Maintenance scheduling in critical infrastructure networks

Coauthors: Natashia Boland, Thomas Kalinowski, Zheng Lanbo

 

Abstract:
Many infrastructure systems critical to modern life take the form of a
flow in a network over time. For example, utilities such as water,
sewerage and electricity all flow over networks. Products are
manufactured and transported via supply chain networks. Such networks
need regular, planned maintenance in order to continue to function. A
maintenance job causes arc outages for its duration, potentially
reducing the capacity of the network for that period. The coordinated
timing of maintenance jobs can have a major impact on the network
capacity lost to maintenance. This issue drives an annual maintenance
scheduling process at the Hunter Valley Coal Chain, which supplies the
world's largest coal export operation at the port of Newcastle,
Australia, and has motivated this work. Here we describe the
background to the problem, how we model it, and our solution approach.
The results on instances derived from real-world data will be
presented
