摘　　要：为了减少耦合协调度计算的主观性、揭示装配式建筑项目中精益施工能力与效益间的耦合协调状态,通过改进耦合协调度模型,进行装配式建筑精益施工能力与效益的耦合评估研究.基于文献分析和理论推导,揭示了精益施工能力与效益的耦合机理;在文献分析基础上,通过专家评审,建立了精益施工能力与效益的评价指标体系;采用熵值法,计算各指标权重,再基于改进耦合协调度模型,评价精益施工能力与效益的耦合协调度.收集全国不同地区14个装配式建筑项目施工的样本数据,分析这些项目中精益施工能力与效益的耦合协调度.结果表明,从项目维度看,目前多数装配式建筑项目的精益施工能力与效益耦合协调度在0.609与0.761之间,处于初级或中级协调水平,个别项目耦合协调度低于0.5,处于濒临失调状态;从区域维度看,南、北方的装配式建筑项目精益施工能力与效益耦合协调水平差距明显,这主要归因于使用意愿、推广力度和经济条件的差异而非装配式建筑的推广时间.基于结果分析,进一步提出营造装配式建筑精益施工能力与效益转化的良性生态,完善现有精益施工能力培训体制.研究结果为实现装配式建筑精益施工能力与效益的良性耦合提供了理论参考和对策建议.To reduce the subjectivity associated with coupling coordination degree calculation and reveal the coupling coordination status between the capability and benefits of lean construction(LC) in prefabricated building projects,a coupling evaluation study of LC capability and benefits of prefabricated building was conducted by improving the traditional coupling coordination degree model.The coupling mechanism of LC capability and benefits was revealed via literature analyses and theoretical deduction.Based on literature analyses and expert review,an evaluation index system of LC capability and benefits was established,and each index was weighted using the entropy method.Based on the improved coupling coordination degree model,the coupling coordination degree of LC capability and benefits was evaluated.The sample data of 14 prefabricated projects in different regions was collected to analyze the coupling coordination degree of LC capability and benefit in these projects.The results show that current LC capability-benefit coupling coordination degree of most prefabricated projects is between 0.609 and 0.761,which is at the primary or intermediate level of coordination;the coupling coordination degree of certain projects is less than 0.5,which is on the verge of imbalance.There is a significant gap between south and north regions in terms of LC capability-benefit coupling coordination level of prefabricated projects,mainly due to differences in willingness to use and economic development,rather than the promotion time of prefabricated buildings.Based on the result analysis,this study suggests creating a benign ecology for the transformation between LC capability and benefits and improving the existing LC capability training system.Study results provide theoretical references and suggestions for achieving the benign coupling between LC capability and benefits of prefabricated building.
