Solution
Non adjacent departments are a pair whose none of the sides or corners touch each others\'
Number of adjacent loads for the given layout is obtained by calculating the Sum of flows between non-adjacent departments.
Number of adjacent loads for the given layout = AC+CA+AF+FA+CD+DC+DF+FD
= 100+0+20+10+0+0+300+200
= 630
__________________________________________
Calculate number of non-adjacent loads for each layout. Non-adjacent load is calculated by adding the flow between non-adjacent departments. Non-adjacents departments are those whose none of the sides or corners are adjacent (meaning they do not touch).
Number of non-adjacent loads for the above layout = AC+CA+AF+FA+CD+DC+DF+FD
= 100+0+20+10+0+0+300+200
= 630
___________________________________________
Number of non-adjacent loads for the above layout = AE+EA+AF+FA+BE+EB+BF+FB
= 10+30+20+10+50+50+0+0
= 170
______________________________________
Number of non-adjacent loads for the above layout = CF+FC+CE+EC+BF+FB+BE+EB
= 0+0+0+60+0+0+50+50
= 160
______________________________________
Number of non-adjacent loads for the above layout = CF+FC+CD+DC+BF+FB+BD+DB
= 0+0+0+0+0+0+0+0
= 0
Number of non-adjacent loads is the minimum for this layout. Therefore, this layout is the most efficient.
