墨菲定律变体之一:“如果几件事都可能出错,首先出错的往往是会造成最大损失的那一件。”如果一个系统可能产生直接或间接的致命威胁,例如,机器故障等,那么设计该系统时,必须最大程度地降低故障可能性及其导致的负面影响。为了确保发生随机性和确定性故障的概率尽可能低,必须遵循特定的设计方法。工业中将这种设计方法称为功能安全方法。这种方法要求对系统进行细致入微的分析,确定所有潜在的危险情况,并运用极佳做法来将 One of Murphy’s Law Variants: “If something goes wrong, the first thing that goes wrong is often the one that caused the most damage.” "If a system can have a direct or indirect fatal threat, such as a machine failure Etc., then the system must be designed to minimize the likelihood of failure and the consequent negative effects. In order to ensure that the probability of occurrence of randomness and deterministic failure is as low as possible, certain design methods must be followed. This design method is called functional safety method in industry. This approach requires a detailed nuanced analysis of the system, identifying all potentially dangerous situations and applying best practices to
