然后在可靠性框图分析的基础上,依据判定表,自动生成故障树。
Then based on the reliability block diagrams and decision table, we construct the fault tree for multistate system.
可靠性模型是指为预计或估算产品的可靠性所建立的可靠性框图和数学模型。
Reliability models are reliability block diagram and mathematics models that built to predict and evaluate reliability of products.
常规的系统可靠性分析方法有故障树法、失效模式与影响分析法和可靠性框图法等。
Fault Tree analysis, Fault Modes and Effects analysis and Reliability Block Diagram are the popular methods for the system analysis.
