为了解决SaaS模式供应链管理系统在推广应用中存在的问题,该文在分析总体拥有成本(Total cost of ownership,TCO)构成的基础上,建立了考虑风险因素的TCO模型(即RTCO模型),提出了定量的风险成本计算方法,并通过案例做了验证。研究结果表...为了解决SaaS模式供应链管理系统在推广应用中存在的问题,该文在分析总体拥有成本(Total cost of ownership,TCO)构成的基础上,建立了考虑风险因素的TCO模型(即RTCO模型),提出了定量的风险成本计算方法,并通过案例做了验证。研究结果表明,SaaS模式的供应链管理市场与理论优势存在成本悖论,主要由风险因素引起;风险成本可以量化,且与评价主体的风险偏好有关;RTCO可以为用户提供定量的决策依据。展开更多
随着移动互联网的快速发展及新基建、数字经济等国家战略政策的引导,我国数据中心快速发展。预计到2025年,能耗需求持续高速增长,占比将超过4%。在国家3060双碳目标及最新的分时电价政策驱动下,数据中心配置一定比例的储能系统,提高新...随着移动互联网的快速发展及新基建、数字经济等国家战略政策的引导,我国数据中心快速发展。预计到2025年,能耗需求持续高速增长,占比将超过4%。在国家3060双碳目标及最新的分时电价政策驱动下,数据中心配置一定比例的储能系统,提高新能源接入比例,利用削峰填谷降低用电成本,将成为数据中心节能减排的极佳选择。结合国内典型地区的分时电价政策,对锂电池应用于数据中心削峰填谷的场景进行总拥有成本(Total Cost of Ownership,TCO)分析,为绿色低碳的数据中心建设提供参考。展开更多

In this paper, a new quantitative method is put forward to accomplish the task of total assessment on the Microeconomic level which analyses all of the quantitative and qualitative factors with regard to the supplier selection. A Microsoft Excel based new application kit named TOCO Total Assessment Tool is introduced. It can calculate the direct cost and the indirect cost conveniently and can help to evaluate the performance of candidate suppliers. To use the tool, the first module called Total Cost Analysis Module is introduced to calculate the total cost of supplier selection, and then the second module named Supplier Evaluation Module is used to evaluate the performance of each supplier. Finally, the results from these two modules are transferred to the Final Comparison Module to get the final decision-making results. In this paper, the supplier selection related factors are discussed; the method of using the tool is illustrated in detail. It is shown that scientific usage of the TOCO Total Assessment Tool can make the decision-making processes of supplier selection in international procurement transparent, easily calculated, and objective. At the end, a practical case is given to clarify the procedure of using the tool.展开更多
