Development of reliability based water supply engineering

在发达国家，供水系统高度扩张和老化。应该进行适当的维护。另一方面，需要有效的管理和责任制。因此，科学合理的决策是必要的。本研究将可靠性工程发展的方法应用于供水系统管理。并联式和串联式系统分析应用于进水设施和过滤装置。介绍了故障树分析法，并将其应用于地震破坏后的应急供水和恢复。采用系统检测模型进行泄漏控制。研究了基于可靠性的管网设计方法。采用层次分析法对分布区域的比较可靠度进行了检验。最后，对可靠性改进项目的成本效益分析方法进行了研究。

In advance countries, the water supply system is highly expanded and aged. The proper maintenance should be done. In the other hand, effective management and accountability are required. Therefore, scientific and rational decision making is necessary.In this study the methodology developed by reliability engineering was applied to water supply system management. Parallel and series system analysis was applied for intake facilities and filtration plants. Fault tree analysis was introduced and used for emergency water supply and restoration after being damaged by an earthquake. System inspection model was use for leakage control. The methodology of pipe network design was investigated based on reliability. The analytical hierarchy process was applied to examine comparative reliability of distribution areas. Finally, the method of cost effectiveness analysis of reliability improve projects was investigated.
