- The second is increasing ability to refine the workings of simulation software through the use of open source development techniques (see Figure 1).
As the Community moves along these stages, the tasks involved become increasingly difficult.
The starting point is current practice, here called Expertexpert-Prepared Modelsprepared models, in which a small cadre group of expert modelers experts builds a simulation model and releases the results of its model runs in presentations or publications.
The five stages that go beyond Expert Prepared Models expert prepared models and move toward the vision of radically open modeling are:
1. Live Interactive Use of a Single Model
2. Sharing Multiple Runs of a Single Model
4. Model Disaggregation and Swapping out of Modules
5. Massive Collaborative Model Development and Analysis of Runs
