Measure OHS performance using statistical tools

الملخص EN

Now quality is being for all firms a new strategic which led to extremely installation of severe control methods; manufacturers are forwarded to increasingly strong and consequently very expensive constraints.

the systematic use of Gaussian distribution in random phenomena modeling has been largely contributed to this overflow and can be unsure whether the matter requirements of capability do not show the way to production capability means.

in the same way manufacture follow-up by control chart generates lose of time and are not justified (duration, frequency, control quality).

when certain conditions are met production monitoring can be brought back to a problem of systematic preventive maintenance.

our research is dealing with resolving matter of capability in the case of no normal distribution and to compare index of capability in both situation normal and no normal for control chart in production problem.
