【摘要】 对故障树进行逻辑简化将有效提高分析计算的速度。根据故障树结构特点,提出了基于贪心算法的故障树逻辑简化方法。该方法已编程实现,并采用实际系统的故障树进行了测试。实践证明,该方法可大幅度提高分析求解速度,同时,该方法所采取的贪心策略又可运用在故障树分析的其他方面。更多还原

【Abstract】 Logical reduction can speed up fault tree analysis effectively.A fault tree(logical) reduction strategy based on greedy algorithm is presented.The strategy was(implement)ed and tested by analyzing practical system fault trees.Facts prove that the strategy can speed up fault tree analysis greatly,meanwhile,the greedy thinking of the strategy can be applied to other aspects of fault tree analysis.更多还原
