Please give me the solution to the second question.

Five machines are arranged in a $"$U$"$ configuration as shown in the layout below. The material handling system employed is a bidirectional conveyor system. Determine the best machine arrangement given the product routing information and production rates provided below.

Solve the above problem assuming unidirectional system from A to E$.$

$\backslash$table$[[$Product$,$Machine,Production$],[1,$B$-$E$-$A$-$C$,100],[2,$C$-$E$-$D$,250],[3,$B$-$E$-$C$,400],[4,$A$-$C$-$E$,120],[5,$B$-$A$-$C$-$D$,150]]$

$\backslash$table$[[$Distance matrix$],[$From$/$To$,$A$,$B$,$C$,$D$,$E$],[$A$,,20,80,120,120],[$B$,,,40,100,150],[$C$,,,,60,70],[$D$,,,,,20]]$
