摘要:

因大量采用分布式、综合化、模块化方案, 复杂电子系统极易出现共因故障和故障并发等新问题, 传统测试性参数确定方法难以解决。针对这一问题, 提出一种基于着色广义随机Petri网(colored generalized stochastic Petri nets, CGSPN)的复杂电子系统测试性参数确定新方法。首先, 综合需求信息、约束边界和维修保障等要求, 建立电子系统两层级CGSPN模型, 引入着色,实现不同模块各种状态的实时追踪和故障并发处理, 通过广义随机处理共因故障的随机不确定性;然后, 利用着色和可用度探索一种带有冗余设计的测试性参数处理手段, 丰富测试性体系;最后, 构建一种不同模块、各种状态融合的并行分析技术, 统一系统层和模块层之间的状态转移关系, 避免分阶段串行处理和等效替换。以通信导航识别系统为例进行实例分析, 所提方法比传统方法具有更好的可用性和有效性。

Abstract:

Due to the extensive use of distributed, integrated, and modular solutions, complex electronic systems are prone to new issues such as common-cause failures and fault concurrency, which are difficult to address using traditional methods for determining testability parameters. To address the above issue, a novel method for determining testability parameters for complex electronic systems based on colored generalized stochastic Petri nets (CGSPN) is proposed. Firstly, by incorporating requirements such as demand information, constraint boundaries, and maintenance support, a two-level CGSPN model for electronic systems is established. Coloring is introduced to enable real-time tracking of various states of different modules and to handle fault concurrency, while generalized stochastic processing addresses the randomness of common-cause failures.Secondly, a testability parameter processing method incorporating redundancy design is explored through coloring and availability, which enriches the testability system. Finally, a parallel analysis technique integrating different modules and various states is developed, unifying the state transition relationships between system and module levels, and avoiding stage-wise serial processing and equivalent replacement. An example analysis of communication navigation identification (CNI) system demonstrates that the proposed method offers better usability and effectiveness compared to traditional approaches.
