自然人造复合系统的开发原理与途径——以区域大中型沼气能源工程系统开发为例

Developing theory and approach of the natural and artificial complex system—A case of regional large and medium-sized biogas engineering system development

由自然系统和人造系统所构成的自然人造复合系统是一个反馈动态复杂系统,其系统发展中存在系列问题待研究.针对系统开发问题,提出了通过各子系统人员责任和目标的实现,实现系统总目标的自然人造复合系统开发原理,新建了系统仿真与"干中学"结合的自然人造复合系统开发途径.以井冈山西部萍乡市泰华养殖场区域大中型沼气能源工程为例,针对其中沼气能源工程系统开发系列实际问题,通过表函数和选择函数等多种形式函数的结合,建立系统动力学仿真方程,用沼气开发和应用子仿真模型逐步建模法对各不同问题逐一进行仿真实验,实现系统仿真与"干中学"相结合,并通过公司、大学、管理人员与农业技术员、政府、农户等各子系统责任和目标的实现,达到区域沼气能源工程系统高效开发总目标.此研究结果对自然人造复合系统开发有理论和示范意义.

The natural and artificial complex system composes of natural system and artificial system is a feedback dynamics complexity system. In this paper, a new system developing theory of the natural and artificial system is presented to realize the whole aim of the system by realizing the duty and aim of each sub-system. And we exploit a natural and artificial system developing approach by integrate system simulation and ＂learning by doing＂. Taking the case of the biogas engineering area of the Taihua Swine Farm in Pingxiang, Jiangxi Province, to some actual problems in the biogas engineering systems, create system dynamics simulation equations and do simulations of each problem by the step-by-step modeling of biogas developing and application using table functions, delaying functions and ＂if-then-else＂ functions, etc. Integrating system simulation and ＂learning by doing＂, realize the whole aim of the system by realizing the duties and aims of all sub-systems for enterprises, universities, management organizations, agricultural technicians, the government and farmers. The research has significance for the natural and artificial systems developing.
