为了提高包装产品协同设计过程中历史多版本的查询效率,针对完整版本和增量结合的树形结构多版本演化模型,设计并实现了一种以版本间距离程度为度量依据的中间完整基版本选择算法。 实验表明,通过该算法选择的增量还原基版本,使多版本还原效率进一步提高;同时,该算法有使用简单、无复杂控制参数、版本树数据冗余易于控制等特点。

In order to improve the efficiency of versions inquiring in packaging product collaborative design process , an algorithm for selecting base version by distances between reiated versions, was designed and implemented. This algorithm is of versions tree structure. Experiments showed that the version distribution model determined by the algorithm has better performance. The efficiency of regenerating all the versions is improved. The algorithm without complex control parameters is simple to use, and the data redundancy of versions is easy to control.
