Development of New Method for Product Reliability Prediction Base on Bayesian Approach Mahtab Jahanbani fard m jahanbanifard@in iut ac ir Date of Submission 2010 04 19 Department of Industrial and System Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisor Ali Zeinal Hamadani hamadani@cc iut ac ir Abstract This thesis presents a new model for predicting product s reliability early after its production and introducing to the market It is assumed that time to failure of this product has Weibull distribution Also we assume that shape parameter of this distribution is known The scale parameter is a random variable that could have different distributions Bayesian statistics are used to join prior information on past product failure and sparse few field data on current product s performance The Bayesian model provides a more accurate and logical prediction compared to classical methods and indications are favorable regarding the model s practicality in industry applications This model has managerial usefulness because of having an accurate prediction Keywords Reliability prediction Bayesian theory Weibull distribution Prior information
