8、r dooorstep” by Megan McCoy, Associated Editor. July 2003, pp. 37-39.,Class Application,Given the information on the second page of the article about the AS/RS at the Chicago Tribune, find the foot print of the AS/RS. Assume there is a 3 inch gap on all sides of all pallets.,L = ny(y+b),= 50(52in+3in+3in) = 2900 inches = 241.67 feet,Wrow = nx(x+a),= 2(52in+3in+3in) = 116 inches = 9.67 feet,Waisle = 2Wrow + (x+a) = 290 inches = 24.17 feet,Wtotal = 2Waisle =
