Strategical and tactical asset management for the North Line in Portugal

The tool presented in this paper attempts to bridge the gap between the top management level of a company and maintenance planning, by providing a way to support strategic decisions with a clear evaluation of what would be required at the tactical level. It supports the infrastructure manager to answering questions like "If we have a reduction of the total budget of 10% are we still able to reach the requested quality level?". The tool will enable the infrastructure manager to estimate the consequences of strategic decisions, as it relies on detailing the tactical planning that would be necessary to execute. For this purpose, the tool was designed with a modular structure to ensure transferability to databases of other infrastructure operators.
