The two - stage modeling method for software project risk ’ s static bayesian networks is studied . the object - oriented modeling method for risk bayesian network is presented , structure refinement method based on network measurement is discussed , and probability parameters refinement method based on maximum likelihood estimates is put forward 為提高風(fēng)險(xiǎn)模型的準(zhǔn)確性,提出了基于網(wǎng)絡(luò)度量的風(fēng)險(xiǎn)貝葉斯網(wǎng)絡(luò)結(jié)構(gòu)改進(jìn)算法,給出了基于極大似然估計(jì)的風(fēng)險(xiǎn)貝葉斯網(wǎng)絡(luò)概率參數(shù)更新算法。
