Based on the stable reliability design theory and the optimization design method,  the stable reliability-based optimization of compressive bar is extensively discussed and a numerical method for stable reliability-based optimization is proposed.  On the condition of known first two moments of basic random variables,  the respective program can be used to obtain the stable reliability-based optimization information of compressive bar accurately and quickly.
