1、基于并行工程的產(chǎn)品開(kāi)發(fā)過(guò)程規(guī)劃方法研究摘要在當(dāng)前競(jìng)爭(zhēng)激烈需求變化非常迅速的市場(chǎng)環(huán)境下，企業(yè)要取得成功，必須采用先進(jìn)的開(kāi)發(fā)模式來(lái)提高產(chǎn)品的開(kāi)發(fā)周期、質(zhì)量、開(kāi)發(fā)成本及客戶(hù)服務(wù)水平，以此來(lái)提升企業(yè)的競(jìng)爭(zhēng)力。隨著現(xiàn)代產(chǎn)品復(fù)雜程度的提高，產(chǎn)品開(kāi)發(fā)過(guò)程管理和規(guī)劃的難度也越來(lái)越大。為了加強(qiáng)產(chǎn)品開(kāi)發(fā)人員之間的交流和協(xié)作，并對(duì)產(chǎn)品開(kāi)發(fā)過(guò)程進(jìn)行合理的規(guī)劃和改進(jìn)，建立能夠準(zhǔn)確地描述和分析產(chǎn)品開(kāi)發(fā)過(guò)程及活動(dòng)間信息關(guān)系的產(chǎn)品開(kāi)發(fā)過(guò)程模型已成為成功實(shí)現(xiàn)產(chǎn)品開(kāi)發(fā)的重要手段。為了解決產(chǎn)品開(kāi)發(fā)過(guò)程中引入并行工程而導(dǎo)致開(kāi)發(fā)過(guò)程復(fù)雜，難以高效執(zhí)行的問(wèn)題，本文通過(guò)研究分析并行工程下任務(wù)間的信息關(guān)系，提出了基于任務(wù)間耦合信息
