Technical Field

[0001] This application relates to the technical field of environmental assessment, and in particular to a method and system for assessing the environmental effects of environmentally friendly materials. Background Technology

[0002] With increasing societal emphasis on environmental protection, the application of environmentally friendly materials is becoming more widespread. Whether to replace traditional materials with environmentally friendly ones requires an assessment of their environmental impact to determine the appropriate course of action. Currently, the environmental impact assessment of environmentally friendly materials primarily uses a single-variable method to compare one or a few target environmental indicators between environmentally friendly and traditional materials to determine their effectiveness. However, environmental protection targets involve multiple assessment indicators, and a bias cannot be applied to one over the other. Furthermore, the usage cost and service life of environmentally friendly materials may differ from those of traditional materials. Therefore, the aforementioned technologies suffer from insufficient assessment of the environmental impact of environmentally friendly materials. Summary of the Invention

Based on the type information of the target material, the important evaluation indicators corresponding to the target material are matched from the indicator form and identified as target indicators. At the same time, the indicator weight coefficients corresponding to each target indicator are determined to facilitate the setting of the contribution of each target indicator to the overall environmental protection effect. The target indicator values ​​of each target material are obtained and input into the environmental assessment calculation formula so that the target environmental assessment value is calculated after weighted summation based on the target indicator values ​​of each target material, which serves as the assessment value of the overall environmental protection effect of the target material. The comparative indicator values ​​of the comparative materials are obtained and input into the environmental assessment calculation formula so that the comparative environmental assessment value is calculated after weighted summation based on the comparative indicator values ​​of each comparative material, which serves as the assessment value of the overall environmental protection effect of the comparative materials.

This allows the carbon footprint index, energy consumption index, utilization rate index, recovery rate index, energy saving benefit index, pollution emission index, and economic evaluation index to be included in the evaluation scope when assessing the environmental effects of materials. Furthermore, the calculation of each evaluation index value takes into account the entire life cycle of the target material / comparison material and the product, thereby improving the comprehensiveness of the environmental effect assessment.

[0138] In this embodiment, the formula for calculating the environmental discrete parameter is:

[0139] ;

[0140] Specifically, based on the environmental protection deviation rate and the deviation rates of various indicators, the environmental protection discrete parameters are calculated according to the preset calculation formula to determine whether the target material surpasses the comparison material in many evaluation indicators. The smaller the environmental protection discrete parameters, the higher the comprehensiveness of the environmental protection effect of the target material.

[0141] S432: Based on the environmental protection discrete parameters and the preset discrete correction formula, calculate the discrete correction coefficient, and correct the environmental protection deviation rate based on the discrete correction coefficient.

[0142] In this embodiment, the discrete correction calculation formula is:

[0143] ;

[0144] Among them, when season , These are discrete correction coefficients. Based on the correction value, This is the scaling factor. For discrete reference limits, , Take a positive value; preferably, the base correction value is a positive value less than 1, such as 0.9. The scaling factor and the various coefficients in this embodiment can be set and adjusted according to actual needs to adapt to the technical requirements of different application scenarios.

[0145] The method to correct the environmental deviation rate is to multiply the environmental deviation rate by the discrete correction coefficient to obtain the corrected environmental deviation rate.

[0146] Specifically, based on environmental discrete parameters and a preset discrete correction formula, discrete correction coefficients are calculated. The discrete correction coefficients are set with discrete reference limits to restrict the upper limit of the influence of environmental discrete parameters on the discrete correction coefficients, scaling factors to constrain the degree of influence of environmental discrete parameters on the discrete correction coefficients, and a basic correction value. This improves the scientific nature of the calculation using discrete correction coefficients. The environmental deviation rate is corrected based on the discrete correction coefficients and then compared with a preset first deviation threshold, which improves the scientific nature of the environmental assessment results.

[0150] S60: Based on the initial assessment sequence identifier, define each candidate material as the target material one by one, and execute the above steps S10 to S40 to determine the environmental deviation rate and environmental assessment results of each candidate material.

[0151] Specifically, based on the initial assessment sequence identifier, each candidate material is defined as the target material, and the above steps S10 to S40 are performed to conduct environmental effect assessments of each candidate material with the initial comparison material in turn, thereby obtaining the environmental deviation rate and environmental assessment results of each candidate material.

[0153] Specifically, each candidate material that meets the environmental assessment criteria in the initial material selection optimization task is selected, sorted from highest to lowest environmental deviation rate, and a secondary assessment order identifier is set. At the same time, the initial comparison material is redefined as candidate material and a secondary assessment order identifier is set. The candidate material with the lowest environmental deviation rate is defined as the secondary comparison material, so as to carry out the secondary material selection optimization task.

[0154] S80: Based on the secondary evaluation order identifier, define each candidate material as the target material one by one, execute the above steps S10 to S40, screen each candidate material whose environmental assessment results are qualified, and sort them from high to low according to the environmental deviation rate to generate a list of preferred materials.

[0155] Specifically, based on the secondary evaluation order identifier, each candidate material is defined as the target material, and the above steps S10 to S40 are executed again to screen each candidate material whose environmental assessment results are qualified. The materials are then sorted from high to low according to the environmental deviation rate to generate a list of preferred materials, so as to assist in the selection decision-making of environmentally friendly materials.
