Journal Article
Papadopoulos, Y., & Walker, M. (2009). Qualitative temporal analysis: Towards a full implementation of the Fault Tree Handbook. Control engineering practice, 17(10), 1115-1125. https://doi.org/10.1016/j.conengprac.2008.10.003

The Fault tree handbook has become the de facto standard for fault tree analysis (FTA), defining the notation and mathematical foundation of this widely used safety analysis technique. The Handbook recognises that classical combinatorial fault trees... Read More about Qualitative temporal analysis: Towards a full implementation of the Fault Tree Handbook.

Semi-automatic FMEA supporting complex systems with combinations and sequences of failures (2009)
Journal Article

SAE International Journal of Passenger Cars - Mechanical Systems, 2(1), 791-802. https://doi.org/10.4271/2009-01-0738

Failure Modes and Effects Analysis (FMEA) is a well established safety analysis technique used for the assessment of safety critical engineering systems in the automotive industry. Although FMEA has been shown to be useful, the analysis is typically... Read More about Semi-automatic FMEA supporting complex systems with combinations and sequences of failures.

Multi-objective optimization of dependability attributes using an asynchronous heterogeneous hierarchical parallel genetic algorithm (2008)
Journal Article
Wenhua, Z., Papadopoulos, Y., & Parker, D. (2008). Multi-objective optimization of dependability attributes using an asynchronous heterogeneous hierarchical parallel genetic algorithm. IFAC Proceedings Volumes/ International Federation of Automatic Control, 41(3), 199-204. https://doi.org/10.3182/20081205-2-cl-4009.00036

The optimal satisfaction of dependability attributes and cost, in the design of engineering systems, is a hard multi-objective optimization problem which requires automated algorithms that can effectively search large design spaces. In this paper, a... Read More about Multi-objective optimization of dependability attributes using an asynchronous heterogeneous hierarchical parallel genetic algorithm.

Synthesis and analysis of temporal fault trees with PANDORA: the time of Priority AND gates (2007)
Journal Article
Walker, M., & Papadopoulos, Y. (2008). Synthesis and analysis of temporal fault trees with PANDORA: the time of Priority AND gates. Nonlinear Analysis: Hybrid Systems, 2(2), 368-382. https://doi.org/10.1016/j.nahs.2006.05.003

Classical Fault Tree Analysis (FTA) can determine the effects of combinations of failure events on a system but cannot capture the significance of the temporal order of events, which may be critical. In this paper, we propose an extension based on fo... Read More about Synthesis and analysis of temporal fault trees with PANDORA: the time of Priority AND gates.
