秒表时间研究法在装配线工时测定中的应用

The Application of Direct Time Study-Intensive Samplings in the Determination of Working Hours for the Assembly Line

实地调研研究对象装配现场,对其装配流程采用秒表时间研究法进行测时。首先预观测,运用三倍标准差法对预测时数据剔除异常值,将合格数据代入观测次数计算公式,得出正式观测所需的次数,进行正式测时与数据分析,计算该装配线当前的平衡率。

Field research on the assembly site of the research object, the assembly process is measured by Direct Time Study-Intensive Samplings. First, the pre-observation, three standard deviation method is used to eliminate outliers in the forecast data, the qualified data is substituted into the formula for calculating the number of observations, the number of formal observations required are made, Formal test and data analysis are began, and calculate the current balance rate of the assembly line.
