Aiming at the decision of energy-saving renovation scheme of public buildings, based on the comprehensive income of energy-saving and carbon trading, this paper establishes the energy-saving, carbon reduction and economic benefit models of six technologies, such as: enclosure structure ( trading, this paper established the energy-saving, carbon reduction and economic benefit models of six technologies, such as: enclosure structure ( wall and form) renovation, lighting renovation, air conditioning optimization, air-conditioning optimization, energy-saving and carbon trading. wall and form) renovation, lighting renovation, air conditioning optimization, roof PV and boiler power replacement. The decision-making method of transformation scheme under the fluctuation of energy-saving and carbon trading is as follows The decision-making method of transformation scheme under the fluctuation of electricity price and carbon trading price is constructed with the help of multiple regression algorithm. Breaking through the traditional experience empowerment evaluation model, the optimal initial investment amount and the weighting and priority of various technology selection decisions are deduced. Breaking through the traditional experience empowerment evaluation model, the optimal initial investment amount and the weighting and priority of various technology selection decisions are deduced. Finally, the effectiveness of the method is verified by combining engineering cases, aiming to provide reference for owners to Finally, the effectiveness of the method is verified by combining engineering cases, aiming to provide reference for owners to flexibly respond to the energy and carbon trading market and precise energy saving.
收益风险是当前阶段我国PPP项目提前终止的首要非系统风险因素.基于风险决策理论和政企合作关系属性,结合工程实际案例统计分析建立PPP项目收益风险分担决策致因模型,并由德尔菲方法确定收益风险分担决策的因素清单,在此基础上利用贝叶斯推理原理和GeNIe工具提炼PPP项目收益风险分担决策的最敏感因素,并对营商环境、伙伴协同能力和收益风险分担决策之间的作用关系进行仿真计算与讨论,探究PPP项目合作主体的收益风险分担决策机理.研究成果期望为我国PPP项目风险决策与治理提供支撑.
通过对国内轨道交通工程竣工决算审计情况进行调研,对取得的样本工程竣工决算审计结果进行统计分析及探讨.结果表明,"审概比R"分布范围在73.0%~103.3%,总体平均值为88.6%.上述结果表征当前国内轨道交通工程领域投资执行情况良好.相关研究结论可为进一步深入开展轨道交通工程投资估算与控制、资金使用与管理、审计研究与实践等相关工作提供有力参考与数据支持.
职业道德缺失是造成承保风险的主要原因之一,而有效的测量工具对于提升职业道德至关重要.情景判断测验可反映从业人员面对道德困境时的真实行为.通过专家访谈和案例研究来收集关键事件,筛选、设置了8个典型和常见的情景.基于两轮德尔菲法函询、量表形成了32个真实度和区分度较高的行为反应,其有效性得到了83%的专家认可.研究将从三个方面改进测量工具,有效准确地评价从业人员职业道德,改善工程担保的市场环境和秩序.
老旧社区更新是围绕宜居目标对老旧社区不宜居现状问题的修正,二者高度统一,更新重点宜从建筑舒适性、安全稳定性、生活舒适性、环境适宜性、社区意识等角度梳理出问题清单,结合宜居目标建设体系保证更新的针对性.坚持"总体部署,分类实施"、"摒弃运动式更新,提倡'微更新'"、"以人为本,共同生产"的"系统谋划、渐近实施"的更新路径.
