Interactive Optimization With Parallel Coordinates: Exploring Multidimensional Spaces for Decision Support

François Maréchal, Sébastien Cajot, Nils Christian Schüler

Interactive optimization methods are particularly suited for letting human decision makers learn about a problem, while a computer learns about their preferences to generate relevant solutions. For interactive optimization methods to be adopted in practice ...

The optimum is not the goal: Capturing the decision space for the planning of new neighborhoods

François Maréchal, Jessen Page, Sébastien Cajot, Nils Christian Schüler

This article presents the development and application of a methodology that employs optimization not to seek the single or few optimal plan(s) but to provide planners with a systematic overview of their decision space. As urban development projects are not ...

Linking interactive optimization for urban planning with a semantic 3D city model

François Maréchal, Sébastien Cajot, Nils Christian Schüler

The cities in which we live are constantly evolving. The active management of this evolution is referred to as urban planning. The according development process could go in many directions resulting in a large number of potential future scenarios of a city ...

Multicriteria Decisions in Urban Energy System Planning: A Review

François Maréchal, Sébastien Cajot

Urban energy system planning (UESP) is a topic of growing concern for cities in deregulated energy markets, which plan to decrease energy demand, reduce their dependency on fossil fuels, and increase the share of renewable energy sources. UESP being a high ...

Obstacles in energy planning at the urban scale

François Maréchal, Sébastien Cajot

Cities are expected to play a key role in achieving the ambitious energy targets set by the European Union. By looking at opportunities beyond the single building scale, urban planners can significantly contribute to shape energy-efficient and low-carbon c ...

Establishing links for the planning of sustainable districts

François Maréchal, Jessen Page, Sébastien Cajot, Nils Christian Schüler

Cities can play a key role in mitigating climate change impacts, as they represent two thirds of the world’s energy consumption and greenhouse gas emissions. This paper presents a model-based approach to support cities in the challenge of including energy ...
