| Abstract: | Firstly knowledge about ALT optimal design is studied and constant stress ALT of product with competing failure is chosen for application. Secondly statistical analysis of ALT is examined and then optimal goal function is set up through analysis of test plan factors and constraints. A new optimal method is brought up based on simulated annealing （SA） and realization method is given. Lastly this new method is proved to be practicable and applicable by an example. |
