描述了一种用于管理复杂基础设施系统的性能的软件支持的方法。基础设施系统以分层方式表示，因此可以通过相同的方法支持高层业务决策和更详细的运营决策。每个子系统的性能由一组保存在数据库中的性能指标来捕获。性能的证据是从所有可用的来源收集的，从监测测量和检查记录、设计计算和模型研究到专家判断、类似案例和过去故障的说明。这些绩效指标通过反映组织目标和监管标准的价值功能进行预测，并合并以生成系统和每个子系统的绩效指标。可用证据中的不确定性使用区间概率理论通过证据层次结构来表示和传播，从而对决策中不确定性的来源和影响提供评论。一个水电水库系统的案例研究表明，该方法可以用来提供一个连贯的概述系统的性能和支持资产管理决策。
A software-supported methodology for managing the performance of complex infrastructure systems is described. The infrastructure system is represented hierarchically, so that high level business decisions and more detailed operational decisions can be supported by the same methodology. Performance of each sub-system is captured by a set of Performance Indicators held in a database. Evidence of performance is assembled from all available sources, ranging from monitoring measurements and inspection records, design calculations and model studies to expert judgements, analogous cases and accounts of past failures. These Performance Indicators are projected through value functions reflecting organisational objectives and regulatory standards and are merged to generate a Figure of Merit for the system and each sub-system. Uncertainty in the available evidence is represented and propagated through the evidence hierarchy using Interval Probability Theory, providing a commentary on sources and implications of uncertainty in the decision. A case study of a hydro-electric reservoir system demonstrates how the approach can be used to provide a coherent overview of system performance and support asset management decision-making.
