Question 2: Build the following block layout model. The total available area can be described as a rectangle of length 120m by width 80m. Where, the bottom left place of size 20m by 20m is reserved for passage to the underground parking. There are four departments in total, and in general, the aspect ratio for all the departments should be 1.1. However, Department 3 must be square in shape. The upper and lower limits for both length and width are 10m and 70m. The upperand lower limits for any departments perimeter is 120m and 200m. The cost per unit flow is $1 between any two departments. The flow matrix per day between the departments as given in the following matrix. Assume any missing information, and develop an optimal block layout.
