This paper presents a continuous approximation model for the Vehicle Routing Problem for Emissions Minimization (EVRP) and demonstrates the model’s applicability and usefulness with numerical studies based on implementations of the Solomon test instances. The EVRP is a variant of the Time Dependent Vehicle Routing Problem (TDVRP) in which minimizing emissions is an additional objective of the m...

Background Accurate identification of serious injury is critical to the tasking of scarce resources like air ambulances and for the effective triage of injured patients to trauma centres. This service dispatches a doctor-paramedic team to major trauma patients. Dispatch is based on mechanism of injury (MOI); dispatching control room paramedic interrogation of caller (INT) or request after asses...

The new Internet Protocol version 6 (IPv6) [1] has many simplifications and new features compared to the older Internet Protocol version 4 (IPv4) [2]. The new header is very simple. A fixed format is assigned to all headers. Some new fields were added to the header. Flow ID indicates that the packet belongs to a certain flow. A flow is identified by the source address, destination address, and ...
