Abstract

A new approach to managing complex infrastructure systems has been developed. The system is represented hierarchically incorporating both high level business processes and operational processes. Performance of sub-systems 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 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 flood defence system demonstrates how the approach provides a useful overview of system performance and can help support decisions.
