In this paper we present a local search heuristic method for an integrated airline scheduling, fleeting and pricing model. The integrated model simultaneously optimizes the decisions of schedule design, fleet assignment, seat allocation, pricing and considers passengers’ spill and recapture. The resulting problem is a mixed integer non-convex problem due to the explicit representation of a dema...

A microscale emission factor model (MicroFacPM) for predicting real-time site-specific motor vehicle particulate matter emissions was presented in the companion paper titled "Development of a Microscale Emission Factor Model for Particulate Matter (MicroFacPM) for Predicting Real-Time Motor Vehicle Emissions". The emission rates discussed are in mass per unit distance with the model providing e...

OBJECTIVES In the year 2000, as part of the process for setting New Zealand road safety targets, a projection was made for a reduction in social cost of 15.5 percent associated with improvements in crashworthiness, which is a measure of the occupant protection of the light passenger vehicle fleet. Since that document was produced, new estimates of crashworthiness have become available, allowing...

The paper refers to the importance of maintenance management to increase the vehicle fleet energy efficiency. The fleet maintenance management influences as the vehicle maintenance process itself as well as the primary transport process but also their environment. In order to increase fleet energy efficiency by means of a more efficient maintenance management, it is indispensable to observe mai...

Abstract: In machine job shops with automated guided vehicles (AGVs) as mean of transportation of job parts, it’s usually hard to determine the optimal fleet size of AGVs for achieving a desired performance. In this paper a heuristic AGV dispatching algorithm is constructed based on the concept of ideal pipeline and Petri Net theory to balance the job part scheduling and AGV dispatching that mi...

Measurements of aerosol particle number size distributions (18–700 nm), mass concentrations (PM2.5 and PM10) and NOx were performed in the Plabutsch tunnel, Austria, and in the Kingsway tunnel, United Kingdom. These two tunnels show different characteristics regarding the roadway gradient, the composition of the vehicle fleet and the traffic frequency. The submicron particle size distributions ...

BACKGROUND There are no international rules regarding which medical supplies to bring when the nurseon- duty is called to emergencies outside a cruise ship's infirmary. Ideally, one First Response Bag should contain all that is needed to manage the initial 10-15 minutes of any medical emergency until the patient can be safely transported to the ship's infirmary. Royal Caribbean Cruises Ltd rece...

Purpose Energy groups are cargo owners with large amounts of energy sources (such as coal) to transport. To achieve a satisfactory tradeoff between the reliability requirements sea transportation process and need control investment cost, they usually set up self-owned fleet supplemented by chartered fleet. This paper aims investigate best structure evaluate scheme under volatile circumstances i...
