10:00 – 10:10 welcome, introduction
10:10 – 11:10 theory: methodologies of economic evaluation
11:10 – 11:25 Q and A / break
11:25 – 12:25 example: evaluation of an innovative track component
12:25 – 12:40 Q and A / break
12:40 – 13:10 costs of non-availability – integration and calculation
13:10 – 13:25 discussion
13:25 – 13:30 preview on topics of coming up seminars
After already two seminars on the basics of life cycle management this seminar is the first of a sequence dealing in detail with different aspect of life cycle management for railway infrastructure.
In principle asset management needs to argue decisions on investment, maintenance, and economic service life – which are heavily interlinked. Thus, the technical situation needs to be pictured in costs for evaluating the economic efficiency of different options. This seminar presents methodologies of economic evaluation and their specific expressions in the field of railway infrastructure discussing theory and presenting real examples. The coming up seminars will deal with data, data analyses, technologies, track behaviour, and prognoses.
About weTHINK. Railway LCM
Goal is to build a knowledge exchange community for best practices on technical sustainability and economic efficiency for track superstructure.
Increasing traffic pushes on track deterioration but also limits time for track work more and more. To overcome this problem further development of track must target more sustainable track components and track maintenance to reduce the demand of track possession without reducing track quality. This requires understanding of track deterioration, gained by time sequences of track data allowing forecasting of track behaviour and thus preventive maintenance.
R&D within track needs to present sustainable solutions which show a high economic efficiency. As track shows costs only, track strategies can be economically evaluated by comparing different options. Standard evaluations can be used as calculating the dynamic annual average costs. Dynamic methods are required due to the long service lives of track, annual average costs are used to enable comparing strategies with different service lives. Furthermore costs of non- or reduced availability due to either track work or due to speed restrictions caused by poor quality need to be taken into account for a proper evaluation of track component and/or track maintenance strategies. These methodologies will be presented theoretically and on real examples.
