Answer the following questions for CRAFT.

a. State two principal weaknesses and two principal strengths of CRAFT.

b. CRAFT uses the estimated cost in evaluating the potential impact of exchanging two or three department locations. Suppose we modify the original computer code to obtain a new code, say, NEWCRAFT, where we always use the actual cost in evaluating the potential impact of exchanging two or three departments. Assuming that we start with the same initial layout and that we use the same exchange option

(such as two-way exchanges only, or any other exchange option), the cost of the final layout obtained from NEWCRAFT will not necessarily be less than the cost of the final layout obtained from CRAFT. True or false? Why?
