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. Natural man-made complex system composed of natural system and man-made system is a dynamic complex system of feedback, and there are a series of problems to be studied in the development of the system.Aiming at the problem of system development, this paper puts forward that through the realization of personnel responsibility and goal of each subsystem, Aiming at the development of natural man-made complex system based on the general goal and the natural man-made complex system combining system simulation and “learning by doing”, taking the medium- and large-scale biogas energy project of Taihua farms in Pingxiang City of western Jinggangshan as an example, A series of practical problems in the development of biogas energy engineering system were established. The system dynamic simulation equations were established through the combination of table functions and selection functions. The biogas development and application of sub-simulation models were used to simulate different problems one by one And achieve the goal of efficient development of regional biogas energy engineering systems through the integration of system simulation with “learning by doing” and the realization of the responsibilities and goals of various subsystems of companies, universities, managers and agricultural technicians, government and farmers. The results of this study have theoretical and demonstration significance for the development of natural artificial composite system.
