A Heavy‐Duty Vehicle Routing Problem With Temperature Constraints

Networks
ABSTRACT This article studies a vehicle routing problem involving a fleet of heavy‐duty vehicles and pickup‐and‐delivery requests for crude items that are both heavy and high‐temperature. The objective is to route the fleet in such a way that maximizes resource efficiency and operational efficiency while simultaneously avoiding ...

Factors Affecting Heavy-Duty Diesel Vehicle Emissions [PDF]

Journal of the Air & Waste Management Association, 2002
Societal and governmental pressures to reduce diesel exhaust emissions are reflected in the existing and projected future heavy-duty certification standards of these emissions. Various factors affect the amount of emissions produced by a heterogeneous charge diesel engine in any given situation, but these are poorly quantified in the existing ...
