Capacity Balancing Capacity balancing is to ensure quantity harmony between the capacities of downstream machines. Ex $5$: A product is produced as a result of four consecutive processes such as A$,$ B$,$ C and D$.$ Necessary time periods of the operations are given below. Find the number of machines and efficiency for the full, normal and improved capacity of the production system. Processes a$=6($Min$/$Unit$)$ b$=5($Min$/$Unit$)$ c$=4($Min$/$Unit$)$ d$=3($Min$/$Unit$)$
