生产调度工作总结

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①确定工艺流程1)工艺流程：4H发动机：4H Testing 4H Painting 4H Eviromental WareInventaryDCi发动机：DCi Painting Subline 1/4 DCi Assembly line DCiTesting Subline DCi Enviromental Ware Inventary2)流程路线：4H发动机：4H Testing Testing Subline 4H Painting Buffer 4HPainting 4H Eviromental Buffer 4H Eviromental Subline Inventary(用表示)DCi发动机：DCi Painting Subline 1/4 DCi Assembly line DCiTesting Subline DCi Enviromental Subline Inventary(用表示)②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。

③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。

（2010-6-28～2010-7-4）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。
