| 摘要: |
| 针对T/R组件在备件库存、保障模式以及维修策略方面的特点，建立了两级维修保障体制下相控阵雷达的效费比随机Petri网模型。首先对随机Petri网性能存在的不足进行分析，并对其进行改进，引入抑制弧和全局时间，建立了多部件条件下不同连接方式的系统Petri网模型；其次以多部件当中的k/N系统连接方式为基础，建立了相控阵雷达系统的Petri网模型并进行实例验证；最后对模型中的使用可用度和单位时间维修费用进行分析。实例仿真表明，该Petri网模型可信度高，可以分析基层级和基地级初始备件数量、维修策略参数(m,NG)对系统保障效能的影响，克服了传统解析方法建模的局限，更加贴合实际。 |

| Abstract: |
| According to the characteristics of spare parts′ inventory,support mode and maintenance strategy of T/R module,the stochastic Petri nets model with cost-effectiveness under two-echelon maintenance policy is built.Firstly,the shortcomings of stochastic Petri nets model are analyzed and improved.Then by introducing inhibitor arc and global time,the Petri nets model of multi-component in different connections is established.Secondly,the Petri nets model of phased array radar system is established on the basis of k/N system of multi-component,then the operational availability and cost per time in the model are also analyzed.Finally,several examples are given to verify that this Petri nets model can analyze the effect of spares amount in grass-roots level and base level and the maintenance strategy′s parameter(m,NG) for the system′s support effectiveness,which is more practical and overcomes the limitations of analytical model. |
