Question

Best Bicycles Problem Best's Bicycles manufactures three different types of bikes: the Tiny Tike, the Adult Aero, and the Mountain Monger. Given the information in the table, calculate the required capacity for this year's production. Note that the times are given for assembly lines, so capacity calculations should be in terms of the number of lines necessary. Assume that Best Bicycles operates three shifts, each with 2,000 hours per year Demand Fore- ProcessingTime Lot Size Time Dermand Fore- Processing Time Lot Size Setup Time cast (units/year, ' minut ev'unit) (# of bikes) (minutes/setup) Bike Tiny Tike Adult Aero Mountain Monger 14.000 16,000 19,000 50 80 40 15 18 25 10 12 a. Determine the total setup time b. Determine the total operating time available c. Determine the number of assembly lines

Explanation / Answer

a Process time required: Tiny bike 14,000x8 112000 minutes per year Adult Aero 16000*10 160000 minutes per year Mountain Monger 19000*12 228000 minutes per year Total process time 500000 minutes per year Setup Time: Tiny bike 14000/15 933.33 46666.66667 Adult Aero 16000/18 888.89 71111.11111 Mountain Monger 19000/25 760 30400 Total setup time 148177.78 b Total operating time: 3 shifts/day x 2,000hours/shift/year x 60 minutes/hour = 360,000 minutes/year. c Number of assembly lines: INT (Total process time + total setup time)/ (Total operating time) +1 = INT (500,000+148,177.78)/ 360,000 + 1 2.80
