工程项目质量的团队激励机制研究

针对多个承包商的工程质量团队激励机制设计问题,根据工程质量管理的特点,利用委托-代理理论,采用线性激励契约,建立工程项目质量的团队激励模型。结合算例,运用粒子群算法求解不同分部分项工程质量评价权重和承包商风险态度组合下的团队激励模型,得到其最优均衡解。结果表明,承包商风险态度相同时,质量评价权重越大,业主应给予的激励强度就越大,承包商为实现自身利润最大化,其努力达到的工程质量水平也越高;选择风险中性的承包商比选择风险厌恶的承包商更有利于实现业主效用的最大化。

基于三角模糊数的高校图书馆服务质量评价指标权重值研究

针对现在高校图书馆服务质量评价指标测量方法不客观的问题,依据三角模糊数的基本原理,结合图书馆的评价指标,利用图书馆服务质量的调查问卷,通过数据采集,统计分析服务质量评价指标的重要性调查结果,构造三角模糊函数,用重心解模糊化法求解权重值的大小,利用权重值来量化图书馆服务质量评价指标的重要程度,进而分析读者对图书馆需求的变化。

Quality Synthetic Evaluation of Urea Formaldehyde Foam Substrate in Turf Establishment

[Objective]The aim of this study was to explore the feasibility of three kinds of urea formaldehyde foam substrate in tall fescue establishment as well as to study on evaluation of turf quality.[Method]The visual estimates,ecological quality estimates and utility quality estimates were used as the 1st level indicators,and the density,color,texture,uniformity,green period,cover degree,biomass,emergence energy,growth rate and turf-forming time were used as the corresponding 2nd level indicators.With T.L.Satty＇s method Analytic Hierarchy Process（AHP） and the fuzzy synthesis evaluation method,the weight ratio of matrix was obtained and the synthetic evaluation result was accorded with facts,then it could be regarded as the satisfying value of weight.[Result]The quality of three covering soil treatments was better than that of uncovering treatment and conventional treatment,the quality synthetic evaluation of F1 was the best,which was about 0.770.[Conclusion]Urea formaldehyde foam substrate showed high quality for turf establishment,which could be further spread and applied.
