onsider a two$-$step process. Step $1$ consists of a single resource with a setup time of $30$ minutes. Step $2$ consists of a ingle resource without a setup. The processing time at both steps is $5$ minutes per unit. When we compute the ideal atch size, we find the formula does not produce a mathematically feasible answer. What is a valid explanation for this nusual finding?

Multiple Choice

Given equal processing times, the resource without a setup will always be the bottleneck; therefore, the batch size formula does not apply since matching of capacities is not possible.

Given equal processing times, the resource with a setup will always be the bottleneck; therefore, the batch size formula does not apply since matching of capacities is not possible.

The setup time should be reduced.

The resource without a setup has excess capacity.
