$8\mathrm{.}1.$ Revisit the copying service in Example $8\mathrm{.}1$ and assume that over the years, the monthly demand from the four customers has increased to the following weights: $w1=7,w2=9,w3=5,w4=7.$ If we previously located the copying service at point $A$ in Figure $8\mathrm{.}6,$ should we now consider a relocation?

FIGURE $8\mathrm{.}6$ Locating a Copying Service Using Cross$-$Median Approach

Description

Because of the urban location, a metropolitan metric is appropriate. A site located by the cross$-$median approach will be used to solve this problem. First, the median is calculate

Median $={\displaystyle \underset{i=1}{\overset{n}{}}}\frac{w_i}{2}$
