Getting Started

Create, edit and solve a model

The following 5-steps example will guide you through the basics of PIFOP usage, from the creation to the execution of an optimization model.

Create a free account if you don't have one already.

STEP 1. Click on the New Project button.


STEP 2. Name your project and select the files you want to upload, if any. In this example, we will be using the files from the Steel Production example from the AMPL book. These files can be downloaded from here.

We support multiple modeling languages, including AMPL, GAMS, MOSEL and OPL. See supported files to learn more. For AMPL users — here is a page with all the AMPL book examples in PIFOP.

STEP 3. Double click on the files shown on the left to open them in the editor. Make whatever changes you want, if any.

You can easily invite other people to collaborate with you. See the collaboration guide to learn how.

STEP 4. When you are ready to solve the model, click on Terminal > Run in the top menu. In this example we are using GLPSOL as the solver, but there are different ways in which you can solve a model. Select the input files and press Run.

You can also enter the command directly into the terminal:
> glpsol -m steel.mod -d steel.dat

STEP 5. All done! See the results of the execution in the terminal on the right.

Use the Up/Down arrow keys in the terminal to re-enter a command you have entered previously, and use the Repeat button just above the terminal to re-enter the most recent command.
