MODELING OF INTEGRATED MANUFACTURING SYSTEMS USING AN OBJECT-ORIENTED APPROACH

Traditional approaches to the modeling of complex manufacturing systems are expensive, time consuming, and of limited value. Recent developments in several areas (i.e., knowledge engineering, software engineering, modeling formalisms, engineering workstations, and database systems) are now to the point that a meaningful convergence can be crafted to yield a modeling environment far superior to any we have known in the past. Fundamental to this new approach to modeling are the recent developments in object-oriented programming and related technologies. A research team at Oklahoma State University has been exploring alternative approaches to the modeling and simulation of complex manufacturing systems since 1985. This paper argues for a fundamental paradigm shift in the development and utilization of models within a CEM framework.     

非封闭断层的试井解释方法

提出了“不完全‘镜像’反映”新方法.应用该方法解决了非封闭断层的试井解释问题.该方法不仅能够确定测试井到断层的距离,同时能够确定断层的导流能力.本文还定义了断层有效连通厚度和断层连通度的新概念.研究结果对油气藏描述、油气藏数值模拟以及油气田开发工作有重要的应用价值.
