Various technical systems are composed of multiple components. Whether the system fails once one of the components fails (series system), all components fail (parallel system) or a specific number of components fail (n-out-of-k system), the main aim in reliability analysis is to better understand the lifetime behaviour of the individual components as well as the whole system.

In applications it is the goal of cost reduction which drives this ambition as the estimation of average lifetimes and the prediction of future failures governs how maintenance schedules, warranty bonds or bulk replacement strategies are deployed.

Tim's presentation will introduce a highly sophisticated model for technical systems consisting of components with different lifetime behaviours which share a common workload. So called load-sharing systems operate under the assumption that failure of one component can alter the lifetime expectation of other components.

This dependence structure will be represented using sequential order statistics. The distributional results will yield reliable estimators to better predict future component and system failures.
