Macroscopes: models for collective decision making [article]

Subramanian Ramamoorthy and András Z. Salamon and Rahul Santhanam
2012 arXiv   pre-print
We introduce a new model of collective decision making, when a global decision needs to be made but the parties only possess partial information, and are unwilling (or unable) to first create a globalcomposite  ...  We illustrate the computational problem inherent in real-world collective decision making processes using results for specific functions, involving detecting a change in state (constant and step functions  ...  INTRODUCTION We consider collective decision making processes such as a market that acts as a central mechanism for coordinating the actions of autonomous participants.  ...

Positive Macroscopic Approximation for Fast Attribute Reduction

Zheng-Cai Lu, Zheng Qin, Qiao Jing, Lai-Xiang Shan
2013 Journal of Applied Mathematics  
Most of them are based on the model that the approximation of all the target concepts associated with a decision system is dividable into that of a single target concept represented by a pair of definable  ...  This paper proposes a novel model called macroscopic approximation, considering all the target concepts as an indivisible whole to be approximated by rough set boundary region derived from inconsistent  ...  For convenience, this model is called microcosmic approximation.  ...

Vision-based macroscopic pedestrian models

Pierre Degond, Cécile Appert-Rolland, Julien Pettré, Guy Theraulaz
2013 Kinetic and Related Models  
We propose a hierarchy of kinetic and macroscopic models for a system consisting of a large number of interacting pedestrians.  ...  A mean-field kinetic model is derived. Then, three different macroscopic continuum models are proposed.  ...  The macroscopic model with monokinetic closure is obtained by collecting (4.5), (4.6), (4.7).  ...

Route Choice-based Socio-Technical Macroscopic Traffic Model [article]

Tanushree Roy, Satadru Dey
2021 arXiv   pre-print
Essentially, such model provides a framework for capturing the Cyber-Physical-Social coupling in smart transportation systems.  ...  However, most existing macroscopic traffic models are typically concerned with driving behavior and do not incorporate human route choice behavior models in their formulation.  ...  Thereafter, a logit model is used to to predict the probability of an outcome. This enables us to capture the probabilistic nature of human decision making [26] .  ...

A Nation-wide Macroscopic Freight Traffic Model

Stephan Müller, Axel Wolfermann, Stefan Huber
2012 Procedia - Social and Behavioral Sciences  
The model is developed as a 6-Step-Model for the area of Germany for the spatial level of NUTS 1. It also links with all European countries as aggregated traffic zones (NUTS 0).  ...  However, there is still no established standard for dedicated commercial traffic models, like there is in private traffic.  ...  The authors express their gratitude to all their colleagues involved in data preparation and computational realisation of the model.  ...

Agent-Based and Macroscopic Modeling of the Complex Socio-Economic Systems

Aleksejus Kononovičius, Valentas Daniūnas
2013 Social Technologies  
Yet in order for an agent-based model to be useful it should also be analytically tractable, possess a macroscopic treatment (Cristelli et al, 2012).  ...  These papers share the idea that agent-based modeling is essential for the better understanding of the complex socio-economic systems and consequently better policy making.  ...  The mechanics behind the collective decision making in the agent-based herding model was discussed in the previous sections and should be clear.  ...
