Petri Nets and Pseudo-Bond Graphs for a Nuclear Reactor Primary Coolant System (2019)
Conference Proceeding

In this paper we demonstrate the application of timed Petri Net methodology to the frequency of initiating faults in the coolant circulation system of a fictional nuclear reactor design. A second model is presented where the Petri Net is coupled with... Read More about Petri Nets and Pseudo-Bond Graphs for a Nuclear Reactor Primary Coolant System.

A petri net methodology for modelling the maintenance of railway route sections (2019)
Conference Proceeding

Railway utilization is increasing. In 2017-18 there were over 1.7 billion passenger journeys made on the UK railway network, more than double the number made in 1995. Therefore getting maximum performance from the existing network by streamlining mai... Read More about A petri net methodology for modelling the maintenance of railway route sections.

Efficient risk based optimization of large system models using a reduced petri net methodology (2019)
Conference Proceeding

The methodology presented in this paper is a two-stage optimization approach that can be applied to large system level models, in this case using a Stochastic Petri Net (SPN) framework, to produce an equivalent model response at a reduced computation...

Development of an extended RAMS framework for railway networks (2019)
Conference Proceeding

Railway asset managers have finite resources which requires them to make strategic decisions on where, when and how the available budget will be spent on the railway, while ensuring safety limits are maintained and a high level of performance is deli...

Optimising Rail Replacement Bus Services During Infrastructure Possessions (2019)
Journal Article

Providing rail-replacement bus services is a common strategy applied to handle track blockage situations in railway networks. Previously, a great deal of research has focused on modelling this strategy, particularly in the case of unplanned disruptio...

An efficient algorithm for computing exact system and survival signatures of K-terminal network reliability (2019)
Journal Article

An efficient algorithm is presented for computing exact system and survival signatures of K-terminal reliability in undirected networks with unreliable edges. K-terminal reliability is defined as the probability that a subset K of the network nodes c...
