How to quantify the degree of environmental pollution

The quantitative method of grade is to convert the grade of each factor evaluation into a numerical quantity in order to obtain a comprehensive evaluation score.

There are 10 factors of labor intensity and labor environment, and each factor is divided into 4 5 levels. The method of quantifying grades is to assign a score to each grade, and the numerical difference between grades is 1, and the score of 1 grade is 1,..

A 4-level score is 4. Some factors include 0 and 0 5, such as the classification standard for exposure to dust hazards from 0; The manual labor intensity grading standard is from 0 5 level, then the corresponding score is 0 or 0 5. There are 11 factors in the two elements of labor responsibility and labor skills, and each factor is divided into 9 levels.

The method of quantifying the grades is as follows: the numerical difference of each grade is 1, the score of the 1st grade is 9, and the score of the 2nd grade is 8,......A score of 1 is given on a 9-scale scale. The weight of the factor refers to the weight coefficient of the four major elements of each element and the proportion of each factor in each element.

The weights of the factors and factors should be determined according to the degree of influence of each factor and factor on the nature and role of the post. It exists objectively and is subject to the production characteristics of the enterprise. The setting of factor weight factors should be determined according to the characteristics of various types of jobs in the enterprise, and the evaluation results should be able to basically and correctly reflect the labor differences of the types of jobs in the entire production process of the enterprise.

The weight coefficient of each element should also be determined according to the characteristics of each industry. For example, the weight coefficients of the four basic elements in the above table of metallurgical enterprises are: labor responsibility 0 28, labor skills 0 22, labor intensity 0 26, and labor environment 0 24.

For chemical enterprises, labor responsibility is 0 40, labor skills are 0 20, labor intensity is 0 15, and labor environment is 0 25. The weight of the factors is divided into four categories: the most important, the important, the relatively important, and the general according to their importance and the degree of harm in the whole production process.

In this way, the weights corresponding to each of the four types of weighting factors are .

Quantification The same indicator is still accumulating and qualitative, one indicator has become another, and the quantification will become qualitative when the accumulation reaches a certain level, and qualitative is the beginning of a new quantification.

Daily work bai

As the so-called "quantitative du" in life: it refers to the goal or task zhi is specific and clear, and can be measured clearly. Root.

According to different situations, it is manifested in the number of large and small amounts, specific statistics, range measurement, length of time, etc.

The so-called quantization is to discrete the amplitude of the instantaneous value obtained by sampling, that is, to use a set of specified levels to express the instantaneous sampling value with the nearest level value. A sampled image is simply spatially discretized into an array of pixels (samples). The grayscale value of each sample is still a continuous change of an infinite number of values, which must be converted into a finite number of discrete values and given different codewords in order to truly become a digital image.

This transformation is called quantification.

Quantitative analysis is also made.

It is an analytical method that is qualitative.

BAI risk analysis, prioritized risks, quantitative analysis. Quantitative analysis has spread throughout all aspects of our lives, mostly used in finance, economics and other fields. In this way, it can help us to measure risks and benefits more conveniently and intuitively, for example, on the quantitative analysis of **, which is reflected in various trend charts.

Knowing what the essence of quantification is at present, I believe that quantitative indicators can greatly improve work efficiency.

The work is divided into items that can be recorded and expressed by numbers, so as to measure the efficiency, quality and achievement of the work.

For example, your dream this year is to make a lot of money, and it is very vague how much a lot is, and it is difficult to settle whether it is realized or not.

For example, my goal this year is to earn 100,000 yuan, and 100,000 yuan is a quantifiable goal, which will help achieve the goal.

2) Division of labor: who will complete this year's goal, and each of these people will determine what they should do this year. 3) process; Know who to do what and when, and how to do it.

4) Indicators: at which stage, by whom, and by what method this year, how much benefit should be produced. 5) Standard:

For managers) to apply methods and set standards! Managers and employees work closely together to ensure that work is carried out according to standard design procedures.

I don't know much about your work, the company's plan to quantify, as long as there are the above 5 elements in the plan, it should be called "quantitative".

I hope it helps you a little, and if not, don't laugh at me!

Quantization is to discretize the amplitude of the instantaneous value obtained by sampling, that is, to use a set of specified levels to express the instantaneous sampling value with the nearest level value.

Or the range of continuous variation of the amplitude of the input signal is divided into a finite number of non-overlapping sub-intervals (quantization level), and each sub-interval is represented by a definite value in the interval, and the input signal falling into it will be output at that value, so that the continuous input signal becomes an approximate signal with a finite number of discrete value levels.

The difference between adjacent quantization levels is called the quantization order, and any analog sample value that falls within the range of no more than half of the previous or next quantization order is greater than or less than a certain quantization level, respectively, is expressed by the quantization level, and the difference between the sample value and the quantization level is called the quantization error or quantization noise.

The so-called quantification, just.

Complex is the scripture. The instantaneous value obtained by sampling is discretized by its amplitude, and the instantaneous DAO sampling value is represented by the nearest level value by a specified set of levels. "Quantification" in daily life refers to the fact that the goal or task is specific and clear, and can be clearly measured.

Depending on the situation, it can be expressed in terms of quantity, specific statistics, range measurement, length of time, etc. For example, four trillion expenditures, 9.6 million square kilometers, eight hours, and the completion of the task ...... on March 31
