Appian Daily Planner and Resource Calendar use the terms Assets and Trucks to differentiate between your fleet’s actual vehicles (Assets), and the set of rules (Trucks) the routing algorithm uses to build routes for those vehicles. 

• An Asset is a vehicle identifier. Each Asset has a Name, which should be unique within the branch, and a Type, which is a standard, shared description of the type of truck (e.g. Box, Lift, Semi.) Name and Type are created by users in whatever format works best to identify and sort a fleet’s vehicles in Daily Planner. 
• A Truck is a collection of settings that govern how a route is built. It includes dozens of fields the algorithm might need to know in order to generate an efficient route—everything from the type of vehicle to its hours of availability, costs, and any special equipment it might have available. Trucks are grouped together in Truck Profiles.
