6.29 Suppose the following layout is provided as the initial layout to CRAFT. The flow-between matrix and the distance matrix are given as follows. (All the ci; values are equal to 1.0.)

Given the above data and initial layout, which department pairs will not be consid- ered for exchange. b. Compute the cost of the initial layout. c. Compute the estimated layout cost assuming that departments E and F are exchanged. d. In general, when the same data and initial layout are supplied to CRAFT and MUL- TIPLE, why would one expect MULTIPLE to often (but not always) outperform CRAFT? Also, what type of data and/or initial layout would allow CRAFT to consis- tently generate layout costs that are comparable to those obtained from MULTIPLE
