生产调度工作总结.doc

工作日志题目：基于Flexsim车间混流生产线的仿真建模与研究(一) 项目介绍 基于Flexsim，对东风二汽发动机厂DCI 11和4H两条生产线进行模拟仿真，找出影响生产效率的因素，得出最佳的解决方案。(二) 问题来源公司生产计划编排都是采用人工编译作业，无法找出影响生产效率的关键因素，效率低，任务量大，没有找到一条科学的生产计划编排方法，很多都是一些事后补救工作。(三) 要达到的目的运用Flexsim 仿真软件对两条生产线进行模拟，观察是否存在堵塞、闲置等现象，找出影响生产效率的关键瓶颈，提出改进方法。(四) 解决的具体步骤 确定工艺流程1) 工艺流程：4H发动机：4H Testing 4H Painting 4H Eviromental Ware Inventary DCi发动机：DCi Painting Subline 1/4 DCi Assembly line DCi Testing Subline DCi Enviromental Ware Inventary2) 流程路线：4H发动机：4H Testing Testing Subline 4H Painting Buffer 4H Painting 4H Eviromental Buffer 4H Eviromental Subline Inventary(用 表示) DCi发动机：DCi Painting Subline 1/4 DCi Assembly line DCi Testing Subline DCi Enviromental Subline Inventary(用 表示) 将车间布局的CAD图导入到Flexsim中，设定比例后，导入进去的CAD图形尺寸大小在Flexsim中一方格代表1米，通过CAD图形的导入，每台机器的位置，即可确定。 添加实体，确定各个子车间的加工流程和各辆小车的运输路径。（2010-6-282010-7-4）几点说明： 对于DCI11预装和拆预装的工艺流程还没确定，4H没有预装和拆预装） DCI 11预装与拆预装的时间为3.75分钟/台。 两种产品（DCI 11 和 4H）有预装上的差异，上下线点没有差异 4H 从装配线下线点到待试验区缓冲区的距离为174.2m。 传送带的速度设为1m/s。 检测器的预置时间为10秒，输送机暂存区的容量为10。 叉车只能沿着规定的路线行驶。 DCI 11 1/4 小车的规格 137213304H 1/4 小车的规格 1220930 到达检测车间的时间服从均值20，方差为2的正态分布 到达检测车间的产品类别（1,2,3）服从均匀分布 对于整个物流过程，应加入看板管理 基于生产计划，针对各个子车间，加入投产序列1）实现方法应用合成器，加入全局表，即可保证指定的投产序列2）具体实现方法n 油漆线和测试线的任务序列 PaintOrderitem1item2StarttimeRow11017.50Row21025.00Row31032.50Row41040.00Row51047.00Row60151.25Row71055.00Row 80158.75Row90168.25Row100172.00 TestOrderitem1item2StarttimeRow10125.00Row21028.75Row31040.00Row40143.75Row50147.50Row61051.25Row70155.00Row 81059.75Row91063.50Row101067.25n 油漆线和测试线的到达序列及其合成器的编译代码1）Painting: Arrival Schedule : ArrivalTimeItemNameItemTypeQuantityPaintLbleArrival117.50Product1.001.001.00Arrival225.00Product2.001.001.00Arrival332.50Product3.001.001.00Arrival440.00Product4.001.001.00Arrival547.00Product5.001.001.00Arrival651.25Product6.001.001.00Arrival755.00Product7.001.001.00Arrival858.75Product8.001.001.00Arrival968.25Product9.001.001.00Arrival1072.00Product10.001.001.00 Combiner / Process Time : Return constant time of 0. / Combiner : Batch / Send To Port : treenode item = parnode(1);treenode current = ownerobject(c);/*Conditional Port*/* nIf some condition is true (equal to 1), send to a given port.
