"Note: Batch size of $)$ is "single piece flow"

Refer to the process flow diagram for the aircraft production line above. Name the bottleneck step. Why do you think it is important to visualize your production system?

Identify the Cycle Time $($CT$)$ for each step $($Single$-$piece flow$).$ What is the process CT$?$

Identify the batch CT for each step $($Batch $=3).$ What is the process CT $($for a batch$)?$

We were able to determine customer demand $=960$ aircraft per day $($assume one $8-$hour shift, and system is in steady state$).$ Which system$($s$)($Batch $=1,3,$ both$)$ will allow us to meet customer demand? Calculate the capacity and per unit CT for each system to justify your answer. Note: there is a difference between CT "per unit" and CT "per batch."

What is the throughput time $($TPT$)$ for an airplane when Batch size $=1?$ Batch $=3?$ Use actual cycle times above $($not takt time$)$ and assume FIFO $($i$.$e$.,$ no expediting$).$

What is the lead time $($in minutes; order to delivery$)$ for $300$ aircraft when Batch size $=1?$ How much WIP is in this system $($assume pull system in steady state$)?$

What is the lead time $($in minutes; order to delivery$)$ for $300$ aircraft when Batch size $=3?$ How much WIP is in the system $($assume push system in steady state$)?$

Discuss the results above, and answer the following questions $($on your spreadsheet$)$:

We're doing a great job! Customer demand is now $1,920$ aircraft per day. Do we need to make any improvements to the current single$-$piece flow system to meet demand? Yes$/$No$,$ why?

Before we make any improvements, what is the required takt time to meet customer demand of $1,920$ aircraft per shift $($assume single piece flow system and one $8-$hour shift$)?$
