摘要：There has been an increasing interest in integrating decision support systems (DSS) and expert systems (ES) to provide decision makers a more accessible, productive and domain-independent information and computing environment. This paper is aimed at designing a multiple expert systems integrated decision support system (MESIDSS) to enhance decision makers' ability in more complex cases. The basic framework, management system of multiple ESs, and functions of MESIDSS are presented. The applications of MESIDSS in large-scale decision making processes are discussed from the following aspects of problem decomposing, dynamic combination of multiple ESs, link of multiple bases and decision coordinating. Finally, a summary and some ideas for the future are presented.

摘要：The inspection of engine lubricating oil can give an indication of the internal condition of an engine. By means of the Object-Oriented Programming (OOP), an expert system is developed in this paper to computerize the inspection. The traditional components of an expert system, such us knowledge base, inference engine and user interface are reconstructed and integrated, based on the Microsoft Foundation Class (MFC) library. To testify the expert system, an inspection example is given at the end of this paper.

摘要：In CAD/CAM integration, the source information must be produced from the conceptual design of product. A gear box conceptual design expert system for planomilling machines was developed which solved the problemof information integration from conceptual design to detail *** problem-solving model for the conceptual design of mechanical products is *** system architecture and the function of the main modules are described. The basic structure for the object-oriented knowledge representation and its formalizsd representation arediscussed in detail. Finally, implementation of the scheme layout and its control flow chart are explored using several samples.

摘要：As a key application of smart grid technologies,the smart distribution network(SDN)is expected to have a high diversity of equipment and complexity of operation *** awareness(SA),which aims to provide a critical visibility of the SDN,will enable a significant assurance for stable SDN ***,the lack of systematic evaluation through the three stages of perception,comprehensive,and prediction may prevent the SA technique from effectively achieving the performance necessary to monitor and respond to events in *** analyze the feasibility and effectiveness of the SA technique for the SDN,a comprehensive evaluation framework with specific performance indicators and systematic weighting methods is proposed in this ***,to implement the indicator framework while addressing the key issues of human expert scoring ambiguity and the lack of data in specific SDN areas,an improved interval-based analytic hierarchy process-based subjective weighting and a multi-objective programming method-based objective weighting are developed to evaluate the SDN SA *** addition,a case study in a real distribution network of Tianjin,China is conducted whose outcomes verify the practicality and effectiveness of the proposed SA technique for SDN operating security.

摘要：讨论了工程CAD专家系统特点，提出其一般结构。为了解决如飞机制造协调等复杂工程问题，实现一种层次分布式CAD专家系统（HDES）结构。HDES由元级、任务级两个水平的分布式专家系统组成：任务级专家系统（T－ES）主要用于应用设计，它们在其自己的设计领域中执行；元级专家系统（M－ES）则处理合作。介绍了层次－框架－规则的专家系统组织表示方法。

摘要：The necessity and feasibility of an expert system for carbide-tool utilization are analyzed and a practical system named CUES(carbide-tool utilization expert system ) is developed and realized. The system concept, module structure, data management, inference strategy and the interface design of the system are discussed ***. The system would be useful not only for the preparation of tool bank of FMS or CIMS, but the for the proper application of cemented carbide tools in conventional machining Processes.

摘要：Beacuse the practical mathematic model of rolling process can't be built accurately,this paper established an expert system to control the rolling steels' gauge by adjusting the setup roll open, which combined the experience of theoreticians and operators. The system applied the expression method of rule-skeleton+rule-body', and selected an appropriate non-exact reference model and self-study algorithm. The whole system, including auxiliary routes, is designed in Borland C++. Some experiments on this system have been done, and a good result has been achieved.

摘要：An approach to feature-based parametric design for die and mould is proposed in this *** assembly relationship and parts of the die and mould are described by *** dependent relationship of features is described by parent-child operator *** feature shape and location can be modified by design *** expert system is used for deriving a geometry of the features which satisfies the given *** approach provides a more natural and convenient method of representing a parametric model of the die and mould.
