A production process at Brianna Bryant Manufacturing is shown in the figure below. The drilling operation occurs separately from, and simultaneously with, the sawing and sanding, which are independent sequential operations. A product needs to go through only one of the three assembly operations (the operations are in parallel).

a. The process time of a station is the time to produce a given number of units (or a batch of units) at that workstation. Bottleneck time is the time of the longest process (the slowest workstation) in the system. Calculate the process time per unit for each station.

Part 3

The process time for

Sawing=

minutes per unit (round your response to two decimal places.)

Part 4

The process time for

Sanding=

minutes per unit (round your response to two decimal places.)

Part 5

The process time for

Drilling=

minutes per unit (round your response to two decimal places.)

Part 6

The process time for

Welding=33.3333.33

minutes per unit (round your response to two decimal places.)

Part 7

The process time for overall (all 3 stations) Assembly

=

minutes per unit (round your response to two decimal places.)

Part 8

What area is the bottleneck?

b. Bottleneck time is the time of the longest process (the slowest workstation) in the system. The bottleneck time of the overall system is?

minutes per unit (round your response to two decimal places.)

Part 10

c. Throughput time is the time it takes for a product to go through the production process with no waiting.

Part 11

The drilling operation occurs separately from, and simultaneously with, the sawing and sanding operations.

The time it takes for a product to go through the sawing and sanding operations is?

minutes (round your response to two decimal places.)

Part 12

The time it takes for a product to go through the drilling operation is?

minutes.

Part 13

The longest path through the production process goes through?

minutes (round your response to two decimal places.)

d. If the firm operates

12 hours per day, 20 days per month, what is the monthly capacity of the manufacturing process?

First calculate the total work time available per month.

20

days/month12

hours/day60

minutes/hour=

minutes/month (enter your response as a whole number.)

Part 15

Then divide the total work time available per month by the bottleneck time.

The capacity of this work
