Hub and Spooke delivery

[TejinderSingh]

Hello 
I am have very little experice with ARC GIS but have worked a lot with QGIS, 

What i am tryiing to achieve is some sort of analysis on moving from point to point delivery model to a multiple hub and spoke model.
In current model a small buisness is On-demand courier company, where there are different trips called in through out the day, and there are multiple origins and destinations, there is no common hub. For example : 
A to B
C to D
A to D
E to F

I want to check feasebility of multiple hub and spoke model, where there are handoff points between origin and destinations. for example 

A to (hub) to B and D

what are my options to answer following quiestions ? 
1: Where should the hubs be ?
2:  How many deliveries will hubs receive ? 
3: If i select few points as hubs myself ? how many deliveries will my hubs recieve ? 

I have about 2 months of historical data from this buisness in form of Origin and Destination Points 

thanks

At first glance, this seems to be a Location-Allocation problem (requires network analyst).  Based on your historical data, you could create multiple candidate hubs (points) based on historical delivery patterns/clusters (maybe check out the tools in the  Mapping Clusters toolset in the Spatial Statistics toolbox to find clusters), then use Location-Allocation to choose a subset of facilities (hubs) that minimizes travel time from the hub to the demand (delivery) points.  The size of the subset is up to you - you may have a hard constraint such as number of hubs you can have, or the capacity of the hubs (number of packages it can store).

The Make Location-Allocation Analysis Layer geoprocessing tool describes the different types of location problems that can be solved.  

See Location-Allocation Analysis Layer document for a description of the inputs.
