The inference algorithm is the most important part in intelligence system because the level of intelligence in the system is decided by it. By means of the mutual benefit for inference algorithm of expert system ,fuzzy logic and neural network ,the combinatorial inference technology which is organically composed of these three parts is put forward for inference mechanism in intelligence system. The optimization decision model is also set up. In order to bring all the advantage of every inference algorithm into play and overcome the disadvantage of single inference algorithm the common expert knowledge base is applied to organic combination and concurrent operation of all inference algorithm. In order to realize knowledge share the inference results are optimized by decision technology optimization. The research results show that the organized combinatorial inference and optimization can be applied in engineering practice effectively and is benefit for raising the inference level. 相似文献

Design of GIS-based monitoring and maintenance decision support system for urban sewage pipe network
Monitoring and maintenance of sewer system is important to city water environmental management. A method for pipeline monitoring and maintenance decision support system (PMMDSS) based on geologic information system (GIS) and decision making system (DSS) is developed for upgrading sewer system maintaining efficiency. Visual basic (VB) and standardized Active X components are employed in PMMDSS, which selected SuperMap Objects as the development platform. PMMDSS integrates the spatial and model system to achieve the decision analysis for the sewer system monitoring and maintenance. An application Software is developed based on a case study in Yuechi Country of Sichuan Province. The software can be used to dynamically monitor the heath condition and provide an optimum visual decision making platform for the city sewer system. 相似文献

Large particle size gravel strata layer is very difficult for TBM construction which brings about a series of problems for EPB TBM advancing in Beijing Metro. Cutting wheel is an important component of EPB TBM and cutting wheel with reasonable structure is essential for EPB TBM to advance steadily and effectively in large particle size gravel strata. In-situ EPB TBM advancing tests are carried out in large two adjacent shield interval where the strata conditions make it possible to find out the most efficient cutting wheel structure by monitoring key parameters through Real-time Information Management System. Based on the analysis and comparison of advancing efficiency, strata adaptability of key parameters and tools wearing, the following conclusions can be obtained: 1) Spoke cutting wheel has better strata adaptability and higher efficiency than panel cutting wheel as well as more advantages in controlling tools wearing. 2) open ratio ranging from 55% to 65% is the reasonable for cutting wheel. 3) Advancing speed and earth pressure are very important for EPB TBM construction. Compared with panel cutting wheel, spoke cutting wheel can obtained higher advancing speed and more stable earth pressure in tests. However the change of earth pressure should also be paid attention when EPB TBM advancing in fast speed. The advancing speed should be controlled in the range of 20 to 60 mm/min. 相似文献

In existing equipment vehicle transmission test bed can be controlled only by 8031 SCM and data can not be transmitted from SCM to PC. In order to take most advantage of available equipment, data transfer between PC and Multi SCM is put forward. By this way, torque of eddycurrent dynamometer can be controlled by PC programs and satisfy the needs of torque convert experiment. Making use of Dynamic Link Library 8250 registers can be read and written directly. Programs can set the ninth bit easily without Microsoft Communication Control. Data are transmitted between PC and Multi SCM though RS232 COM successfully by using Visual Basic programs. Cost and time are sharply reduced. 相似文献

Systems in human bodies do not work independently when conducting physiological activities and making reaction to external environment,as their functions will be regulated by the multidimensional network structure composed by nerve,endocrine,and immunity system.The three systems each performs their own functions and realizes joint control so that the functions of each cell,organ and system can be normally achieved and thus forms the theory of nerve-endocrine-immunity system. This theory combines nerve,endocrine,and immunity system in an organic way,integrating the relationship of mutual regulation among the three functional systems of human bodies. It informs people of how the three systems of nerve,endocrine,and immunity influence,coordinate and restrict each other to together regulate functional activities of the human body and maintain the stability of internal environment. The generation and development of this theory manifests that modern science also gradually starts exploring regulation of the whole body at the same time of emphasizing in-depth local microexamination,providing a new meaningful research model for understanding the general function of bodies from the level of molecules. In this paper,the author concludes relevant conditions for the realization of the regulation function of this network as composed of three parts: structure foundation,neural master control,and micro-substance foundation,and elaborates on them respectively. 相似文献

The Dynamic Causality Diagram methodology is a new probabilistic reasoning model based on Belief Network. To some extent, it is similar to the Belief Network in structure. So that knowledge from one can be transformed into the other on some conditions. To begin with, this paper discusses the similarities and differences between them, and finally presents a transformation algorithm from Dynamic Causality Diagram into Belief Network. The algorithm is composed of two parts: a mapping algorithm of structure and a generating algorithm of conditional probability tables. 相似文献

With increased emphasis on the natural environment by stakeholders, the need for explicit consideration and incorporation of environmental strategy has been critical within organization strategic plans and their operations. While in the scope of green supply chain management strategy decision is more important. The authors study the components and elements of green supply chain management and how they serve as a foundation for the decision framework. The structure of framework is network hierarchy, so the authors apply analytic network process (ANP) tool which was first introduced by Saaty. An illustrative example is used to explore the application of the ANP technique to this problem. 相似文献

休闲农业产业集群动力机制分析 总被引：4，自引：0，他引：4
发展休闲农业是调整农村产业结构、促进农村发展的有效途径,研究休闲农业产业集群动力机制对休闲农业的发展具有重要意义。为此,在对产业集群动力机制理论框架进行分析的基础上,依据系统动力学原理对休闲农业产业集群动力机制的构成主体和演变过程进行分析。得到以下结论：产业集群发展内在逻辑就是要素、动力机制和竞争优势之间的内在作用的过程。休闲农业产业集群是一个以要素禀赋、产业链、创新能力为形成基础,以市场需求为诱因,以政府培育为作用路径的良性动力循环,并在产生、成长和成熟3个阶段形成基础由静态要素需求逐渐变为动态要素需求,而诱因和路径不变的动力机制。 相似文献
