Based on relevant design theory and optimization method, the stability and reliability optimization of arbitrarily-distributed parameters is postulated for compression bars. Assumed that the first four moments of basic random variables are known, the accurate optimization information can be efficiently obtained using computer programs. Therefore, this method has proven its effectiveness and practicality via numerical illustrations.
