摘要:
针对协同设计过程中的数据一致性问题,分析了已有的并发冲突避免策略,结合CATIA的特殊性提出了一套可变粒度锁的冲突避免策略,设计了总体框架及核心算法.以节点间关联性作为判断依据进行节点仲裁选择,并提出节点关联集的维护算法.在协同设计平台中,利用XML实现并发控制机制,对提出的算法进行了实验,验证了用户可互斥地访问对象,并保证一致性.
Abstract:
A im ing at the prob lem of data consistency in collaborative des ign, the pape r analyzes the ava ilab le strateg ies o f subsequent co llision avo idance, puts fo rw ard one co llision avo idance stra tegy of a lterab le g ranu larity lock by com bining w ith the particu larity of CATIA. It designs the g lobal frame and kerne l a lgo rithm. It adopts re levancy of nodes as the dec id ing cr iterion to arb itrate and choose nodes, and puts fo rw ard the a lgor ithm of ma in tain ing node relevant aggreg ation. In the co llaborativ e design platfo rm, XML is used to carry out the subsequent contro l mechan ism, and the propo sed algorithm. The exper iment indicates tha t user can access m ode l resourcem utua lly exc lusive ly and ensure the consistency
