Problem $6-15($Algo$)$

An assembly line is to operate eight hours per day with a desired output of $225$ units per day. The following table contains information on this product's task times and precedence relationships:

$\backslash$table$[[$TASK$,\backslash$table$[[$TASK TIME$],[($SECONDS$)]],\backslash$table$[[$IMMEDIATE$],[$PREDECESSOR$]]],[$A$,90,-],[$B$,50,$A$],[$C$,45,$A$],[$D$,40,$A$],[$E$,30,$B$,$ C$],[$F$,60,$C$,$ D$],[$G$,45,$E$,$ F$],[$H$,70,$G$]]$

b$.$ What is the required workstation cycle time to meet the desired output rate? $($Round your answer to the nearest whole number.$)$

Workstation cycle time

seconds per unit

c$.$ Balance this line using the longest task time. $($Leave no cells blank $-$ be certain to enter $"0"$ wherever required.$)$
