3.2.2.1. CTV. In order to represent the operational environment,
the CTV operations are modelled in a comprehensive way
representing a more sophisticated analysis approach than
previous work in this area. In this context, transit time
calculations are performed in each repair day, and ‘Travel time’,
‘Non-productive time’, and ‘Productive time’ values for each CTV in
the O&M fleet are calculated considering the fact that each time
step has different climate conditions. The steps below are followed
in the transit time modelling, and repeated for each CTV;
