摘要
针对离散生产线加工过程复杂,在制品堆积较多、等待及加工总时间较长的问题,创造性的提出运用排队论来具体分析解决。首先分析产线在制品堆积问题,应用排队论建立在制品排队等待模型,然后根据实际生产状况改进现有排队模型,确定最大在制品规模。同时综合运用动态规划方法与均衡化生产方式,建立动态规划模型,确定不同品种产品加工顺序,并提出最佳改善方案,最终达到提高设备利用率,减少加工总时间,实现精益生产的目的。现场实施表明,排队论在离散问题的解决中发挥重要的作用,为离散制造在制品改善提供了重要的依据。
According to the complexity of discrete production line process, more WIP, longer total time pro-cessing, creative proposed the use of queuing theory to solve the specific analysis. First analysis of production line of work in process accumulation, application of queuing theory to establish the WIP queuing model and according to the actual production condition improved existing queuing model to determine the largest WIP. Then comprehensive using the dynamic programming method and balanced production, dynamic programming model is established, determine the different varieties of products processing sequence, and the best improvement scheme is put forward, and ultimately to improve equipment utilization rate, reduce the total processing time,achieve the purpose of lean production. Site implementation shows that queuing theory plays an important role in the solution of the discrete problem, and provides an important basis for discrete manufac-turing WIP improvement.
