FLR: An Open-Source Framework for the Evaluation and Development of Management Strategies
what is flr
What is FLR?
  • Fisheries Library in R
  • Provides extensible toolbox for Management Strategy Evaluation (MSE)
  • For example:
    • fit stock-recruit relationships and model biological stocks
    • model fleet dynamics (including economics)
    • simulate management procedures (harvest control rules)
    • Not just stock assessments (XSA, ICA etc.)
    • Etc…
philosophy of flr
Philosophy of FLR
  • Open source license (GPL): you can modify a copy of the code, but you must distribute it under the same license.
  • Collaborative: Discussions are open (mailing list), website is editable, external review is encouraged
  • Breaking the barrier between user and developer
  • Improves inter-disciplinary dialogue
design principles
Design principles
  • Object Oriented Programming
  • Different elements of system are treated as “objects”, e.g. stocks, fleets
  • Each object stores data and has functions that act on that data
  • Objects can be linked together to create simulations
  • Lego blocks
  • Learning curve: trade-off between flexibility and simplicity
  • Uses R – inbuilt graphical and statistical routines

  • http://flr-project.org
the flr initiative1
The FLR initiative
  • Source code under version control (CVS)
the flr initiative2
The FLR initiative
  • Packages available for installation
the flr initiative3
The FLR initiative
  • Main package: FLCore
    • Main classes and functions
  • Collection of secondary packages
    • FLAssess
    • FLEDA
  • What’s in a package?
    • R code for all classes, methods and functions
    • Help pages for each of them
    • Examples and datasets
    • Test scripts
the flr initiative4
The FLR initiative
  • Tutorials and documentation
the flr initiative5
The FLR initiative
  • Work funded by a number of EU projects (FEMS, COMMIT, EFIMAS, Fisboat, …)
  • Core team
    • Maintenance & development of main packages
    • Release of official versions
    • Testing of submitted packages
in brief
In brief
  • Openness & collaboration
  • Lingua franca
  • Bridging the gap between users and developers
  • Learning and working with other disciplines
