Description

Technical Field

[0001] The present invention relates to the technical field of software development, and in particular to a multi-department emergency plan joint deduction simulation system for emergency events. Background Art

[0002] With the deepening of globalization and urbanization, the frequency and scope of various emergencies are increasing, posing a serious threat to people's lives and property. Improving emergency response capabilities has become a top priority. Emergency drills, as a key means of improving emergency response capabilities, can effectively enhance the joint implementation of emergency plans among various departments.

[0003] Some existing emergency response plan simulation systems use web-based media to provide basic knowledge training and case studies for frontline personnel. Other emergency event simulation systems focus on multi-person collaborative operations and specialized skills training for rescue personnel. Existing emergency event simulation systems primarily focus on practical simulation training for frontline personnel, with relatively little training for joint emergency response plan simulations for decision-makers from multiple departments. Furthermore, practical simulation training for frontline personnel is not significantly effective in improving the joint emergency response plan simulation training for decision-makers from multiple departments. Furthermore, there is relatively little training for collaborative emergency response plan simulations and responses between departments. Summary of the Invention

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] This embodiment introduces a multi-department emergency plan joint simulation system for emergency events, such as Figure 1 As shown,

[0037] The system architecture of the present invention mainly includes: a login module, a plan setting module, an emergency event setting module, a plan deduction module, an expert evaluation module and a desktop deduction real-time display module.

[0038] The login module includes a coach login terminal, a trainer login terminal and an evaluation expert login terminal;

[0039] The coach login terminal is used for the coach to log in to the simulation system to determine emergency events and issue task instructions;

[0040] The training personnel login terminal is used for the training personnel to log in to the simulation system and select the simulation department to which the training personnel belongs and receive the task instructions;

[0041] The evaluation expert login terminal is used for the evaluation expert to log in to the deduction simulation system to evaluate the deduction results.

[0042] Specifically, the login module of this embodiment is used by trainers, coaches, and assessment experts to log in and out of the simulation system. Coaches use the login module to select and determine the emergency event for which they will conduct a contingency plan simulation. Trainers use the login module to select their simulation department and receive task instructions. The emergency event selected by the coach for the contingency plan simulation requires trainers from multiple simulation departments to jointly conduct simulations, and trainers from multiple simulation departments must simultaneously conduct subsequent simulations according to the task instructions.

[0043] like Figure 2 The operational flow of this embodiment is shown as follows: the first step is for the trainer, coach and evaluation expert to log in to the login module; the coach selects the emergency event to be simulated, and the system automatically loads the static process of the emergency event; then the coach sets the risk coefficient of the emergency event, the type and number of dangerous molecules in the emergency event, the type and number of personnel available in different departments and other parameters through the emergency event setting program; then the coach can set the emergency plans that can be used by each department, the impact parameters of the types and number of emergency plan jobs on the emergency event through the plan setting program; after logging in, the trainer selects the department for joint simulation and sends the selection result to the plan simulation program; after entering the evaluation expert system, the evaluation expert can set the evaluation parameters, and finally generate an evaluation strategy configuration file and send it to the simulation performance evaluation program.

[0044] The emergency event setting module is used to issue an emergency event instruction after the coach logs into the simulation system, and set the emergency event parameters of the simulation department according to the emergency event instruction;

[0045] Preferably, the emergency event parameters of the simulation department include the types of supplies available to the training personnel of the simulation department, the maximum quantity of these supplies, the types of personnel available to the training personnel of the simulation department, the maximum number of personnel for each type of personnel, the risk factor of the emergency event, the number of dangerous individuals (those who cause the emergency event), and the initial evolution speed of the emergency event. Specifically, the emergency event setting module can generate an emergency event parameter configuration file based on the set emergency event parameters.

[0046] The emergency plan setting module is used to set the emergency plan parameters of the simulation department according to the emergency event instruction after the coach logs into the simulation system;

[0047] Preferably, the emergency plan parameters of the simulation department include: the type of emergency plan, the type of work required for the type of emergency plan, the minimum number of people corresponding to the type of work required for the type of emergency plan, the type of materials required for the type of emergency plan, and the minimum number of emergency materials corresponding to the type of materials required for the type of emergency plan; the impact parameters of the type of work required for the type of emergency plan and the number of people corresponding to the type of work required for the type of emergency plan on emergency events, the impact parameters of the type of materials required for the type of emergency plan and the number of emergency materials corresponding to the type of materials required for the type of emergency plan on emergency events, the impact parameters of the type of emergency plan on the evolution of emergency events, and the impact parameters of the emergency plan type of the simulation department on other simulation departments and plans; specifically, the plan setting module can generate an emergency plan parameter configuration file based on the set emergency plan parameters.

[0048] The emergency plan simulation module is used for the training personnel to set the emergency plan type according to the simulation department to which the training personnel belongs, and to set the actual parameters of the simulation process according to the emergency event parameters of the simulation department, so as to obtain the emergency event evolution coefficient and thus obtain the emergency plan evolution speed;

[0049] In order to achieve that when the emergency event reaches the emergency event evolution condition (evolution speed is greater than or equal to the emergency event threshold), the training personnel reset the type of emergency plan to deduce the emergency event that reaches the emergency event evolution condition; or when the emergency event reaches the set emergency event end condition, the deduction process of the emergency event is completed. Figure 3 As shown;

[0050] Preferably, the emergency event evolution coefficient is obtained as follows:

[0051] a t+1 =a t +ES×T step

[0052]

[0053]

[0054] Where: a t+1 represents the evolution coefficient of the emergency event in the t+1 time period; a t represents the evolution coefficient of the emergency event in the tth time period; ES represents the actual evolution speed of the emergency event; T step Indicates the time step; ES init Indicates emergency events; N y Indicates the total number of plans; i indicates the plan number; ES Yi represents the impact parameter of plan i on the emergency event; t represents the time period number; represents the total number of material types included in plan i; j represents the number of material types used; represents the quantity of the jth material used in plan i; It represents the parameter that affects the evolution speed of each unit of the j-th material in plan i; Indicates the total number of types of work included in plan i; represents the number of workers in the oth type of work used in plan i; It represents the parameter of influence of each worker in the oth type of work used in plan i on the material evolution speed; o represents the number of the type of work;

[0055] Specifically, the emergency plan simulation module is responsible for real-time simulation of emergency plan parameters. It initializes the emergency plan simulation program based on the emergency event parameter configuration file, the emergency plan parameter configuration file, and the input emergency event options, and performs implementation simulation based on the input of the training personnel to implement the emergency plan. The training personnel need to implement the emergency plan according to the emergency event and deploy the corresponding manpower and material resources. Based on the emergency plan and related parameter inputs, the module simulates the emergency event in real time according to the emergency event parameter configuration file and the emergency plan parameter configuration file, and calculates the emergency event simulation coefficient. If the emergency event meets the end condition, the emergency plan simulation ends and the generated plan simulation results are sent to the expert evaluation module. If the emergency event meets the evolution condition, a new emergency event will occur.

[0056] Preferably, the emergency plan evolution conditions are:

[0057] ET≤ES

[0058] Where: ET represents the emergency event evolution threshold; ES represents the emergency event evolution speed;

[0059] Specifically, the emergency plan termination conditions in this embodiment are:

[0060]

[0061] Where NumJ is the total number of end conditions, J is the number of the judgment condition, and f(J) is the parameter representing the Jth judgment condition of the real-time calculation of the current emergency event. This parameter is unique and is calculated differently for different events. The calculation formula for the judgment condition parameter is as follows:

[0062]

[0063] Specifically, in the subway fire case, the total number of judgment conditions NumJ = 2, where:

[0064] The conditions for achieving the judgment of f(1) are:

[0065] Da+Dr=NumD

[0066] Where: Da is the number of suspects captured, Dr is the number of dangerous elements who have escaped, and NumD is the number of dangerous elements in the emergency event set by the coach.

[0067] The judgment condition for f(2) to be met is:

[0068] F ≤ 0 or F ≥ 2D

[0069] Where: F is the fire parameter. If F ≤ 0, the fire is extinguished. If F ≥ 2, the fire spreads and cannot be controlled. Specifically, when 0 < F ≤ 2, it is in a state where the judgment condition is not met, and at this time, the training personnel normally conduct deductions for the emergency event.

[0070] The expert evaluation module is used to obtain the total number of plans executed at the end of the emergency event and the actual parameters of the deduction process when the emergency event meets the end condition, including the number of work types for each plan, the number of people for each work type, the types of materials used for each plan, and the quantity of each type of material, and the evaluation personnel determine the evaluation parameters to obtain the joint deduction score of each department;

[0071] Specifically, the evaluation parameters include: the proportion parameter of the plan execution score of the deduction department, the proportion parameter of the deduction parameter score of the deduction department, the subjective score of the expert system of the deduction department, etc.

[0072] Specifically, the expert evaluation module is responsible for evaluating the results of the emergency event deduction. Experts can enter this module through logging in to the system to change the evaluation settings and generate an evaluation strategy configuration file. This module calculates the emergency plan deduction score based on the input plan deduction results and the evaluation strategy configuration file. The calculation of the emergency plan deduction score includes the calculation of the proportion of the emergency plan score and the calculation of the proportion of the deduction parameters, and finally generates the plan deduction score. As Figure 4 shown;

[0073] Preferably, the joint deduction score of the deduction department is obtained as follows:

[0074]

[0075] G b = Gy b × Gyper b + Gt b × Gtper b + Gsub b

[0076] Where: Gy b represents the emergency plan execution score of the bth deduction department; NumY b represents the total number of emergency plans executed by the bth deduction department; i represents the plan number; represents the score of the bth simulation department in executing the ith emergency plan (set by the expert system); represents the execution efficiency score of the bth simulation department in executing the i-th emergency plan; The score of the bth simulation department for executing the type and quantity of work assigned in the ith emergency plan; The score of the input materials and quantity of the b-th simulation department in implementing the i-th emergency plan; Gt represents the total score of the bth simulation department in executing the i-th emergency plan; b Indicates the deduction results of the b-th deduction department; NumT b represents the total number of actual parameters of the simulation process of the bth simulation department; The score representing the actual parameters of the p-th group of simulation process in the b-th simulation department (set by the expert system); represents the maximum value of the actual parameter of the p-th group of the b-th deduction department; The maximum score coefficient of the actual parameter of the p-th group of deduction process in the b-th deduction department; The actual parameters of the simulation process at the end of the simulation of the bth simulation department; The score coefficient of the actual parameter of the simulation process at the end of the simulation of the b-th simulation department; G represents the total score of the actual parameters of the b-th deduction department's deduction process; b Indicates the joint deduction results of the b-th deduction department; Gyper b Gtper represents the performance ratio parameter of the bth simulation department (set by the expert system); b Gsub represents the performance ratio of the bth deduction department (set by the expert system); b represents the expert system subjective score of the b-th deduction department (set by the expert system);

[0077] Preferably, the joint deduction simulation system of this embodiment further includes a desktop deduction real-time display module; the desktop deduction real-time display module is used to display the deduction process of emergency events in real time.

[0078] Specifically, this embodiment is based on 3DMax modeling, unity3D virtual reality development engine, and is developed and produced using C# language. The simulation system architecture of this embodiment mainly includes: login module, plan setting module, emergency event setting module, plan simulation module, expert evaluation module and desktop simulation real-time display module. Figure 2 shown.

[0079] Specifically, during implementation, emergency events and joint simulation departments are determined, and then static processes for emergency events are formulated. Emergency plans and impact parameters for the events are formulated based on the responsibilities of different departments. 3Dmax is used to create models of relevant environments, characters, equipment, etc. for emergency events, and these are imported into the Unity3D engine via FBX format for real-time rendering. At the same time, C# programming is used to implement the emergency event simulation process. When the system enters the simulation program, Figure 3 The simulation program shown initializes the emergency event simulation program through the acquired emergency event parameter configuration file, static emergency event process and emergency plan parameter configuration file. During the initialization, the emergency event plan simulation program dynamically modifies the static emergency event process simulation parameters according to the emergency event parameter configuration file and the emergency plan parameter configuration file, and at the same time initializes the emergency event plan desktop simulation real-time display program scene. Students from various departments can view the emergency event plan simulation status and emergency event virtual scene in real time.

[0080] The plan simulation program then enters the emergency event plan simulation calculation stage. In this stage, the plan simulation program performs calculations based on the emergency plans and related parameters arranged by each department. The emergency plans and related parameters arranged by each department are input by the trainees, including the implemented emergency plans, the types of work and number of people arranged by the emergency plans, and the materials and quantities arranged by the emergency plans.

[0081] During the emergency plan simulation calculation stage, the emergency event simulation coefficient and the emergency event evolution coefficient are calculated. The emergency event simulation coefficient and the emergency event evolution coefficient are calculated based on the emergency plan and related parameter inputs and the current status of the emergency event. When the emergency event evolution coefficient reaches the emergency event evolution condition, a new emergency event is evolved. If the emergency event simulation coefficient reaches the emergency event end condition, the emergency plan simulation ends, and the plan simulation results are output and sent to the simulation performance evaluation program.

[0082] When the system enters the evaluation process, such as Figure 4 As shown, the simulation results are evaluated based on the plan simulation results output by the plan simulation program and the evaluation strategy configuration file generated by the evaluation setting module. The plan simulation results include emergency event casualty parameters, emergency event evolution parameters, multi-department joint coordination parameters, emergency event simulation efficiency parameters, plan simulation resource call parameters and emergency event completion rate. The emergency plan simulation result calculation calculates the emergency plan score ratio and the simulation parameter ratio of the plan simulation results according to the evaluation strategy configuration file, and finally generates the joint emergency plan simulation results of each department, and displays and records the results on the training personnel client and the coach client.

[0083] This embodiment focuses on emergency response departments and conducts joint multi-department emergency plan simulations for emergency events. Combining virtual simulation and geographic information technology, it realistically recreates the initiation, development, evolution, and termination of an emergency event. It trains department commanders on how to collaborate with other departments in personnel deployment, material dispatch, and plan deployment. The system also includes emergency event and plan setting procedures, allowing trainers to modify the nature of emergency events based on the circumstances, increasing their diversity and improving training effectiveness. Furthermore, the system incorporates an expert evaluation system, allowing assessment strategies to be set based on the expert system to enhance training priorities.

[0084] Specifically, a specific workflow of this implementation is as follows:

[0085] 1. Each student (trainer) logs into the system and selects a role department, including five roles: on-site disposal department, fire department, emergency department, public security department, and emergency command center.

[0086] 2. The instructor logs in to the instructor system and selects a joint simulation emergency event, such as "Subway Station Arson." The instructor then sets the parameters for the "Subway Station Arson" event, including the risk factor, number of dangerous individuals, evolution events, and emergency event evolution speed. The initial number of passenger casualties is proportional to the risk factor, the number of dangerous individuals is the number of suspects related to the emergency, the evolution events are the evolution of the emergency caused by untimely handling of the current emergency, the evolution speed determines the efficiency of the emergency, and the emergency event evolution threshold. In this case, the instructor sets the evolution event to "Subway Station Explosion," the number of dangerous individuals to 3, the risk factor to high, the emergency event evolution speed to the default parameters, and the road complexity to high.

[0087] 3. The instructor uses the instructor system to configure the emergency response plans available to each joint exercise department, along with the minimum number of labor types and materials required, the types and quantities of labor available to each joint exercise department, and the types and quantities of materials available to each joint exercise department. In this example, the instructor configures all default emergency response plans for each department. The instructor also configures the on-site response department to have five on-site response personnel, two sets of emergency fire extinguishing equipment, one set of emergency communication equipment, and one set of emergency supplies. The fire department is assigned 30 firefighters and five fire trucks. The emergency response department is assigned 15 first responders, three ambulances, and one emergency helicopter. The public security department is assigned 15 traffic police, 20 public security police, 20 armed police, 10 police cars, and 15 police motorcycles. The emergency command center is assigned five on-site management personnel, 30 sets of on-site support materials, 30 sets of life-saving support materials, 10 engineering rescue professionals, 30 sets of engineering rescue materials, and five emergency transport vehicles.

[0088] 4. Each department enters the emergency plan simulation program and initializes the emergency events according to the instructor's settings. In the scenario, a fire occurs at subway station A and three suspects are escaping the scene by disguising themselves as ordinary people. There are five injured people at the scene, two of whom are seriously injured and three are slightly injured. There are 80 people in the subway waiting to be evacuated. Then, a joint emergency simulation of multiple departments begins.

[0089] 5. At time T1, the on-site response department executes the emergency communication equipment [Reporting the Emergency to the Emergency Command Center] plan; instructs two on-site response personnel to use two sets of emergency fire extinguishing equipment for [Initial Fire Control] plan; instructs two on-site response personnel to use the [Passenger Evacuation] plan; and instructs one on-site response personnel to use one set of first aid supplies for [Injured Treatment] plan. Specifically, if the [Reporting the Emergency to the Emergency Command Center] plan is not implemented, other joint exercise departments will not receive emergency information. If the [Initial Fire Control] plan is not implemented within a certain period of time, the fire spread parameter increases, speeding up the emergency event. Implementing the [Passenger Evacuation] plan can accelerate the evacuation speed parameter; implementing the [Injured Treatment] plan can slightly reduce the probability of death of seriously injured personnel parameter. Of these parameters, either the spread parameter increases the risk of injury to stranded personnel; the evacuation speed parameter reduces the number of passengers in the subway station over time, while also accelerating the suspect's escape; and the probability of death of seriously injured personnel parameter can lead to the death of seriously injured personnel over time.

[0090] 6. At T2, the emergency command center received information from the on-site handling department and conducted a joint simulation, and implemented the [Emergency Event Notification] plan to the fire department, emergency department, and public security department; implemented the [Assignment of On-site Management Personnel] plan, assigned 5 on-site management personnel, and mobilized 1 emergency transport vehicle to transport the on-site management personnel to the scene; implemented the [Transportation of On-site Materials] plan, assigned 10 engineering rescue professionals, mobilized 30 sets of on-site guarantee materials, 30 sets of life-saving materials, and 30 sets of engineering rescue and disposal materials to be transported to the scene; implemented the [Subway Suspension] plan to prevent the number of stranded passengers at the current subway station from increasing.

[0091] 7. At T3, the fire department, emergency department, and public security department receive the emergency incident notification from the emergency command center and implement [assign personnel to the emergency command center] to form a joint leadership team to improve the joint response efficiency parameters.

[0092] 8. The public security department will implement the [Traffic Control] plan, dispatching five traffic police officers and five police motorcycles to increase the speed parameters for emergency vehicles near Subway Station A. The public security department will also implement the [Emergency Dispatch] plan, dispatching 20 public security police officers, 20 armed police officers, and 10 police cars to Subway Station A. The fire department will implement the [Emergency Fire Alarm] plan, dispatching 30 firefighters and five fire trucks to Subway Station A. The emergency department will implement the [Ambulance Emergency Rescue] plan, dispatching 15 emergency personnel and three ambulances to Subway Station A.

[0093] At T4, due to the complex road conditions, the Emergency Command Center leadership team instructed the public security department to implement the "Traffic Escort" plan, assigning 10 traffic police officers and 10 police motorcycles to escort fire trucks and emergency vehicles to increase their speed. After the on-site management personnel arrived at the scene, the Emergency Command Center implemented the "On-site Emergency Response" plan, assigning three on-site management personnel to assist with passenger evacuation, one on-site management personnel to establish a security zone outside the subway station, and one on-site management personnel to determine if helicopter access was available nearby. If helicopter access was available nearby, the Emergency Command Center instructed the emergency department to implement the "Helicopter Ambulance Transfer of Seriously Injured Patients" plan. At this moment, the on-site management personnel assisted with passenger evacuation, accelerating the evacuation of the crowd and the suspect's escape. The on-site management personnel also established a security zone outside the subway station to slow the suspect's escape. The helicopter ambulance transfer plan would evacuate all seriously injured patients from the scene.

[0094] At T5, 20 public security officers and 20 armed police officers arrived at the scene. The public security department implemented the [Emergency Evacuation] plan, assigning 10 public security officers to assist in the evacuation of passengers, increasing the speed of evacuation. The public security department implemented the [Suspect Screening] plan, assigning 10 public security officers and 10 armed police officers to conduct suspect screening in the relevant area. The public security department implemented the [Closure Area Blockade] plan, assigning 10 armed police officers to cordon off the relevant area, minimizing the suspect's escape probability and preventing the development of "other violent emergency incidents." Fifteen emergency personnel arrived at the scene. The emergency department implemented the [On-site Emergency] plan, assigning 15 emergency personnel to provide on-site first aid and three ambulances to transport the injured to the emergency center. Simultaneously, the public security department implemented the [Traffic Escort] plan, assigning 10 traffic police officers and 10 police motorcycles to escort the emergency vehicles and increase their speed. 30 firefighters and 5 fire trucks arrived at the scene. The fire department and the emergency command center implemented the [on-site fire disposal] plan, assigning 30 firefighters, 5 fire trucks, 10 engineering rescue professionals, and 30 sets of rescue materials to carry out fire disposal at the subway station.

[0095] At T6, public security police and armed police successfully arrested three suspects, all passengers were evacuated from the subway station, all injured were transferred to the emergency center, and the fire in the subway station was basically extinguished. With the completion of the above, the joint emergency plan simulation was completed, and each process of the simulation was recorded.

[0096] 12. Experts log into the assessment system, set assessment priorities and generate assessment strategy profiles, and score the deduction results in the performance assessment results.

[0097] The parameter calculation in the deduction system is shown in the following formula:

[0098] Risk Factor = 3 (used to evaluate the current risk level of the event, which can be dynamically affected by multiple parameters. Low = 1, Medium = 2, High = 3)

[0099] Number of dangerous elements = 3

[0100] Emergency event evolution speed = 1

[0101] Road complexity = 10 (bottom = 10, middle = 30, high = 50)

[0102] Fire parameter = 0

[0103] Fire spread parameter = 0

[0104] Number of passengers in the station = 80

[0105] Mass evacuation speed = 0

[0106] Suspect's escape speed = 0

[0107] Total number of people at the scene = 80

[0108] Initialization phase:

[0109]

[0110]

[0111] Fire parameter = risk factor × 10 = 30

[0112] Fire spread parameter = risk factor × 0.3 = 0.9

[0113] Mass evacuation speed = (100-fire parameter) ÷ 200 = 0.35

[0114] Suspect's escape speed = crowd evacuation speed × 0.065 = 0.02275

[0115] Real-time calculation stage:

[0116] Probability of death from severe injury = (0.01 × risk factor × duration of injury) %

[0117] Escaped suspect = escape speed × deduction time

[0118] Emergency event evolution progress = emergency event evolution speed × simulation duration + fire intensity parameter. If the emergency event evolution progress > 500, the event will evolve into a "subway station explosion incident":

[0119] Fire intensity parameter = Fire intensity parameter × (1 + Random(0.2,0.5))

[0120] Execute the [Preliminary Fire Control] plan:

[0121] Fire spread parameter = fire spread parameter - 0.1 × number of emergency fire extinguishing devices

[0122] Implementation of the Traffic Control Plan:

[0123] Within 1.5 km of subway station A, the road complexity = 0.

[0124] Implementation of the [Traffic Escort] Plan:

[0125]

[0126] When implementing the [Injured Personnel Treatment] plan, the real-time calculation of the probability of serious injury or death is changed to:

[0127] Probability of death from severe injury = (0.01 × (hazard factor - 0.15 × amount of first aid supplies deployed) × duration of injury) % Execute [Passenger Evacuation], [Emergency Evacuation], and [On-site Emergency Response] plans: Evacuation speed = (100 - fire parameters) ÷ 200 + 0.15 × number of assigned police officers

[0128] +0.1×(number of assigned on-site management personnel + number of assigned on-site disposal personnel)

[0129] Number of passengers in the station = Number of passengers in the station - Evacuation speed × time step

[0130] Execute the [blocking off relevant areas on site], [on-site emergency response], and [blocking off warning areas] plans:

[0131]

[0132] Execute the emergency plan [Transfer of seriously injured patients by helicopter]:

[0133] Number of seriously injured passengers = 0

[0134] If the [Subway Suspension] plan is not implemented, every five minutes:

[0135] Number of passengers in the station = Number of passengers in the station + 30

[0136] Total number of people at the incident scene = Total number of people at the incident scene + 30

[0137] If the [Lockdown of Relevant Areas] plan is not implemented, every 15 seconds:

[0138] Number of passengers in the station = Number of passengers in the station + 1

[0139] Total number of people at the incident scene = Total number of people at the incident scene + 1

[0140] Execute the [On-site Emergency Response] plan:

[0141]

[0142] When the number of seriously injured passengers is less than 0, the number of seriously injured passengers = 0

[0143] Number of passengers with minor injuries = Number of assigned first aid personnel - Number of passengers with minor injuries

[0144] When the number of slightly injured passengers is less than 0, the number of slightly injured passengers = 0

[0145] Execute the [On-site Fire Disposal] plan:

[0146] Fire spread parameter = Fire spread parameter - (number of assigned firefighters × 0.2 + number of assigned fire trucks)

[0147] × On-site firefighting response time

[0148] When the fire spread parameter is less than 0, the fire spread parameter = 0.

[0149] Fire parameters = Fire parameters -

[0150] (Number of assigned firefighters × 2 + Number of assigned fire trucks × 2.5 + Number of engineering rescue professionals × 1.2 + Number of rescue materials × On-site fire response time

[0151] When the fire intensity parameter is less than 0, the fire intensity parameter = 0.

[0152] Execute the [Suspect Screening] Plan:

[0153]
