As a first step, the timeline model was defined as a function including the lifetime, the occurring maintenance events as well as their frequency and duration. All events were combined in one list. The choice of a common lifetime was problematic since each system has its own lifetime depending on technical and environmental conditions.\u00a0The lifetime of 50 years was set for all systems. For the Xpelair<\/a>, with a lifetime of 5 years, conversions needed to be done to meet the compromise.\u00a0Thus, the interventions were multiplied by the factor 10 in order to keep the calculation with a linear approximation simple.<\/p>\n

Subsequently, an iteration was implemented to include all possible scenarios between the systems, with a total of 15 combinations. After setting the start date and the lifetime, each event as well as its frequency and duration were implemented for the four individual systems. The following events were defined and visualized by a timeline for each subsystem:<\/p>\n
