Abstract

This research aims to choose the appropriate  probability ‎ distribution  ‎‏‎ to the reliability‎        analysis‎ for  an   item through ‎ collected data for operating and stoppage  time of  the case  study.

    Appropriate choice for .probability distribution   is when  the data look to be on or  close the form fitting line for probability plot and test the data  for  goodness of fit .

     Minitab’s 17 software  was used ‎  for this  purpose after  arranging collected data and setting it in the the program‎.

     The program results gave the‎ best or well-fitting distribution among four of default probability distributions, that will use in order to estimate the distribution parameters values,‎ for reliability determination and analysis. From probability plot can estimate time that designates the percent of the item's failure.
