Description

航段市场需求值的预测方法、装置及机器可读介质
本申请要求于2021年5月31日提交中国专利局、申请号为202110604809.5、发明名称为“航段市场需求值的预测方法、装置及机器可读介质”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及航空领域,尤其涉及一种航段市场需求值的预测方法、装置及机器可读介质。
背景技术
民航客运收益管理是航空公司运用预测和优化等科学手段对价格和座位进行管理,使得每一航班的每一航段的每个座位按不同的价格适时销售给不同类型的旅客,从而获得最大的收益;收益管理系统是利用航班计划、库存、离港与运价数据与信息,基于预测与优化模型,对未离港航班的库存进行自动管理的系统;未离港航班指定舱位的订座值预测指的是指定未离港航班在离港时的订座预测值,是收益管理系统的主要输出值。
收益管理系统的数据采集点与航段的距离港日期为一一对应关系,各航空公司在航班控制系统中设置国际、国内两套数据采集点;如果航班销售进度相对集中或预订期相对分散,航空公司可以根据自身航线网络特点设置数据采集点数量。
但是受限于收益管理工作的效率以及硬件性能,不能无限制的增加数据采集点的数据,这就导致了始终会有一些距航段离港日期与数据采集点不能一一对应,如何计算这些不能与数据采集点适配的距离港日期的市场需求值为目前亟待解决的问题。

首先对本申请实施例涉及的专用名词进行说明:
收益管理系统是指利用航班计划、库存、离港与运价数据,基于预测与优化模型,对未离港航班的库存进行自动管理的系统;
市场需求值是指旅客具有能力购买且具有实际购买需求的需求,可以产生实际的订单,可以不产生实际的订单,作为收益管理系统中的输出值;
距离港日期(Number of department days,Ndo),系统日期(也即当前日期)距航班航段离港日期的天数,例如当前日期为2021年4月26日,离港日期为2021年5月1日,该Ndo即为5天;
数据采集点(Data collection points,Dcp),由距离港日期而决定,与距离港日期为一一对应关系,例如:数据采集点Dcp 20对应距离港日期7天,其中,该数据采集点包括固定数据采集点Fixed-Dcp和浮动数据采集点Floating-Dcp,下面进行具体说明:
固定数据采集点Fixed-Dcp指的是狭义上的数据采集点,由距离离港天数确定,航空公司在航班控制系统中拥有国内航班航线与国际航班航线共计两套数据采集点规则;
浮动数据采集点Floating-Dcp:非固定数据采集点Fixed-Dcp范畴的数据采集点;例如:指定航班距离港日期为20天,但Dcp 11对应距离港日期为24天,Dcp 12对应距离港日期为18天,那么此数据采集点为浮动数据采集点,可标记为Dcp 11.5,当然也还可以为其他的数值,例如Dcp 11.2只要能将与浮动数据采集点相对应即可。
下面从航段市场需求值预测装置的角度本申请提供的航段市场需求值的预测方法进行说明,该航段市场需求值预测装置可以为服务器,也可以为服务器中的服务单元,具体不做限定。
请参阅图1,图1为本申请实施例提供的航段市场需求值的预测方法的一个流程示意图,包括:
101、确定目标航班的目标距离港日期。
本实施例中,航段市场需求值预测装置可以首先确定目标航班的目标距离港日期,该目标航班为目标航司中待预测市场需求值的航段,例如该目标航班的离港日期为2021年5月10日,当前日期为2021年4月26日,则可以确定该目标航班的目标距离港日期为14天。可以理解的是,此处以距离港日期为例进行说明,当然也还可以是其他的计数单位,例如时刻,具体不做限定。可以理解的是,航段是指能够构成旅客航程的航段,例如该第一航班为北京-上海-旧金山所对应的航班,旅客航程有3种可能:北京-上海、上海-旧金山和北京-旧金山,也即该第一航班包括北京-上海航段、上海-旧金山航段和北京-旧金山航段,共3个航段。
102、根据目标航段所对应的数据采集点信息判断目标距离港日期所对应的数据采集点是否为浮动数据采集点,若目标距离港日期所对应的数据采集点为浮动数据采集点,则执行步骤103。
本实施例中,航段市场需求值预测装置可以根据目标航段所对应的数据采集点信息判断目标距离港日期所对应的数据采集点是否为浮动数据采集点,下面对判断的过程进行具体说明:
航段市场需求值预测装置可以首先获取目标航司(也即指定航空公司)的数据采集点信息,该数据采集点信息包含如下:数据采集点数据,如:Dcp(1)、Dcp(2)、Dcp(3)、……、Dcp(j)、……、Dcp(23)以及Dcp(24),该数据采集点分别对应未离港航班的距离港日期,如:Ndo[Dcp(1)]=180,Ndo[Dcp(2)]=120,Ndo[Dcp(3)]=90,……,Ndo[Dcp(j)]=n,……,Ndo[Dcp(23)]=0,Ndo[Dcp(24)]=-1;之后根据目标航段所对应的数据采集点信息确定目标航段所对应的历史航段集合,该历史航段集合中的每个航段分别与数据采集点中的距离港日期相对应,也就是说在确定目标航段之后,可以确定与该目标航段相对应的数据采集点信息,进而可以根据该数据采集点信息确定与该目标航段相对应的历史航段集合中每个历史航段的航段数据。
之后航段市场需求值预测装置可以获取历史航段集合中每个历史航段所对应的距离天数,并判断该目标距离港日期是否与每个历史航段所对应的距离港日期是否匹配,若不匹配,则确定该目标距离港日期所对应的数据采集点为浮动数据采集点。例如该固定数据采集点所对应的距离港日期为1,4,8,10,14,18,22,……,365,该目标距离港日期为20天,与该固定采集点所对应的距离港日期并不匹配,则确定该目标距离港日期所对应的数据采集点为浮动数据采集点。
需要说明的是,该数据采集点信息还包括以下数据中的至少之一:航班号、始发机场、达到机场、航班航段离港日期与时刻、航班航段各舱位订座值与对应运价值。
103、若目标距离港日期所对应的数据采集点为浮动数据采集点,则根据浮动数据采集点确定目标航段所对应的第一固定数据采集点以及第二固定数据采集点。
本实施例中,航段市场需求值预测装置在确定目标距离港日期所对应的数据采集点为浮动数据采集点时,可以根据浮动数据采集点确定该目标航段所对应的第一固定数据采集点以及第二固定数据采集点,具体的首先确定与浮动数据采集点相邻的两个固定数据采集点,之后将与浮动数据采集点相邻的两个固定数据采集点分别确定为第一固定数据采集点以及第二固定数据采集点,例如该目标距离港日期为20天,固定数据采集点Dcp 11对应距离港日期为24天,固定数据采集点Dcp 12对应距离港日期为18天,则可以确定该固定数据采集点Dcp 11为第一固定数据采集点,该固定数据采集点Dcp 12为第二固定数据采集点,或者,该固定数据采集点Dcp 11为第二固定数据采集点,该固定数据采集点Dcp 12为第一固定数据采集点。
104、获取第一固定数据采集点所对应的第一采集点数据以及第二固定数据采集点所对应的第二采集点数据。
本实施例中,航段市场需求值预测装置在确定第一固定数据采集点以及第二固定数据 采集点之后,可以从本地数据库中获取第一固定数据采集点所对应的第一采集点数据以及第二固定数据采集点所对应的第二采集点数据,该本地数据库中存储有包括第一固定数据点以及第二固定数据采集点在内的多个数据采集点所对应的采集点数据,其中,该采集点数据包括该固定数据采集点所对应的市场需求值、该固定数据采集点的距离港日期以及航段数据,该市场需求值为该目标航段在该固定采集点所对应的距离港日期的市场需求值。此处具体不限定确定该市场需求值的方式,例如,获取目标航司的指定航班的航班信息,基于航班信息获取库存数据,该库存数据具体包括已离港航班库存信息和未离港航班库存信息,其中,已离岗航班库存数据为指定航班以当前日期为基准的过往三年的已离港航班的航班库存数据,未离港航班的库存数据为指定航班在当前日期为基准的未来一年的航班库存数据;根据库存数据判断指定航班的指定舱位的销售状态。根据目标航司所对应的数据采集点,指定航空公司的航班信息、指定航班的库存数据等来识别指定航班的指定舱位的销售状态,销售状态包括锁舱、开舱等,最后基于预设算法对销售状态进行处理,得到指定航班的市场需求值。
需要说明的是,当指定舱位的可利用座位数小于等于零,可利用状态为开放、关闭,说明指定舱位处于非可销售状态,即为锁舱;指定舱位的可利用座位数大于零,可利用状态为关闭,说明指定舱位处于非可销售状态;即为锁舱;指定舱位的可利用座位数大于零,可利用状态为开放,说明指定舱位处于可销售状态;即为开舱;
下面对如何基于预设算法对销售状态进行处理,得到指定航班的时长需求值进行说明:
如果数据采集点DCP(n+1)的销售状态为开舱,且数据采集点DCP(n)的销售状态为开舱:
若数据采集点(n)较数据采集点(n+1)订座数是增加的,则使用如下公式计算数据采集点DCP(n+1)的市场需求值计算:
市场需求值DCP(n+1)=市场需求值DCP(n)+订座值增加变动值DCP(n),其中,订座增加变动值=实际订座值DCP(n+1)-实际订座值DCP(n)。
若数据采集点(n)较数据采集点(n+1)订座数是减少的,则通过如下公式计算数据采集点DCP(n+1)的市场需求值:
市场需求值DCP(n+1)=市场需求值DCP(n)+订座减少变动值DCP(n),其中,订座减少变动值=(实际订座值DCP(n+1)x市场需求值(n))/实际订座值DCP(n)-市场需求值(n)。
若数据采集点DCP(n+1)的销售状态为锁舱,且数据采集点DCP(n)的销售状态为开舱:
当数据采集点(n)较数据采集点(n+1)订座数是减少时,则通过如下公式计算:
市场需求值DCP(n+1)=市场需求值DCP(n)+订座减少变动值DCP(n),其中,订座减少变动值=(实际订座值DCP(n+1)x市场需求值(n))/实际订座值DCP(n)-市场需求值(n)。可以理解的是,上述市场需求值的计算是一个迭代的过程,即为DCP(1)的市场需求值等于实际订座值,迭代计算DCP+=1的市场需求值。
也就是说,该目标航班所对应的各固定采集点的市场需求值,本地数据库中是有存储的,可以提前计算出目标航段在各个固定数据采集点的市场需求值,并将该市场需求值与该目标航段的航段数据作为一个信息对存储至本地数据库中,在需要用到时,直接从本地数据库获取即可。
105、根据目标距离港日期、第一采集点数据以及第二采集点数据确定目标航段在目标距离港日期的市场需求值。
本实施例中,该第一采集点数据包括第一距离港日期以及第一市场需求值,第二采集点数据包括第二距离港数据以及第二市场需求值,具体的,可以通过如下公式,计算目标航段在目标距离港日期的市场需求值:
Figure PCTCN2022087048-appb-000002
其中,Demand(Floating-DCP)为所述目标航段在所述目标距离港日期的市场需求值,Demand DCP(j)为所述第一市场需求值,Demand DCP(j-1)为所述第二市场需求值,Ndo(j)为所述第一距离港日期,Ndo(j-1)为所述第二距离港日期,Ndo(Floating-DCP)为所述目标距离港日期。
综上所述,可以看出,本申请提供的实施例中,通过确定目标航段的目标距离港日期,并根据目标航段所对应的数据采集点判断该目标距离港日期所对应的数据采集点是否为浮动数据采集点,若是,则确定第一固定数据采集点以及第二固定数据采集点,并根据第一固定数据采集点的采集点数据以及第二固定数据采集点的采集点数据确定目标航段在目标距离港日期的市场需求值,相对于现有的通过增加固定数据采集点的方式来确定目标航段在距离港日期的市场需求值来说,由于本申请中无需增加额外的固定数据采集点,可以提升收益管理工作的效率。
