Cost Savings for each pair of customer locations:
Let saving be denoted by ‘s’ and cost by ‘c’.
s12 = c01 + c02 – c12 = 33.5 + 30.4 – 10 = 53.9
s13 = c01 + c03 – c13 = 33.5 + 22.4 – 11.2 = 44.7
s14 = c01 + c04 – c14 = 33.5 + 7.1 – 26.9 = 13.7
s23 = c02 + c03 – c23 = 30.4 + 22.4 – 11.2 = 41.6
s24 = c02 + c04 – c24 = 30.4 + 7.1 – 25 = 12.5
s34 = c03 + c04 – c34 = 22.4 + 7.1 – 15.8 = 13.7
Customer Pair Ranking in diminishing order of saving amounts:
Rank = (1,2), (1,3), (2,3), (1,4), (3,4), (2,4).
For pair (1,2), load = 85 + 162 = 247 (less than truck load of 250).
So one route will cover customer locations 1 and 2 from the bakery.
No other customer location can be covered in that route as it will exceed truck capacity.
For pair (3,4), load = 26 + 140 = 166 (less than truck load of 250).
So second route will cover customer locations 3 and 4 from the bakery.
No other customer location can be covered in that route as it will exceed truck capacity.
