Suppose that we have a process that produces two types of an item: Blue Item and Orange Item. Both of the items require the same pure sequential operations: O1, O2, O3. O1 and O3 are manual operations. O2 is the main and an automated operation which differentiates the items (e.g. gives different colors). Operation 1 takes 1 minutes per item. It is a manual operation that is common to both types. Operation 2 takes 4 minutes per item. It is an automated operation. Operation 3 takes 2 minute per item. It is a manual operation that is common to both types. Draw the GANTT Chart, calculate the flow time, cycle time, throughput, value added time and waste when the setup time for machine 2 where the Operation 2 occurs is 2 minutes and the batch size is 3 items per batch.
