Question

5. A work station is shown below. The station is operated 16 hours a day for 30 days a month.. All numbers in the boxes are hourly capacity. 4-15 13 в с р • What is the throughput time?.. Which station is the bottleneck station?.... What is the monthly capacity..... Assume that the company needs to produce 3000 units per month • Is the station in its present condition capable of producing 3000 units?.. . If the answer is no, specify in total how many units are needed for each station: B- D- Assume that the company needs to produce 4500 units per month • Is the station in its present condition capable of producing 4500 units?... • If the answer is no, specify in total how many units are needed for each station: A- B D

Answer 1

1. At point A both the substation has maximum hourly capacity of 3 units per station/hr. so they both will produce 6 units/hr.

2. At point B the substation has maximum capacity of producing 8 units/hr. but from point A it will get six units per hour so it has two produce only 6 units/ hr.

3. At point C both the substation has maximum capacity of producing 4 units/hr. at each station. but from point B it will get six units per hour so it has two produce only 6 units/ hr that means 3 units at each station per hour.

4. At point D the substation has maximum capacity of producing 5 units/hr. but from point C it will get six units per hour so it has two produce only 6 units/ hr.

So, the whole process combining A, B, C and D will produce 6 units/hr.

· Throughput time= (6 units/hr.)/60

                                          = 10 mins

· Bottleneck is at Station A because it is the point which create constraint for other Stations to work at their full capacity.

Daily Production= (6 units/hr.) *16hr

                              = 96 units/ day

· Monthly capacity = Daily Production * days operable

                             = 96*30

                             =2880 units/month

No, the current capacity of the station is not 3000 units.

For that purpose, we have to increase the capacity of

A= 7 units/hr. and

Capacity of all other stations remain same.

By doing so we will get 7*16*30=3360 units/month

No, the current capacity of the station is not 4500 units.

For that purpose, we have to increase the capacity of

A, B and C to 10 units/hr. and

Capacity of station D remain same.

By doing so we will get 10*16*30=4800 units/month
