ElMaraghy, Comprehensive Complexity-Based Failure Modeling for Maintainability and Serviceability, Proceedings of the 1st CIRP Industrial Product-Service Systems (IPS2) Conference, Cranfield University, 1-2 April 2009, pp89978-0-9557436-5-8http://hdl.handle.net/1826/3626Organised by: Cranfield UniversityFailures are the primary triggers for repair and maintenance actions. A clear definition of failure events is important in order to improve maintainability and serviceability. A comprehensive complexity-based mathematical definition of failure is introduced. The applicability of the developed failure model to different complexity definitions is discussed. A new metric is introduced to capture the change in complexity associated with function degradation. A case study is presented to illustrate the application of the new failure definition and metric. The developed approach for failure modeling can be used for maintenance planning.enCopyright: Cranfield University, 2009FailureMaintenanceServiceabilityComplexityManufacturing SystemsConference paper
