Model version control with Git integration and the new ALPX file format

Collaborative modeling in progress


Collaborative modeling has always been an important direction in AnyLogic development. We know how beneficial teamwork is when each person involved in a project can seamlessly step into the process, keep track of versions, and be on the same page with the team.

We embrace the same experience for our users, so in AnyLogic 8.9, we added seamless Git integration for model version control and a new .alpx file format.

If you work in consulting and frequently manage both teamwork and complex simulation modeling projects, check out our white paper to learn how simulation can advance your problem-solving approaches.

In this blog post, we want to highlight how well these features work in tandem and how they streamline the collaboration and facilitate better model version control.

Introducing the ALPX model format

To simplify and enhance model version control in AnyLogic, we introduced a new file format — ALPX. This offers a more organized and readable model structure, leading to:

  • improved code organization
  • revised maintainability
  • streamlined model version control

Let’s see in detail how these aspects influence the collaborative modeling experience.

Improved code organization

The .alpx format breaks complex models into smaller, manageable .xml files, making it easier to navigate and maintain. This approach supports the goals of seamless collaborative modeling, allowing multiple team members to work on different parts simultaneously. By dividing the model, teams can focus on specific sections, improving productivity and reducing errors.

In model version control, fragmenting the model simplifies tracking changes and resolving conflicts. Each .xml fragment can be versioned independently, making it easier to manage updates and ensure consistency across the model. Think of it as breaking a long, complex text into well-defined chapters—much easier to navigate!

Revised maintainability

With model fragmentation, developers can focus on specific elements without affecting unrelated sections of the model. It enables team members to work simultaneously on different aspects and reduces the risk of conflicts when integrating changes, a common issue in collaborative modeling.

Additionally, the modular nature of the .alpx format enhances model version control by making it easier to track changes to individual components instead of the whole model. This ensures that each modification is confined to its relevant area and reduces the risk of bugs.

Streamlined model version control

The .alpx format allows Git to track changes more efficiently because of its inner segmentation. This boosts model version control, enabling more granular tracking and modification of each component.

Now, only the modified parts are versioned, providing a clear history of changes. In collaborative modeling, where multiple team members work on different sections, such precise versioning is essential. It allows each modeler to maintain control over their contributions while easily coordinating with the rest of the team. By offering precise control and clear tracking, this structure makes model version control more efficient and manageable.

The next step to collaborative modeling with Git integration

Imagine a team working on an intricate simulation model. Constant changes and updates are inevitable, but effective model version control could be challenging without proper tools. Integration with Git, a popular version control system, eliminates these hurdles.

Now, you can connect AnyLogic with your Git repository, allowing you to:

  • Track model history: Every change made to your model is meticulously recorded in a Git repository. This allows you to quickly revert to previous versions if needed and provides a clear audit trail of development.
  • Facilitate collaborative modeling: Multiple developers can work on the same model simultaneously without worrying about conflicts. Git's merge capabilities ensure smooth integration of changes, guaranteeing everyone works on the latest version.
  • Improve code visibility: With Git, the model code is more transparent. Developers can readily assess changes made by others and understand the reasoning behind them, fostering better communication and collaborative modeling.

Synergy of Git and ALPX for improved model version control

The combination of Git and the .alpx format offers a robust framework for managing complex models. Git provides a strong foundation for convenient model version control, allowing developers to work together in a shared environment while maintaining a clear and well-organized track of changes. Meanwhile, the .alpx format structures the code into manageable fragments, enhancing maintainability and reducing the risk of errors.

Together, these tools streamline collaborative modeling and model version control, leading to faster development cycles.

The fragmented structure of .alpx, combined with Git's ability to track individual parts, facilitates communication between modelers and reduces the likelihood of conflicts. This approach elevates the overall collaborative modeling experience.
