Mathematica Link for Excel  
By adding Mathematica into your Excel platform, you can manipulate and visualize data and equations with over a thousand more functions and options. It's easy to send even large data sets from Excel to Mathematica for the kind of sophisticated analysis Excel can't do alone, and then to return the results right into your spreadsheet.

SimQuick  
SimQuick is an Excel spreadsheet that allows the user to model simple processes: waiting lines (e.g., banks, fast-food restaurants, call centers); inventory and supply chains (e.g., stores, warehouses, and simple combinations of these); manufacturing (e.g., assembly lines, batch processes, simple job shops); and projects with uncertain task times. SimQuick is accompanied by a 100 page booklet that introduces the technique of process simulation through realistic examples and exercises that utilize SimQuick.
