Application of Discrete Event Simulation in Measuring Pollutant Emissions: A case study for London Heathrow (LHR)
نویسندگان
چکیده
The aim of this paper is to explain the relationship between air pollutant-emissions and waiting times whilst aircrafts queue to access London Heathrow (LHR) runways. The approach to this problem is to develop a discrete-event simulation that describes the current landing and take-off operations, aircraft inter-arrivals and inter-departures, runway utilisation, and average waiting times for the aircrafts to access the runways. The proposed models cover three runway operational scenarios: segregated mode, mixed mode and mixed mode with third runway. The produced stochastic model will then estimate the average number of approaching aircrafts awaiting resources for access to runways (analogous to work-in-process in manufacturing environments). The emission estimation model takes into consideration the number of aircrafts at different altitudes and on land, and relates the information to the average emission for each aircraft at each state.

One of the main controlling parameters in diesel engine combustion is the fuel – air mixing process that has direct effects on engine performance and pollutant emissions, reviewing over previous literature showed that split injection strategies could satisfy this purpose very well. For the first time and in this paper, pilot and double injection strategies were combined and formed new triple in...
متن کاملA discrete-event optimization framework for mixed-speed train timetabling problem
Railway scheduling is a complex task of rail operators that involves the generation of a conflict-free train timetable. This paper presents a discrete-event simulation-based optimization approach for solving the train timetabling problem to minimize total weighted unplanned stop time in a hybrid single and double track railway networks. The designed simulation model is used as a platform for ge...
متن کاملSources of sub-micrometre particles near a major international airport
The international airport of Heathrow is a major source of nitrogen oxides, but its contribution to the levels of sub-micrometre particles is unknown and is the objective of this study. Two sampling campaigns were carried out during warm and cold seasons at a site close to the airfield (1.2 km). Size spectra were largely dominated by ultrafine particles: nucleation particles (< 30 nm) were foun...
