蚂蚁算法在面向零件的网络化制造中的应用研究

Research and application of ant algorithm in networked manufacturing for parts

为了有效地实现网络制造环境下资源共享与优化配置,提出了协同制造链的概念,指出协同制造链是一种围绕零件制造过程的网络化制造动态联盟。在此基础上给出了协同制造链的定义和形式化描述,并以某航空发动机关键零件为具体应用研究对象,详细分析了协同制造链的构建和演化过程;同时,对协同制造链构建和演化过程中的关键问题——协同制造链排序进行了重点研究,建立了该问题的数学描述模型,设计并实现了一个基于蚂蚁算法的协同制造链排序策略。最后通过实例验证了该策略的有效性。

To optimize the configuration of distributed manufacturing resources in the networked manufacturing environment effectively, this paper introduced a concept of the collaborative manufacturing chain, The collaborative manufacturing chain was a kind of networked manufacturing dynamic alliance which oriented to the manufacturing process of parts. Based on it, gave the definition and the formalized model of the collaborative manufacturing chain, By analyzing the distributed manufacturing process of aero-engine complex parts, expatiated the evolution process of the collaborative manufacturing chain. Then, studied the sequencing problem of the Collaborative manufacturing chain emphatically, which was a key problem in the evolution process of the collaborative manufacturing chain, built the mathematical model of this problem, and designed and implemented a sequencing strategy of the collaborative manufacturing chain based on the ant algorithm. Finally, demonstrated the validity of the strategy by an example.
