In the Transport simulation submodule, various parameters can be set in the Simulation parameters view. One parameter is the granularity of the resource requirement. The resource demand can be calculated coarsely or finely. The calculations can be found here.
|Resource requirements rough||Orders can be transported at any time during the day, taking into account the break times. (The calculation is usually faster than the fine calculation).|
|Resource requirements fine||The simulation tolerance describes a time deviation in hours from the earliest and latest staging times for the fulfillment of transport orders.|
Furthermore, the calculation logic for the transports can be set. In this way, it can be defined individually in each project whether the transports should fulfill the shortest route or the shortest transport time criterion in the calculation.
Under the point Pathfinding strategy for means of transport the selection between these two criteria is possible.
If the shortest transport path is set, the means of transport travel the shortest distance in metres between the stopping point of the source and the stopping point of the sinks. When calculating the shortest path, the restrictions defined in the Create transport network submodule are always taken into account.
When selecting the criterion shortest transport time, the shortest travel time between the stopping point of the source and the stopping point of the sink is decisive.
The calculation of the duration is as follows:
∑ Distance length per section (m) / permitted speed (m/s)
Here, too, the defined restrictions are taken into account for the lines and the speeds.
The permitted speed must always take into account that the following applies:
- Speed restriction > Speed in resource management → Speed from resource management is used
- Speed restriction < speed in resource management → Speed restriction is used
By default, the shortest transport time criterion is active.
The setting is taken into account as soon as it is saved. For example, the transports must be recalculated.
Under the item Allow transfers during breaks, transfers are allowed during break times if a tug is needed to carry out orders elsewhere. Transfer journeys are only performed for direct transports and are always empty journeys.
Use weight restrictions for transports allows to simulate transports with weight restrictions. The option can be enabled only if the dynamic calculation of trailer capacity is enabled.
