在实际操作中，采用近似求解法，既简便又可完全满足实际应用的需求。采用平

In actual operation, the approximate solution method is adopted, which is simple and can fully meet the needs of practical applications. Although the square root method is simple and easy to implement, it widens the gap between the weight values ​​of various indicators, and the results have a large deviation compared with the actual survey results. The survey results of subway passenger satisfaction can directly reflect the actual situation of passenger satisfaction with the subway, so the square root method is not applicable. In contrast, the sum-product method is more suitable, and it will not be very different from the original survey results

In practice, the approximate solution method is used, which is simple and can fully meet the needs of practical application. Although the square root method is simple and easy to use, it widens the gap between the weight values of each indicator, and the results have a large deviation from the actual survey results. The results of the subway passenger satisfaction survey can directly reflect the actual situation of passenger satisfaction with the subway, so the square root method does not apply. In contrast, the product method is more appropriate and does not differ significantly from the original findings.

In practical operation, the approximate solution method is simple and can fully meet the needs of practical application. Although the square root method is simple and easy to use, it enlarges the difference between the weight values of each index, and the result has a large deviation compared with the real survey results. The survey results of subway passenger satisfaction can directly reflect the actual situation of passengers' satisfaction with the subway, so the square root method is not applicable. In contrast, the sum product method is more suitable and does not differ greatly from the original survey results<br>
