B: Maintain low set up times/ keep costs low
D: Keep batch sizes at the current level
A: Run the heat treat efficiently so we can get the most money out of it
D-D':Assumption(s)Injection(s)
I cannot have two different batch sizes in the machine at onceI purchase another heat treat machine
C: Decrease lead time/ increase product turn-around
D': Cut batch sizes in half

In order to Run the heat treat efficiently so we can get the most money out of it I must Maintain low set up times/ keep costs low and in order to Maintain low set up times/ keep costs low I must Keep batch sizes at the current level. But, in order to Run the heat treat efficiently so we can get the most money out of it I must also Decrease lead time/ increase product turn-around and in order to Decrease lead time/ increase product turn-around I must Cut batch sizes in half. I can't both Keep batch sizes at the current level and Cut batch sizes in half.

B-DSmaller batch sizes will double the amount of set ups that must be doneWith less time on each process, no time would be wasted doing more set ups
C-D'The time it takes to process the batch will be cut in halfOn very large orders to the same person, cutting the batch sizes would double the time it takes for them to get there order
A-BIf costs increase, that will increase the liklihood of the plant being shut down.If customers get their order faster, it may lead to more business which would balance out the higher cost
A-CFaster turn-around on the heat treat will lead to the ability to process more ordersNot if there are no more orders to process
