Application of Design for Six Sigma tools in telecom service improvement

Abstract

Six Sigma is a systematic methodology aiming at operational excellence. Under the general umbrella of Six Sigma, DMAIC and Design for Six Sigma are usually be implemented to improve product and process quality. Facing quality bottlenecks in traditional improvement projects, tools in Design for Six Sigma is an efficient way to achieve better results. In this paper, to meet the high-quality requirement of key clients, a telecom service system improvement project is illustrated by redesigning troubleshooting and service delivery processes in company Shanghai Telecom Co. Ltd. (ST) with the aid of some Design for Six Sigma tools. Company ST improved its service system performance and obtained significant economic benefits from this project implementation. Four key factors that affect the success of Design for Six Sigma tools application in improvement projects are discussed at last.     

城市间创新联系及创新网络空间结构研究

将基于牛顿原理的引力模型首次应用到城市间创新联系的研究中并对其进行修正,建立城市创新引力模型;结合网络分析法,按照八大经济圈的划分标准对我国287个地级及以上城市间的创新联系及创新网络空间结构进行深入探讨。结果显示,各经济圈创新网络城市间创新联系紧密程度存在差异,以经济发达城市为核心的创新网络空间布局基本形成,块模型揭示了城市子群内创新联系较子群间紧密的特征。     

乡村振兴战略实施中基层少数民族精英的融入机制与作用研究

乡村振兴战略实施过程中,“国家—民族精英—少数民族群众”的结构框架下,不同主体之间的关系更加复杂。根据村庄人口外流程度和村庄内部机械结合强度的不同可将村庄分为四种类型。类型不同,村庄内部民族精英的存在状态及相互关系也不尽相同。民族精英融入乡村振兴战略要注意人的参与和规则的供给。民族地区的乡村能否振兴,一个“度”的把握很关键,即少数民族民众的动员程度。民族精英的重要性恰在于组织与引领少数民族民众。国家要依赖民族精英,但同时也要注意民族精英挟“民族话语”自重的动机与目的,通过体制机制创新来规范民族精英的活动,防止民族精英的利益集团化。     

VMI模式下考虑促销努力的销量回扣契约模型研究

本文在促销努力影响市场需求,单周期季节性产品销售环境下,分析了集中式供应链和供应商管理库存(VMI)供应链中的供应商供货量和零售商促销努力水平的决策问题。在无契约VMI供应链中引入滞销产品补贴的销量回扣契约,讨论了零售商参与合作的条件,结论表明该契约能够提高VMI供应链的绩效并改善其收益;而VMI供应链中的成员采用改进的销量回扣契约进行协调时,有可能实现集中式供应链的最优收益。最后,通过算例验证了引入滞销产品补贴的销量回扣契约能增加供应商供货量和零售商促销努力水平,大幅度地提升VMI供应链的总收益。     

Early Sales of Seasonal Products with Weather‐Conditional Rebates

Some retailers of seasonal products adopt weather‐conditional rebate programs to induce early sales and increase profits. In such promotions, customers who buy the product in an advance preselling period are offered rebates if a pre‐specified weather condition is realized during the later normal selling season. We investigate the potential benefits of these programs for retailers. We show that the weather‐conditional rebate program can increase sales by price discriminating among a customer's post‐purchase states. Taking advantage of the early sales, it can also reduce the inventory holding cost and ordering cost, and hence can increase the retailer's expected profits. In addition, we numerically investigate the sensitivity of the rebate program's effectiveness to the model parameters and illustrate its advantages over an advance‐discount policy.     

社会主义核心价值体系的哲学本质及其社会功能

社会主义的核心价值体系,从其直接的呈现形态来看,最重要的是以现实价值为基础,以理想价值为导向,形成整个社会的价值尺度和价值追求。社会主义核心价值体系的社会功能表现为导向和规范功能、调节和协调功能、人格塑造功能、定向整合功能。     

求导向型农技推广机制研究文献综述简

随着农业科技发展环境的改善和发展,创新性农业技术推广模式不断涌现,通过推广机制创新为不同农业经营主体提供适用性强、匹配度高的农技服务对提升农业技术利用率具有重要的作用。本文从农户分化与兼业行为、农技的供需契合、农户对技术采纳行为及影响因素、参与式农技推广模式、需求导向型农技推广产生背景及理论内涵等五个方面回顾分析了国内外有关需求导向型农技推广研究的进展情况,表明与传统农技推广研究相比,需求导向型农技推广在研究内容、方法和范围方面存在滞后性。     

面对WTO争端解决机制中的报复:遵从抑或效率违约

WTO争端解决机制中的报复机制是胜诉方的"杀手锏"和最后救济手段,它的威慑性确保了WTO争端解决机构通过的专家组和上诉机构报告中的建议和裁决在大多数情况下能够得到切实遵守。然而,由于重要的国家安全、政治及文化等利益的驱使,也存在效率违约现象。我国在WTO的争端不断增多,面对WTO争端解决机制中的报复,选择遵从还是效率违约这一问题便具有了重要的理论和实践意义。     

SPECIAL ISSUE： NATIONAL IDENTITY IN THE COURSE OF GLOBALIZATION National Identity Crisis in Developing Countries in the Global Age and Its Causes

20世纪90年代以后,随着冷战的结束,世界图景发生了巨大变化,全球性族裔冲突和民族矛盾更加凸显,这使得国家认同成为现实和学术关注的重点M题。在全球化时代,要较好地处理国家认同问题,需要在基础理论层面对国家认同发生的逻辑,即民族认同的性质、国家认同的性质、陶家认同对地方民族认同以及国家认同危机发生的逻辑等进行彻底的分析。从社会认同需求的角度分析,全球化对现代世界权力结构的改变削弱了发展中国家的自主性,特别是发展中国家的现代化尚未完成,面临着社会转型的风险,呈现出结构性失衡,从而降低了国家整合治理能力,使得国家认问对民族成员的意义进一步被削弱,并引起了地方民族认同的兴起,进而导致了发展中因家的国家认同危机的发生。     

Elderly chinese and their family caregivers' perceptions of good care: a qualitative study in shandong, china

This study aims to understand what older Chinese people with chronic illness and their family caregivers perceive to be good care, and to compare perspectives of those living in rural and urban areas. We conducted semistructured interviews with 24 care recipients and 23 caregivers in Shandong, China. Two major themes were identified: (a) filial piety as the standard, and (b) modifying cultural ideals to meet reality. There was overall consistency in perceptions of study participants. Variations between rural and urban elders' perceptions appear to reflect differences in socioeconomic development and institutional structures.
