The main procedure and steps are following as : according the random characteristic of the time spent by each work procedure , computer simulation is applied to produce the most possible scheduling network . and by corresponding optimization and adjustment on the network , the cost and scheduling construction network can be obtained ; during the practical construction according to the network , the warp between the actual cost and expected scheduling is tracked dynamically . then the computer simulation system is used to predict the future cost and progress operation , and take corresponding precautionary measures to control beforehand 其主要思想與步驟為:首先運用計算機仿真技術(shù)來仿真工序作業(yè)時間的隨機特性,產(chǎn)生概率最大的施工網(wǎng)絡計劃,并對其進行優(yōu)化和調(diào)整,以獲得滿足工期、質(zhì)量要求的成本及網(wǎng)絡計劃;在施工過程中動態(tài)跟蹤施工實際成本與進度與目標計劃所發(fā)生的偏差以及質(zhì)量問題,然后根據(jù)已出現(xiàn)的偏差,利用計算機仿真技術(shù)對項目未實施部分進行進度、成本的預測和分析,根據(jù)現(xiàn)有信息對網(wǎng)絡計劃未完成部分進行調(diào)整和優(yōu)化,以盡可能把各項費用控制在預定計劃成本之內(nèi)或使工程的綜合指標最優(yōu)。
