Explanation / Answer
Total set up time for touring bicycle
= Demand/Lot size x Standard set up time
= 5000/100 x 2
= 100 hour
Total set up time for Mountain bicycle
= Demand / Lot size x Standard set up time
= 12000/90 x 3
= 400 hour
Cumulative set up time required in a year = 100 + 400 = 500 hours
Total processing time for Touring bicycle = 5000 x 0.75 hours = 3750 hours
Total processing time for Mountain bicycle = 12000 x 0.20 = 2400 hours
Cumulative processing time required in a year = 3750 + 2400 = 6150 hours
Thus,
Cumulative set up time plus processing time required in a year = 500 + 6150 = 6650 hours
Gross available hours per workstation = 8 hours/day x 5 days/ week x 52 weeks/ year = 2080 hours
Since there is capacity cushion of 15 percent,
Effective available working hours per workstation = 0.85 x 2080 = 1768
Therefore , number of workstations required next year
= Cumulative set up plus processing time required in a year/ Effective available working hours per workstation
= 6650 /1768
= 3.76 ( 4 rounded to next higher whole number )
NUMBER OF WORKSTATIONS REQUIRED NEXT YEAR =4
NUMBER OF WORKSTATIONS REQUIRED NEXT YEAR =4
