利用混合图对模块化拆卸进行建模的研究

Researches about Modeling Hybrid Graph Model with Modularize Disassembly

拆卸序列规划是面向拆卸回收设计研究的重点之一,生成有效可行的拆卸序列是问题的关键,而序列的生成又与拆卸模型的建立密切相关。产品拆卸模型主要有基于图论的无向图、有向图、与或图和Petri网。在传统的拆卸序列规划过程中,随着产品零件数目的增加,会造成组合爆炸问题。为解决该问题,提出了一种利用混合图对模块化拆卸的建模方法。这种方法,既吸收了混合图的观点,又渗透合并了模块化的思想。最终通过一个实例验证了该方法的有效性和合理性。

Disassembly sequence planning is one of the important researches of DFD, creating feasible and effective disassembly sequence is the key problem. Disassembly sequence has a close relation with disassembly model. Disassembly model of product is mainly established through some graph concepts in graphic theory. During the conventional process of disassembly sequence planning, with the increase of the number of parts, disassembly sequence may explode exponentially. To solve this problem, a new method for disassembly hybrid graph model based on modular design is proposed. This method not only includes the concepts of hybrid graph, but also has the thought of modular design. Finally, an example is also given to show that this method is feasible and effective.
