目的 为了减少包装造成的环境污染，研究一种基于粗糙集理论的TOPSIS综合评价法，对包装的绿色程度进行评价。方法 构建包括环境、资源、能源、功能、经济等5个方面的绿色包装评价体系，利用粗糙集理论确定权重、TOPSIS方法，并对包装的绿色性进行打分排序，通过包装案例研究验证该方法的可行性。结果 通过粗糙集理论与TOPSIS法相结合的评价方法得到了客观的排序结果，并选择出最优的绿色包装方案。结论 基于粗糙集理论和TOPSIS的包装评价方法可对绿色包装进行评价，并得到了客观有效的评价结果。

The work aims to research a TOPSIS comprehensive evaluation method based on the rough set theory to evaluate the green level of the package, so as to reduce the environmental pollution caused by the package. The green packaging evaluation system was constructed with five aspects including environment, resource, energy, function and economy. The rough set theory was used to determine the weight and TOPSIS method, while the greenness of package was rated and ranked. The feasibility of this method was verified by a case study. Based on the evaluation method combining rough set theory with TOPSIS method, the objective ranking results were obtained and the optimal green packaging scheme was selected. Based on the rough set theory and TOPSIS packaging evaluation method, the green package can be evaluated and the objective and effective evaluation results are obtained.
