大型供应链设计的基本数学模型与算法研究

随着信息技术与全球经济一体化的发展,供应链管理成为全球管理科学的研究热点。本文在分析国内外各种关于供应链设计的数学模型与算法的基础上,提出了具有普遍性意义且简单易行的MIP供应链设计的数学模型以及求解供应链问题的有界变量广义上界算法。实例计算表明,提出的模型和方法是可靠实用的。     

我国制造业产能利用率测度与影响因素研究——基于十个重点行业

选取制造业的十个重点行业,使用2001-2014年的面板数据,运用数据包络分析法(DEA)对其产能利用率、技术效率和设备利用率进行了测算,结果显示:我国制造业的部分行业存在严重的产能过剩问题;非金属矿物制品业、黑色金属冶炼和压延加工业等传统行业的产能利用率较低;通信设备、计算机及其他电子设备制造业等新兴行业的产能利用率相对较高.剖析制造业产能过剩的影响因素,发现市场需求与产能利用率存在显著的正相关关系,资本密集度、就业水平、开放度、金融支持与产能利用率有显著的负相关关系.     

新常态下供销社经营模式的转型与创新研究

随着我国新型四化的深入推进,农村经济建设迈入了新阶段。在新常态下,供销社的迫切任务是加快转型升级,切实提高为农服务能力。因而这就要求我们既要把握好传统业务,又要善用改革和创新的思维开拓新型业务,用业务经营发展促使供销社转型升级。面对我国经济发展新常态,供销社过去长期积累起来的服务“三农”的宝贵经验遇到了很大的挑战,在经营过程中所暴露出的经营方式、手段等方面都存在着很多弊端,进而阻碍了供销社的生存与发展。供销社要想走为农服务的道路,转型与创新势在必行。基于经济发展新常态,分析供销社在发展中存在的突出问题;研究供销社进行转型与创新的必要性;最后归纳总结供销社经营模式的创新途径。     

县级政府、供应链管理与农产品上行关系研究

基于中国13省87个电子商务进农村示范县的调研材料,分析政府项目驱动下农产品上行问题。实践表明,政策利好为县域农产品电商发展提供了试错空间,“S2B2C”的供应链管理模式对农产品上行的推动作用明显。但是,多数县级政府未能认识到供应链管理之于农产品上行的作用,普遍存在政府治理方式滞后、公共服务网络不健全、农产品区域公用品牌缺乏、冷链等基础设施投入不足等问题。因此,为有效推动农产品上行,政府应进一步推动“公私合作”、构建一体化的公共服务、注重品牌营销、优化产品供应链管理。     

五代十国货币史初探

五代十国时期,由于铜钱缺乏,战争频繁,政治腐败,开支浩大,各国统治者为了挽救财政危机,往往铸行虚值大钱、铁钱以及铅锡等劣币,从而引起了通货膨胀、钱币贬值、物价飞涨、人民受损,这可作为今人的历史教训。     

Open innovation and quality management: the moderating role of interorganisational IT infrastructure and complementary learning styles

This study seeks to explain the influence of quality management on the relationship between open innovation and performance. We propose that, to contribute to open innovation performance, an organisation’s commitment to quality improvement must rely on the combination of its own resources and capabilities and its open innovation partners’ resources and capabilities. Specifically, we examine the moderating role of an interorganisational IT infrastructure and the complementarity of learning styles among an organisation committed to quality improvement and its supply network. Using data from 270 managers of European firms, our results show that the negative effects of quality management on open innovation performance can be overcome by complementing the organisation’s learning style with that of its open innovation partner, particularly, its supply network, and, most importantly, obtaining information technologies compatible with those of its supply network members.     

公共服务供给机制创新:北欧的改革实践与启示

提供公共服务是政府的主要任务。供应与生产的区分,说明政府不可能也没必要包揽所有的公共服务。北欧各国按照事权财权匹配和公共服务效率原则,通过建立和完善府际责任分担、公共财政保障、公私伙伴合作、公众参与提供、服务质量监督等机制,从而有效地满足了公共服务需求。他们的成功实践启示我们:公共服务制度的建立和完善,必须合理划分各级政府公共服务责任,建立以公共服务为导向的公共财政支出体系,充分发挥社会和民间力量在提供公共服务方面的作用。     

茶叶供应者质量安全认知与行为分析——基于浙江500位茶叶供应者的问卷调查

茶叶质量安全问题制约了中国茶叶产业的可持续发展。通过构建茶叶供应质量控制主要环节结构体系,对各环节供应者质量安全认知与质量控制行为考察,利用TOPSIS模型对茶叶供应质量控制关键点进行分析,归纳出当下茶叶供应链质量控制关键环节、重要环节和普通环节。研究表明:茶叶种植者、加工者质量安全基本认知程度较低;供应者在产前环节、种植管理环节、加工环节、储运销售环节中的部分质量控制行为薄弱。茶叶供应者素质良莠不齐是质量安全认知层次不同的主要原因,因此,需对不同供应者有针对性地进行质量安全认知强化。     

The other side of Malaysia’s enviable economic and multiethnic stability: the obstinate resilience of ‘money politics’

Many governments, in their zeal to progress and deliver the fruits of development, are caught in a web of unsavory habits and practices that impair not only their international image but also domestic legitimacy. One such perennially persistent and resilient disease is ‘money politics.’ Taking Malaysia as a case study, we note that despite sustaining a remarkable record of economic and multiethnic stability, the country has also been helpless in mitigating this obstinate issue. In this article, it is posited that the phenomenon is not a new or recent portent but has actually persisted even prior to independence. We shall then contend that unless the ruling Barisan Nasional (BN) coalition government attaches greater priority in stamping out this political bug, the country’s otherwise enviable development trajectory and the quest to reach a ‘developed nation’ status via its Vision 2020 declaration, even if fulfilled, are not cause for celebration, given its implications to the country’s economic sustainability and multiethnic stability.     

Cloud manufacturing system for sheet metal processing

Abstract

Cloud computing is changing the way industries and enterprises run their businesses. Cloud manufacturing is emerging as an approach to transform the traditional manufacturing business model, while helping the manufacturer to align production efficiency with its business strategy, and creating intelligent factory networks that enable collaboration across the whole enterprise. Many production planning and control (PPC) problems are essentially optimisation problems, where the objective is to develop a plan that meets the demand at minimum cost or maximum profit. Because the underlying optimisation problem will vary in the different business and operation phases, it is important to think about optimisation in a dynamic mechanism and in a number of interlinked sub-problems at the same time. Cloud manufacturing has the potential to offer decision support as a service and medium of communication in PPC. To solve these problems and produce collaboration across the supply chain, this paper provides an overview of the state of the art in cloud manufacturing and presents a model of cloud-based production planning and production system for sheet metal processing.
