Modelling and application of condition-based maintenance for a two-component system with stochastic and economic dependencies (2018)
Journal Article
Do, P., Assaf, R., Scarf, P., & Iung, B. (2019). Modelling and application of condition-based maintenance for a two-component system with stochastic and economic dependencies. Reliability Engineering and System Safety, 182, 86-97. https://doi.org/10.1016/j.ress.2018.10.007

This paper develops a model of a condition-based maintenance policy for a two-component
system with both stochastic and economic dependencies. The stochastic dependency is such
that the degradation rate of each component depends not only on its own... Read More about Modelling and application of condition-based maintenance for a two-component system with stochastic and economic dependencies.

Wear rate-state interactions within a multi-component system : a study of a gearbox accelerated life testing platform (2018)
Journal Article
Assaf, R., Do, P., Nefti-Meziani, S., & Scarf, P. (2018). Wear rate-state interactions within a multi-component system : a study of a gearbox accelerated life testing platform. Proceedings of the Institution of Mechanical Engineers, Part O: Journal of Risk and Reliability, 232(4), 425-434. https://doi.org/10.1177/1748006X18764061

The degradation process of complex multi-component systems is highly stochastic in nature. A major side effect of this
complexity is that components of such systems may have unexpected reduced life and faults and failures that decrease
the reliabil... Read More about Wear rate-state interactions within a multi-component system : a study of a gearbox accelerated life testing platform.

Joint maintenance-inventory optimisation of parallel production systems (2018)
Journal Article
Zahedi-Hosseini, F., Scarf, P., & Syntetos, A. (2018). Joint maintenance-inventory optimisation of parallel production systems. Journal of Manufacturing Systems, 48(Part A), 73-86. https://doi.org/10.1016/j.jmsy.2018.06.002

We model a joint inspection and spare parts inventory policy for maintaining machines in a parallel system, where simultaneous downtime seriously impacts upon production performance and has a significant financial consequence. This dependency between... Read More about Joint maintenance-inventory optimisation of parallel production systems.

Optimisation of inspection policy for multi-line production systems (2018)
Journal Article
Zahedi-Hosseini, F., Syntetos, A., & Scarf, P. (2018). Optimisation of inspection policy for multi-line production systems. European Journal of Industrial Engineering, 12(2), 233. https://doi.org/10.1504/EJIE.2018.090616

This paper develops a simulation model to determine the cost-optimum inspection policy for a multi-line production system taking account of simultaneous downtime. The machines in the multi-line system are subject to a two stage failure process that i... Read More about Optimisation of inspection policy for multi-line production systems.
