To determine the bottleneck and bottleneck time, we need to calculate the throughput time (i.e., the time it takes for a unit to go through the entire process) and the capacity of each operation.

Throughput time: Drilling = 1 / 2 = 0.5 hours/unit Sawing and Sanding = 1 / max(6, 2.5) = 0.167 hours/unit Assembly = 1 / 0.8 = 1.25 hours/unit

The bottleneck is the operation with the longest throughput time, which is Drilling.

Capacity: Drilling = 2 units/hour Sawing = 6 units/hour Sanding = 2.5 units/hour Assembly = 0.8 units/hour

The bottleneck time is the amount of time it takes for the bottleneck operation to complete one unit of production. Therefore, the bottleneck time for Drilling is 0.5 hours/unit, or 30 minutes/unit (since 1 hour = 60 minutes).

So the answer to (a) is: Drilling is the bottleneck. The answer to (b) is: The bottleneck time is 30 minutes per unit.

Explanation:

We need to calculate the throughput time (that is, the amount of time it takes for a unit to go through the entire process) as well as the capacity of each operation so that we can determine the bottleneck and the time at which the bottleneck will occur.

Time required for throughput: drilling equals one half of two, or half an hour per unit Sawing and Sanding = 1 / max(6, 2.5) = 0.167 hours/unit 1.25 hours are required for assembly for each unit, which is calculated as follows:

The operation that has the longest throughput time is the one that is causing the bottleneck, and that operation is drilling.

Drilling has a capacity of two units per hour. Sawing is equal to six units per hour Sanding is equal to 2.5 units per hour Putting Together = 0.8 Units Per Hour

The amount of time that must pass through the bottleneck operation in order to finish one unit of production is referred to as the bottleneck time. Because of this, the bottleneck time for Drilling is 0.5 hours per unit, which is equivalent to 30 minutes per unit (given that 1 hour is equal to 60 minutes).

Therefore, the answer to question (a) is that the drilling process is the bottleneck. The correct response to question (b) is that the bottleneck time is thirty minutes for each unit.

what is question c? how many minutes?
