基于ACP方法的新型冠状病毒肺炎疫情管控措施效果评估

open access: yes智能科学与技术学报, 2020
利用信息技术手段对疫情管控措施进行评估,从而指导管控措施的实施,对疫情防控具有理论和现实意义。基于ACP方法和统计数据构建了人工城市计算实验平台,建立了针对具体疫情管控的社区、学校、工厂3类典型场所的人工社会模型,通过计算实验对新型冠状病毒肺炎疫情的管控措施进行评估。结果发现,检验检疫、自我防护管控措施只能够延缓疫情中感染人数峰值的到来,对降低总感染人数的效果不明显,只有经济代价巨大的隔离措施能够显著地抑制疫情的发展。隔离措施的良好效果表明,有效阻断“人-人”传播链是疫情控制的关键环节 ...

社区疫情排查的智能优化调度方法

open access: yes智能科学与技术学报, 2020
在应对突发重大传染病时,社区防控是整个社会疫情防控的重要一环。在新型冠状病毒肺炎疫情社区防控实践经验的基础上,提出一个社区疫情排查调度问题的数学模型,根据相关疫情防控信息为社区重点住户估算风险指数,并在此基础上将重点住户分配给各个排查工作小组,为每个小组设定排查路线,从而尽可能高效地完成各项排查任务。为求解该问题,提出一种混合智能优化调度算法,它基于水波优化的启发式策略搜索解空间,并混合了两种局部搜索策略来提高解的精度,形成初步调度方案。在调度方案的实施过程中,如果排查到某个对象有特殊情况需要处置 ...
