Innovation of Engineering Surveying Course Teaching for Road and Bridge Engineering Technology Majors in Higher Vocational Colleges

Engineering surveying is an important course for road and bridge engineering technology majors in higher vocational colleges.With the advancement of science and technology,engineering surveying technology is also constantly developing,so the theoretical knowledge and professional skills that students need to master are also becoming increasingly complicated.To stimulate the students’interest in learning the course,it is necessary to continuously introduce innovative teaching methods into the course.In this paper,the importance of teaching innovation in engineering surveying courses of road and bridge engineering technology majors in higher vocational colleges and the knowledge system that students need to master are analyzed.Subsequently,innovative strategies are proposed to help improve the students’mastery of engineering surveying.

Organelle Structures: Bridging Strategy and Technological Processes

The shifting requirements as imposed on operations ma nagement require adjusting and tailoring the organisational structure to meet ma rket demands. However, translating these requirements directly into hierarchical structure will not ensure the integration of processes across organisational un its and guarantee desirable performance. Therefore, management and management li terature wonders: · How should we connect processes to the external environment within a strategi c framework · Which organisational structures do meet performance requirements · Which choices and freedom do we have within organisational structures · How and when do we implement organisational structures That the hierarchical structure does not meet as such the performance requiremen ts nor did it relate to these became already clear during case studies performed in the ’70s. The conclusion was drawn that organisational changes should affect working processes before they proof to be viable. This required the development of new approach through empirical studies and base d on literature. This led to the development of the organelle structure. The org anelle structure should connect to the strategy and the product flow. Thereto, a decision model has been developed for revealing these relations and the practic al implication. During a number of case studies this methodology has been refined and includes t he strategic choice between variants for the organelle structure with their own performance capabilities; we distinguish about 20 variants ranging between the f unctional organisation and the product flow organisation. These ranges of choice s however can be connected to different order entry points, stemming from logist ic concepts. This extends the performance to improved lead-times and improved c ontrol. Strategic choices relate the organelle structure to external performance criteria dictated by product/market-combinations: · lead-time · quality · costs and internal choices for performance criteria: · flexibility · productivity · resource utilisation · innovative performance. Case studies reveal the drastic improvements of the performance of operations an d manufacturing. The paper will discuss a few of these implementations to demons trate the impact. They also show how one derives the hierarchical structure from the choice for the organelle structure. Organelle structures do bridge the link of an industrial company to its environm ent and the internal possibilities, dictated by characteristics of product flow and process execution. The link to the environment results in a strategic framew ork for assessment of alternatives and possibilities. Choices for organelle stru ctures depend strongly on choices on the order entry points of the hardware flow and the specification flow. The evaluation of the characteristics takes place a gainst the strategic framework ensuring competitive advantage as well as a high probability of factual implementation and performance improvement.

BIM技术在桥梁设计阶段的应用探讨

在现阶段我国桥梁工程项目建设中,因为面临着更高的建设要求,桥梁结构也更为复杂,在承载能力以及耐久性方面同样也需要得到良好保障,如此一来,需要重点围绕桥梁工程项目建设全过程进行严格把关。从桥梁工程项目设计阶段来看,如果设计方案不合理,存在着较多的隐患和缺陷,必然也就会影响后续桥梁工程项目整体施工效果,所以,切实提升桥梁工程设计水平极为必要。BIM技术作为当前工程行业中至关重要的新型技术手段,确实在多个方面发挥着积极作用,将其应用到桥梁工程项目中,必然也可以更好地优化设计方案。
