The current situation and problems of knowledge service and its supporting platform are discussed. In order to make product more competitive, a new framework of the knowledge service platform for modern design under distributed resource environment from a perspective of whole lifecycle of the products is proposed by the application of knowledge flow theory and knowledge service in this paper. This...
In order to realize fast location and detection of abnormal status during running of industrial furnace, especially abnormal status of firing, this article studies and designs a fault diagnosis expert system based on fault tree theory. Firstly, formalized definition of industrial furnace fault diagnosis expert system is given in the paper, then all component elements of the expert system are analyzed...
With the rapid development of science and technology, and the improvement of production safety and management standards, the use of expert system to bridge crane operator teaching simulation to train high quality personnel has become a pressing need. But it is hard to evaluate the train result. This paper aims at developing a bridge crane training system based expert system. The system includes some...
In this paper, an architecture using process inference for process planning in manufacturing process has been developed. This architecture is built based on a knowledge base, a resource database and an automatic reasoning kernel. In the automatic reasoning kernel, the generation process of process plan is analyzed and relevant reasoning rules, as well as reasoning engines are defined based on corresponding...
Reconfigurable manufacturing systems can be set up to produce small quantities of different products quickly and inexpensively, making them more responsive to changing requirements than traditional mass-production systems. One aspect of reconfigurability is autonomous self-configuration of manufacturing machines. For this purpose we propose a software application called a task-to-method transformation...
Through a series of lapping experiments, this paper determines variation relationship of lapping quality with relative lapping parameters. On this base and combining the variation relationship connecting lapping parameters we have mastered, we set a knowledge base for lapping experts system. In this paper, we developed the experts system with the aid of the knowledge base and the experts system can...
In this paper, we design a safety risk assessment expert system (SRAES) in petrochemical industry based on fault tree (FT). The expert knowledge is acquired through fault tree analysis (FTA) and stored in a knowledge base (KB) of the expert system. We adopt a rule and framework based reasoning (RFBR) method which is intuitive and conforms to the human thinking customary. This system will figure out...
Conceptual design is relative to customer requirements, ??taking customer demand as the direction?? has already become the dominant design concept. The framework and process model of integral conceptual design is provided, and a model of Requirement - Function - Principle - Structure is put forward. The mapping from requirement space to structure space is established by hierarchical automatic reasoning...
On the basis of the analysis of the research status about the knowledge aid at home and abroad, proposes an active knowledge support system. Presents some of the features of the system and applies it to garment structure design. The major contribution of this system is to establish a knowledge base for garment structure design and to avail the designers targeted domain knowledge to navigate through...
Fixture design is a complex and intelligent process, which demands professional knowledge and experience from the exports and designer. For a given work piece, the design solution space is large. With the development of artificial intelligence, there are increasingly methods to solve the problem of selection of optimal fixture design scheme, such as CBE. In the paper, the intelligent algorithms of...
For enduing the business enterprise capacity to respond to customer's need more accurately and quickly, so that the enterprise can further shorten the period of designing and manufacturing course, this text puts forward a technique route that would develop a three-dimensional parametric design system which is based on individual product customization under the network environment, meanwhile it makes...
In order to prevent and reduce coal mine gas explosion occurred, this paper firstly generally designed pre-warning expert system of coal mine gas safety which based on object-oriented. Secondly, it developed and realized the function of the system, including the establishment of a comprehensive database and knowledge base, the information in the system can more accurately be expressed through the...
Knowledge base is the core of expert system of mine safety pre-warning, and establishing knowledge base is a crucial work of building the expert system. The paper firstly has introduced knowledge classification and knowledge acquisition process of the expert system. Secondly, it has represented the expertise of mine safety by production rule, and then it has established the knowledge base by Microsoft...
Project risk assessment is a critical activity adopted in project risk management process to prevent risks and to enhance the success rate of projects. But so far it is a big challenge for project managers and experts to combine their expertise with intelligent technology to evaluate project risks due to insufficient risk related data. Based on this, a novel attempt to integrate analytic hierarchy...
In general, mechanic, electronic and software are developed independently by different design tools for the same mechatronic object (MO). As a consequence, it's difficult to find links between interrelated data which are needed by back-end tools like simulators. Even new concepts based on the idea of mechatronic objects are restricted to particular views of fabrication. Different views generate different...
This paper describes a hybrid intelligent system, called SMART-Agua, which is aimed to diagnose and give solution to water production problems in petroleum wells. Several innovative techniques like a multi-set based fuzzy algebra of qualitative uncertainties for expert system and perception-based data mining form the technological framework of the developed system. The diagnostic phase uses the expert...
