摘要: 针对直线布局轨道式智能加工系统单自动引导车(rail guide vehicle, RGV)单工序作业调度进行研究。考虑到智能RGV与数控机床(CNC machine tools)的特点,建立了给定时间内RGV与CNC机床配合物料加工下料用时之和最小化为目标的非线性整数规划模型。当加工物料数目比较多时,求解该问题非常耗时。根据RGV与CNC机床加工物料调度特征,提出计算机模拟仿真算法对问题进行求解。利用3组系统参数对模型及算法的有效性和实用性进行了检验分析,最后给出了最优调度计划的实际运行结果及结论。

Abstract: Single process scheduling with single rail guide vehicle (RGV) in linear layout intelligent machining system is studied. Considering the scheduling characteristics among RGV and CNC machine tools, a non-linear integer programming model is proposed to minimize the total time of unloading products in a given period. When the number of processed materials is relatively large, solving this problem takes far too long time. According to the scheduling characteristics among RGV and CNC machine tools, a computer simulation algorithm to solve the problem is established. In order to verify the effectiveness of the algorithm, three sets of system parameters are used to verify the practicability and effectiveness of the model, and the actual operation results and the optimal scheduling are given.

Key words: intelligent rail guide vehicle, CNC machine tools, computer simulation
