Consider the following example. A company that makes industrial pumps wants to prepare a master production schedule for June and July. Marketing has forecasted demand of $120$ pumps for June and $160$ pumps for July for its major product. These will be evenly distributed over the four weeks in each month: $30$ per week in June and $40$ per week in July, as illustrated in Figure $12-6.$

Now, suppose that there are currently $64$ pumps in inventory $($i$.$e$.,$ beginning inventory is $64$ pumps$),$ and that there are customer orders that have been committed $($booked$)$ and must be filled $($see Figure $12-7).$

Prepare another master scheduling table for the pumps of Figure $12-11$; use the same inputs as the example, but change the master scheduling rule from $$schedule production when the projected on$-$hand inventory would be negative without production$$ to $$schedule production when the projected on$-$hand inventory would be less than $10$ units without production.$($Do not leave any empty spaces; input a $0$ wherever it is required.$)$
