利用随机组合群验理论建立了数控机床人因可靠性评价数学模型,依据这一模型对数控机床人为差错做定量分析,筛选出人因可靠性差的操作工人.
Based on stochastic group theory, a mathematical model of human factors reliability evaluation of CNC machine tools was established. Based on this model, quantitative analysis of human error of CNC machine tools was made, and the operatives with poor human reliability were screened out.
