在本公开实施例中,人员流动概率,表征单元格之间的人员流动情况。其中,区域内感染人员分布的评估装置执行步骤103的过程可以参考图4所示,在图4中,步骤103具体可以包括以下步骤:
S1031、针对每个单元格,根据各个时间窗口内单元格内人员的标识与各个时间窗口内每个其他单元格内人员的标识,确定历史时间段内单元格与每个其他单元格的共同存在人员数量。
在本公开实施例中,历史时间段内时间窗口的数量可以为n个。由于单元格之间人员的流动是需要时间的,人员不会在同一时间点同时位于两个单元格内,也难以很短的时间内从一个单元格转移到另一个单元格。因此,区域内感染人员分布的评估装置执行步骤1031的过程例如可以为,针对每个单元格,对历史时间段内前n-1个时间窗口内单元格内人员的标识,进行并集处理,得到单元格的第一并集结果;针对每个其他单元格,对历史时间段内后n-1个时间窗口内其他单元格内人员的标识进行并集处理,得到其他单元格的第二并集结果;对单元格的第一并集结果与每个其他单元格的第二并集结果进行交集处理,根据交集处理后的人员的标识的数量,确定历史时间段内单元格与每个其他单元格的共同存在人员数量。
在本公开实施例中,以n为5,单元格用(i,j)表示,单元格的人员属性信息用ld(i,j)表示,第n个时间窗口内单元格的人员属性信息用ldtn(i,j)表示,第n个时间窗口内其他单元格的人员属性信息用ldtn(p,k)表示,则历史时间段内单元格(i,j)与其他单元格(p,k)的共同存在人员数量的计算公式可以为,
历史时间段内单元格(i,j)与其他单元格(p,k)的共同存在人员数量=Q((ldt1∪ldt2∪ldt3∪ldt4)(i,j)∩(ldt2∪ldt3∪ldt4∪ldt5)(p,k))。
S1032、获取单元格的总存在人员数量,总存在人员数量为各个时间窗口内单元格内存在过的人员的总数量。
在本公开实施例中,以上述例子进行说明,单元格的总存在人员数量可以为5个时间窗口内单元格内存在过的人员的总数量。另外,由于单元格之间人员的流动是需要时间的,第5个时间窗口内单元格的人员属性信息对人员流动概率的计算并未提供贡献,因此,为 了进一步提高人员流动概率计算的准确度,可以结合前n-1个时间窗口内单元格的人员属性信息进行人员流动概率的计算,以n为5为例,单元格的总存在人员数量的计算公式可以为,
单元格的总存在人员数量=Q((ldt1∪ldt2∪ldt3∪ldt4)(i,j))。
S1033、根据单元格与每个其他单元格的共同存在人员数量以及总存在人员数量,确定单元格至每个其他单元格的人员流动概率。
在本公开实施例中,以上述例子进行说明,以n为5为例,单元格(i,j)至其他单元格(p,k)的人员流动概率的计算公式可以为,
R(i,j),(p,k)=Q((ldt1∪ldt2∪ldt3∪ldt4)(i,j)∩(ldt2∪ldt3∪ldt4∪ldt5)(p,k))/Q((ldt1∪ldt2∪ldt3∪ldt4)(i,j))
其中,R(i,j),(p,k)表示单元格(i,j)至其他单元格(p,k)的人员流动概率。
S104、针对每个待处理单元格,根据待处理单元格的当前人员感染信息、待处理单元格至每个其他单元格的人员流动概率、每个其他单元格至待处理单元格的人员流动概率、以及预设的传染病模型,评估时间窗口后待处理单元格的人员感染信息。
在本公开实施例中,待处理单元格的当前人员感染信息可以包括:单元格内人员的标识以及感染状态;结合待处理单元格内人员的标识以及感染状态,以及预设的传染病模型,就能够评估待处理单元格在时间窗口内的第一人员感染变动信息;结合待处理单元格的当前人员感染信息、待处理单元格至每个其他单元格的人员流动概率、以及每个其他单元格至待处理单元格的人员流动概率,就能够评估待处理单元格与其他单元格之间的第二人员感染变动信息;结合第一人员感染变动信息、第二人员感染变动信息以及当前人员感染信息,就能够确定时间窗口后待处理单元格的人员感染信息。
S105、根据时间窗口后各个待处理单元格的人员感染信息,确定时间窗口后待处理区域内的感染人员分布。
在本公开实施例中,步骤105之后,区域内感染人员分布的评估装置还可以执行以下过程:获取待处理区域内各个位置的防护救治资源;根据待处理区域内各个位置的防护救治资源,以及时间窗口后待处理区域内的感染人员分布,对待处理区域的防护救治资源进行调配处理。
本公开实施例的区域内感染人员分布的评估方法,通过获取待处理区域,以及对待处理区域进行网格划分得到的多个单元格;获取历史时间段的各个时间窗口内各个单元格的人员属性信息,其中,人员属性信息包括:单元格内人员的标识;根据各个时间窗口内各个单元格内人员的标识,确定各个单元格至每个其他单元格的人员流动概率;针对每个待 处理单元格,根据待处理单元格的当前人员感染信息、待处理单元格至每个其他单元格的人员流动概率、每个其他单元格至待处理单元格的人员流动概率、以及预设的传染病模型,评估时间窗口后待处理单元格的人员感染信息;根据时间窗口后各个待处理单元格的人员感染信息,确定时间窗口后待处理区域内的感染人员分布,从而通过对区域进行网格划分得到多个单元格,而不是以个体为单元格,根据时间窗口后单元格内以及单元格间的人员感染变动信息,确定时间窗口后各个待处理单元格的人员感染信息,计算量小,消耗的计算资源小,计算速度快。
图5为本公开实施例提供的另一种区域内感染人员分布的评估方法的流程示意图。如图5所示,在图1所示实施例的基础上,步骤104具体可以包括以下步骤:
S1041、根据待处理单元格的当前人员感染信息以及预设的传染病模型,评估时间窗口内单元格内的第一人员感染变动信息。
区域内感染人员分布的评估装置执行步骤1041的过程例如可以为,获取每个其他单元格的当前人员感染信息以及当前人员数量;根据待处理单元格的当前人员感染信息,确定待处理单元格的当前人员数量;结合待处理单元格的当前人员感染信息和当前人员数量、每个其他单元格的当前人员感染信息以及当前人员数量、以及预设的传染病模型,评估时间窗口内单元格在人员流动情况下的第一人员感染变动信息。
在本公开实施例中,在第一种实施场景中,待处理单元格的当前人员数量,可以为待处理单元格的当前人员感染信息中人员标识的数量。在第二种实施场景中,待处理单元格的当前人员数量,可以结合前一时间窗口中待处理单元格的人员数量、各个时间窗口内待处理单元格以及其他单元格的人员属性信息来确定。其中,待处理单元格的当前人员数量的计算公式例如可以如以下公式所示。

是指转移出待处理单元格(i,j)的人员数量。
在本公开实施例中,传染病模型,主要研究传染病的传播速度、空间范围、传播途径、动力学机理等问题,以指导对传染病的有效地预防和控制。其中,待处理单元格的当前人 员感染信息可以包括:单元格内人员的标识以及感染状态。其中,人员的感染状态可以分为4种,易感者,潜伏者,感染者和康复者。其中,易感者可以用S表示,潜伏者可以用E表示,感染者可以用I表示,康复者可以用R表示。
其中,易感者与潜伏者之间的转移概率可以用α表示,阿尔法一般与单元格内部感染者的密度相关,感染者的密度为单元格内感染者的数量与单元格内人员数量的比值。潜伏者与感染者之间的转移概率β,以及感染者与康复者之间的转移概率γ,与传染病的传播参数相关。
在本公开实施例中,在第一种实施场景中,传染病模型可以不考虑单元格间的人员流动情况,只基于动力学微分方程以及上述3个转移概率,结合输入的单元格内当前的易感者数量、潜伏者数量、感染者数量和康复者数量,来预测时间窗口后单元格内各种感染状态的人员的变动信息。其中,传染病模型结合以下公式来预测时间窗口后单元格内各种感染状态的人员的变动信息。

在本公开实施例中,在第二种实施场景中,传染病模型考虑单元格间的人员流动情况,基于动力学微分方程、上述3个转移概率以及单元格间的人员流动情况,结合输入的单元格内当前的易感者数量、潜伏者数量、感染者数量和康复者数量,来预测时间窗口后单元格内各种感染状态的人员的变动信息。其中,传染病模型结合以下公式来预测时间窗口后单元格内各种感染状态的人员的变动信息。
