A Multi-scale GIS Database Model Based on Petri Net
Petri Net Scale Cartographic generalization
2015/8/17
In cartographic generalization, cartographic entities would change with scale. State and event are two basic elements to describe
these changes. However, current hierarchical multi-scale representati...
为解决动态故障树抽象而不利于交流的问题，利用Petri Net直观、易用且适用范围广的优点，提出基于Petri Net的飞机系统安全性指标分配方法。通过整理安全性指标及其相关的可靠性指标，选取失效率作为安全性指标，对比动态故障树及Petri Net建模方法，选取后者建立静态逻辑变迁和动态逻辑变迁的Petri Net指标分配模型。在此基础上，提出考虑严酷等级的系统安全性指标分配方法，经过算例分析，构...
