In 1913, Henry Ford invented the moving assembly line. In 2013, Ford Motors is overhauling its manufacturing capabilities to improve global flexibility. The plan calls for adding eight assembly plans, six drivetrain plants, and use of 3-D printing and virtual simulation. Ford estimates that 90% of its plants will be using a three-shift model by 2017, increasing production time by 30%. Ford plans to increase its sales from 6 million cars per year in 2013, to 8 million cars per years in 2017.
