.Furthermore,there are insufficient considerations onthe differences in the evaluation scales mastered by the evaluators.To solve these problems,a method of formulating rules for the performance evaluation of safety communication protocol is proposed.In the method,the simulation resultsof the performances of the safety communication protocol in train control systemis first obtained by using colored Petri net models.Then the concept lattice theory in decision theory is adopted to analyze the simulation results.The performances of the protocol include the time needed to establish safety connection and the time needed to transmit information.To prove the feasibility of the proposed performance evaluation rules for safety communication protocol,severalevaluators are asked to evaluate the performance of the protocol according to the proposed rules,and the uncertainties of the evaluation results are analyzed by using the Dempster-Shafer theory.Results show that the shortcomings of the traditional methods are overcome by using the proposed performance evaluation rulesfor safety communication protocol.Moreover,the performances of the protocol are qualitatively presented in the form of probability,which makes the evaluationresults much more comprehensive and convincing.
