A Printed Circuit Board (PCB) machine installs integrated circuits onto a board. Before starting to produce a board, ihe PCB machine requires a 18-minute setup. Once in production, the PCB machine requires only 0.13 minute per poard. (Do not round intermediate calculations. Round your answer to 2 decimal places.) boards pel Currently, the PCB machine produces 500 boards between setups. what is the capacity of the PCB machine (in boards per minute)? minute (Do not round intermediate calculations. Round your percentage answer to 2 decimal places.) b. Currently, the PCB machine produces 500 boards between setups. Given this operating process, percent what is the utilization of the PCB machine? Say the PCB machine produces 300 boards between setups and demand is 4 boards per c. minute. Given this operating process, what is the average inventory of boards at the PCB machine? (Round your final answer to 2 decimal places.) d. Demand for boards occurs at the rate of 4 boards per minute. What is the smallest batch size batch size such that the PCB machine does not constrain the flow rate through the process
