    Abstract: A method for optimizing operation of a fleet of vehicles includes providing an optimization network including a plurality of nodes and a plurality of connections therebetween. The nodes define all potential destinations in the network for freight delivery or pickup. The connections define all potential sequences of nodes traversable over the network. The method determines a pre-optimization simulation matrix including a plurality of sets of energy expenditures for traversing respective ones of each of the connections. Each of the plurality of sets of energy expenditures accounts for permutations of a plurality of different vehicle powertrains present in a fleet of vehicles. The method performs an optimization using the pre-optimization simulation matrix, fleet information indicating locations and energy states of a plurality of vehicles in the vehicle fleet, mission information indicating a pickup or delivery destination for a plurality of items of freight, and a fleet optimization objective.

    Abstract: Systems and methods for conditioning an aftertreatment system. For example, a computer-implemented method for conditioning an aftertreatment system of a hybrid system including an electric motor and a combustion engine includes: determining whether the aftertreatment system is in a first temperature zone below a first temperature threshold; determining whether a power demand corresponding to the operation of the hybrid system is in a first power demand zone below a power threshold; and if the aftertreatment system is determined to be in the first temperature zone and the power demand of the hybrid system is determined to be in the first power demand zone, setting the hybrid system to compressor mode to heat the aftertreatment system.
