Embodiment

[0050] See figure 1 , figure 1 It is a flow chart of a simple method for selecting the best location for placing medical rescue materials and the best rescue route disclosed in the present invention.

[0051] The inventive method is described in detail below:

[0052] 1. Assumed test conditions

[0053] First, divide the rescue large area system into several small area points Q p {p=1,2,3,4,5,...n}, n=6 in this embodiment, namely Q p {p=1, 2, 3, 4, 5, 6};

[0054] Collect the population of different small areas R p {p=1, 2, 3, 4, 5, 6}, from the area point Q p to area point Q q The shortest distance d pq 、 After considering the influence of surrounding road factors, the ambulance will pq The corresponding different speed v on pq , the quantity m of rescue supplies (ambulances), and the stipulated time τ to arrive at the rescue site;

[0055] Normalization processing: the distance d between different regions pq Corresponding to different speeds v pq Normalized to t...

Embodiment 2

[0095] 2. There is 1 ambulance

[0096] 2.1. Model analysis

[0097] When only one ambulance can be arranged, according to the above data, it is difficult for one ambulance to arrive at the location of the residents who received the call within 8 minutes and cover six areas, so that as many people as possible can call for help. Can be reached within 8 minutes, ie T min ij ≤8min, and make the area where j satisfies the largest population.

[0098] 2.2. Model solution

[0099] No matter which area an ambulance is parked in, the ambulance cannot reach all the calling areas in the city within 8 minutes.

[0100] Table 5-Relationship between ambulance location and the number of people who cannot be covered

[0101]

[0102] Express the data shown in Table 5 with a histogram, such as image 3 shown. From Table 5 and image 3 It can be seen that although no matter where the ambulance is parked, any j€{1, 2, 3, 4, 5, 6} cannot be made, so that T minij ≤8min is always establ...

Embodiment 3

[0105] 3. Extraordinary rescue situations

[0106] 3.1. Model analysis

[0107] Average weighted shortest time for the three ambulances to reach the disaster area:

[0108] Z j - min = Σ i = 1 3 T i 3 , j = 1,2,3,4,5,6

[0109] Among them, Ti represents the shortest time for one of the three ambulances to reach the disaster area.

[0110] The average personal ambulance travel time in the whole city corresponding to the shortest average weighted time of the selected site:

[0111] T = Σ j = 1 ...

Abstract

The invention discloses a method for selecting the optimal emergency medical care reaction path in comprehensive consideration of rescuing materials and region rescuing importance. According to the method, a region system to be rescued is divided into multiple region points Qp, then information parameters of all the region points Qp are collected, the shortest distance dpq between different regions is processed into the reference quantity Spq of time in a normalization mode through corresponding different speeds vpq, the minimum rescuing time Tmin of all paths is solved, then time Tmin of all the paths is compared with regulated time tao for reaching the rescuing place to obtain all rescuing schemes F{F1, F2, F3,...Fs} under the condition that the number of the rescuing materials is m, and in comprehensive consideration of sufficient rescuing materials, insufficient rescuing materials and importance difference of regions, the optimal emergency medical care path and the selected site of the rescuing materials are provided. In this way, the rescuing capacity and efficiency of different regions are improved.

Description

technical field [0001] The invention relates to the field of medical emergency response management, in particular to a method for selecting an emergency medical response path. Background technique [0002] In the past 10 years, natural disasters have occurred frequently in our country, which has caused adverse effects on the physical and mental health of our people and economic development. For example, at 12:00 on September 18, 2008 in my country, the Wenchuan Earthquake caused a total of 69,227 deaths, 374,643 injuries, and 17,923 missing persons, causing direct economic losses of 845.2 billion yuan. The most direct way to improve the effect of rescue and reduce property loss and casualties is to choose the best rescue plan. [0003] Choosing the best rescue plan is the primary issue that needs to be considered in the face of various emergencies, and the best rescue plan is often closely related to the location of the ambulance. Under emergency conditions, the ambulance ...
