Vehicles are moving resources that transport goods between locations, for example, trucks, rail-cars, planes, and ships. Each vehicle resource represents a unit load, for example, one trailer of a certain capacity, one container of a certain capacity, or one rail car of a certain capacity. Eight dimensions and unit of measurements can be used to define vehicle capacity, for example, mass, volume–that is, the capacity of a trailer can be specified as 40,000 lb, or 2200 cu ft/s, or 24 pallets. Planning can only take the vehicle capacity into account if these dimensions and unit of measurement correspond to the dimensions and unit of measurements that are defined in a freight unit building rule.
Vehicle group and vehicle types specify attributes such as the physical properties of a certain kind of vehicle.
All vehicles are assigned to a means of transport (transportation method). Means of transport are groups of vehicle resources. The transportation mode is assigned to the means of transport. The transportation mode specifies how the goods are transported, for example, as a sea shipment.
There are two types of vehicle resources: passive and active. Active vehicle resources can travel by themselves. Passive vehicle resources cannot travel by themselves. A truck that has a motor and can travel by itself is an active resource. An empty trailer with no tractor is a passive resource.
The means of transport and factory calendar should be defined before creating a vehicle resource. When creating a vehicle resource, it is recommended that the following information is input:
- A resource name
- A calendar and time zone
- A capacity
The following fields combined together define capacity and volume and are mandatory for creating a resource:
- Factory Calendar
- Continuous Dimension
- Capacity
- Unit of Measure
MTr combinations can be used to model truck and trailer combinations. Multiresources can be used to model an external fleet in one step.
Compartments
Compartments can be used to indicate a division of the vehicle resource (truck) and also the trailer into smaller units. Capacity constraints can be specified for compartments. Furthermore, they offer the following benefits:
- Flexible and fixed compartments
- Incompatibilities can be used to restrict certain freight units from being transported in certain compartments, for example, because of temperature restrictions
The use of compartments allows you to assign dangerous goods to certain areas of the truck. In addition, the use of compartments improves transportation planning for oil and gas, chemical, retail, and consumer products.
Means of Transport Combinations
A means of transport combination is an instance of a particular means of transport, or a group of identical instances of means of transport that can provide transportation services. You use this business object to map the capacity and availability of vehicles that you want to use for transportation.
MTr combinations have the following attributes:
- They can be used to model a truck and trailer combination.
- You specify the number of the objects of each MTr within the combination, for example, one truck and two trailers.
- You specify capacities (several UoM): Maximum capacities of the combination.
- Additional (freely definable) attributes can be used for compatibilities and incompatibilities; based on a customizable attribute definition (code + text).
- Coupling/un-coupling durations are defined per passive MTr.
