Question 2 (25 points) Consider BLOCPLAN. Suppose the following REL-chart and layout are given for a five-department problem. (It is assumed that each grid in the layout represents a unit square.) Further suppose that the following scoring vector is being used: A = 10, E= 5, I=2, 0 = 1, U = 0, and X=-10. 1 2 3 4 5 1 A U U | 4 1 E U U I 3 U X 4 A 5 3 2 5 1 a. Compute the efficiency rating. b. Compute the REL-DIST score. c. In improving a layout, BLOCPLAN can exchange only those departments that are either adjacent or equal in area. True or false? Why? (If true, then explain why there is such a limitation. If false, then explain how two departments that do not meet the above constraint are exchanged.) d. In constructing and improving a layout, BLOCPLAN maintains rectangular department shapes. Discuss the advantages and limitations of maintaining such department shapes in facility layout
