[0001] 本申请公开了一种面向无人机网络的级联失效模型构建方法、设备、介质及产品，涉及无人机网络技术领域，该方法包括构建机载平台层模型、数据网络层模型及智能协调层模型；基于三者构建跨层依赖级联传播机制，其至少包括跨层耦合模型和跨层传播动力学模型；以系统初始状态和初始故障集合为输入，在每个离散时刻，利用各层模型更新对应层的状态及健康度变量，根据耦合矩阵更新层间影响，结合阈值规则判定无人机是否失效；若失效，基于跨层传播动力学模型并依据耦合矩阵更新其他功能层的退化状态，直至级联失效停止，输出演化结果。本申请从三个维度进行多源扰动建模，实现多层功能耦合及异常跨层传递的建模，提高了级联失效分析的准确性与适用性。
