Consider a three$-$workstation serial system, with one machine in workstations

one and three and two machines available in workstation two. The external flow

enters workstation one, with parameters of $\backslash$lambda $1=4$ jobs per hour and C$2$

a$(1)=0\mathrm{.}75,$

and proceeds sequentially through workstation two and then workstation three $($i$.$e$.,$

a serial system$).$ The processing time data for the three workstations are given below.

Find the system performance measures ofCTs, WIPs, and throughput for this system.

To accomplish this, you need to compute, for each workstation i$,$ C$2$

d $($i$),$ CT$($i$),$ and

WIPs$($i$).$
