Question 1
The operations manager for Fine Foods Distribution has narrowed the search for a new facility to seven communities. Fixed costs (land, buildings and equipment) and variable costs (labour, materials etc) are shown below.
| Community | Fixed Costs ($millions) | Variable Costs ($) |
|---|---|---|
| Aurora | $1,600 | 17 |
| Boulder | 2,000 | 12 |
| Cranbrook | 1,500 | 16 |
| Deerfield | 3,000 | 10 |
| Essex | 1,800 | 15 |
| Farber | 1,200 | 15 |
| Grafton | 1,700 | 14 |
| Community | FC | VC |
| Aurora | 1600 | 17 |
| Boulder | 2000 | 12 |
| Cranbrook | 1500 | 16 |
| Deerfield | 3000 | 10 |
| Essex | 1800 | 15 |
| Farber | 1200 | 15 |
| Grafton | 1700 | 14 |
| a. Essex that has FC of 1800 and VC of 15 is higher than Grafton for both. Hence can be eliminated | |
| Also, Aurora with FC of 1600 and VC of 17 is higher than Cranbrook for both. Hence can be eliminated | |
| Further, Cranbook can be eliminated as FC of 1500 and VC of 16 is higher than Farber |
| b. Total cost for remaining communities are plotted below |
| Different graphs have different slopes and will intersect at different points | ||||
| Farber and Grafton will intersect at X = 500 | ||||
| Farber and Boulder will intersect at X = 267 | ||||
| Farber and Deerfield will intersect at X = 360 | ||||
| Grafton and Boulder will intersect at X = 150 | ||||
| Grafton and Deerfield will intersect at X = 325 | ||||
| Boulder and Deerfield will intersect at X = 500 | ||||
| So the earliest cutoff point is X=150. | ||||
| Till X=150 none of the graphs intersect hence the range for lowest cost for each | ||||
| community is from X = 0 to 150 |
| c. Using locational break-even analysis, calculate the break-even quantities to | ||||||||
| determine the range over which each community provides the lowest cost. | ||||||||
| For Farber, Fixed cost = qty x VC | ||||||||
| 1200 = 15x i.e. x = 80 | ||||||||
| For Grafton, 1700 = 14x | ||||||||
| i.e. x = 121.43 ~ 122 | ||||||||
| For Boulder, 2000 = 12x | ||||||||
| i.e. x = 166.67 ~167 | ||||||||
| For Deerfield, 3000 = 10x | ||||||||
| i.e. x = 300 | ||||||||
| So the range of breakeven quantities are 80 to 300 | ||||||||
| However, beyond X = 150, grafton and boulder intersect as seen in part b above | ||||||||
| So the range of breakeven quantities over which each community provides lowest cost is 80 to 150 |
