Simulation-based emission calculation method for container terminal production operation system

Abstract

The emission calculation method based on actual energy data and mathematical analytical models have the disadvantages of time-consuming and high cost, and therefore it is necessary to study a system simulation-based method for calculating the emissions of container terminal production operation systems. This paper develops a simulation model of container terminal production operation systems based on the Arena simulation platform. Emission calculation formulas are embedded into the simulation model, which can calculate and output the energy consumption and emissions of ships and handling equipment. To validate the system simulation-based emission calculation method, a container terminal is taken as the research object and a series of simulation experiments are conducted. The main results show that (1) NOx is the main air pollutant and the CO2 and NOx emissions mainly come from ships, which are 90.7% and 80.4%, respectively, and (2) CO2 and NOx emissions during navigation of ships in the waterway are the main part of ship emissions and account for 60.7% and 53.9%, respectively.
