| 摘 要： | 在分析复杂任务特点的基础上,针对一般模型无法反映资源约束对任务过程的影响以及任务过程间的相关性问题,提出了E-GERTS模型及其计算机仿真算法。该模型通过添加决策型节点和决策函数,可根据当前资源和时间信息,对任务过程进行动态决策,确定后续任务节点的分支概率,从而有效地解决了这些问题。同时还给出复杂任务成功性评估的E-GERTS模型建立方法,最后给出了一个示例。

| Abstract: | On the basis of analysis of the characteristics of complex mission, this paper presents an extended GERTS model. An extended node named decision-making node with decision-making is defined in this model. It can describe the complex mission process whose branch probabilities are changeable dynamically and its computer simulation algorithm is given. At the same time, this paper gives the basic steps on construction of E-GERTS model which is used in evaluation of availability of complex mission. Finally, an example is given. |
