Resumen
Concepts for city logistics require the cooperation between several types of stakeholders. As different stakeholder types have different objectives and different decision spaces, we suggest a top-level qualitative approach (system thinking) to model the interdependencies of the different factors which are influenced by these stakeholder decisions. We also suggest using this qualitative system thinking model as a meta-structure for further quantitative sub-models (as e.g. system dynamics models). We present a methodological approach to create such a meta-structure (i.e. a system thinking model) and give an example on how this meta-structure can be expanded by quantitative sub-models.
