2 New Actuator Product for furniture Mfg 4 Given the following information 5 Proposed Route Sheet 7 Part Actuator Part # A0001 Operation Number Mach Capacity 10 Machine Number Ps/hr 12 13 14 15 16 1 178 18 19 10 15 20 25 30 35 Press Press Press Press Break Punch Weld Weld 12 800 12 800 12 800 35 100 66 120 80 40 80 60 4 20 CEO wants to determine investment in equipment if demand is 300,000 units/yr or 500,000 units/yr 22 Standard production runs 2 shifts@ 8 hours/shift 23 Company standard is 20 working days/month 24 Employees are given 2, 15 minute breaks each shift 25 The press runs during working hours, all other equipment requires the parts to be loaded 26 Maintenance claims a 90% uptime for all its equipment 27 28 Production Planning wants to minimize press set ups to 12 per month because they take 1 hour 29 Weld set ups take only 10 minutes so the plan is for 40 per month 30 31 What would be the investment in terms of number of pieces of equipment to purchase? 32 What would be the optimal annual volume to run based on equipment investment?Explanation / Answer
Gross machine time per year for Pess = 2shifts*8hours*20days*12months*90% = 3456 hours
Available Run time per year for Press = Gross machine time - Setup time = 3456 - 12*12*1 = 3312 hours
Gross machine time per shift for other equipments = 8 hours - 2*15 minutes break = 7.5 hours
Gross machine time per year for other equipments = 2shifts*7.5hours*20days*12months*90% = 3240 hours
Available Run time per year for other equipments = 3240 hours
Available Run time per year for Weld = Gross machine time - Setup time = 3240 - 12*40*10/60 = 3160 hours
______________
Press operation time per pc = 3 operations * 12 machines * 60 minutes per hour / 800 = 2.7 minutes
Press Break operation time per pc = 35*60/100 = 21 minutes
Punch operation time per pc = 66*60/120 = 33 minutes
Weld operation time per pc = 80*60/40 + 80*60/60 = 200 minutes
Investment required for Demand = 300,000 units/yr
Number of Press equipments required = Demand rate * Press operation time per pc in hrs / Available Run time per year for Press = 300000*(2.7/60)/3312 = 5 equipments for each Press operation
Number of Press Break equipments required = Demand rate * Press operation time per pc in hrs / Available Run time per year for Press = 300000*(21/60)/3240 = 33 equipments for Press Break operation
Number of Punch equipments required = Demand rate * Press operation time per pc in hrs / Available Run time per year for Press = 300000*(33/60)/3240 = 51 equipments for Press Break operation
Number of Weld equipments required = Demand rate * Press operation time per pc in hrs / Available Run time per year for Press = 300000*(200/60)/3160 = 317 equipments for Press Break operation
Investment required for Demand = 500,000 units/yr
Number of Press equipments required = Demand rate * Press operation time per pc in hrs / Available Run time per year for Press = 500000*(2.7/60)/3312 = 7 equipments for each Press operation
Number of Press Break equipments required = Demand rate * Press operation time per pc in hrs / Available Run time per year for Press = 500000*(21/60)/3240 = 55 equipments for Press Break operation
Number of Punch equipments required = Demand rate * Press operation time per pc in hrs / Available Run time per year for Press = 500000*(33/60)/3240 = 85 equipments for Press Break operation
Number of Weld equipments required = Demand rate * Press operation time per pc in hrs / Available Run time per year for Press = 500000*(200/60)/3160 = 528 equipments for Press Break operation
