Question: A plastic extrusion plant will be built to produce 30 million meters of plastic extrusions per year. The plant will run three 8-hr shifts per day, 360 day/yr. For planning purposes, the average run .ength = 3000 meters of extruded plastic. The average changeover time between runs = 2.5 hr. and average extrusion speed = m/mtn. Assume scrap rate = 1%, and average uptime proportion per extrusion machine = 959f during run time. Uptime proportion during changeover is assumed to be 100%. If each extrusion machine requires 500 sq. ft of floor space, and there is an allowance of 40% for aisles and office space, what is the total area of the extrusion plant?ing technique to the part-machine incidence matrix to identify logical part families and machine groups.
