The three-station work cell has a product that must go through one of the two machines at station 1 (they are parallel) before proceeding to station 2. Station 1 Machine A Capacity: 20 units/hr Station 1 Machine B Capacity: 20 units/hr Station 2 Capacity: 2 units/hour Station 3 Capacity: 10 units/hour A. The bottleneck time of the system is? B. which station is the bottleneck station? C. The throughput time is? (in minutes) D. If the firm operates 8 hours per day, 5 days per week, the weekly capacity of this work cell is? (in units)

Solution

A.) The bottleneck time of this work cell is Station 2, which has a capacity of 2 units per hour. This becomes the bottleneck for the entire product because Station 1 can product 20 units per hour and if they both send to Station 2, that would be 40 units per hour. This would cause a delay or bottleneck because Station 2 is only able to produce or accommodate 2 units per hour.

B.) The bottleneck station is station B.

C.) Since the product must go through one of the two machines at Station 1 before proceeding to Station 2, the through put time of the system is 20 units per hour. Therefore, either Machine A or Machine B represents the process time of each assembly line.

D.) 8 hours per day
5 days per week

22 units per hour X 8 hours per day = 176 units per day
176 units per day X 5 days = 880 units per week
