In this paper,we constructed the model of a reverse supply chain with the OEM as the leader and the third-party recycler responsible for the remanufacturing activities,and analyzed,respectively under the decentralized and centralized decision-making,the influence of carbon tax,scale effect of the remanufacturer and carbon emission reduction patent on the optimal decision-making of the members on the reverse supply chain using the Stackelberg game theory,and had a numerical simulation study via MATLAB.The result showed that:under both decentralized and centralized decision-making,carbon tax and scale effect of the remanufacturer could promote supply chain carbon emission reduction;under decentralized decision-making,carbon tax could only reduce the price of carbon emission reduction patent and increase remanufacturer output,but not reach the optimal carbon emission reduction effect;and under centralized decision-making,when the consumer prefers the remanufactured products over the carbon emission rate of the remanufacturing process,the supply chain members would jointly develop and use carbon emission reduction patents,and the supply chain output would increase and tilt toward selling remanufactured products,thus increasing profits while enhancing the carbon emission reduction effect.Therefore,through proper contract design,we could distribute the supply chain profits reasonably,so that the total supply chain profits could be increased,the carbon emission reduction effect improved,and overall supply chain coordination achieved.
针对现有具备原地90°换向功能的四向穿梭车的换向机构复杂、可靠性不高的缺点,深入分析和挖掘了ICAM S.r.l公司专利中公开的穿梭车轮系换向机构及其核心零件——槽轮的设计和运动原理,通过对该形锁合凸轮机构的运动分析、槽轮运动模型建立、数值计算和试验验证,得到较理想的槽轮沟槽轮廓模型.此外,还探讨了该换向机构存在的问题和不足,并提出可行的解决措施,为四向穿梭车的研发和换向机构的设计提供参考、借鉴和指导.
"双碳"政策背景下,如何维衡"电商经济发展"与"绿色低碳发展"成为亟待解决的问题.以苏州大学为切入点,基于计划行为(TPB)与刺激机体行为(S-O-R)理论,从高校群体参与回收行为视角出发,构建高校学生参与快递包装回收行为与意愿的结构方程模型.运用SPSS26.0与AMOS26.0统计分析软件,借助结构方程对有效样本数据展开实证分析,探究与验证影响苏州大学学生参与快递包装回收的影响因素.实证结果表明,强制规范通过整体动机影响行为意向进而促进实际行为,意识导向与发展安全通过行为意向影响实际行为,条件设施直接对实际行为产生显著影响.最后依据实证分析结果提出相应的对策建议.
