RMC (Ready-mixed concrete) vehicle scheduling problem is a complex combinatorial optimization problem with intersection of several research areas, such as logistics, just-in-time production and supply chains etc. We integrates RMC production scheduling and vehicle dispatch problems in the same framework by network flow techniques and establishes a mixed integer programming model for ready-mixed...

The paper studies a series-parallel hybrid powertrain configuration for the medium-duty plug-in hybrid trucks and Volt-like passenger cars. The series-parallel hybrid combines the features of the parallel hybrid and the series hybrid. Series-parallel hybrid powertrains with preand post-transmission configuration for the plug-in hybrid medium-duty trucks were modelled and compared with a convent...

The main contributions of this paper are the development of a forward-looking hybrid vehicle simulation tool, and its application to the design of a power management control algorithm. The hybrid electric vehicle simulation tool (HE-VESIM) was developed at the Automotive Research Center of the University of Michigan to study the potential fuel economy and emission benefits of the parallel hybri...

In order to ensure superiority of fuel and improve start and stop performance of hybrid electric vehicle, battery is used in the system. Limited by vehicle’s size, traditional hybrid electric vehicles can only carry a limited number of batteries, resulting in a relatively short running distance in one battery charge cycle. To improve energy using efficiency and increase vehicle safety, composit...

A new hybrid-drive system taking flywheel energy storage system instead of chemical battery as assistant power source for hybrid electric vehicle is put forward. According to the particular energy characteristics of flywheel system, an energy management strategy based on fuzzy logic control is also developed with overall consideration on the optimization of both ICE (Internal Combustion Engine)...

this paper addresses the vehicle routing problem with delivery time cost. this problem aims to find a set of routes of minimal total costs including the travelling cost and delivery time cost, starting and ending at the depot, in such a way that each customer is visited by one vehicle given the capacity of the vehicle to satisfy a specific demand. in this research, a hybrid metaheuristic approa...

Researchers have proposed that fleets of plug-in hybrid vehicles could be used to perform ancillary services for the electric grid. Inmany of these studies, the vehicles are able to accrue revenue for performing these grid stabilization services, which would offset the increased purchase cost of plug-in hybrid vehicles. To date, all such studies have assumed a vehicle command architecture that ...
