The layout of a two stage process consists of a single lathe(L1) at stage1, two welding machines in parallel (W1 and W2) at stage 2, and a buffer B1 between. Stages 1 and 2. The processing times. Are. L1:3 min, W1:5 min and W2:6 min
1.What is closes to the CT for stage 2? (5:45 min. means 5 minutes and 45 seconds)
2.What is the hourly system capacity?
3.What is the minimum MLT for the system?
4. From the above system, jobs are released to L1 to maximize the production. You should finish the following Gantt chart to minimize WIP. (the first job was given) jobs are number 1,2,3,4 and so on.
