Abstract

This paper demonstrates how design assistance for engineering processes of computer based systems is realized with the SEA-Environment. SEA allows to specify engineering processes in an unambiguous way using extended Predicate/Transition Nets (Pr/T Nets) as the underlying formal model. Since Pr/T Nets are executable, tool support for a design process is realized easily via simulation of the process specification. By linking a user defined abstract graphical representation to the Pr/T Net, the interface of a design assistant can be tailored to the needs and preferences of engineers. Furthermore, artificial neural networks are integrated into the SEA-Environment. Neural networks provide learning facilities, that allow decision making during a design process, for instance the selection of an appropriate tool and its parameters among a set of alternatives, automatically. An advantage of this approach is that the huge amount of knowledge needed for various decisions does not have to be acquired a priori but can be gathered during the use of an engineering environment.

智能设计辅助与SEA

本文论述了如何利用SEA-Environment实现基于计算机的系统工程过程的设计辅助。SEA允许使用扩展谓词/转换网(Pr/T网)作为底层正式模型，以明确的方式指定工程过程。由于Pr/T网是可执行的，因此通过模拟过程规范可以很容易地实现对设计过程的工具支持。通过将用户定义的抽象图形表示连接到Pr/T网，设计助手的界面可以根据工程师的需求和偏好进行定制。此外，还将人工神经网络集成到SEA-Environment中。神经网络提供学习设施，允许在设计过程中做出决策，例如在一组备选方案中自动选择合适的工具及其参数。这种方法的一个优点是，各种决策所需的大量知识不需要先验地获得，而是可以在工程环境的使用过程中收集。
