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.
Determine the total setup time
Determine the total operating time available
Determine the number of assembly lines
Explanation / Answer
Process time required:
Tiny bike: 14,000x8 = 112,000 minutes/year
Adult Aero: 16,000x10= 160,000 minutes/year
Mountain Monger: 19,000x12= 228,000 minutes/year
Total process time: 112,000+160,000+228,000 = 500,000 minutes/year
Setup Time:
Tiny bike: 1,400x50= 70,000
Adult Aero: 1,600x80= 128,000
Mountain Monger: 750x40= 30,400
Total setup time: 70,000+128,000+30,400= 228,400
Total operating time: 2 shifts/day x 2,000hours/shift/year x 60 minutes/hour
= 240,000minutes/year.
Number of assembly lines: INT (Total process time + total setup time)/ (Total operating time) +1
=INT (500,000+228,400)/ 240,000 + 1
=INT (3.04) +1 = 4
