Question

The three-station work cell illustrated in the figure below has a product that must go through one of the two machines at station 1 (they are parallel) before proceeding to station 2. Capacity: 20 units/hir Station 1 Machine A Station 2 Station1 Machine B Capacity 2 units/hr Capacity: 6 units/hr Capacity: 20 units/hr a) The bottleneck time of the system is minutes per unit (enter your response as a whole number). b) c) The throughput time isminutes (enter your response as a whole number). d) If the firm operates 12 hours per day, 5 days per week, the weekly capacity of this work cell sunits (enter your response as a | is the bottleneck station. whole number).

Explanation / Answer

Solution :

A : Bottleneck time is station 1 with capacity of 10 units/hr

B : Station 1 is bottleneck station

C : Throughput time is 6min

Throughput of system is defined as per the throughput of the bottleneck resource. In this case station 1 is bottleneck with capacity of 10 units/hr i.e. 6 min per unit

D : Capacity of work cell = Available time / Capacity of bottleneck = (12 * 60 * 5) / 6 = 600 units per week
