摘　　要：厌氧消化系统是一个多变量、强耦合及高度非线性的超复杂系统,复杂系统传统的手段是采用结构型模型的建模的方法,如本文提到的厌氧消化1号模型(ADM1),本文描述了传统模型对复杂系统的适用范围和局限性,以及对神经网络、专家系统和系统动力学三种不同的系统分析方法的综合比较,提出了系统动力学对于研究厌氧消化这种超复杂系统是较为合适的观点,并在本文中通过以乙酸降解过程表述了系统动力学模型的建立方法。Anaerobic digestion system is a very complex system. There are many variables in the anaerobic digestion system, and have the relationship of strong coupling and strong nonlinear among all the variables. The traditional analysis method for the complex system constructs the model by building the structure model, such as Anaerobic Digestion Model No.1 (ADM1).In this paper, it shows the applicability and limit of the structure model, and draws the conclusion that system dynamic is the best fit for the anaerobic digestion system by balancing the Neural Networks System,Expert System and System Dynamic. It gives the model of acetate degradation as an example of the process of constructing system dynamic model.
