Problem #$2$

The following sequence shows four operations in an assembly process, as well as their design capacities and effective capacity ratios:

$\backslash$table$[[$Operation$,$Number of $($Parallel$)$ Machines,$\backslash$table$[[$Design Capacity$],[($units$/$hr$.)]],$Effective Capacity Ratio$],[1,4($any machine can be used if available$),120,130,150,200,90\%$
