Social choice theory is a theoretical framework for analysis of combining individual preferences, interests, or welfares to reach a collective decision or social welfare in some sense. We introduce a new criterion for social choice protocols called ”social disappointment”. Social disappointment happens when the outcome of a voting system occurs for those alternatives which are at the end of at ...

The optimal aggregation of (expert) opinion has been a focus of much research, and there is a clear resemblance to the problem of the optimal combination of multiple items or tests (e.g. Meehl, 1999). For binary choice situations with a correct alternative, it has been shown that a weighted sum of individual choices is the optimal aggregation rule, where the weights proportional to the odds of ...

Computational social choice is a new discipline currently emerging at the interface of social choice theory and computer science. It is concerned with the application of computational techniques to the study of social choice mechanisms, and with the integration of social choice paradigms into computing. The first international workshop specifically dedicated to this topic took place in December...

Discrete choice models have played an important role in transportation modeling for the last 25 years. They are namely used to provide a detailed representation of the complex aspects of transportation demand, based on strong theoretical justiications. Moreover, several packages and tools are available to help practionners using these models for real applications, making discrete choice models ...

e-Social Science will transform not only how social researchers do their work, but also what they will discover, with whom they will collaborate, how they will share work, how they will report their findings, and what know-how they will require. Emerging technologies, such as the Grid and advanced Internet and Web developments, will reshape not only how researchers do what they do, but also the...

To explore the relation between mathematical models and reality, four different levels of reality are distinguished: observer-independent reality (to which there is no direct access), personal reality, social reality and mathematical/formal reality. The concepts of personal and social reality are strongly inspired by constructivist ideas. Mathematical reality is social as well, but constructed ...

In the context of the arrival of electric vehicles on the car market, new mathematical models are needed to understand and predict the impact on the market shares. This research provides a comprehensive methodology to forecast the demand of a technology which is not widespread yet, such as electric cars. It aims at providing contributions regarding three issues related to the prediction of the ...

In this paper, we focuse on the role of a dynamic model in the control of the motions of a manipulator. Although this question has been the object of many works for years, it is still often diicult, when designing a controller for an industrial manipulator, to predict the costs and the expected beneets of a dynamic controller implementation. In this context, the aim of our paper is not to propo...
