The cities’ makers have to build more sustainable, more liveable, and more efficient cities. Accountability of their choice is growing and conventional way to do is showing limits. Cities are highly systemic system and digital software, in particular, Digital Making Decision Software offer disruptive solution to assess different scenarios on economic point of view but also on environmental, quality of life, and extrafinancial Kpi. This chapter presents the project MUG, located in the Gerland district of Metropole de Lyon (France). The main objective aimed at building digital twin of the Lyon city (with more than 140 datasets) and to able cities maker to elaborate and test scenarios of urban development (road, public transportation, urban project, infrastructures, building, etc.) based on coupled models (20+). The city consists in systems (population, housing, transport, economy, networks of water, energy, waste production and treatment, etc.) interacting together. The presented approach is based on the comparison of scenarios from now to 2040 to help the decision-maker to take the best strategic decision for their cities. |
