Speed Up – Unfreeze – Debug Your Simulation

Use the Google Chrome or Apple Safari web browsers. SCM Globe simulations do run under Firefox, but sometimes they run slowly, and other problems sometimes occur under Firefox. Simulations will completely freeze up under the Microsoft browser!

Slowdowns will occur on people’s’ PCs when they have other programs running and/or because they have a lot of browser tabs open. SCM Globe will run faster if you close all other programs running on your PC except your Internet web browser. In your browser, close all other open browser tabs except for one tab where you have the Edit screen and one other tab where you have the Simulate screen.

Set “Speed” option to “Fastest” on the simulation screen. In the upper right side of the simulation screen see the option to set the speed of execution for the simulation. Choices go from Normal to Fast and Fastest.

Reboot your PC. Rebooting will free up memory and generally refresh and reset your computer and web browser settings and resource usage. So turn off your computer and turn it on again. That could clear up your problem.

If you have a slow Internet connection or old or low powered PC it will cause your simulation to run slowly. Simulations run partly on SCM Globe application servers and partly in the browser on your own PC or laptop or tablet. So simulations run best on newer computers with more memory and faster processors with high speed Internet connections.

After making repeated changes to data for any of the four entities (products, facilities, vehicles and routes) your model may seem to freeze up because it is synchronizing data between your computer and our servers. Just click your browser refresh button to clear that up. And remember to click the browser refresh button (on Chrome it is in the upper left corner of browser) when you flip over to the simulation screen. If you don’t refresh the browser tab or click on the “Reload Supply Chain” button, the simulation won’t reflect any of the changes you made in the edit tab.

If a particular route in your case study has been moved several times because a connected facility was moved, or if you have added and removed facilities or vehicles several times from this route the data synchronizing sometimes becomes confused. You’ll see this when you try to edit such a route. It will have no stops or erroneous stops and drop quantities. When this happens it is best to make note of the facilities and products on that route and delete the route. Then re-create the route from scratch to clear up this problem.

Make sure there is an entry and not a blank for each field describing the entities (products, facilities, vehicles, routes) in your supply chain model. Depending on the data field, entries can be character or numeric. Do not put character data in numeric fields. All numeric fields for an entity are initially populated with zeros; other numeric values can be entered in numeric fields but do not leave numeric fields blank.

Restore your supply chain from an earlier copy of the supply chain that you saved in a save state. As described in the Getting Started section and in each of the supply chain introductions, it is good practice to periodically make copies of your supply chain model as you work on it. If your present supply chain model is not working, then restore an earlier copy of the supply chain. See instructions in Download and Share Supply Chain Models

If you did not make backup copies of your supply chain, try saving your case study to a save state. Click on My Account button to go to your account screen. There are two sections on the account screen labeled “Supply Chains” and “Save States”. Click the Save button next to your case study in the Supply Chains section and it will create a save state. Then delete the case study from the supply chains section and click the Restore button next to the case study in the Save States and it will be restored to the Supply Chains section. Then click edit button next to the case study to open the case study and edit it and click Simulate button to run the simulation.

If none of these options work there is still another option. Go to your Account screen and scroll down to your Save States. Click the “Download Save State” button next to the case study and notice that it downloads a file to your PC. This file ends with the extension of “.json”. Then click on the Upload Save File button in the middle of the account screen. This will open up a file directory window and you can find the .json file that was downloaded and click on it to upload it again into your account. Then click on edit button next to the uploaded file and start working on it again.

The last option if none of the above options solved your problem; make notes of the changes you made to your supply chain to date and reload the case study original model from the SCM Globe library. If you are working on a supply chain model you created on your own, then reload from an earlier save state that you made of your model. Then edit that reloaded supply chain model to include the changes you made previously.

You can also click on the “Support Ticket” button in the upper right corner of the screen and send us an email describing your problem. Support tickets are answered within 24 hours.If you wish, you can send us a copy of your simulation that is running badly. Make a save state and download it to your PC – see Download and Share Supply Chain Models. Attach that file (a .json file) to an email and send it along with a description of your problem to info@scmglobe.com.
