摘要:
針對目前飛機測試性指標論證時(shí)缺乏有效方法支撐問(wèn)題,提出了一種基于廣義隨機Petri網(wǎng)(Generalized Stochastic Petri Nets,GSPN)的測試性指標確定方法;通過(guò)分析飛機航線(xiàn)級的維修過(guò)程,構建過(guò)程的GSPN模型,并對模型進(jìn)行求解和分析,得到測試性指標與使用可用度和平均修復時(shí)間之間的關(guān)系,以這兩個(gè)指標共同作為約束目標,通過(guò)權衡分析確定飛機合理的測試性指標,并以某飛機測試性指標論證為例,演示驗證了方法的可行性。
Abstract:
Aiming at the problem of lacking of effective method in the determination of aircraft testability index,a new method is proposed based on Generalized Stochastic Petri Nets. Through analyzing the maintenance process of the aircraft line level,the GSPN model of the process is constructed. Then the model is solved and analyzed. Meantime the relationship between testability index and operational availability and mean time to repair is also obtained. Using the two indexes as a constraint,rational testability index is determined by trade-off analysis. Finally,taking the determination of one aircraft testability index as an example,the feasibility of the method is demonstrated.
