Given this set of daily service operations, and assuming a processing order of A$-$B$-$C$-$D$-$E:

Service Operation Number of Daily Reps

A $42$

B $32$

C $24$

D $38$

E $28$

a$.$ Determine the number of repetitions for each service if four cycles are used.

Hint: Include one more unit of A in Cycles $1$ & $2$ than in Cycles $3$ & $4.$ Include one more unit of D in Cycles $3$ & $4$ than in Cycles $1$ & $2.$ This will result in the same total number of units $($repetitions$)$ in each cycle.

b$.$ Determine the number of repetitions for each service if two cycles are used.
