2. CRAFT (COMPUTERIZED RELATIVE ALLOCATION OF FACILITIES TECHNIQUE):
Definition:
It is a tool that used to help improve the
existing layout of the facilities. The facility is
improved by swapping two or more departments to
help arrange the facility to an optimal floor plan.
Inputs of CRAFT :
• From-To Chart
• Cost Matrix
• Distance (Determined)
• Initial Layout
3. When will CRAFT be used?
• CRAFT is used when the number of departments is enormous
that the manual computation would be nearly impossible to
do. CRAFT is basically used with process layout approach.
What does the CRAFT do?
• CRAFT do uses a pair wise exchange algorithm. It examines
all the possible swaps, and it considers the swap of only
adjacent department pair or pairs that have the same area.

6. COFAD (Computerized Facility Design):
• Its objective is also to minimize material-handling cost.
Input Data:
• Initial layout
• from-to matrix
• move cost equations
• Fixed path equipment (conveyors, cranes, hoists, etc. )
FPMC = FPFC + FPVC * ML
VPMC = VPFC * EUT + VPVC * MTIME
