Abstract

To prevent defective products or accidents due to human error, it is essential to apply error proofing solutions before hands. However, estimation of the occurrence rate of each error depends on the qualitative judgment of operators in charge, with the method for qualitatively estimating the rate based on objective data not being studied well except a few previous researches. This paper focused on machining typically adopted in manufacturing and proposed a method of qualitatively estimating human error occurrence rates for a wide range of operations. In this method, work elements included in the operations are identified and the error occurrence factors are scored for each work element, and then the error occurrence rates are estimated based on the formulas between error occurrence factors and error occurrence rates, which have been produced in advance. This method was applied to two machining processes. As the results, it was found that error occurrence rates can be estimated precisely using a small number of error occurrence factors, different formulas should be used depend on type of error, and as for a certain type of error, stratification by type of work element is needed.
