Characteristics of Effective Freight Models

The paper postulates four main characteristics that are important for effective modeling: (1) An effective model is focused on producing an output that someone wants and knows how to use; (2) An effective model includes the important variables that describe how the system works and represents their interactions clearly and correctly; (3) An effective model operates in a way that is verifiable and understandable; and (4) An effective model is based on data that can be provided, so that it can be calibrated and tested. These ideas are discussed in greater detail in the context of freight transportation system models.
