In the system , dss integrates relative kb together , especially the train routing kb , approval experience kb . at the same time , the paper constructs the relative model of the claimed train approval optimization model in railroad bureau and uses the minimal cost and maximal flow algorithm based on queueing theory to solve the problem 在本系統(tǒng)中, dss中集成了相關(guān)的知識(shí)庫(kù)系統(tǒng),特別是車流徑路知識(shí)庫(kù)、審批經(jīng)驗(yàn)知識(shí)庫(kù)。同時(shí),對(duì)鐵路請(qǐng)求車審批優(yōu)化中的請(qǐng)求車審批優(yōu)化問(wèn)題建立了相應(yīng)的模型,并利用基于排隊(duì)論的最小費(fèi)用最大流求解了該問(wèn)題。
