Route guidance: static or dynamic routes?

The strategic question for route planning

Different route concepts can and should be used for material flow depending on the type and purpose of the tugger train system. The main difference is between dynamic and static route guidance.


Static routes

Static routes follow a defined timetable that specifies exact times and routes.

Advantages:

  • Predictable replacement times
  • Very reliable process
  • Errors are easy to trace
  • Can be used without digital control, e.g. with a paper kanban system

Disadvantages:

  • Only cost-effective with consistent levels of use
  • Poorer utilisation of the tugger train system in comparison to dynamic routes when faced with fluctuations in production quantities
  • No prioritisation of stopping points in the supply process
  • No flexible route guidance and loading and unloading can only be carried out on one side
  • Significantly more trains are required because one train carries out less work
With the static route, no route deviations are possible - it is firmly defined.

Dynamic routes

The synchronisation of production and logistics processes with tugger train systems requires that production areas are supplied with small lot sizes as needed. This is the only way to reduce the quantity of stock in production.

Ideally, stock is always supplied in line with usage and demand. This is possible with dynamic route guidance, as it has neither a specific timetable nor a defined course. The route is planned according to time, route distances and the part of the production line with the most urgent need.
