| 摘 要： | 在管网维修时,为了实现合理有效地利用有限的资金目标,提出了基于半Markov过程的维修资金分配优化模型。模型的目标函数是求系统可靠性即整个系统各管段加权长期可靠性和的最大值。在该维护程序中使用了水力可靠性来确定管段的权重。并以实例说明如何利用这个模型进行实际的运算。

| Abstract: | In maintenance of a water distribution network,the model based on semi-markov processes is proposed in order to achieve rational and efficient use of limited funds.The objective function of the model is to gain the system reliability,i.e.the maximum of the total weighted long-run reliability of the whole system.The concept of hydraulic reliability is employed to determine the weight of pipes in the maintenance programme,and an example is given to illustrate how this model is used for the actual computation. |
