1 is a flow chart showing an analysis method of production environment security according to an embodiment of the present invention. As shown in FIG. 1, the production environment security analysis method 100 in this embodiment includes the following steps:

Step S110, acquiring multiple levels of the indicator system that affect the safety of the production environment and safety production indicators of each level, the plurality of levels including at least the lowest level, at least one intermediate level, and the highest level;

Step S120: Calculating weight values of the safety production indicators of the lowest level and the intermediate level by using an analytic hierarchy process;

Step S140, performing normalization processing on each historical data of the same safety production indicator for the predetermined period of the plurality of analysis objects for each historical data of the acquired same safety production indicator;

Step S150, calculating the highest level according to the historical data of the lowest level safety production index after the standardization process, the weight value of the lowest level safety production index, and the weight value of the intermediate level safety production index. Safety production index.

In the embodiment of the present invention, the establishment of an indication system (IS) is a premise and basis for analyzing a research object, and the indicator system can decompose the abstract research object into a concrete and operable structure, and establish The index system of the safe production environment analyzes the safety production index, and can analyze the safety of the production environment as a whole and predict the safety production accidents.

In the process of analyzing the safety production index, the contribution of each indicator in the overall assessment and analysis is often different, and the safety analysis of the production environment involves many indicators, the data statistics are large, and the relationship between the indicators is complex. Therefore, the weight of each indicator cannot be simply determined from the perspective of data information. In order to make the process of evaluation and analysis clearer and clearer, in the embodiment of the present invention, the index system of the evaluation or analysis program is determined, and the index system is constructed. Hierarchical structure, and Analytic Hierarchy Process (AHP) is used as a method to determine the weight of each safety production indicator at a specified level.

In step S110, the indicator system of the safe production environment may have three or more levels.

Specifically, if there are three levels, the three levels are respectively the lowest level, the middle level, and the highest level; if there are three or more levels, the three or more levels are respectively the lowest level and more than one intermediate level. And the highest level.

As an alternative embodiment, FIG. 2 is a detailed flow chart showing the calculation of the weight values of the respective safety production indicators of the lowest level and the intermediate level in FIG. As shown in FIG. 2, step S120 may specifically include the following steps:

In step S121, the importance scores of the safety production indicators of the lowest level and the middle level are respectively obtained.

In the above step S121, the importance score is obtained by scoring the importance of each safety production index at the lowest level and the middle level according to a preset index importance level score standard.

Step S122, based on the importance scores of the safety production indicators of the lowest level and the intermediate level, respectively construct the index weight judgment matrix of the lowest level and the middle level.

In step S123, the weight values of the safety production indicators in the index weight judgment matrix of the lowest level and the middle level are respectively calculated.

Through the above steps S121-S123, the safety production indicators of each level are scored, a judgment matrix is constructed, and the weight values of the respective safety production indicators in the constructed judgment matrix are obtained by calculation.

An important feature of the analytic hierarchy process is the use of the ratio of the degree of importance between each safety production indicator and the other safety production indicators at the same level to indicate the importance level, ie the weight of the safety production indicator. In the usual practice, specific users can use the analysis scale of the analytic hierarchy process to compare the safety production indicators of each level by pairwise comparison and score according to their importance.

For ease of understanding, Table 1 below exemplarily shows the pairwise comparison scores of the analytical criteria of the conventional AHP and their meanings.

Table 1 Traditional Analytical Method Analysis Standards

According to the analysis criteria in Table 1 above, the matrix formed by the comparison between the respective safety production indicators at the specified level and other safety production indicators is the judgment matrix.

In the embodiment of the present invention, if each safety production index in a large number of safety production indicators is compared with other safety production indicators, since the number of safety production indicators is large, the comparison process continues until the later stage of the comparison process, and a tedious comparison is made. It will have a greater impact on the correct judgment of the person, thus affecting the scientific and consistency of the score results.

In the embodiment of the present invention, in order to simplify the analysis method of the importance of the safety production index, improve the scientificity and consistency of the score result, the construction method of the index weight judgment matrix is improved.

Specifically, in step S121, importance is directly scored for each safety production indicator of the specified level according to a preset index importance level scoring standard.

For ease of understanding, Table 2 below exemplarily shows the importance degree definition and corresponding score for each safety production index in the scoring standard of the analytic hierarchy process according to an embodiment of the present invention. The examples in Table 2 should not be construed as specific definitions of the AHP scoring criteria.

Table 2 Analytic Hierarchy

Definition of importance	score
unimportant	1
Slightly important	3
Quite important	5
Obviously important	7
Absolutely important	9
Between two adjacent levels	2, 4, 6, 8

According to the example in Table 2 above, the importance degree of each safety production index in the specified level is scored according to the preset index importance degree scoring standard, and the index weight of the level is determined according to the importance score of each safety production index. matrix.

As an optional embodiment, the step S122 may specifically include: calculating an average score of the importance scores of the safety production indicators of the lowest level and the intermediate level by using the importance score; and calculating an average score of the importance scores according to the calculation, The index weight judgment matrix of the lowest level and the middle level is respectively constructed, wherein the value of the matrix element in the index weight judgment matrix is the average score of the importance score of the safety production indicator corresponding to the column of the matrix element and the row corresponding to the row of the matrix element The average score of the average score of the importance score of the safety production indicator.

For ease of understanding, the construction process of the index weight judgment matrix is described below by a specific example. In this example, the consequences of the accident as a tiered indicator include the following indicators such as: D1, the number of deaths from production safety accidents; D2, the number of deaths from fire accidents; D3, the number of road traffic deaths.

First, a specific user, such as an expert or other designated assessor, scores the importance of the indicators D1, D2, and D3 according to the analytic hierarchy scoring criteria shown in Table 2 according to professional knowledge. As an example, Table 3 below schematically shows the results of three specific users scoring the importance of the level indicators.

Table 3 level indicator importance score

Specific user	Indicator number	Importance rating
Specific user 1	D1	7
Specific user 1	D2	7
Specific user 1	D3	0
Specific user 2	D1	5
Specific user 2	D2	5
Specific user 2	D3	5
Specific user 3	D1	0
Specific user 3	D2	9
Specific user 3	D3	9

As shown in Table 3, the scores of the importance scores of the indicators D1 are 7, 5, and 0; the scores of the importance scores of the indicators D2 are 7, 5, and 9, respectively; and the scores of the importance scores of the indicators D3. They are 0, 5, and 9, respectively.

Secondly, the average score of the importance scores of each indicator is calculated by the ratio of the sum of the importance scores of the various indicators to the number of specific users participating in the score.

Specifically, the average score of the importance score of the index D1 is 4; the average score of the importance score of the index D2 is 7; and the average score of the importance score of the index D3 is 4.667.

Next, based on the calculated average scores of the importance scores of the respective indicators, the index weight judgment matrices of the lowest level and the intermediate level are respectively constructed.

Table 4 below schematically shows the index weight judgment matrix constructed based on the average score of each indicator importance score, using the ratio of the pairwise comparison between the indicators.

Table 4: Location point value of the indicator weight judgment matrix

	D1	D2	D3
D1	1	1.75	1.16675
D2	0.57143	1	0.66671
D3	0.85708	1.49989	1

In Table 4 above, a combination of pairwise comparisons of the average values of the importance scores of the indicators D1, D2, and D3 can form 3 × 3 position points:

(D1, D1), (D1, D2), (D1, D3),

(D2, D1), (D2, D2), (D2, D3),

(D3, D1), (D3, D2), (D3, D3).

The value of each position point in the index weight judgment matrix is the ratio of the average score of the importance score of one indicator after the position point to the average score of the importance score of the previous indicator.

That is to say, the value of the matrix element in the index weight judgment matrix is the ratio of the average score of the importance score of the index corresponding to the column of the matrix element to the average score of the importance score of the index corresponding to the row of the matrix element.

The indicator weight judgment matrix is the embodiment of the degree of association between the indicators, and the degree of relevance is determined by the rating of all indicators by all specific users.

In the embodiment of the present invention, the weight value of each safety production indicator of the level can be calculated by constructing the index weight judgment matrix of the specified level.

The following continues to refer to the indicator weight judgment matrix in Table 4 above, and details how to calculate the weight value of each indicator in the weight judgment matrix.

Table 5 below schematically shows the summation of each row of the matrix according to the index weight judgment matrix in Table 4, and the summation result of summing all the values.

Table 5: Index weighting judgment matrix summation of rows and summation of all values

As shown in Table 5, first, the value of each position point of the index weight judgment matrix is summed for each line, and the summation result of each position point of the first line is 4.4175, and the sum result of each position point of the second line is obtained. It is 2.23814, and the summation result of each position point in the third line is 3.35697.

Secondly, the summation results of each row position point are further summed to obtain the sum of the values of all the position points in the index weight judgment matrix, that is, 10.01261.

Then, the weight value of the index D1 is represented as ω ₁ , the weight value of the index D2 is represented as ω ₂ , and the weight value of the index D3 is represented as ω ₃ . Then the value of ω ₁ is the ratio of the summation result of each position point of the first line to the summation result of all the position points, that is,

The same calculation

In some embodiments, for the calculated weight value, a rounding operation may be further performed to quantize the weight value to the last two digits of the decimal point. That is, the weight values corresponding to the D1, D2, and D3 indicators in the index weight judgment matrix are ω ₁ = 0.44, ω ₂ = 0.22, and ω ₃ = 0.34, respectively.

In practical applications, there are many methods for calculating the weight values of the indicators by the index weight judgment matrix, which is not mentioned here.

It should be understood that the method for calculating the weight value of the index according to the constructed index weight judgment matrix in the embodiment of the present invention should not be construed as limiting the weight value calculation method in the embodiment of the present invention. That is to say, in the embodiment of the present invention, the method for calculating the weight value of each safety production index according to the constructed index weight judgment matrix can be selected according to the actual calculation requirement.

In some embodiments, since the safety analysis of the production environment involves a large number of safety production indicators and is susceptible to other human factors, the constructed indicator weight judgment matrix may have a consistency problem, in order to improve the indicator. The accuracy of the data in the weight judgment matrix, as an optional embodiment, the step S123 may further include the following steps: performing consistency check on the index weight judgment matrix of the lowest level and the intermediate level respectively to determine the index weights of the lowest level and the middle level It is judged whether the matrix has consistency; and if the index weight judgment matrix of the lowest level and the intermediate level has consistency, the weight values of the respective indicators of the lowest level and the intermediate level are calculated.

In the embodiment of the present invention, the consistency check is performed on the index weight judgment matrix, and the test result weight judgment matrix is determined by the test result to improve the correctness and validity of the overall analysis and analysis result.

If the constructed index weight judgment matrix can pass the consistency test, the importance of each safety production indicator of the level needs to be re-scored and the index weight judgment matrix is constructed.

As an optional embodiment, in step S130, when it is necessary to perform evaluation analysis on a plurality of analysis objects, historical data of the lowest level safety production indicators of different time periods of the predetermined period are respectively acquired for each analysis object, for example, obtaining The historical data of the lowest level of safety production indicators of the A object, the B object, and the C object in the past five years. Since safety production indicators include positive safety production indicators that have a positive impact on the safety of the production environment and negative safety production indicators that have a negative impact on the safety of the production environment, historical data for the lowest level of safety production indicators includes positive Historical data on safety production indicators and historical data on negative safety production indicators.

In the safety analysis of the production environment, it is sometimes necessary to compare not only the safety production indexes of multiple analysis objects at the same time period, but also the safety production indexes of multiple analysis objects at different time periods. In the past, due to the inconsistent standards in the analysis process, it is difficult to compare the safety production indexes in different time periods, even if the comparison is very inaccurate.

Therefore, in step S140, each history data of the acquired same safety production index is subjected to standardization processing based on all history data of the same safety production index for a predetermined period of the plurality of analysis objects.

Specifically, in step S140, step S141 is included, and each historical data of the acquired same safety production indicator is normalized based on all historical data of the same safety production indicator.

Alternatively, a normalization method represented by the formula (2) may be employed, and the formula (1) represents a calculation method of the coefficient of variation, wherein x represents historical data of the safety production index, and max(x) represents the plurality of analyses. The maximum value of the historical data of the same safety production index for the predetermined period of the object, cv represents the coefficient of variation, σ represents the standard deviation of the historical data of the same safety production index for the predetermined period of the plurality of analysis objects, and μ represents the plurality of The average value of the historical data of the same safety production index for the predetermined period of the analysis object, and z represents the historical data of the safety production index after the normalization process, wherein

The historical data normalization process for the forward safety production index can be normalized only, and the normalization process for the historical data of the negative safety production index includes not only the normalization process but also the forward processing. That is, step S140 is further included in step S140, and the normalization processing shown in the equation (3) is performed after the normalization processing is performed on the history data of the negative safety production index, and z' indicates that the forwardization is performed. Historical data of the negative safety production indicators after processing.

By adopting the above-mentioned standardization processing, the influence of the data difference of the collected historical data due to different dimensions and different data sizes on the data analysis is eliminated, the data precision is improved, and the collected historical data is standardized. In addition, the historical data of the same safety production index is normalized by using the same standard method as described above. In addition, by adopting the above-described standardization method, all the historical data of all the analysis targets of the safety production index are considered, and the data of the safety production index is unified into the range of (0, 1). In addition, by adopting the above-mentioned standardization method, it is also considered to consider the degree of dispersion of a group of data composed of the same safety production index, that is, the historical data of the same safety production index of a plurality of analysis objects, to avoid the same increase or decrease. A contradiction that leads to the same normalization result.

Next, in step S150, according to the historical data of the lowest level safety production index after the normalization processing, the weight value of the lowest level safety production index, and the weight value of the intermediate level safety production index The highest level of safety production index.

For the sake of easy understanding, taking the safety production index of the third level as an example, the calculation of the highest level of indicator data can be performed by the following formula (4).

In the above formula (4), SPI represents the safety production index, that is, the highest level index, Inc. represents the safety production accident index, IR represents the inherent risk index, SafetySup represents the safety supervision index, and Inc, IR and SafetySup represent the intermediate level, ie, the second level. index.

And, where α _j is the weight of the secondary indicator, that is, the safety production accident index, β _j is the weight of the secondary indicator, the inherent risk index, γ _j is the weight of the secondary indicator safety supervision index; m is the corresponding secondary indicator The number of ω _i is the weight of each third-level indicator corresponding to the secondary level; n is the number of the third-level indicators under the corresponding secondary indicator, and nor[] further performs the calculated index data of the highest level. The process of standardization processing.

That is to say, in the embodiment of the present invention, the index data of the highest level calculated can be further standardized to improve the accuracy of the data.

In the standardization process of the highest level of safety production index, Min-Max normalization, also known as Min-Max standardization, is one of the methods of standardization processing. The safety production index is performed by linear transformation method. The standardization process makes the value of the standardized production safety index fall within the (0, 1) range.

In order to reduce the case where the value of the highest level of the safety production index is normalized and the value is 0 or 1, the following embodiments of the present invention provide the following method for standardization of the deviation.

Specifically, the embodiment of the present invention normalizes the highest level of safety production index by using the following formula (5) and formula (6):

among them,

Where t is the highest level of safety production index after standardization, w is the highest level of safety production index before standardization, and w _min and w _max are respectively the predetermined periods of the acquired multiple analysis objects. The minimum and maximum values of the safety production index of all the highest levels, k ₁ and k ₂ are constant.

Through the above formula (5) and formula (6), the safety production index of the highest level is standardized to enable accurate analysis.

As a specific example, k ₁ may have a value of 0.1 and k ₂ may have a value of 1.1.

By standardizing all the highest-level safety production indexes by using the above-described dispersion standardization method, the number of “0” and “1” values of the safety production index after standardization can be reduced, so that the final evaluation and analysis results are obtained. Can be more comprehensive and accurate.

In this embodiment, if the indicator system for safety production is more than three layers, that is, the safety production index includes more than one intermediate level, the index value of the current layer and the weight of each safety production index of the upper layer may be calculated according to the calculation. The index calculation of the safety production indicators of the upper layer is calculated upwards in such a layer, and finally the safety production index of the highest level index is obtained.

In summary, in the embodiment of the present invention, a production environment security analysis method is provided, an index system index is obtained, and a hierarchical analysis method is used to construct a judgment matrix of a hierarchical index of a production environment, and a weight of each safety production index is calculated. Value, and standardize the collected historical data, and progressively calculate the highest level of safety production index to analyze the safety of the production environment. Through the above-mentioned analysis method of production environment safety, it is possible to compare the analysis results of different analysis objects in the same time period, and compare the analysis results of the same analysis object in different time periods, thereby enabling the safety of the production environment.
