Abstract

This research is concerned to develop a software that can be used to solve the reliability problem. A reliability is concerned with random accuracies of undesirable events, or failures during the life of a physical system. In order to fulfill the objective of this research, we have used the Least-squared method and Matlab software as a tool to solve the problem. The data that we have collected from semiconductor company shown that they produce diode in range 1000000 to 1500000 units per day. Based on our observations, we found that about 0.2551 % units are rejected. Based on our developed software we can forecast or estimate the number of unreject and reject items.
