Summary Introduction

Interpretation: Frank Green, an independent RV repairman, is considering purchasing a home in Ames, Iowa, that he will use as a base of operations for his repair business. Frank’s primary sources of business are 10 industrial accounts located throughout the Ames area. He has overlaid a grid on a map of the city and determined the following locations for these clients as well as the expected number of calls per month he receives as given in the tabulation. Assuming a weighted rectilinear distance measurement, the optimal location of his house needs to be determined.

    ClientGrid LocationExpected Calls per Month.

Concept Introduction: When the differences between the x and y coordinates are added, then it gives the Recti-linear distance between two points along an orthogonal path.

Frank’s primary sources of business are 10 industrial accounts located throughout the Ames area. He has overlaid a grid on a map of the city and determined the following locations for these clients as well as the expected number of calls per month he receives as given in the tabulation. Assuming a squared Euclidean distance measurement, the optimal location of his house needs to be determined.

Frank’s primary sources of business are 10 industrial accounts located throughout the Ames area. He has overlaid a grid on a map of the city and determined the following locations for these clients as well as the expected number of calls per month he receives as given in the tabulation. Assuming the goal is to minimize the maximum rectilinear distance to any client, the optimal location of his house needs to be determined.
