基于碳排放量的机型排班优化

Optimization of Airline Aircraft Scheduling Based on Carbon Emissions

绿色低碳是当今的发展要求。航空公司可以从优化机型排班工作作为突破口,实现减少碳排放量的目的。为计算多条航班计划碳排放量,采用国际民用航空组织(ICAO)碳排放量计算公式,针对某航A320和B737两种机型,以碳排放量最小为约束条件,使用CPLEX软件求出某个航段上机型的最优解,最终实现整个航段的碳排放量最小。结果显示,在航段上使用两种混合机型比使用单一机型可节约更多的碳排放量,碳排放的减少区间为0.6%~2.9%,证明从碳排放量优化航空公司机型具备一定的合理性。

Green and low-carbon is the requirement of today's development.Airlines can take the optimization of aircraft scheduling as a breakthrough to reduce carbon emissions.In order to calculate the planned carbon emissions of multiple flights,International Civil Aviation Organization(ICAO)carbon emission calculation formula is adopted.For two types of aircraft,A320 and B737,with the minimum carbon emissions as the constraint condition,CPLEX software is used to find the optimal solution of the aircraft on a certain flight segment,and ultimately achieve the minimum carbon emissions of the whole flight segment.The results show that the use of two hybrid aircraft types on the leg can save more carbon emissions than the use of a single aircraft type,and reduction range of carbon emissions is between 0.6%and 2.9%,which proved the rationality of optimizing airline models based on carbon emissions.
