A system utilizing computer simulations was developed in order to compare (1) situations wherein critically wounded individuals are, at first, ranked and classified into subgroups based on criticalness of the wounds, and then be evaluated and re-ordered within the subgroups before transported to hospitals, with (2) those situations in which the conventional method of transport was employed. The objective of the study is to infer whether there is a further possibility for enhancing the possibility of the wounded individual's survival rate at the time of arrival at the hospital. The variables that are required to be entered include the number of patient subgroups, the number of patients in each of the subgroups, the total number of patients to be transported, the time required to assess the severity of each patient, the speed of the ambulance, the interval between the ambulances' arrivals and departures, and the distance between the site at which the transportation begins and the destination or the hospital. Utilizing the same system, a virtual simulation of a large-scale disaster at airport was used as sample data. As a result, it was confirmed that the survival rate would improve under certain conditions, if the values for some of the variables, such as geographic conditions, were altered and then calculated.
开发了一个利用计算机模拟的系统，以便比较：(1) 重伤员首先根据伤口的严重程度进行排序并分成亚组，然后在转运至医院之前在亚组内进行评估并重新排序的情况，与 (2) 采用传统转运方法的情况。该研究的目的是推断在伤员到达医院时提高其存活率的可能性是否还有进一步提升的空间。需要输入的变量包括患者亚组的数量、每个亚组中的患者数量、要转运的患者总数、评估每个患者严重程度所需的时间、救护车速度、救护车到达和离开的间隔时间，以及运输开始地点与目的地或医院之间的距离。利用同一系统，将机场大规模灾难的虚拟模拟用作样本数据。结果证实，如果改变并计算某些变量的值，如地理条件等，在某些条件下存活率会提高。
