بررسی خطاهای انسانی دراتاق کنترل دستگاه انکویلر شرکت لوله سازی اهوازبااستفاده از روشهای SHERPA و HET در سال 1390

  Background and Aims : industrial development and application of new methods to improve production resulted human errors to be considered more seriously. With this intention, the use of human error identification techniques followed by application of remedy to analysis human errors and decrease of their occurrence probability and criticality became main discussion of scientific and industrial meetings. In addition it can be noticed that by different techniques, human error identification, evaluation and control are performed by better precision and this three-step process is the purpose of this study.     Methods: In this descriptive epidemiological study by using both methods of SHERPA and HET human errors has been detected in the Ancoiler device control room of number 3 factory of Ahwaz Pipe Mill . This study is conducted with the application of two techniques in order to obtain two viewpoints for human error identification.
