Choosing appropriate distribution yb minitay’s 17 software to analysis system reliability

الملخص EN

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 theprogram.

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.
