CIM环境中的决策支持系统的研究

The Decision Support System in the CIM Environment

决策支持系统(DSS)是计算机集成制造(CIM)环境中计算机信息系统的核心,它直接支持计算机集成制造系统(CIMS)的生产规划与控制。本文讨论了CIM环境中的DSS的特点、结构。分别详细分析了基于递阶层次结构的DSS和基于分布式结构的DSS.并进一步探讨了用面向对象(object—oriented)的设计思想来构造分布式决策支持系统(DDSS)。本文还阐述了仿真模型在DSS中的重要作用。

Decision support system (DSS), is the kernel of the computerised information system in the computer integrated manufacturing (CIM) environment and supports directly the planning, scheduling and control in the computer integrated manufacturing system (CIMS). The paper discusses the features and structure of the DSS in the CIM environment, analyzes the DSS with hierarchical structure and the DSS with distributed structure, and further discusses how to construct the distributed decision support system (DDSS) with object-oriented development style. The paper also emphasizes the importance of the simulation model in DSS.
