Abstract: Based on the reliability design theory and the robust design method,the reliability-based robust design of compressive bar under incomplete probability information was extensively discussed,and a numerical method for stable reliability-based robust design was proposed.The reliability sensitivity was added to the reliability-based optimization design model,while the stable reliability-based robust design was described as a multi-objection optimization.If first four moments of basic random variables have already been known,the computer program can be used to obtain accurately and quickly the stable reliability-based robust design information of compressive bar under incomplete probability information.
