1. Arrange x value ascending with the corresponding weight
2. Sum all the weight and calculate median of the cumulative weight
3. X optimum is define if partial sum first equal or exceeds one-half the total
4. Repeat steps to get the optimum value of Y.
The total weighted distance resulting from the location x = (5, 4) is:
Minimum f(x) = max [(│x - ai │ + │y – bi │, I = 1,2,…m]
Formula 2.6: Total weight distance
f(5,4) = 5(I5 - 11 + I4 – 1I) + 6(I5 – 5I + I4 – 2I) + 2(I5 – 2I + I4 – 8I) +
4(I5 – 4I + I4 – 4I) + 8(I5 – 8I + I4 – 6I)
= 35 + 12 + 14 + 4 + 40
= 105
