系统模型的网络描述与模型管理系统

SYSTEMS NETWORK MODELLING AND MODEL MANAGEMENT SYSTEMS

应用一般系统论的思想和方法，分析了基于系统动态平衡和系统模型网络式描述的统一的建模和求解方法，以及系统状态变量Ｘ与结构关系Ｒ的影响形式和函数描述，并提出了系统变化过程中系统模式的概念和一种矩阵描述方法．最后，讨论了基于网络模型的模型管理系统设计和初步应用情况．

Based on the general systems theory advanced by L. von Bertalabffy, this paper puts forward the possibility of formulating integrated modelling and its network representation of dynamic systems, and tries to give a normal defination of the functional relations between system state variables and system structure. Graph theory is applied to decompose large complicated systems with network into a set of individual small systems or networks that are connected with input and output and can be operated on microcomputers. We advanced the concept of system patterns and its matrix description by using function fitting processing. Finally, the model management systems design of network modelling and its application in the regional development planning is discussed.
