The solution used for merging real - time and fault - tolerance in dynamic distributed system was found out , the architecture for the rt - ft middleware based on corba was proposed , and related key problems required to solve are mentioned 從理論上探索了在動態(tài)的分布式系統(tǒng)中融合實時與容錯的方案,并提出了具有實時?容錯性能的corba中間件的體系結(jié)構(gòu)以及其要解決的關(guān)鍵問題。
Concurrent engineering is increasing well - rounded advanced manufacture technique . in the first section , firstly produces the engender , development and applications of the concurrent engineering in the world ; secondly analyses the application problems of concurrent engineering ; lastly puts forward that the product empolder system based on concurrent engineering includescad system , design assignment dynamic distribute system , conflict correspond system , communicate system and product data management system 本文首先介紹了并行工程技術(shù)的產(chǎn)生、發(fā)展及其在國內(nèi)外的研究應(yīng)用情況;接著分析了并行工程技術(shù)應(yīng)用過程中產(chǎn)生的問題,提出了基于并行工程的產(chǎn)品開發(fā)系統(tǒng)應(yīng)具有五個子系統(tǒng): cad系統(tǒng)平臺、設(shè)計任務(wù)動態(tài)分配系統(tǒng)、沖突協(xié)凋系統(tǒng)、通信系統(tǒng)和pdm系統(tǒng)。
