摘要
复杂技术系统中,在物质流、能量流和信息流的相互传递和转换过程中流的属性及类型变化会对其他流产生负作用,导致系统产生多种流问题。为解决这些流问题,文中在定义了物质流、能量流、信息流的基础上,结合流的属性,对流的类型进行了重新划分,并在此基础上建立了复杂技术系统流分析(AF-CTS)模型,利用基元模型对正常流及7类问题流进行了规范化表达。为了实现对抽象化的问题流进行定量计算,进而找到流问题的共性问题,提出了流梯度的概念,以此建立了复杂技术系统流问题分析与求解的模型。通过太阳能电池组件自动拆框机案例验证了模型的可行性。
In the complex technical system, changes in terms of flow attributes and types during the mutual transfer and conversion of material flow, energy flow and information flow have a negative effect on other flows and lead to multiple flow problems in the system. In this article, in order to solve these flow problems, based on the definition of material flow, energy flow, and information flow, combined with the flow attributes, the flow types are reclassified, and on this basis, the flow analysis(AF-CTS) model of the complex technical system is set up;the basic element model is applied to standardize the normal flow and those of 7 problems. In order to realize quantitative calculation of the abstract flows and find their common characteristics, the concept of flow gradient is proposed;the model for analysis and solution of the flow problem in the complex technology system is set up. The case of the automatic frame-dismantling machine for solar cell modules has verified that this model is feasible.
