Question

essed at workstation B for 10 min. per unit. Part 2 is simultaneously processed at workstation C for 20 min per unit. Work stations B and C feed the parts to an assembler at workstation D, where the two parts are assembled. The time at workstation D is 15 minutes.Klassen Toy Company, Inc., assembles two parts: Part 1 is first processed at workstation A for 15 minutes per unit and then processed at workstation B for 10 min. per unit. Part 2 is simultaneously processed at workstation C for 20 min per unit. Work stations B and C feed the parts to an assembler at workstation D, where the two parts are assembled. The time at workstation D is 15 minutes.
a. what is the bottleneck of this process?
b. what is the hourly capacity of the process?

Answer 1

Answer:

a) Process A is the bottleneck of the process

b) Hourly capacity = 60 / bottlenecktime = 60/25 = 2.4 units / hour

Explanation:

Part 1 is processed at A for 15 minutes and then at B for 10 minutes.

Thus part 1 take 15 + 10 i.e. 25 minutes two complete both processes

Part 2 is processed at C for 20 minutes.

Output from B and C i.e. part 1 and 2 respectively are fed to process D where the time taken to assemble is 15 minutes

Thus looking at the given data,

Part 1 takes longer time i.e. 25 minutes to reach process C compared to part 2 i.e. 20 minutes

So bottleneck occurs at process A and B because it takes maximum time i.e. 25 minutes

a) Process A is the bottleneck of the process

b) Hourly capacity = 60 / bottlenecktime = 60/25 = 2.4 units / hour
