Complexity Science–an introduction (and invitation) for actuaries

Recognizing the potential importance of the new field of Complexity Science for the work of actuaries, the Health Section asked Alan Mills to write an introduction to the field. His report includes an overview of the field's key results, detailed instructions for building Complexity Science models, examples of working models for you to run, a review of practical models applicable to the work of actuaries, an extensive literature review, and a discussion of how actuaries can apply Complexity Science in their work.
