The Model Life-Cycle

This module has three main objectives that will provide further insight into environmental modeling:

  1. Define the 'model life-cycle'
  2. Explore the stages of a model life-cycle
  3. Introductions to strategies for the development, evaluation, and application of models

The life-cycle of a modelHelpmodelA simplification of reality that is constructed to gain insights into select attributes of a physical, biological, economic, or social system. A formal representation of the behavior of system processes, often in mathematical or statistical terms. The basis can also be physical or conceptual. includes identification of a problem and the subsequent development, evaluation, and application of the model.
