Downtimes at depots and stop points

At stop points you can specify for each vehicle combination, whether the stop point should be used as a depot by the vehicle combination. A capacity and a minimum downtime time can be specified for each vehicle combination. The capacity is restricted to the number of vehicle combinations, which are allowed to stop at the same time at the stop point (as a depot), as long as the capacity > 0; for capacity = 0 the depot capacity is unlimited. Depots are therefore stop points with downtime function. The downtime in the depot is evaluated with a cost rate that is different (usually lower) from the cost rate for the downtime at a stop point, though both downtimes belong to the block item type layover. A difference is made between the same stop point in its role as a depot and as a stop point.

Table 223: Depot attributes of stop points
Attribute	Description
Is depot	Specifies that the stop point is a depot. A stop point is a depot if either at least one vehicle combination is permissible or the entry Default values is permissible.
Is depot for standard vehicle combination	Specifies whether the entry Default values (No combination = Not vehicle combination specific) is permissible.
Minimum depot layover time	Minimum downtime per vehicle combination in the depot.
Minimum depot layover time for standard vehicle combination	Minimum downtime in the depot for default vehicle combination (entry Default values).
Depot capacity	Capacity per permissible vehicle combination. This is the number of vehicles per combination, which is allowed to simultaneously be at the depot. For the value = 0 the capacity is not limited for the respective vehicle combination.
Depot capacity for standard vehicle combination	Capacity for the vehicle combination no combination (entry Default values). For the value = 0 the capacity is not limited for the standard vehicle combination.
Activity is allowed for vehicle combination set	Vehicle combination set for which the stop point allows a recurring activity
Activity capacity	Stop point capacity per activity. The maximum number of simultaneous executions of an activity, indicated by instances of the vehicle combination is indicated. The capacity of 0 for a permitted vehicle combination equals unrestricted capacity.

Cost rate layover hour	Cost rate for downtimes at stop points, not at depots
Cost rate layover hour units	Sum of cost rates of the vehicle units for downtimes at stop points
Cost rate layover hour total	Total cost rate for downtimes at stop points (= cost rate per layover hour + cost rate per layover hour from vehicle units)
Cost rate depot hour	Cost rate for stay at depots
Cost rate depot hour units	Sum of cost rates of the vehicle units for downtimes at depots
Cost rate depot hour total	Total cost rate for downtimes at depots (= cost rate per depot hour + cost rate per depot hour from vehicle units)
