摘要: 拆卸序列的紧凑表示是拆卸序列的评价与优化的基础,AND-OR图是拆卸序列表示的一种典型方法,但是拆卸序列的AND-OR图表示模型存在冗余信息。通过对AND-OR图模型作等价变换,消除AND-OR图表示模型中的冗余信息。设计了拆卸序列的优化表示模型的生成算法,建立了优化的基于OBDD的拆卸序列表示模型,用来表示复杂装配体的拆卸序列。并论证了优化模型的拆卸序列表示可以节省存储空间,最后的实验表明,基于OBDD的拆卸序列优化表示模型的存储空间远小于AND-OR图的存储空间。

Abstract: Representation of disassembly sequence is the basis of evaluating andoptimizing it and AND-OR graph, a typical method for representing sequences, has redundancy in representing information of disassembly. Through equivalent transformation of AND-OR graph, such redundancy is eliminated. Furthermore, generating algorithm of optimized representing model for disassembly sequence is designed and such model based on OBDD is established to represent disassembly sequence of complex assembly. Final experiment shows that memory space of optimized representation model based on OBDD is much less than that of AND-OR graph. 
