A study on X party material flow: the theory and applications

A thorough study of X party material flow (XPMF), its theory and its applications is conducted in this research. The X material flow concept is an extension of the material flow (MF) theory. To further elucidate that XPMF is one type of MF service model with PMF (party, material, flow) fractal structure and the characteristics of XPMF, we develop the three-pyramid synergetic operational model of XPMF. Through the analysis of several cases, we believe that OIR (Objective relational grade, Information sharing grade, and Resource complementary grade) is the set of order parameters that control and determine the formation of XPMF new structure and its degree of being ordered. Therefore it reveals the mechanism of XPMF formation and evolution. We also provide the principles and the methods for XPMF control.     

市场转型、社会资本与求职行为——关于大学生求职的个案研究

市场转型过程中,大学生的就业体现出就业模式市场化,分配主体多元化,就业形势严峻化。以往研究较多关注社会资本对求职的具体作用,而忽略社会资本运作的深层问题探讨。通过个案调查认为,社会关系网络是求职的重要机制,强关系、弱关系在求职中都可能提供信息和影响,市场因素的介入引起＂差序格局＂变迁,物质性交易是弱关系提供影响的维系力,强关系和弱关系将在完善的制度环境中共同充当信息桥的角色。     

AN ANALYSIS OF FACTORS AFFECTING CROSS DOCKING OPERATIONS

Using simulation, we examine the decisions in moving freight between inbound and outbound trailers in a cross dock. The decisions examined include direct versus indirect handling of pallets, number of open receiving doors, door layout, number of forklifts, size of cross dock and freight mix. This study provides useful insights on handling freight in a cross dock.

农资连锁经营应急机制下车辆调度研究

连锁经营,作为农资流通领域的新模式,逐步取代了原本散乱的农资零售格局。物流配送活动作为连锁经营理念的核心,是农资连锁经营能够成功运作的关键。但由于农业生产对农资产品的特殊要求,当消费者对农资产品有紧急需求,但就近的连锁店铺不能供货时,会给农业生产带来不利影响。本文引入应急概念,构建了应急车辆调度模型,来实现配送中心对企业配送系统内部各节点的库存的协调,使该连锁店能够快速响应消费者需求。     

物资采购中标准化,质量,计量工作的误区

从标准化、质量和计量三方面对物资采购工作中存在的误区进行了分析，指出物资部门在标准化，质量和计量方面存在的问题是导致库存物资上升，效益流失和油田成本居高不下的原因之一。     

Linking material and energy flow analyses and social theory

The paper explores the potential of Habermas' theory of communicative action to alter the social reflexivity of material and energy flow analysis. With his social macro theory Habermas has provided an alternative, critical justification for social theory that can be distinguished from economic libertarianism and from political liberalism. Implicitly, most flow approaches draw from these theoretical traditions rather than from discourse theory. There are several types of material and energy flow analyses. While these concepts basically share a system theoretical view, they lack a specific interdisciplinary perspective that ties the fundamental insight of flows to disciplinary scientific development. Instead of simply expanding micro-models to the social macro-dimension social theory suggests infusing the very notion of flows to the progress of disciplines. With regard to the functional integration of society, material and energy flow analyses can rely on the paradigm of ecological economics and at the same time progress the debate between strong and weak sustainability within the paradigm. However, placing economics at the centre of their functional analyses may still ignore the broader social integration of society, depending on their pre-analytic outline of research and the methods used.
