Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of urban safety management, and relates to a data-driven urban safety management performance dynamic evaluation method and device. BACKGROUND

[0002] Performance evaluation, as a technical support and management tool for urban governance, has an inherent connection with promoting urban development, and has important practical significance. For example, the existing patent CN119494463A discloses a "city operation index monitoring method based on multi-source heterogeneity", which integrates data resources in the fields of industrial economy, urban governance, green ecology, and happiness and livability in the process of city operation, and provides data decision support for city operation comprehensive situation awareness, risk identification and development trend through data aggregation, data mapping, data governance, model analysis and other operations. In addition, the existing patent CN120069678A discloses a "carbon performance evaluation method based on a data envelope comprehensive model", which mainly aims at the field of carbon performance evaluation, and through the steps of obtaining data, analyzing the evaluation system, outputting results, analyzing the output system results by using the data envelope comprehensive model to obtain comprehensive evaluation parameters, and using the parameters to divide the performance level to obtain the performance evaluation results, the carbon performance evaluation of the envelope comprehensive model is completed.

[0003] However, in the existing disclosed patent research, there is no dynamic evaluation technology for the performance of urban safety management. The existing performance evaluation is mainly applied to meteorological, housing and other industry departments and related enterprise personnel management work. The description of data sources, urban safety indicators, dynamic evaluation and continuous improvement in the technology and method of urban safety management lacks accuracy and integrity, and an evaluation model integrating "results, processes and keys" has not been established. Due to the lack of process evaluation technology, combined with the fact that multi-level and multi-subject data cannot be shared, it is difficult to find potential problems in data processing, supervision and execution in urban safety management work, and it is difficult to realize the continuous optimization and adaptive adjustment of urban safety governance. At the same time, a complete PDCA closed-loop technical chain has not been formed, and a dynamic evaluation model based on historical data and real-time monitoring data is lacking, so it is difficult to realize dynamic tracking and continuous optimization of rectification effect.

[0059] In some embodiments, the multi-level urban safety field data refers to a full set of data covering all dimensions and levels of urban safety management collected based on a "point-line-surface-body progressive support framework", and the "multi-level" reflects the progressive relationship of data in space, content and granularity.

[0060] Step S130, constructing a three-dimensional index of urban safety management performance evaluation according to the urban safety material data set; the three-dimensional index includes process performance indicators, result performance indicators and key performance indicators.

[0061] In some embodiments, the process performance indicators are used to evaluate the execution process specification of urban safety management, such as hazard detection coverage, rectification closed-loop rate, emergency drill frequency, safety training duration, etc.

[0062] The result performance indicators are used to evaluate the direct output effect of urban safety management, such as the number of annual safety accidents, the number of deaths, the amount of economic loss, the number of major risk point control, etc.

[0070] In step S170, the urban safety management performance of the city to be evaluated is dynamically evaluated according to the urban safety management performance evaluation model, and an evaluation result is obtained.

[0071] The data-driven urban safety management performance dynamic evaluation method, device and equipment provided by the embodiments of the present application effectively break through the data barriers of multiple departments and multiple levels by means of the four-level data collection channels and coding rules of "point-line-surface-body", realize the standardized processing and intercommunication sharing of multi-source heterogeneous data, solve the problems of incomplete data sources and difficult integration in the prior art, provide accurate and comprehensive data support for urban safety management performance evaluation, and improve the usability and value of data.

[0072] In terms of evaluation system, the three-dimensional performance evaluation system of "process, result and key" is constructed, which fills the gap of the lack of process evaluation in the prior art. By clearly defining the specific indexes and quantitative scoring methods of each dimension, the performance evaluation is changed from a single result-oriented to a comprehensive consideration of the entire management process, which can more accurately find potential problems in data processing, supervision and execution, and improve the scientificity and objectivity of the evaluation.

[0073] In terms of management closed loop, the application of innovative PDCAA dynamic mechanism and information platform forms a complete management closed loop of "discovery, assignment, rectification, acceptance and cancellation", realizes dynamic tracking and continuous optimization of rectification effectiveness. At the same time, the block chain storage technology ensures the non-tamperability of key information, ensures the transparency and traceability of the management process, solves the problems of lack of complete PDCA closed loop technical chain and lack of traceability in rectification in the prior art, and improves the execution and public credibility of urban safety management.

[0076] In some embodiments, the above step S140 can be implemented by the following steps S141-S143:

[0077] Step S141, according to the preset scoring rule, the first indicator score of each process performance indicator is calculated; the calculation formula of the first indicator score is: ; In the formula, i is the i-th process performance indicator; n is the total number of process performance indicators; is the i-th process performance indicator evaluation score.

[0082] Step S152, according to the comprehensive score and the preset performance evaluation grade division rule, the performance of urban safety management of each level unit is graded to obtain the performance evaluation grade result of urban safety management.

[0083] In some embodiments, the method can further include the following:

[0084] Establish a hierarchical feedback improvement process, evaluate and feedback each task online through the city safety comprehensive management system, and set a time limit for rectification strategy;

[0085] Establish a hidden danger rectification full life cycle management account, and automatically record the hidden danger discovery time, rectification requirement, rectification person in charge, rectification progress and acceptance result, form a closed loop record of “discovery, assignment, rectification, acceptance, cancellation”, and support multi-dimensional query of historical rectification data; Relying on the information platform to realize the whole process digital management and control of “task assignment, data collection, audit scoring, feedback improvement”;

[0089] The dynamic performance evaluation technology based on PDCAA of the application: In view of the problem that the traditional evaluation lacks process quantification, the Assess evaluation link is added in the traditional PDCA, a five-stage management closed loop of “planning, execution, checking, evaluation and improvement” is constructed, a three-dimensional performance evaluation model construction technology is formed by combining “process index, result index and key effect index”, and the core pain point of process control loss is solved, which is the basic innovation of the patent.

[0090] The multi-source heterogeneous data double-track weighting intelligent evaluation technology of the application: a double-track weighting algorithm of “structural entropy weight + expert correction” is proposed, which combines the structural entropy weight method (information entropy quantization index dispersion) and the Delphi method (expert experience correction weight deviation) to construct a dynamic weight distribution model. Through the five-level data governance architecture (collection layer→cleaning layer→fusion layer→application layer→display layer), the structured and unstructured data of emergency, city management, housing construction, fire fighting and other city industry departments are integrated, and the intelligent evaluation of “data driven + benchmarking analysis” is realized by combining the matter element extension model.

[0092] In the following, an exemplary application of the application embodiment in an actual application scenario will be described.

[0093] The application is based on new features of urban safety management in a big data environment, aims to provide a data-driven dynamic evaluation method of urban safety management performance, solves the problems of great difficulty in multi-source heterogeneous data integration, lag in data real-time and dynamic updating, quantitative loss in the urban safety management performance evaluation process, and solidification of the urban safety management performance evaluation work cycle, and simultaneously develops and applies a supporting information platform according to the method, regularly carries out performance evaluation and online improvement feedback work, and provides real-time and accurate decision-making basis for urban safety management.

[0094] The specific steps are as follows:

[0095] 1) Multi-source heterogeneous data sources and structured presentation:

[0096] Step 1: Clearly define the "point-line-surface-body" four-level urban safety data collection channels from bottom to top.

[0097] Take social units and grassroots communities as the smallest data collection units, collect original data through grid management terminals and sensor networks, including work plans, hidden danger self-checking tables, equipment operation parameters, hidden danger rectification records, etc. The industry supervisory department deploys data access environment, interfaces point-level data and industry-specific information systems, realizes heterogeneous data normalization processing according to index task setting requirements, forms industry data sets and synchronizes to the surface level. Districts (development zones) establish data hubs, integrate line data of various industries, generate regional safety situation data sets, and push to the body level after auditing. The city-level platform aggregates the data of the surface level of each district and the line data of each industry department, constructs a distributed database, and meets the needs of global risk judgment and performance evaluation.

[0098] Step 2: Encode the work subject and data files.

[0099] According to the coding principle of "① work department (county) code-② work type code-③ target task serial number-④ work link code-⑤ data attribute code-⑥ evaluation content code-⑦ file serial number", the data subjects in the field of urban safety are coded and classified to form the urban safety data set.

[0100] ①Working department (county) code: English abbreviation of government industry department;

[0101] ②Working type code: common indicators 0, source governance I, safety risk monitoring and early warning II, major hidden danger investigation and rectification III, safety supervision and management IV, safety guarantee capacity V, safety status VI, encouragement item VII;

[0102] ③Target task number: 4 common indicators + 101 tasks + encouragement items;

[0103] ④Work link code: P planning, D implementation, C supervision and inspection, A improvement;

[0104] ⑤Data attribute code: policy document ZC, process data GC, account statement TB, facility construction SJ;

[0105] ⑥Evaluation content code: number of evaluation content corresponding to target task;

[0106] ⑦File number: number of collected files 1, 2, 3… etc.

[0107] 2) Scientifically set evaluation indicators:

[0108] First step: Clearly define the three-dimensional indicators of urban safety management performance evaluation, such as Figure 2 .

[0109] ①Process indicators: Process performance indicators are mainly used to measure the process performance of urban safety management work. Mainly including X1 clear object and scope, X2 clear work content, X3 clear responsibility department (person in charge) and division of work, XP planning, XD implementation, XC supervision and inspection, XA improvement, X4 standardization of archives.

[0110] ②Result indicators: Used to measure the file results of work, including policy documents, process data, account statements, facility construction data, which need to meet the requirements of evaluation rules on the integrity and standardization of results. Mainly including: Y1 policy document, Y2 process data, Y3 account statement, Y4 facility construction.

[0111] ③Key performance indicators: Mainly used to measure the key performance of urban safety management work, which is the key performance indicators required by the national evaluation standard for urban safety management work.

[0112] 3) Construction and implementation of "process, result, improvement" three-dimensional performance evaluation system:

[0113] The first step is to measure the performance of urban safety management, including the definition of objects and scope X1, the definition of work content X2, the definition of responsible departments (person in charge) and division of work X3, planning XP, supervision and inspection XC, improvement XA, and the standardization degree of archives X4.

[0114] Each process performance indicator in the urban safety management performance evaluation score sheet is scored 10 points, and the scoring standard is divided into three levels: no: 0-3 points; have, but not perfect: 4-7 points; perfect work: 8-10 points. The total score of each work task process performance indicator is the sum of all process performance indicators. Then the total score of the process performance indicators is converted into percentage, which is the process performance indicator score A of the city-level departments and county (development zone) urban safety management. The specific conversion process is shown in formula (1):

[0115] (1);

[0116] In the formula, i is the i-th process performance indicator; n is the total number of process performance indicators; is the i-th process performance indicator evaluation score.

[0117] The second step is to measure the performance of the file results formed in the process of urban safety management, including policy documents Y1, process data Y2, account statements Y3, and facility construction Y4.

[0118] Policy documents Y1 mainly include laws, regulations, rules, regulations, standards, schemes, and individual work deployment notices; process data Y2 includes implementation plans, planning, work reports, records, account statements, inspection records, and improvement measures generated in the planning and implementation stages; account statements Y3 include records, summaries, and statistical analysis reports; and facility construction Y4 includes achievement file verification data generated in the process of infrastructure construction to ensure the normal operation of urban main facilities and maintain urban safety management capabilities.

[0119] Because the city-level departments and counties (development zones) have different tasks in urban safety management, there are differences in the target scores of the achievement performance indicators. In order to compare the completion of the achievement performance indicators of the city-level departments and counties (development zones), the index completion rate is used as the achievement performance indicator score for comparative analysis. The calculation formula of the achievement performance indicator completion rate B is shown in formula (2):

[0120] (2);

[0121] In the formula, c is the actual score of the outcome performance indicator; d is the expected score of the outcome performance indicator.

[0122] Third step: Measure the key results achieved by the city safety management work, and the key result indicator compliance rate E is calculated according to formula (3):

[0123] (3);

[0124] In the formula, a is the number of completed key performance indicators; b is the total number of key performance indicators.

[0125] Fourth step: Calculate the comprehensive score, and the comprehensive score F of each department at the municipal level and county (development zone) is calculated according to formula (4): ; In the formula, is the preset process performance indicator weight; is the preset result performance indicator weight.

[0128]

[0129] 4) Build a continuously updated city safety management performance evaluation model:

[0130] First step: Improve the PDCA cycle to PDCAA dynamic mechanism.

[0131] On the basis of the traditional "plan, execute, check, improve", add the performance evaluation link of Assess, form the "Plan, Do, Check, Assess, Action" management closed loop, quantify the process management effect through performance evaluation, and refine the quantifiable evaluation indicators, and comprehensively test and evaluate from the three dimensions of "process performance, outcome performance and key indicators".

Relying on the information platform, realize the whole process digital management and control of "task assignment, data collection, audit scoring, feedback and improvement".

[0138] Third step: Build a dynamic index optimization mechanism. According to the new technology application and new risk, adjust 5%-10% of the evaluation indexes every year, invite experts to dynamically calibrate the index weight, and ensure the timeliness of the evaluation system.

[0139] Fourth step: Implement periodic review and capacity evolution. Relying on the digital twin base of the achievement performance visualization module, simulate extreme scenarios, and generate at least 10 targeted and scientific improvement suggestion analysis reports, which provide basis and guidance for urban safety management.

[0140] Fifth step: Record the task disposal process, feedback opinion, acceptance result and chain storage, ensure that the data cannot be tampered with, and automatically generate a closed loop report containing the disposal process, participants, time nodes after disposal is completed.
