How to perform supply and demand with orchards to distribution center

Hi everyone,

I have been stuck on a problem. I searched through the ESRI forums, but couldn't find anything that helped me. If anyone could lend some guidance or point me in the right direction, it would be greatly appreciated.

Here is the problem, it gets a bit complex, but having certain components working would also be appreciated:

I have 100 different fruit orchard points which are supply
I have 5 different distribution centers which are demand
I  know the number of trucks and their capacity

What I want to get from this is:
- The route visualized
- The route (ie. The truck goes from this point to this point)
- I also want the number of times the truck can travel in a time frame, but its not necessary as I'm trying to do this one step at a time.
* The route would be the shortest distance

For a simple example, if I am given:
- Orchard A has 50 apples supply
- Orchard B has 50 apples supply
- Distribution Center has a demand of 100
- A truck that has a capacity of 10

I basically want the thing to spit out for the truck to go back and forth between Orchard A until it is depleted, and then go to orchard B until it is depleted. I assume it will tell me the time travelled in which I can figure out how many trips in a day it can make.

I have tried to be as detailed as possible, if anyone would like some clarification, it would be fantastic:D

You should use the Vehicle Routing Problem solver.
First, read about it here:
Run through the tutorials to get familliar with it:

You will need to model your vehicles in a slightly different way. Since you want to reuse the trucks, enter them more than once so that they can be reused to go back for another load.
