Unformatted text preview: et-up time setPart (a) We need to maximize monthly production. X S Y Production time per month: 139 hours, set up time 1 hour. 139 hours = 139 * 60 = 8340 minutes. 40% of 8340 = 3336 min. We can produce 3336 / 4 = 834 units of X. 60% of 8340 = 5004 min. We can produce 5004 / 3 = 1668 units of Y. 834:1668 = 1:2 Time [Min. /unit] X Y 4.0 3.0 Production [units] 834 1668 Total Production in standard units 834 (1668 * 3)/4 = 1251 2085 Machine Capacity = 2100 [units/month] of standard product. 22 Example: cont.. Part (b) We must produce both products daily. X Y S S Y X Day 1 Day 2 Production time per day: 6 hours, set up time 1 hour. Production time per month = 120 hours 120 hours = 120 * 60 = 7200 minutes. 40% of 7200 = 2880 min. We can produce 2880 / 4 = 720 units of X. 60% of 7200 = 4320 min. We can produce 4320 / 3 = 1440 units of Y. 720:1440 = 1:2 Time Production Production in [units] standard units [Min. /unit] X 4.0 720 1440 Total 720 (1440 * 3)/4 = 1080 1800 Y 3.0 Capacity = 2100 In aggregate planning we may want to reduce aggregate capacity by 10% to 15% to allow for set ups. 23 4...
