Function documentationScheduling

 

In scheduling, the system calculates start and end dates/times for all valid trips. Here it takes into account calendars and times for the following activities:

  • Transshipment

  • Departure/shipping

  • Transportation

  • Arrival/receipt

Scheduling is part of route determination in the routing guide (see Route Determination). When you simulate route determination (see Simulation of Route Determination), the system displays detailed results of scheduling. The following sections are particularly relevant to this case.

Integration

See Route Determination.

Prerequisites

For scheduling, the following prerequisites must be met:

  • You have defined the following in the master data for route determination:

    • Locations with geocoordinates

    • Transshipment locations with minimum goods wait time and arrival calendar

    • Optionally, transportation lanes with transportation calendars, transportation durations, and distances

    • Routes with departure calendars (see Route)

  • You have defined the average speed and the “actual distance versus aerial distance” factor for all relevant means of transport in Customizing for SCM Basis under Start of the navigation path Master Data Next navigation step Transportation Lane Next navigation step Maintain Means of Transport End of the navigation path.

  • See also the prerequisites under Route Determination.

Features

Scheduling is based on the following activities:

  • Transshipment

  • Departure/shipping

  • Transportation

  • Arrival/receipt

The system takes into account these activities in this order for each leg of trip, whereby transshipment is not relevant to the first leg of the trip.

The routing guide chooses the relevant locations of the leg before scheduling, and defines a fixed order for them in accordance with the sequence strategy that you have defined for the leg. Here the following applies:

  • A location is part of a leg if either itself or one of its zones is a stop along the leg.

  • A location of a leg is relevant if it does not lie before the start location or after the destination location of the request, and is either a transshipment location or part of a leg for which you cannot skip stops.

    Note Note

    In scheduling, the routing guide only takes into account transportation lanes between sequential locations in the sequence that the routing guide defined before scheduling.

    End of the note.

Scheduling of activities is based on the following data:

  • Transshipment

    Transshipment duration: minimum duration of the goods wait time at the transshipment location

  • Departure/shipping

    Departure calendar: departure calendar of the leg, if available, or shipping calendar of the start or transshipment location

  • Transportation (for each stage of a trip)

    • Transportation calendar: you define the transportation calendar for a stage by defining a transportation lane.

    • Transportation duration: if you have not defined a transportation duration for the transportation lane, the system checks if a value exists for the transportation distance for the transportation lane. It then multiplies this with the average speed of the means of transport used for the leg. If you have not defined any of these values for the transportation lane or have not defined a transportation lane at all, the system estimates the transportation distance on the basis of the geocoordinates of the two locations. It then multiplies this value with the average speed of the means of transport used for the leg.

  • Arrival/receipt

    Arrival calendar: Receiving calendar of the transshipment or destination location
