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的分布式系統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中間件的體系結構以及其要解決的關鍵問題。
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的產生、發展及其在國內外的研究應用情況;接著分析了并行工程技術應用過程中產生的問題,提出了基于并行工程的產品開發系統應具有五個子系統: cad系統平臺、設計任務動態分配系統、沖突協凋系統、通信系統和pdm系統。
