Description

Technical Field

[0001] This invention belongs to the field of emergency drill evaluation in oil refining and chemical industry, and specifically relates to a method and system for constructing a three-dimensional evaluation model for emergency drills. Background Technology

[0002] Refining and chemical enterprises have inherently high risks in their production and operation activities, and are prone to sudden accidents that can easily escalate and expand. There is an urgent need to improve the emergency response capabilities of key positions and professionals. Emergency drills are the most important means of cultivating initial and professional response capabilities, and are an important tool for testing emergency plans and improving emergency preparedness.

[0003] Emergency drills based on simulated incidents are a new approach and method for emergency drills that has emerged in my country in recent years, and have already been implemented in many refining and chemical enterprises. During these drills, the drill coordinator presents different accident scenarios at various stages to participating organizations and personnel, outlining the drill requirements. Each participant then conducts drills tailored to the specific emergency tasks based on the scenario and their job responsibilities. On-site evaluators assess the drill performance based on the participants' actions in different scenarios, and a post-drill debriefing is conducted to improve emergency response capabilities and enhance emergency preparedness.

[0004] Based on a summary of the current status and implementation cases of scenario-based emergency drills in domestic and international refining and chemical enterprises, the following five problems exist in the assessment of drill levels: 1. The assessment focuses on specific drill tasks, paying less attention to the drill levels of different organizational roles and different drill scenarios; 2. The assessment still relies on the subjective qualitative judgment of the assessors, making the assessment results unquantifiable and lacking scientific rigor; 3. The weights involved in the assessment are mostly manually assigned, making the results susceptible to subjective influence from the assessors; 4. The assessment only targets full-scenario emergency drills, making it difficult to effectively assess the emergency drill levels of single scenarios or multi-scenario joint drills; 5. The same drill personnel undertake different drill tasks in different scenarios, making it difficult to accurately assess the overall drill level of the personnel in multi-scenario drills. Summary of the Invention

[0005] To address the aforementioned issues, this invention proposes a method and system for constructing a three-dimensional evaluation model for emergency drills. The model constructs a three-dimensional evaluation model of emergency drill scenarios, organization, and tasks based on a refining and chemical enterprise scenario. The model construction process utilizes hierarchical analysis and fuzzy evaluation methods to achieve a systematic, scientific, and accurate assessment of the emergency drill level in a refining and chemical enterprise scenario.

[0006] The first objective of this invention is to provide a method for constructing a three-dimensional evaluation model for emergency drills, the method comprising:

[0007] Establish a three-tiered indicator system for emergency drill scenarios, organization, and tasks;

[0008] Based on the analytic hierarchy process, the weight values ​​of each indicator in the three-level indicator system of emergency drill scenario, organization, and task were determined.

[0009] Based on the weight values ​​of each indicator in the three-level indicator system of emergency drill scenarios, organization, and tasks, and the fuzzy comprehensive evaluation method, the evaluation scores of the organizational role in different drills under different drill scenarios and tasks are determined.

[0010] Furthermore, the three-tiered indicator system for determining emergency drill scenarios, organization, and tasks includes:

[0011] The drill scenarios were divided into several scenario indicators according to the stages of the accident evolution.

[0012] Based on the exercise's organizational structure and scenario indicators, the exercise's organizational roles are divided into several organizational indicators;

[0013] The exercise tasks were divided into several task indicators based on organizational and scenario indicators.

[0014] Furthermore, based on the weight values ​​of each indicator in the three-tiered indicator system of emergency drill scenarios, organization, and tasks, and using the fuzzy comprehensive evaluation method, the evaluation scores for the organizational roles in different drill tasks under different drill scenarios are determined, including:

[0015] Based on the three-tiered indicator system of emergency drill scenarios, organization, and tasks, the weights of each indicator in the scenario indicators, organization indicators, and task indicators are defined.

[0016] Based on the analytic hierarchy process and the definition of the weights of each indicator in the scenario, organization, and task indicators, the weight values ​​of each indicator in the three-level indicator system of emergency drill scenarios, organization, and task are calculated.

[0017] Furthermore, based on the analytic hierarchy process (AHP) and the definitions of the weights of each indicator in the scenario, organization, and task indicators, the weight values ​​of each indicator in the three-tiered indicator system of emergency drill scenarios, organization, and tasks are calculated, including:

[0018] Construct a hierarchical analysis indicator system for emergency drills;

[0019] Construct a judgment matrix;

[0020] Based on the definition of the weights of each indicator in the scenario, organization, and task indicators, the emergency drill hierarchical analysis indicator system, and the judgment matrix, the weight values ​​of each indicator in the three-level indicator system of emergency drill scenario, organization, and task are calculated according to the weight calculation method of each indicator layer relative to the previous indicator layer.

[0021] Furthermore, the method for calculating the weights of each indicator layer relative to the previous indicator layer includes the following steps:

[0022] Divide each element in the original judgment matrix by the sum of the columns containing each element in the original judgment matrix to obtain the original judgment matrix for one processing step.

[0023] The judgment matrix obtained from the first processing is added row by row to obtain the judgment matrix for the second processing;

[0024] Divide the elements of the judgment matrix obtained from the secondary processing by the sum of the columns containing each element in the secondary processing matrix to obtain the eigenvector, where each element in the eigenvector represents the weight value of each element in the current level relative to the previous level.

[0025] Furthermore, based on the weight values ​​of each indicator in the three-tiered indicator system of emergency drill scenarios, organization, and tasks, and using the fuzzy comprehensive evaluation method, the evaluation scores for the organizational roles in different drill tasks under different drill scenarios are determined, including:

[0026] Establish a set of comments, which includes graded rating language;

[0027] Fuzzy assignment is performed on the rating language to obtain the assignment matrix;

[0028] Establish a fuzzy relation matrix;

[0029] A fuzzy comprehensive evaluation vector is generated based on the weight values ​​and fuzzy relation matrices of each indicator in the three-level indicator system of emergency drill scenarios, organization, and tasks.

[0030] By multiplying the fuzzy comprehensive evaluation vector and the assignment matrix, the evaluation scores of the exercise organization roles in different exercise scenarios and tasks are obtained.

[0031] Furthermore, the determination of the evaluation score for the organizational role in different drills under different drill scenarios and tasks, based on the weight values ​​of each indicator in the three-tiered indicator system of emergency drill scenarios, organization, and task, and using the fuzzy comprehensive evaluation method, also includes:

[0032] Based on the rating language and assignment matrix used in the exercise, the exercise level score for each exercise task is determined.

[0033] The second objective of this invention is to provide a method for evaluating a three-dimensional emergency drill assessment model, wherein the three-dimensional emergency drill assessment model is constructed using the method described in claim 1 above, and the assessment method includes:

[0034] At the emergency drill site, different rating languages ​​are determined based on the three-dimensional evaluation model of emergency drills and the performance levels of different organizational roles in various drill tasks under different drill scenarios.

[0035] An emergency drill level score is obtained based on different rating languages ​​and assignment matrices.

[0036] The third objective of this invention is to provide a system for constructing a three-dimensional evaluation model for emergency drills, the system comprising: an indicator determination module, a weight calculation module, and an evaluation module;

[0037] The indicator determination module is used to determine the three-tier indicator system of emergency drill scenarios, organization, and tasks;

[0038] The weight calculation module is used to determine the weight values ​​of each indicator in the three-level indicator system of emergency drill scenario, organization, and task based on the analytic hierarchy process.

[0039] The evaluation module is used to determine the evaluation score of the exercise organization role in different exercise scenarios and tasks based on the weight values ​​of each indicator in the three-level indicator system of emergency exercise scenario, organization and task and the fuzzy comprehensive evaluation method.

[0040] A fourth objective of this invention is to provide a computer-readable storage medium storing a computer program that, when executed by a processor, implements the method for constructing a three-dimensional evaluation model for emergency drills as described above.

[0041] The beneficial effects of this invention are:

[0042] This invention proposes a method and system for constructing a three-dimensional evaluation model for emergency drills. It provides a method for dividing indicators into three levels—drill scenario, drill organization roles, and drill tasks—based on the context of refining and chemical enterprises, along with specific examples of the three-level indicator system. Furthermore, combining the analytic hierarchy process (AHP) and fuzzy logic, it presents a method for calculating the weights in the three-level indicator system. Based on this system, the weights of all indicators related to the drill scenarios, organizations, and tasks can be determined, solving the problem that current methods often rely on manual weighting and the evaluation results are easily influenced by evaluators. The invention also quantifies the fuzzy language used in drill evaluation, transforming qualitative assessments of emergency drill levels into quantitative analysis. This provides guidance for improving the systematic, scientific, and accurate assessment of emergency drill levels in refining and chemical enterprises.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] like Figure 1 As shown in the figure, this embodiment of the invention provides a method for constructing a three-dimensional evaluation model for emergency drills, including:

[0057] Step A1: Determine the three-tiered indicator system for emergency drill scenarios, organization, and tasks;

[0058] Step A2: Based on the Analytic Hierarchy Process (AHP), determine the weight values ​​of each indicator in the three-level indicator system of emergency drill scenario, organization, and task;

[0059] Step A3: Based on the weight values ​​of each indicator in the three-level indicator system of emergency drill scenarios, organization, and task, and the fuzzy comprehensive evaluation method, determine the evaluation score of the organizational role in different drills under different drill scenarios and tasks.

[0060] In this embodiment of the invention, the determination of the three-tiered indicator system of emergency drill scenario, organization, and task in step A1 includes:

[0061] The drill scenarios were divided into several scenario indicators according to the stages of the accident evolution.

[0062] Based on the exercise's organizational structure and scenario indicators, the exercise's organizational roles are divided into several organizational indicators;

[0063] The exercise tasks were divided into several task indicators based on organizational and scenario indicators.

[0064] In this embodiment of the invention, the exercise scenario is divided into several scenario indicators according to the accident evolution stage. For example, the exercise scenario is divided into three scenario indicators according to the budding stage, the initial stage, and the development stage of the accident evolution stage.

[0065] In the context of a refining and chemical enterprise:

[0066] For the initial stage, only employees at the job level need to carry out initial emergency response;

[0067] In the initial stage, the entire work team needs to coordinate and work together to carry out emergency response work.

[0068] The development phase involves emergency response at the entire refining and chemical production department level;

[0069] Therefore, based on the scenario of a refining and chemical enterprise and the evolution stages of the initial, initial, and development stages, the exercise scenario is divided into three scenario indicators: job-level accident scenario (initial scenario) S1, team-level accident scenario (initial scenario) S2, and production department-level accident scenario (development scenario) S3. This invention only exemplifies the division of scenario indicators according to the three stages of accident evolution. It can also be divided into several scenario indicators according to the two stages (starting stage and development stage) or four stages (initial stage, development stage, climax stage, and end stage) of accident evolution.

[0070] In this embodiment of the invention, the step of dividing the exercise organization roles into several organizational indicators according to the exercise organization structure and exercise scenario indicators includes:

[0071] Based on the above three scenario indicators and the organizational structure in the refining and chemical enterprise scenario, the organizational roles in the exercise are divided into several organizational indicators.

[0072] First, the roles of the training organizations under different organizational structures in different scenarios are marked as O. nm Where n is the exercise scenario number, and the value of n is one of 1, 2, or 3; m is the exercise organization role number corresponding to the exercise scenario.

[0073] The organizational structure in the refining and chemical enterprise scenario includes job level, team level and production department level. The levels of these three scenario indicators are job level O1, team level O2 and production department level O3.

[0074] Among them, the organizational level O1 at the job level includes the plant area manager O, who is responsible for organizing and directing personnel in different positions within the plant area to carry out emergency response work. 13 Internal operators responsible for operating the emergency response control room at the post level. 11 External operators responsible for on-site emergency response at the job level 12 ;

[0075] The team-level organizational hierarchy O2 includes the team leader (O) who is responsible for organizing and directing the personnel in charge of each unit area and their respective positions to carry out team-level emergency response work. 24 Functional groups assisting work teams in carrying out emergency response work (including process groups responsible for process adjustments) 25 Equipment Group O, responsible for equipment inspection and maintenance 26 Electrical and Instrumentation Group O, responsible for the operation and maintenance of electromechanical instruments. 27 and the Safety and Environmental Protection Group (O) responsible for safety and environmental protection work 28 During the team-level emergency response process, the unit manager O, who was originally responsible for carrying out various post-level emergency response tasks, was... 13 Internal Operations O 11 External Operations 12Their roles and responsibilities will change; the three will serve as key members in team-level emergency response work, namely, the unit manager O... 23 Internal Operations O 21 External Operations 22 ;

[0076] Production department-level organizational hierarchy O3 includes the production department leader (O) who is responsible for organizing and directing all members of the production department to carry out production department-level emergency response work. 39 The fire brigade in the jurisdiction where the auxiliary production department personnel carry out fire rescue work. 310 ,O Functional group assistants who specifically carry out process, equipment, electrical instrumentation, and safety and environmental protection work 35 -O 38 During the production department-level emergency response process, the team leader, who was originally the organizer and commander of the work group-level emergency response, will change roles and become a key member in the production department-level emergency response. 34 The person in charge will lead the unit area manager and staff in carrying out production-level emergency response work. Similarly, the unit area manager, internal operators, and external operators will also change their roles in production-level emergency response, becoming O 33 O 31 O 32 ;

[0077] In this embodiment, for the purpose of facilitating the model construction, the role of the refining and chemical enterprise in the exercise organization is fixed as described above. The composition of the exercise organization at each organizational level can be adjusted (i.e., the role of the exercise organization can be adjusted) according to the actual emergency management work of the refining and chemical enterprise.

[0078] In this embodiment of the invention, the step of dividing the exercise task into several task indicators according to organizational indicators and scenario indicators includes:

[0079] The emergency drill task is marked as T nmi Where n is the number of the corresponding exercise scenario, m is the role number of the exercise organization in the corresponding exercise scenario, and i is the exercise task of the corresponding exercise organization, so that different exercise organization roles in different exercise scenarios can carry out corresponding emergency exercise tasks, thus completing the determination of the three-level indicator system of emergency exercise scenario, organization, and task. For details of the three-level indicator system of emergency exercise scenario, organization, and task, please refer to... Figure 2 In this invention, the scenario content corresponding to the scenario indicators of refining and chemical enterprises, the roles of emergency drill organizers, and the content of emergency drill tasks are detailed in Table 1.

[0085]

[0086] This embodiment merely provides one possible way to determine the three-tiered indicator system of emergency drill scenarios, organization, and tasks. The three-tiered indicator system of emergency drill scenarios, organization, and tasks can be adjusted according to the specific circumstances of the refining and chemical enterprise (the division of accident evolution stages, organizational structure, and actual emergency management work).

[0087] In this embodiment of the invention, the determination of the weight values ​​of each indicator in the three-level indicator system of emergency drill scenario, organization, and task based on the analytic hierarchy process (AHP) in step A2 includes:

[0088] Based on the three-tiered indicator system of emergency drill scenarios, organization, and tasks, the weights of each indicator in the scenario indicators, organization indicators, and task indicators are defined.

[0089] Based on the analytic hierarchy process and the definition of the weights of each indicator in the scenario, organization, and task indicators, the weight values ​​of each indicator in the three-level indicator system of emergency drill scenarios, organization, and task are calculated.

[0090] In this embodiment of the invention, the definition of determining the weight of each indicator in the scenario indicator, organizational indicator, and task indicator based on the three-level indicator system of emergency drill scenario, organization, and task includes:

[0091] based on Figure 2 The exercise scenario, organization, and task-based three-tiered indicator system is shown below, with the weights of each indicator within the scenario, organization, and task categories defined in detail:

[0092] Define the weights of the scenario indicators. The weights of the three scenario indicators—position-level accident scenario S1, team-level accident scenario S2, and production department-level accident scenario S3—are set as q respectively. S1 q S2 q S3 ;

[0093] Define the weights of organizational indicators. For the organizational role in the exercise, the importance and workload of the same personnel in different exercise scenarios vary, and the weights of the same personnel also differ in different scenarios. Specifically, the internal operations team has exercise tasks in scenarios S1, S2, and S3, and these are each assigned a weight of 0. 11 O 21 and O 31 The weights are q O11 q O21 qO31 The external operation involves tasks in scenarios S1, S2, and S3, each set to O. 12 O 22 and O 32 The weights are q O12 q O22 q O32 The device section chief has tasks in scenarios S1, S2, and S3, which are respectively set to O. 13 O 23 and O 33 The weights are q O13 q O23 q O33 The class monitor has tasks in both scenarios S2 and S3, which are set as O respectively. 24 and O 34 The weights are q O24 q O34 The process group has tasks in both scenario S2 and scenario S3, which are set to O respectively. 25 and O 35 The weights are q O25 q O35 The equipment group has tasks in both scenario S2 and scenario S3, which are set to O respectively. 26 and O 36 The weights are q O26 q O36 The electrical instrument group has tasks in both scenario S2 and scenario S3, which are set to O respectively. 27 and O 37 The weights are q O27 q O37 The safety and environmental protection group has tasks in both scenario S2 and scenario S3, which are set to O respectively. 28 and O 38 The weights are q O28 q O38 The production department leader has a task in scenario S3, which is set to O. 39 weight q O39 The local fire brigade has a task in scenario S3, set to O. 310 weight q O310 .

[0094] The weights of task indicators are defined. For emergency drill tasks, the number of tasks for different organizational roles varies in different drill scenarios. To improve the universality of the evaluation model, this embodiment exemplarily fixes the drill tasks for each organizational role in each drill scenario into 5 items, as shown in the following method:

[0095] If the organization has more than 5 training tasks in the actual exercise, the extra 5 training tasks will be included in a task of the same type among the 5 tasks and converted into a new training task for unified analysis.

[0096] If the exercise organization has fewer than 5 exercise tasks, then in the actual evaluation, that task will be set as an empty task, that is, the weight of that task will be 0.

[0097] Among them, the weights of different tasks for indoor operators, outdoor operators, and plant area managers in the job-level accident scenario are q respectively. O11Ti q O12Ti q O13Ti ;

[0098] In a team-level accident scenario, the weights of different tasks for the internal operators, external operators, plant area managers, shift leaders, process group, equipment group, electrical and instrumentation group, and safety and environmental group are respectively q. O21Ti q O22Ti q O23Ti q O24Ti q O25Ti q O26Ti q O27Ti q O28Ti ;

[0099] In a production department-level accident scenario, the weights of different tasks for internal operators, external operators, unit area managers, shift leaders, process groups, equipment groups, electrical and instrumentation groups, safety and environmental groups, production department leaders, and the local fire brigade are as follows: O31Ti q O32Ti q O33Ti q O34Ti q O35Ti q O36Ti q O37Ti q O38Ti q O39Ti q O310Ti .

[0100] In this embodiment of the invention, the definition of the weights of each indicator among the scenario indicators, organizational indicators, and task indicators, and the calculation of the weight values ​​of each indicator in the three-tiered indicator system of emergency drill scenarios, organization, and task, include:

[0101] Construct a hierarchical analysis indicator system for emergency drills;

[0102] Construct a judgment matrix based on the hierarchical analysis index system of emergency drills;

[0103] Based on the definition and judgment matrix of the weights of each indicator in the scenario indicator, organization indicator and task indicator, the weight values ​​of each indicator in the three-level indicator system of emergency drill scenario, organization and task are calculated according to the weight calculation method of each indicator layer relative to the previous indicator layer.

[0104] The specific details of constructing the hierarchical analysis indicator system for emergency drills are as follows:

[0105] A hierarchical analysis index system for emergency drills is constructed, comprising six levels: job level, team level, production department level, joint job level and team level accident scenarios, joint team level and production department level accident scenarios, and full-scenario drill accident scenarios. The index system uses the emergency drill level P as the target level and the drill scenarios S as the target level. n As a Level I indicator, it represents the organizational role of drills under different drill scenarios. nm As a Level II indicator, the exercise tasks T are based on different exercise scenarios and different exercise organization roles. nmi As a Level III indicator layer, the hierarchical analysis indicator system for job-level accident scenario drills is as follows: Figure 3 As shown, the hierarchical analysis index system for team-level accident scenario drills is as follows: Figure 4 As shown, the hierarchical analysis index system for production department-level accident scenario drills is as follows: Figure 5 As shown, the hierarchical analysis indicator system for joint emergency drills at the job level and team level is as follows: Figure 6 As shown, the hierarchical analysis indicator system for joint emergency drills at the team level and production department level is as follows: Figure 7 As shown, the hierarchical analysis indicator system for full-scenario emergency drills is as follows: Figure 8 As shown; where the number of indicators for the exercise scenario, exercise organization roles, and exercise tasks corresponds to the number of scenario indicators, organization indicators, and task indicators in the three-level indicator system of scenario, organization, and task, respectively;

[0106] The above-mentioned hierarchical analysis index system for emergency drills in six different scenarios corresponds to emergency drill level scores for six different drill scenarios, as detailed below:

[0107] The score P for the drill of job-level accident scenario S1 S1 For: P S1 =P O11 ×q O11 +P O12 ·q O12 +P O13 ·q O13 ;

[0108] The score P for the team-level accident scenario S2 drill S2 for:

[0109] P S2 =P O21 ·q O21 +P O22 ·q O22 +P O23 ·q O23 +P O24 ·q O24 +PO25 ·q O25 +P O26 ·q O26 +P O27 ·q O2

[0110] 7+P O28 ·q O28 ;

[0111] Production Department Level S3 Accident Scenario Drill Score P S3 for:

[0112] P S3 =P O31 ×q O31 +P O32 ·q O32 +P O33 ·q O33 +P O34 ·q O34 +P O35 ·q O35 +P O36 ·q O36 +P O37 ·q O3

[0113] 7+P O38 ·q O38 +P O39 ·q O39 +P O310 ·q O310 ;

[0114] The score P for the joint drill of job-level accident scenario S1 and team-level accident scenario S2 S1,S2 For: P S1,S2 =q S1 ·P S1 +q S2 ·P S2 ;

[0115] The score P for the joint drill of team-level accident scenario S2 and production department-level accident scenario S3 S2S3 For: P S2,S3 =q S2 ·P S2 +q S3 ·P S3 ;

[0116] The overall score P of the full-accident scenario drill S1,S2,S3 For: P S1,S2,S3 =q S1 ·P S1 +q S2 ·P S2 +q S3·P S3 ;

[0117] Because the scale of the drill scenarios varies, including joint accident scenarios at the job and team levels, joint accident scenarios at the team and production department levels, and full-scenario emergency drills, the importance of different scenarios varies throughout the drill. This will affect the overall drill score of different organizational roles, essentially "discounting" their overall drill score. The overall drill score for organizational roles is calculated as a weighted average of their drill performance scores in different scenarios, based on the role's performance score in each scenario and the scenario's weight. The calculation method for the overall performance score of different organizational roles in emergency drills is as follows:

[0118] P On =P O11 ·q S1 +P O21 ·q S2 +P O31 ·q S3 , of which O n O 内操 ;

[0119] P Ow =P O12 ·q S1 +P O22 ·q S2 +P O32 ·q S3 , of which O w O 外操 ;

[0120] P Ozz =P O13 ·q S1 +P O23 ·q S2 +P O33 ·q S3 Where Ozz represents O 装置区长 ;

[0121] P Odb =P O24 ·q S2 +P O34 ·q S3 , of which O db O 大班长 ;

[0122] P Og =P O25 ·q S2 +P O35 ·q S3 , of which Og O 工艺组 ;

[0123] P Osb =P O26 ·q S2 +P O36 ·q S3 , of which O sb O 设备组 ;

[0124] P Ody =P O27 ·q S2 +P O37 ·q S3 , of which O dy O 电仪组 ;

[0125] P Oa =P O28 ·q S2 +P O38 ·q S3 , of which O a O 安环组 ;

[0126] P Osc =P O39 ·q S3 , of which O sc O 生产部领导 ;

[0127] P Ox =P O310 ·q S3 , of which O x O 辖区消防队 .

[0128] For emergency drills involving joint exercises of job-level and team-level accident scenarios, and joint exercises of team-level and production department-level accident scenarios, the overall drill level of each participating role is determined based on the weight of the actual participating scenarios and the emergency drill proficiency scores of each organizational role in different scenarios.

[0129] A judgment matrix is ​​constructed based on the hierarchical analysis indicator system of emergency drills, as follows:

[0130] In the actual emergency drill, after discussion by the on-site evaluation team, task T was determined. nmi Compared to organization O nm The relative importance of each pair, organization O nm Compared to scenario S n The relative importance of each pair, the level of emergency drills (P) n Compared to scenario S nThe relative importance of each pair of elements is determined by constructing a judgment matrix T based on the 1-9 scale method. nmi -O nm Judgment matrix O nm -S n Judgment matrix P n -S n Among them, for the exercise level-exercise scenario judgment matrix P n -S n If it is a single-scenario drill (one of the six drill scenarios established in the previous step: job-level accident scenario drill, team-level accident scenario drill, and production department-level accident scenario drill), then there is no need to construct a judgment matrix; the score of the corresponding scenario drill is the overall level of the emergency drill. The judgment matrix T... nmi -O nm As shown in Table 2, the judgment matrix O nm -S n As shown in Table 3, the judgment matrix P n -S n As shown in Table 4;

[0137] Based on the definition and judgment matrix of the weights of each indicator in the scenario, organization, and task indicators, and according to the weight calculation method of each indicator layer relative to the previous indicator layer, the weight values ​​of each indicator in the three-level indicator system of emergency drill scenario, organization, and task are calculated as follows:

[0138] The method for calculating the weight of each indicator layer relative to the previous indicator layer includes the following steps:

[0139] The process of dividing the elements of the original judgment matrix by the sum of the columns containing each element yields the original judgment matrix for the first processing step, i.e., normalizing the judgment matrix column by column. The normalized judgment matrix (i.e., the judgment matrix for the first processing step) is calculated according to equation (1):

[0165] Based on the weight calculation method of each indicator layer relative to the previous indicator layer and the emergency drill hierarchical analysis indicator system constructed in the previous step, the weight values ​​corresponding to each exercise task of each exercise organization role under different exercise scenarios are obtained. Among them, the weight of each element of the determined task indicator layer relative to the organization indicator layer is the weight of each exercise task; the weight of each element of the determined organization indicator layer relative to the scenario indicator layer is the weight of each exercise organization role; and the weight of each element of the determined scenario indicator layer relative to the exercise level layer is the weight of each exercise scenario. The weight of each element is filled into the corresponding position in the accident scenario evaluation table at the post level, team level, and production department level. The accident scenario evaluation table at the post level is shown in Table 8, the accident scenario evaluation table at the team level is shown in Table 9, and the accident scenario evaluation table at the production department level is shown in Table 10.

[0176] Step A3 describes determining the evaluation score for the organizational role in different drill scenarios and tasks based on the weight values ​​of each indicator in the three-tiered indicator system of emergency drill scenarios, organization, and task, and using the fuzzy comprehensive evaluation method. This includes:

[0177] Establish a set of comments, which includes graded rating language;

[0178] Fuzzy assignment is performed on the rating language to obtain the assignment matrix;

[0179] Establish a fuzzy relation matrix;

[0180] A fuzzy comprehensive evaluation vector is generated based on the weight values ​​and fuzzy relation matrices of each indicator in the three-level indicator system of emergency drill scenarios, organization, and tasks.

[0181] By multiplying the fuzzy comprehensive evaluation vector and the assignment matrix, the evaluation scores of the exercise organization roles in different exercise scenarios and tasks are obtained.

[0182] The establishment of the comment set, which includes graded rating language, is as follows:

[0183] In this embodiment, for example, a set of comments V is established for the degree language of each emergency drill task assessment, namely "good, relatively good, average, relatively poor, and poor", that is: V = {good, relatively good, average, relatively poor, poor}. The degree language of other assessments in the comment set is defined. For example, a set of comments V = {good, average, and poor} is established for the degree language "good, average, and poor" corresponding to three degree languages.

[0184] The process of performing fuzzy assignment on the rating language to obtain the assignment matrix is ​​as follows:

[0185] The five levels in the aforementioned evaluation set were fuzzified and assigned values: "Good" was 100 > V ≥ 80, "Fairly Good" was 80 > V ≥ 60, "Average" was 60 > V ≥ 40, "Poor" was 40 > V ≥ 20, and "Very Poor" was V < 20 (see Table 11). A weighted average method was used to determine the final quantitative evaluation result, taking the median value of each of the five fuzzification intervals: "Good" = 90, "Fairly Good" = 70, "Average" = 50, "Poor" = 30, and "Very Poor" = 10, forming the assignment matrix P = [90, 70, 50, 30, 10]. T This embodiment only provides an example of fuzzy assignment, and the specific data assigned can be adjusted according to the actual emergency drill requirements.

[0186] Table 11

[0187]

[0188] The establishment of the fuzzy relation matrix is ​​as follows:

[0189] Based on the established set of comments and the evaluation results for each emergency drill task, the T value for each drill task is calculated individually. nmi Relative to the membership degree of the evaluation set, there are n on-site evaluators for exercise task T. nmi In the evaluation, if q experts select a certain rating from the rating set, then the membership degree of that indicator to that rating is q / n. Based on this, a fuzzy relation matrix G = (g uv ) l×k , where g uv This represents the membership degree of the u-th indicator to the comment.

[0190] The fuzzy comprehensive evaluation vector is generated based on the weight values ​​and fuzzy relation matrices of each indicator in the three-level indicator system of emergency drill scenarios, organization, and tasks, as detailed below:

[0191] Based on the weight vector Q of each exercise task indicator determined by the emergency exercise indicator weight calculation model constructed according to the analytic hierarchy process (AHP) scenario of refining and chemical enterprises, Q and the fuzzy relation matrix G are synthesized using fuzzy operators to obtain the fuzzy comprehensive evaluation vector Y for each emergency exercise task in the exercise organization roles. The fuzzy operator used is a weighted average operator.

[0192] By multiplying the fuzzy comprehensive evaluation vector and the assignment matrix, the evaluation scores of the exercise organization roles in different exercise scenarios and tasks are obtained, as follows:

[0193] Multiplying the determined fuzzy comprehensive evaluation vector by the assignment matrix determines the exercise organization role O corresponding to each exercise task.nm Evaluation score Complete the construction of a three-dimensional evaluation model for emergency drills.

[0194] Specifically, the scores for each emergency drill task are determined by averaging the scores from different on-site evaluators, based on the rating language and assignment matrix provided by the on-site evaluators. Here, an embodiment of the present invention exemplarily provides a position-level accident scenario for the operator O. 12 The exercise level assessment form (on-site assessor 1) is shown in Table 12. Specifically, based on the set of comments from the on-site assessors and combined with the assignment matrix, the exercise task assessment score is obtained. Then, the corresponding exercise task assessment scores obtained from the set of comments from multiple on-site assessors are summed and averaged to obtain the exercise score for each exercise task.
