如何建立有效的物资供应体系

物资供应是环环相扣的紧密闭合链，任何一个环节出问题．都会使这条连续的链断裂。因此，建立一套行之有效的物资供应体系以保障物资的正常流动对于企业的正常经营而言至关重要。本文按照一般物资供应的流程，分别从物资采购，物流管理，库存管理，供应体系评价四个部分来论述如何建立一套行之有效的体系以保障物资的正常供应，并对我国企业的物流管理提出若干建议。     

How do internal capabilities and external partnerships affect innovativeness?

How do a firm’s internal capabilities and external partnerships contribute to its product and process innovativeness? How do their impacts differ? Based on the theoretical framework of exploitation and exploration, we develop an integrative model linking the impact of both internal capabilities and external partnerships on product and process innovativeness. Survey responses from Taiwanese biotechnology firms indicate that research and development (R&;D), marketing, and manufacturing capabilities have different effects on product and process innovativeness. Of the four types of external partnerships, only partnerships with universities and research institutes seem to add value, whereas partnerships with suppliers, customers, and competitors do not contribute to innovativeness. Moreover, marketing capability and customer partnerships have a positive interaction effect on product innovativeness, while manufacturing capability and supplier partnerships have a positive interaction effect on process innovativeness.     

Learning design and technology through social networks for high school students in China

The subject of design and technology was introduced to the curriculum for high schools in China 10 years ago. However, the teaching and learning of this subject have become difficult for both teachers and students because there is a lack of qualified teachers with design background to deliver this subject in a way to stimulate the learning interests of the students. This paper presents a research that is aimed at improving this situation by integrating the teaching and learning of design and technology within a computational environment as part of social networks sites. The purpose is to enable the collaboration among the students and interaction between teachers and students. In this research, a series of investigations were conducted, by following through several taught subjects in design and technology in prominent high schools in China. Based on these investigations, a theoretical framework for web-based design learning and teaching system in the style of social networking is developed, implemented and tested, emphasizing three features of design: innovation, collaboration, and interaction. This framework has been tested among high school students and teachers in a high school in Nanjing. It identified and validated necessary techniques and design features required to make an education-related social networking site effective and affective for the students and teachers. The results of this research indicated that social networking sites have significantly positive values in design education, especially for the collaboration and interaction on the subject of design and technology.     

地下综合管廊混凝土爆灰检测及加固

针对某市钢筋混凝土地下综合管廊的现浇顶板、侧壁出现的混凝土爆灰质量缺陷,为确保管廊结构的安全使用,采用钻心法、超声波法、沸煮试验、爆灰物质的化学成分分析等检测方法,对爆灰现象进行了检测。结果显示,混凝土中存在的块状氧化钙与水熟化后体积增大1倍~2.5倍,使得混凝土在强度未达到设计抗拉强度前在块状氧化钙体积膨胀应力作用下被拉裂,导致了此类质量缺陷的发生。分析了质量缺陷对管廊结构的影响,并对管廊结构进行了加固设计及处理,满足了结构的正常安全使用要求。研究结果可为类似爆灰缺陷的设计及处理提供参考。     

全尺寸评价方法标准化 提升油套管质量水平

油套管产品在油气勘探开发及生产过程中发挥着重要的作用,油套管产品质量的好坏直接关系着油气田的生产成本及使用寿命。通过分析油套管产品的使用现状,论述了油套管全尺寸评价标准在控制、提升油套管质量方面的重要作用。在分析、研究国际标准、油田工况、失效案例、科研成果的基础上,实现油套管全尺寸评价方法标准化,填补了我国油套管质量控制领域全尺寸评价标准的空白。全尺寸评价方法标准在油气田及生产厂推广实施情况表明,应用全尺寸性能评价标准,能够实现对油套管质量的全面控制,提升油套管产品质量,对油气勘探开发事业的发展具有重要的经济及社会意义。
