针对复杂技术系统进化过程中需要消除有害因素的问题,提出用可供性描述技术系统与环境间的关系,并介绍了可供性模板和可供性矩阵的应用方法,在此基础上,提出了基于可供性的理想度描述方式,建立了可供性分析与TRIZ理论集成应用的计算流程。应用采煤机螺旋滚筒进化解决耗能问题的实例,验证了提出方法的正确性。 In order to eliminate the harmful factors in the process of evolution of complex technical systems, this paper proposes the relationship between the technical system of environment and the availability of sexual technologies, and introduces the application of the available templates and the availability matrix. On this basis, Based on the descriptive approach of the ideal degree of availability, the computational process of integrating availability analysis with TRIZ theory was established. The application of shearer spiral drum to solve the problem of energy consumption evidently proved the correctness of the proposed method.
