Using Lean Six Sigma to improve mobile order fulfilment process in a telecom service sector

This study proposes and follows a specific and systematic framework for implementing Lean Six Sigma (LSS) methodology in a telecom company in order to improve customer satisfaction by minimizing the company’s response time to customer requirements. The goal of this study was achieved by utilizing several LSS tools under five phases of the DMAIC methodology. Unlike previous studies in the telecom sector that used only qualitative method, in this study, both qualitative and quantitative methods were utilized to draw meaningful conclusions. As a result of the implementation of the LSS methodology, the average order fulfilment lead time for sales orders (SO) and value-added service (VAS) orders was reduced from 10.3 to 5.9 days and from 1.5 to 0.5 days, respectively. The reduction in lead time resulted in an increase in the sigma level for SO and VAS orders from 0.44 to 1.26 and from 0.73 to 2.66, respectively. These improvements were expected to lead to a financial benefit in savings of over $600,000 per year in operational costs, enhancements to customer experience and an increase in revenue generating opportunities. Moreover, this article enriches the existing literature on the application of LSS concept in the service industry, and helps the company to speed up the response to customer requirements.

中国电信“拆分”行为法理分析——从反垄断视角阐释

“拆分”是世界上大多数国家电信业反垄断的救济措施，从行政法角度分析，拆分是一种政府行为，体现了政府管理市场的经济职能；从公司法角度分析，拆分于某些情况下等同于公司法上的“分立”，与“合并”相对应；从反垄断法角度分析，拆分是一种反垄断的救济措施，中国电信的三次“拆分”推动了中国电信业的发展。但仍亟需反垄断法和电信法的出台。     

论第三方骚扰用户时电信运营商的侵权责任

方便快捷的移动通讯为人们的生活带来了方便,也带来了电信骚扰的烦恼。第三方用户对其他用户的骚扰情形越来越多,除了追究第三方的直接侵权责任之外,电信运营商也应当承担过错范围内的侵权责任。     

“碳关税”对中国经济的潜在影响

近年来,一些发达国家以应对气候变化为由,提出对进口的碳排放密集型产品征收特别的CO2排放关税,并将"碳贸易限制措施"扩大为"碳关税"壁垒。"碳关税"的开征必然对我国经济、出口贸易造成严重冲击。因此,我们应该积极主动参与相关国际规则的制定,优化出口贸易结构,加强低碳技术创新,实现向低碳经济的转型,以便充分地应对"碳关税"壁垒。     

Impact of the tariff concessions of the RCEP agreement on the structure and evolution mechanism of manufacturing trade networks

In the world’s largest free trade area, the Regional Comprehensive Economic Partnership (RCEP) agreement will gradually eliminate tariffs on over 90% of member countries’ goods over the next 36 years. We construct a tariff policy effects evaluation framework based on the complex network theory. In this framework, the standard Global Trade Analysis Project (GTAP) model is recursively extended to generate forecasted data of bilateral trade. Based on this, we model the RCEP manufacturing trade networks and analyze the response of its core–periphery structure to the tariff concessions. Then, we evaluate policy effects on the evolution of trade patterns based on motif analysis. Finally, we construct separable temporal exponential family random graph models (STERGM) to explore the influence path and degree of the new tariff agreement on the evolutionary mechanisms of trade networks.
