| 摘 要： | 介绍了闭合排队网络的扩展求和算法(Extended Summation Algorithm， ESUM）原理和迭代计算过程，就一个露天矿装运系统建立了闭合排队网络模型，并分别应用ESUM算法和随机模拟方法对模型进行了计算分析.结果证明，在分析露天矿装运系统时，采用ESUM算法能够以较高的精度有效地对系统的非负指数排队网络模型进行求解.ESUM方法是比计算机模拟法更简便的露天矿装运系统分析方法.

| Abstract: | The application of extended summation algorithm(ESUM) in the analysis of the shovel-truck system in open cast mines was introduced.The closed queueing network model of a practical shovel-truck system was constructed and analyzed by both ESUM and computer simulation.By means of comparison of the two results obtained by the two above-mentioned methods,it is proved that ESUM can be used effectively to analyze non-exponential queueing network models of shovel-truck systems with good accuracy.ESUM is simpler tha... |
