You have been asked to put together a capacity plan for a critical bottleneck operation at the Surefoot

Sandal Company. Your capacity measure is number of machines. Three products $($men$`$s$,$ women$`$s and

children$`$s sandals$)$ are manufactured. On average, about $10,000$ sandals are in various stages of

production. The time standards $($processing and setup$),$ batch sizes, and demand forecasts are given in

the following table. The firm operates two eight$-$hour shifts, five days per week, fifty weeks per year.

Experience shows that a capacity cushion of $5$ percent is sufficient.
