Assume that for a multi-row layout of unequal-area facilities, we have the material flow matrix given in a table below.

a. By applying 2D layout software, solve the problem assuming random length and width for machines. You can copy the solution from Software in your paper.

b. calculate the cost between machines 1 and 2 based on layout you have obtained from software.

c. write set of constraints to prevent overlapping between machines 1 and 2 based on the dimensions you have defined.

FLOW	1	2	3	4	5	6
1	-	150	300	100	0	0
2		-	30	15	180	0
3			-	50	280	180
4				-	0	60
5					-	15
6						-
