Question

3 110 pts].Tile & Style Company produces kitchen and bathroom tiles in two sizes: jumbo and regular. A bundle of tiles contains 3 jumbo tiles or 8 regular tiles and is cut out of a single, larger plate. The cutting time per bundle is 2 minutes for jumbo and 3 minutes for regular. Currently, 67% of the bundles are regular, and 33% are jumbo. Typically, Tile & Style produces 200 bundles of regular tiles before it switches over and produces 100 bundles of jumbo. The switching time from one size to the other is 15 minutes in both directions. Plates are cut into tiles by a cutting machine that is available 8 hours per day Compute the effective capacity of the process (bundles per hour).

Answer 1

	Regualr	Jumbo	Mix
Unit Load	3	2	0.67x3+0.33x2=2.67
Set-up/Qty	30/200=0.15	30/100 = 0.3
Total Unit Load	3+0.15 = 3.15	2+0.3 = 2.3	3.15x0.67+2.3x0.33=2.8695

Total available time = 8 x 60 = 480 minutes

Effective capacity = 480/2.8695 = 167.28 units
