摘要 地震是一种极其严重的自然灾害。由于地震灾害救援密切关系到灾区人民的生命财产安全,关于灾后救援的科学调查研究因此也具有实践指导意义。搜救行动是一个需要合作的过程。探讨合作搜救的复杂特性,对指导救援行动意义重大。随机游走模型在众多领域中已经得到了广泛的应用。将随机游走模型中的一种,Lévy Flight引入到搜救模拟的研究中来,建立基于合作的搜救模型。基于初始救援物资有限的前提,将被困幸存者存活率这一因素加以考虑,提出了救灾物资这一概念,并与幸存者存活率相结合。探讨在初期物资有限的前提下,不同规模的救援队配置对救援工作开展的影响以及新的合作规则在救援中发挥的作用。结果表明,模型能在一定程度上描述灾后搜救过程,对加深搜救工作的理解及对策制定有一定的指导作用。 Earthquake is a terrible disaster. Since disaster relief has great impact on the safety of life and property, relevant research and study is of practical significance. Cooperation is indispensable in search and rescue (SAR) and understanding the character and complexity of cooperation in SAR is of vital importance. Based on the limitation of initial SAR materials, Levy Flight, a kind of Random Walk, in the study of SAR, established a SAR model based on cooperation is introduced. The effects of performance are scrutinized as the scale of rescue team change carefully with combination of survival rates with SAR materials. The results show that to some extent this SAR model are liable to describe the process of SAR and provides application value.
