. Kinga Doll Company manufactures eight versions of its popular girl doll, Shari. The
company operates on a 40-hour workweek. The eight versions differ in doll skin, hair,
and eye color, enabling most children to have a doll with a similar appearance to them.
It currently sells an average of 4000 dolls (spread equally among its eight versions) per
week to boutique toy retailers. In simplified terms, doll making at Kinga involves three
basic operations: molding the body and hair, painting the face, and dressing the doll.
Changing over between versions requires setup time at the molding and painting stations
due to the different colors of plastic pellets, hair, and eye color paint required. Table 7.5
lists the setup times for a batch and the activity times for each unit at each step.a. What is the process capacity in dolls per hour with a batch size of 500 dolls?
b. What is the utilization of molding in dolls per hour with a batch size of 800 dolls?
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?
