Question

Suppose that a process consists of two steps each of which produces some non-conforming items. Step one has a throughput yield of 90% step two has a throughput yield of 80% what is the rolled throughput yield of the process?

O 10%
O 94%
O 170%
O 72%

Answer 1

The rolled throughput yield (RTY) for the process is calculated by multiplying the throughput yield of each step: 90% for the first step and 80% for the second step, resulting in an RTY of 72%.

Step-by-step explanation:

To calculate the rolled throughput yield (RTY) of a process, you multiply the throughput yield of each individual step. In this case, the first step has a throughput yield of 90%, which can also be expressed as 0.90. The second step has a throughput yield of 80%, or 0.80.

The formula for RTY is as follows:

RTY = Yield of Step 1 × Yield of Step 2

Therefore, the RTY for this process is:

RTY = 0.90 × 0.80 = 0.72 or 72%

The rolled throughput yield of the process is 72%.
