Question 1. Assume there are 5 clients that need to be supplied from a warehouse. The following table lists the location of each of these clients in terms of respective x and y coordinate values. Client number Location in x coordinates 1 2 3 4 5 12 20 32 46 88 Location in y coordinates 11 15 24 42 65 The distance is defined in terms of the sum of rectilinear movements, in horizontal and vertical directions. (For instance, if warehouse is located at the point (x, y), then its distance from the first client is 12-x|+|11-y| .) (a) You are expected to come up with a linear programming model to choose the coordinates of the location of the warehouse such that the sum of the distances to all clients is as small as possible. (b) How you modify your model in part (a) if your objective is to minimize the largest of the five distance values?
