An internet-based information and monitoring platform for the specific requirements of geotechnical engineering projects is presented. The platform is based on a hybrid-model approach consisting of a model-based information management system and a resource management system, the latter also referred to as DCMS. Project key information can be accessed via the main user interface, the 'graphical navigator'. The graphical navigator provides also a direct access to additional information in the DCMS. Prompt reac-tion in exceptional situations as well as in daily work gets an extensive support. In practical applications it has been proven that this platform seems to be an adequate tool especially for risk assessment and management in geotechnical engineering projects. Components and advantages of the platform as well as ex periences from the applications are presented and discussed in the paper. 展开更多

针对无土栽培基质生产过程中基质混合不充分和采用离散元法时因模型过大、颗粒数过多而导致仿真结果不精确的问题,通过建立相似理论搅拌模型,利用赫兹-明德林(无滑移)模型(Hertz-Mindlin(no slip))建立肥料与土壤颗粒仿真模型,对影响混... 针对无土栽培基质生产过程中基质混合不充分和采用离散元法时因模型过大、颗粒数过多而导致仿真结果不精确的问题,通过建立相似理论搅拌模型,利用赫兹-明德林(无滑移)模型(Hertz-Mindlin(no slip))建立肥料与土壤颗粒仿真模型,对影响混合器搅拌均匀性和效率的放料方式、搅拌式混合器叶片间距和搅拌器转速3个变量因素进行离散元仿真分析。结果表明,相似理论搅拌模型可用于仿真模型的缩放,达到减少计算量,提高仿真精度的效果;采用平铺的放料方式,由于上层颗粒会在重力的作用下加速颗粒间的混合,混合效果更佳;相似模型中叶片间较佳间距为20 mm;叶片转速在50 r/min时搅拌混合效果和经济性最佳;与人工搅拌相比,搅拌式混合器大大提高了混合效率和效果,且可以避免出现盲区。仿真分析结果可为搅拌式混合器的设计与优化提供理论参考。 展开更多

The objective of this research is to examine the antecedents and consequences of cost management systems (CMS) design effectiveness of manufacturing businesses in Thailand. The effect of CMS design effectiveness on cost information quality is investigated. Moreover, the effect of cost information quality on business success is investigated. Furthermore, executive management support and cost accountant competency are assumed to become the antecedents of CMS design effectiveness. Electronics manufacturing businesses in Thailand are samples of the research. A mail survey procedure via the questionnaire was used for data collection from accounting controllers. The results indicate that CMS design effectiveness has a positive significant effect on cost information quality. Moreover, cost information quality also has a positive significant effect on business success. Additionally, both executive management support and cost accountant competency have a positive significant effect on CMS design effectiveness. 展开更多

This paper analyses the necessity of developing variation information management of construction project. The structure scheme of variation management system has been put forward, which is based on intranet or internet scheme, with the structure of Browser or Server. The system consists of eight modules, which are variation account management, variation application, variation evaluation, variation execution, variation price management, variation report management, variation information query and system maintenance. With this system, remote management and controlling in real time for variation of construction proiect can be carried out. 展开更多
