Trailer Types

From CTMS

This section allows configuration of different trailer types used in the system. Various parameters for each trailer are set here and affect how a trailer is chosen in processes such as Generate Transport Instructions and Trip Manipulation. Details such as maximum RPE constrain how much that type can hold. This section also allows configuration of the types of compartment present in a trailer type and how the different temperature types can be combined together.

Note that the "Drive Time Modifier" defaults to a value of "1.00" this can be used to factor speeds for vehicles such as vans and make them faster than articulated Lorries. For example, a vehicle with the "Drive Time Modifier" set to "0.5" would be twice as fast as one with a value of "1.0".

The trailer also has to have the compartments defined. This is shown on the right hand section of the screen, which enables you to allocate temperature compatibilities to the trailer types dependent on the site configuration and utilization. For example it may be possible to run with Chilled products on the headboard of the trailer and Ambient goods on the rear but not the other way round, this can be specified per trailer type. N.B. this section must be completed in order for trailers to be allocated to trips. Click New:

When setting up a new trailer type, you have to specify the length, volume and maximum RPE (Roll Pallet Equivalent) capabilities for that trailer which will be used when allocating the trailer to trips. The "Trailer Type" should give an abbreviated but concise description of the trailer as this will appear in "Trip Manipulation" and on reports, and the "Description" should be more detailed so that it is evident to transport departments exactly which trailer is required for the trip.

In most cases it will be the RPE value that governs the capacity of the trailer and once this has been set a trailer will not automatically allocate to a trip if its RPE capacity has been exceeded. There is also further validation with regard to trip creation and trailer validation, for example the smallest feasible trailer will be allocated to a trip in the first instance and if the largest possible trailer type is allocated and the capacity exceeded the trailer type will be maintained.

The trailer type allocated to the trip governs the "Trailer ID" which can be allocated if a carrier set to "Poplist" is being used and the "Refrigerated" and "Cost" boxes will restrict the usage of the trailers as it will use others first unless otherwise constrained (via restrictions set up by location). Constraints are generally defined by length which is why this is an important field to populate.

Temperature types represent certain types of goods that require storage at a certain temperature range. The temperature combination entries determine how the temperature types can be combined and in which compartments on a trailer they should be stored.
