A semi$-$automated assembly machine, assembles and welds automotive components for a single shift of $7\mathrm{.}5$ hours, $5$ days a week; planned throughput $=150$ units$/$hour; actual output $=2,875$ units$/$week$.$ The following losses are encountered during assembly:

Incorrect assembly causes the machine to stop and needs re$-$set on average $5$ times$/$hr$.$ where $1$ unit and $2$ minutes are lost. $($This leads to performance loss due to minor stoppage and also quality loss

Worn out electrodes are to be replaced once per week, it takes $1$ hour when $30$ units are scrapped $=>>$ availability and quality losses

Burst out cooling hose causes a machine breakdown once in a month and replacement takes $5$ hours $=>$ availability loss
