$2\mathrm{.}2.(4\mathrm{.}0$ points$)$ A severe winter ice storm has swept across the region. These weather conditions have resulted in different constraints:

Due to the time weather conditions, nights were canceled, and location D cannot be supplied from supply depot $4$;

All the stored material at supply depot $4$ should be shipped.

What would be the effect on the optimal solution? Determine the daily schedule that will minimize total transport time under these conditions?

During a humanitarian crisis large amount of material and supplies need to be daily shipped from supply depots to different locations. One of the critical factors in the movement of these supplies is speed.

The following table shows the number of planeloads of supplies available each day from six supply depots and the number of daily loads demanded at each of five locations. $($Each planeload is approximately equal in tonnage.$)$ Also included in the table are the transport hours per plane $($where transport hours include loading and fuelling time, actual flight time, and unloading and refuelling times$).$
