摘　　要：为增强协同设计过程中多版本数据存储的可靠性、提高多版本查询检索效率,在多版本树存储机制的基础上,考虑版本间变化的差异性,提出一种利用版本间相似系数和确定中间版本存储模式的算法。实验结果证明,该算法可使数据冗余变得可控,与同类算法相比,版本恢复效率更高,版本树整体性能更优。In order to enhance the reliability of multi-version data storage and improve retrieval efficiency of versions in collaborative design process,by considering unbalanced difference between versions,this paper proposes an algorithm using similar coefficient sum to determine the storage model of multi-version suitable for version tree.Experimental results prove that data redundancy of multi-version storage model calculated by the algorithm proposed becomes controllable,as the time spent regenerating all of the versions is reduced and the performance of multi-version tree is improved.
