A Three Step Manufacturing Operation

Consider a three-step manufacturing process. Each step employs a single worker who is not cross-trained for any other step. The setup represents the amount of time the worker spends setting up the machine for each order. No units can be processed on a machine while it is being set up. The run time represents the amount of time it takes the worker to process a single unit. When a worker completes an order, he or she hands it off to the next stage.

1. If only 10-unit orders are produced, what is the average capacity of the process per 8-hour day? Assume each customer order has a 10 units requirement.

For Q1, at what order size (batch size) will there be two steps that are both bottlenecks
