给出制定维修等级的依据及对其内容的要求,提出野战防空和要地防空地空导弹武器系统维修等级划分为四级(日常维护、基层级、支援级、基地级)的建议及各级维修具体内容,给出设计预防维修周期需考虑的因素,及该周期长短对武器系统作战有效度的影响,提出维修等级方案设计与武器系统技术方案设计互相渗透、同步进行才能达到优化的观点. Given the basis for the establishment of maintenance level and the requirements of its content, put forward the field defense and air defense ground to air missile weapon system maintenance level is divided into four levels (routine maintenance, grass-roots level, support level, base level) recommendations and at all levels The specific contents of maintenance and repair are given. The factors to be considered in the design of preventive maintenance cycle and the effect of the length of the cycle on the effectiveness of the weapon system are proposed. The viewpoint that the design of the maintenance level scheme and the design of the weapon system can penetrate and synchronize can be optimized.
