Question $2-$ Transfer Lines

A $20-$station transfer line is divided into three stages of $6,6,$ and $8$ stations.

There are zero$-$capacity buffers between the stages $($effectively the same as no

buffers$).$

The processing times and breakdown rates of the stations in each stage are

shown in the three following tables:

Stage $1$

Stage $2$

Stage $3$

Assume that the downtime is constant when a breakdown occurs, $T_d=5\mathrm{.}0$min.

The repositioning time $(T_r)$ is also constant, and is $30$ seconds.

$2$a$)$ Calculate the ideal cycle time $(T_c)$ for this line. $[6$ Marks$]$

$2$b$)$ Calculate the average production time $(T_p)$ for this line. $[8$ Marks$]$

$2$c$)$ Calculate the line efficiency of the line $(E_0),$ remembering your buffers

have no storage capacity. $[7$ Marks$]$

what is E$0$
