MODIFIED SAPPHIRE MODEL AS A FRAMEWORK FOR PRODUCT LIFECYCLE MANAGEMENT

Testing and in-service information remains difficult to manage under current Product Lifecycle Management (PLM) frameworks. While several researchers have proposed solutions, the temporal and behavioural aspects of the lifecycle have not always been explicitly considered. In this paper, it is demonstrated how the SAPPhIRE model of causality can be applied to PLM. An extended model is proposed, and through the use of design, manufacturing, and in-service scenarios, its feasibility as a future PLM model is explored. Future work includes validating the model through concrete case studies.
