Assume that $($i$)$ setups need to be completed first, $($ii$)$ a setup can only start once the batch

has arrived at the resource, and $($iii$)$ all flow units of a batch need to be processed at a resource

before any of the units of the batch can be moved to the next resource.

a$.$ What is the process capacity in units per hour with a batch size of $500$ dolls?

b$.$ What is the time it takes for the first batch of $500$ dolls to go through an empty process?

c$.$ Which batch size would minimize inventory without decreasing the process capacity?

d$.$ Which batch size would minimize inventory without decreasing the current flow rate?
