项目摘要

A new design methodology for plant systems design was investigated using knowledge engineering concept. And an expert system for plant systems design was also developed based on the developed design methodology. The results obtained are summarized as follows:1. The new concept of design methodology for plant systems was established. It is found that the design steps for designing plant systems can be devised into the following steps. Namely, 1) searching the candidates of machineries consisting the plant, 2) determining the numbers and capacities of the machineries, and 3) selecting the optimal combination of the machineries considering the initial and operational cost.2. Based on the above understanding, the new design method was developed using the ogject-oriented knowledge representation concept which was one of knowledge engineering techniques. This method was adopted to an expert system for the design of plants. The application of an integer programming method was also investigated. And a hybrid-type expert system was built coupling the knowledge engineering technique and the mathematical programming method. The smalltalk-80 language was also applied to the piping design for plant systems.3. The expert systems for the actual design of a marine power plant and a cogeneration plant were developed using the above method. The effectiveness of the developed systems was well ascertained.4. The systems were implemented on a workstation Sun-3/110C which was found to serve as an effective intelligent terminal for plant systems design.

使用知识工程概念研究了工厂系统设计的新设计方法。并基于所开发的设计方法开发了电站系统设计专家系统。所得结果总结如下： 1．建立了工厂系统设计方法的新概念。发现设计工厂系统的设计步骤可以设计为以下步骤。即，1）搜索组成工厂的候选机械，2）确定机械的数量和容量，3）考虑初始成本和运营成本选择机械的最佳组合。2．基于上述认识，利用知识工程技术之一的面向对象的知识表示概念开发了新的设计方法。该方法被采用到工厂设计的专家系统中。还研究了整数规划方法的应用。并结合知识工程技术和数学规划方法建立了混合型专家系统。 Smalltalk-80语言也被应用到工厂系统的管道设计中。 3．采用上述方法开发了用于船舶发电厂和热电联产厂实际设计的专家系统。所开发系统的有效性得到了很好的确定。 4．该系统在工作站 Sun-3/110C 上实施，该工作站被认为是工厂系统设计的有效智能终端。
