The results were similar to all variables regardless of the blood type, as the same number were repeated until day 34. If we attempt to interpret the results, we could see that the coefficient of the collected units could decrease by 720 or increase by the same, and that wouldn’t impact our optimal solution. On the other hand, the coefficient of the units in inventory could decrease to 0 or increase to infinity and that wouldn’t change our optimal solution. That is logical because we are trying to maintain a fixed inventory for all blood types. Regarding the very first line of the sensitivity report, having an upper limit of infinity makes sense because we are already collecting in excess vis-à-vis other days. Yet, the allowable decrease on the 35th day is big, and that could be interpreted in the sense that we already have enough inventory to satisfy that day’s need, therefore if we decrease or increase its coefficient by 720 up and down, nothing will change when it comes to the optimal solution; and the same thing applies to the inventory.
The second line of code gave the following output:
