摘要
对生产线顺序拉动下的零部件拣选配送区的分区拣选问题作出研究。在SPS配送模式下,为实现分区拣选时间均衡及与生产节拍相一致这2个目标,建立含有生产节拍的数学模型,通过寻找每区的最佳储位数,最小化目标函数,进而得出最优分区数目。提出启发式算法对各零部件拣选频率优化排序,找到频率储位分配原则,以此化简模型。通过算例研究,令生产节拍分别在160 s及80 s时,结果显示各分区拣选时间均衡,并与生产节拍相一致。这样,随着生产线生产节拍的变化可以灵活改变拣选区数目,亦即拣选人员数目,可为决策者实现拣选作业现场的少人化提供决策理论依据,减少拣选费用。
A research is conducted on the zoning problem of part distribution picking area for assembly lines with pull production. In such a set parts supply （SPS） distribution mode, to balance the picking time of each zone and identify production tact （TT）, a mathematical model containing TT is established. By solving this problem to minimize the objective function, the optimal number of zones is obtained. Then, a heuristic algorithm is put forward. It optimizes the part picking frequency and sequence. By this method, it presents a rule to determine the location distribution. At last, an exemplary research is made. For this example, when TT is 160 s and 80 s, the result shows that the above two objectives are realized in reasonable error. Thus, with the changing posed method provides a theoretical picking cost. of TT, one can flexibly change the number of picking zones. The proreference for decision-makers to realize shojinka in job site and reduce
