基于计算机控制的生产过程自动化系统设计过程的模型

MODELS OF THE DESIGN PROCESS FOR COMPUTER CONTROLLED AUTOMATION SYSTEMS

本文使用工程生存周期模型描述了自动控制系统的设计进程;讨论了设计过程的三类模型:项目一阶段模型、流图模型和设计层模型;介绍了三类设计工作:方案设计、操作设计和辅助设计;将非技术性需求纳入设计过程,从而获得完全的设计层模型,这是软件工程环境EPOS的理论基础。

The design process for computer-controlled automation systems is described using a phasemodel of the project lifecycle. Three types of models of the design process are discussed- project-phase models, flow diagram models and design models with decomposition or abstraction strata. The consideration of 3 classes of design activities are introduced; conceptual, operational and auxiliary design.The description of non-technical influences and requirements is brought into the design process, so thai a complete model with design levels is obtained.This model forms the theoretical basis for EPOS, which is Engineering and Project management Oriented development support System.
