Reliability for Weibull Distribution using Ms-Excel

The weibull distribution is mostly used in reliability analysis life data due to its versatility. Depending on the values of parameters, can be model a variety behaviors. three parameter estimate probability null wind speed and gives greater weight low speeds. We also discuss least square method estimation problems hypothesis testing issues, with emphasis graphical methods some software are provided. applicable design stage in-service time as well it not only limited production stage. Now, techniques perform Weibull process done by statistical programs.
