Problem #2

Hren Electronics is in process of setting a new office building. The following tables show the number of expected communications among the four departments and two possible layouts for considerations (tables 2 and 3 show the distance among the departments in the given layout). Calculate a total cost (or total distance traveled) for each layout and provide a recommendation that would minimize the total costs.

Table 1. Number of transactions
	A	B	C	D
A	0	75	20	0
B	5	0	300	100
C	10	0	0	0
D	0	20	0	0
Table 2. Layout 1 (Walking distance in meters)
	A	B	C	D
A	0	10	20	30
B	10	0	10	20
C	20	10	0	10
D	30	20	10	0
Table 3 Layout 2 (Walking distance in meters)
	A	B	C	D
A	0	5	30	40
B	5	0	5	20
C	30	5	0	20
D	40	20	20	0
