摘要

我们对风险矩阵（RM）的数学和工程科学基础进行了回顾。目的是查找和评估有关其使用的信息。风险矩阵受数论、集合论、计量学和函数分析的制约，这解释了其使用的优势和劣势。尽管有错误的报道，但序数乘法硬性规定了单元格的数字分配。虽然引入了一个缩减，但没有找到改变序数等级的科学依据。现有证据表明，RM 不可靠。举例说明。提供了有益使用 RM 的建议。

Retrospective on the risk matrix, part II: Mathematics

We present a review of mathematical and engineering science foundation of the risk matrix (RM). The objective was to locate and evaluate information surrounding its use. RM is governed by number theory, set theory, metrology, and functional analysis, which explains the strengths and weakness of its use. Although incorrectly reported, ordinal multiplication rigidly sets the cell numeric allocation. No scientific support was found for changing the ordinal ranks, although one reduction is introduced. Existing evidence suggests that the RM is unreliable. An example is given. Suggestions for beneficial use of the RM are provided.

期刊介绍： Process Safety Progress covers process safety for engineering professionals. It addresses such topics as incident investigations/case histories, hazardous chemicals management, hazardous leaks prevention, risk assessment, process hazards evaluation, industrial hygiene, fire and explosion analysis, preventive maintenance, vapor cloud dispersion, and regulatory compliance, training, education, and other areas in process safety and loss prevention, including emerging concerns like plant and/or process security. Papers from the annual Loss Prevention Symposium and other AIChE safety conferences are automatically considered for publication, but unsolicited papers, particularly those addressing process safety issues in emerging technologies and industries are encouraged and evaluated equally.
