AN ANALYSIS OF SUPPLY CHAIN COLLABORATIONS AND THEIR EFFECT ON PERFORMANCE OUTCOMES

This research examined how operational outcomes, relational outcomes and business performance are affected by a collaboration project between buyers and suppliers in a supply chain. It is hypothesized that interdependence of knowledge and process, supply chain partner insight, and the level of collaboration between the firms affect the outcomes of a collaboration project. Survey data from buyers and suppliers from a wide range of industries and organizations were used in this analysis. Among these participants, higher levels of collaboration led to improvements in operational and relational outcomes, which together led to improvements in asset utilization, competitive position, organizational performance, and profitability.     

DEFINING AND OPERATIONALIZING SUPPLY CHAIN PROCESS INTEGRATION

Integration has been recognized as critical to successful supply chain management. However, an extensive literature review revealed no consensus in its conceptualization. The current study attempts to address this research gap by providing a better definition and operationalization of supply chain process integration. With empirical support, it is proposed that internal and external supply chain process integration should be treated as two separate constructs, each comprised of two dimensions: connectivity and simplification.

试论建筑工程全过程造价的控制措施

我国现代化建设进程加快使得工程项目增多,成本造价控制成为工程建设项目的难题。而工程造价控制效果的好坏常受到多方面因素影响,立项、设计、施工、竣工等每个过程都会影响到造价的高低。这些因素的影响作用也决定了造价管理控制时应当建立良好的管理思路,针对这一点,本文重点分析了建筑工程全过程造价控制的相关策略。     

OUTPUT FLUCTUATIONS PERSISTENCE: DO CYCLICAL SHOCKS MATTER?

The aim of this paper is to identify the different sources of persistence of output fluctuations. We propose an unobserved components model that allows us to decompose GDP series into a trend component and a cyclical component. We let the drift of the trend component switch between different regimes according to a first‐order Markov process. To calculate an appropriate p‐value for a test of linearity we propose a bootstrap procedure, which allows for general forms of heteroscedasticity. The performance of the bootstrap is checked by means of a Monte Carlo simulation. Our study concerns the USA. We find that cyclical shocks appear to play an important role on the observed persistence of output.     

水泥混凝土路面碎石化在老路改造施工中的应用

随着使用年限的增长和超载车辆的增加,多数水泥路面破坏严重而丧失整体的承载能力,且板块之间错台严重,致使其行车舒适性较差,急需维修改造以满足现代交通的需要。     

不确定性环境下的战略变革模型

在一个不确定性环境里,如何发现企业的战略老化并及时变革使之生存下去是摆在企业管理者面前的一道难题。在不确定性环境中,要降低不确定性,形成战略时就要做到在任何单位时间内均拥有大量的战略假设;拥有范围较宽的战略假设且是从正确的来源获得战略假设。形成战略后可采用使机会最大化的否证法进行战略选择。战略实施实际上也是对战略假设的再检验过程。在一定的时间间隔上对战略进行评估,如果出现战略老化的迹象或支持所选择战略的任何假设改变了,那么就转向另一种战略。     

企业应用推广创新方法绩效评价指标体系研究

创新方法是支撑企业创新活动的重要工具,我国自2007年以来,先后在多家企业开展以TRIZ理论、六西格玛管理、QFD、精益生产等单一或多种创新方法的应用推广,以目标为导向,分析企业应用创新方法产生创新绩效影响因素的基础上,确定以"科学性、系统性、可操作性、发展性"为主体的绩效评价指标体系构建原则,建立了科学规范的评价指标体系,应用层次分析法(AHP)计算了指标权重,确定了模糊综合评价方法及过程,提出了创新方法示范企业管理策略,为创新方法管理工作和示范企业培育提供参考和借鉴。     

油气管道环焊缝新型修复技术研究

为了寻求适应高钢级油气管道环焊缝缺陷的新型修复方法,克服传统修复技术的局限性,提出了电弧增材制造技术用于油气管道环焊缝修复的可行性。首先,对激光熔覆、冷喷涂、电弧增材制造3种新型修复技术进行对比分析后,采用电弧增材制造技术进行实验研究;其次,在X80管道环焊缝处沿轴线截取22 mm厚的试样,并在环焊缝处设计坡口角度为60°,坡口深度为11 mm的缺陷,采用电弧增材制造冷金属过渡工艺、ER50-6焊丝进行修复实验;最后,对修复试样进行力学实验测试,并对实验数据和断口形貌进行分析。实验结果表明,电弧增材制造修复后试件抗拉强度最高达639 MPa,强度与管体基材匹配。研究结果表明,电弧增材制造技术用于X80油气管道环焊缝缺陷的修复是可行的,具有沉积效率高、成本低、力学性能能满足修复要求的特点,对于高钢油气管道环焊缝缺陷修复的可行性和经济性具有重要的现实意义。
