THE MAIN IDEA — all supply chains are combinations of just four entities:
Define these entities and place them on a map (like Google Maps) to create an accurate supply chain model.
Run simulations of that model to see how well it performs and find where problems occur.
Fix problems and improve performance based on what the simulations show you.
Watch the three videos below; and be sure to check out the seven Frequently Asked Questions (FAQs)
1. Introduction to SCM Globe — Creating a Supply Chain from Scratch
NOTE – This video models a small supply chain in detail and defines products at the individual item level. Normally, you define products at the standard shipping case or pallet load level. For instance, if Product A is typically shipped in cases of 100 items, then define Product A using the price, weight and volume data for a 100 item case, not an individual item. Define and track products at the case or pallet level, or even at the 40 foot shipping container level.
2. Modeling and Simulating Supply Chain Operations
All supply chain models must be approximations to some degree because making absolutely precise measurements of supply chain entities in the real world is not possible. Within a single facility in a supply chain such as a factory or warehouse precision can be higher because the scale is limited and operations can be more closely controlled within a single facility. But attempting to find precise weights and measurements for every product, facility, vehicle, and route in a supply chain is not practical. For instance, vehicle speeds in the simulations must always be averages that take into account traffic conditions plus time for loading and unloading at stops on the delivery routes. Use the best data available and make estimates when needed; do not obsess over levels of accuracy beyond what is realistic (see more about this in All Supply Chain Models are Approximations).
3. Improving your Supply Chain Design based on Simulation Results
Based on what the simulations show, you will find areas for improvement in your supply chain design. Apply what you are learning in your class and what you already know about supply chains to fix the problems found in simulations. The more improvements you make the better your supply chain will perform. Learn more about analyzing simulation results and making improvements to your supply chain in “Analyzing Simulation Data“.

SAVE BACKUP COPIES of your supply chain model from time to time as you make changes. Click “Save” button next to your model in Account Management screen. There is no “undo”, but if a change doesn’t work out, you can restore from a saved copy. And sometimes supply chain model files (json files) become damaged and they no longer work, so you want backup copies of your supply chain to restore from when that happens.
NOTE: The academic version of SCM Globe supports supply chain models containing up to 15 – 20 products and a similar number of facilities, vehicles and routes. See “Tips for Building Supply Chain Models” for ways to work with these limits, and for useful techniques for building new supply chains or add new products, facilities, vehicles and routes to existing supply chains.

To load a case study from the library, click on the “View Library” button (1) in the upper right corner of your Account Management screen shown below. It will take you to the online library of case studies as shown in the second screen below.
In the library of case studies follow these steps:
- (2) Click on “Import” button next to the case study you want
- A dialog box opens, type in the name you will use for this case study model. Click “Save” in the dialog box.
- (3) Click “My Account” button in upper right corner of the screen to return to your account screen
- On your account screen, click the “Edit” button next to the supply chain you want to edit. The edit screen will open and your supply chain will be drawn on the map.
