This paper presents applications of the log-linear ROCOF and the power law process to model the failure rate and estimate the economically optimal replacement time of the individual pipes in a water distribution system. The performance of the two failure rate models is examined using the...

In this this paper we combine economic factors that have strong trends and political factors that are stationary in a dynamic, empirical model of the evolution of public policy over a very long period in a stable democracy. The role of variation in the intensity of political competition is the...

Failure of a pipe or valve in a water distribution system causes service disruption and other inconveniences to the customers at or downstream of the failure location. To minimize the impact of such a pipe or valve failure, it is crucial to identify those pipes or valves whose failure will have...

Primary resource industries considering adaptation action in response to current or future climate changes need to consider the adaptive capacity of their constituent members if an industry-wide response is to occur. In particular, they need to know the extent to which the capacity to adapt...
