need an AI Developing

Need an AI for numerous tasks
I run a chain of grocery stores, and need to have and AI to
-Order Stock
-Manage Delivery Drivers
-Manage Stock in Warehouse with sell by dates
-Voice Activated will be cool
-Delivery Routes
-Which warehouse should the driver go to
-Big Data Analytics, What to reorder and when
- Back end for sales
- Accounts

Also We have to do simulations before putting it into the real world
Many Thanks
