Abstract: To improve the situation that the constituted standard time could not require employees strictly,which led to low efficiency due to ignoring human factors,a standard time development method based on staff's work enthusiasm level index was proposed.The range and meaning of each work enthusiasm level was defined.According to the law that skilled employees working hours data comply with normal distribution,the enthusiasm level index model was built based on skewness coefficient.Observation time was revised by enthusiasm level index,skilled coefficient and allowance coefficient,and the standard time was established.In addition,the definition rationality,value rationality and technique rationality of work enthusiasm level index were used as the theory basis for proposed method's correctness.The rationality and feasibility of this method was verified by the example of standard time of each process in inner cylinder assembly line of A company.

Key words: standard time, assessment index, work enthusiasm level index, skewness coefficient
