从要素体系和指标体系2个方面分析了装备保障信息化体系的组成,指出装备保障信息化体系是一种耗散结构。采用信息化指数对装备保障信息化程度进行定量评价,利用耗散结构理论的基本观点,构建了装备保障信息化体系演化模型。在此基础上,提出了加强体系建设的开放性、注重体系建设的协调性、提高体系建设的预见性、注重体系建设的渐进性等建议。 The paper analyzes the composition of information security system of equipment support from two aspects of the system of factors and indicators, and points out that information security system of equipment support is a dissipative structure. The informational index is used to quantitatively evaluate the degree of information security of equipment support. Based on the basic viewpoint of dissipative structure theory, an evolution model of equipment support informationization system is constructed. On this basis, some suggestions are put forward, such as strengthening the openness of system construction, paying attention to the coordination of system construction, improving the predictability of system construction and paying attention to the gradual progress of system construction.
