Consider a company$$s sales in $2003$ and $2004.$ We want

to rank the value of each customer based on these data.

Three parameters contributing to this decision are $(1)$

Forecasted sales, $(2)$ Sales this year, and $(3)$ Change in

sales from last year. The subjective weights assigned to

each parameter are $(1)0\mathrm{.}4,(2)0\mathrm{.}3,$ and $(3)0\mathrm{.}3.$ Value

functions are shown in the figures.

Consider customer X$,$ with expected sales of $$70$ million,

present sales of $$40$ million, and a most recent annual

sales increase of $20\%.$ Compare the value of this

customer with the value of customer Y with expected

sales of $$70$ million, present sales of $$70$ million, and

rate of change of $5\%.$
