Entities such as orders, locations and vehicles within a scenario must have a unique identifier (Id) that is used to refer to them.
Identifiers must contain at least one character and must not contain the semicolon (;) character. They are not case or “white space” sensitive.
For example, “DEPOT2”, “depot2” and “Depot 2 ” will all be treated as identifying the same entity by the optimiser because they only differ in case or the amount of white space they have.
Even though they may be composed of digits, identifiers are not numeric. For example, the optimiser will treat “1” and “001” as being distinct identifiers.
(Users of the DTO-Excel format should be aware that there are Excel-specific restrictions on the specification of identifiers; see Section 3.1 for details.)
All references to an entity are made using its identifier.
