Abstract for: Tackling the Mess: Causal-Loop Conceptualization of Solid Waste Management Systems through Cross-Impact Analysis

A common first step for building a system dynamics model is the selection of variables. This is one of the most important activities in the construction process because they constitute the building blocks upon which the explanations for complex patterns of behavior are proposed based on the interrelations of those variables. This work aims to present an option to systematically help to guide the selection of key variables integrating quantitative and qualitative analysis. A current project in Colombia that develops a dynamic conceptualization for Solid Waste Management policy-making is used as an example.
