Case II

In Case II, you assume there are two operators (Operator 1 and Operator 2). Operator 1 handles workstation 1 and 2 and operator 2 handles workstation 3 and 4 2. Workstation 2 and Workstation 3 has one oven each. There are two auto times, one at workstation 2, proof dough (5 sec) and other one at workstation 3, bake in oven (10 sec). 4. Following assumptions are made: a. Available time after breaks per day is 300 minutes, takt time is 25 seconds.

Questions:

1. Is operator a bottleneck? (Build a Yamizumi chart to support your answer. How can you reorganize your work elements to balance operator loads?)

2. Demonstrate your part flow by preparing a standard work chart

3. With the current operators and machine capacity can we meet the takt time? (Support your answer by making a standard work combination table for each operator.)

4. Conclusion, including your analysis and recommendation.
