在石油天然氣，石油煉制，石油化工等領(lǐng)域，利用VMGSim你能夠
準(zhǔn)確建模并預(yù)測(cè)大多數(shù)的工藝裝置的性能；
VMGSim在提高模擬模型的使用和開(kāi)發(fā)效率方面有了新的創(chuàng)新：
集成了wq交互式流程模擬的{zx1}技術(shù)；
工業(yè)級(jí)強(qiáng)大的熱力學(xué)物性數(shù)據(jù)庫(kù)和物性計(jì)算；
使用Visio, 窗體，腳本或網(wǎng)絡(luò)瀏覽器進(jìn)行圖形化建模；
將大家所熟悉的Excel 作為一個(gè)單元操作或計(jì)算器而無(wú)縫嵌入
到你的VMGSim模型中；
模擬引擎：
在流程模擬單元，純組分以及循環(huán)物流中，即便對(duì)于{zd0}規(guī)模的模
型，VMGSim 都能夠毫無(wú)限制地進(jìn)行求解；你可以創(chuàng)建工藝模型，
并將模型存儲(chǔ)為單元模板，以便在新的流程模型中進(jìn)行調(diào)用；
VMGSim 的子流程架構(gòu)允許你在任何嵌套次數(shù)的工藝流程方案中，
將模板以子流程的形式嵌入；
VMGSim 先進(jìn)的高級(jí)計(jì)算技術(shù)是確保成功模擬你的工藝過(guò)程的理想
工具；VMGSim可以使你的模型簡(jiǎn)化: 它不再使用熱循環(huán)流，也沒(méi)有
必要在過(guò)程模型中包含不真實(shí)的物流，這是由于VMGSim在流程引
擎設(shè)計(jì)時(shí)采用了獨(dú)特的端到端物流連接技術(shù); VMGSim 可以在模型
中自動(dòng)進(jìn)行任何循環(huán)物流的計(jì)算，而不需要用戶的干預(yù)；
與電子表格軟件產(chǎn)品相近，用戶輸入VMGSim的任何信息都會(huì)被立
即處理；因此,模型的建立和優(yōu)化同樣迅速{gx}；
