【摘要】 运用多目标模糊层次分析法,构建了石油石化企业节水项目综合评价指标体系和评价模型,研究了评价指标的隶属函数、隶属度确定的数值算法及合成算法,用Visual Basic 7.0设计了计算机评判软件系统,并通过典型案例进行了应用验证,结果表明:所建指标体系从技术、经济和社会生态环境三方面客观、真实地反映了节水项目的综合效果;所建评价模型反映了节水项目综合评判的模糊性、综合性和多层次性,为评判项目的整体优劣和投资决策提供了依据。更多还原

【Abstract】 Using the method of multi-aim fuzzy analytical hierarchy process,the indexes system and the judgment model of comprehensive evaluation of the water-saving projects in petrolic or petrochemical enterprises were established.The author studied the subordinate function,the numerical method to confirm the subordinate degree of the judgment indexes and the method of combination operation.The evaluation software system was verified in application.The result indicated the established indexes system reflected the integrated effect of water-saving project in impersonality and reality through three aspects of technology,economy and social environment.The established judgment model reflected the characteristics of fuzzy,integration and multi-hierarchy in comprehensive evaluation to water-saving project,also offered the scientific basis for evaluating the overall excellence or badness of the project and investment decision-making.更多还原
