Large-Scale Decision-Making via Small Group Interactions: the Importance of Triads1
نویسندگان
چکیده
We study a framework for large-scale decision-making through small group interactions. In this framework, a crowd of participants interact with each other through a sequence of small group interactions, the composition of which are chosen by an algorithm designer, or in some settings, by nature. We consider the problem of finding the wisdom of the crowd, which we take to be the generalized median, in two settings: opinion formation and strategic bargaining. In both cases, we find a significant di↵erence between groups of two and three. When the small groups are of size two, we find that there is no sequence of pairwise interactions which can always converge to a non-trivial approximation of the generalized median so long as the small group interactions satisfy a natural property we call local consistency. This holds even in the simple case when participants come

A New Compromise Decision-making Model based on TOPSIS and VIKOR for Solving Multi-objective Large-scale Programming Problems with a Block Angular Structure under Uncertainty
This paper proposes a compromise model, based on a new method, to solve the multi-objective large-scale linear programming (MOLSLP) problems with block angular structure involving fuzzy parameters. The problem involves fuzzy parameters in the objective functions and constraints. In this compromise programming method, two concepts are considered simultaneously. First of them is that the optimal ...
متن کاملA Fuzzy Decision-Making Methodology for Risk Response Planning in Large-Scale Projects
Risk response planning is one of the main phases in the project risk management and has major impacts on the success of a large-scale project. Since projects are unique, and risks are dynamic through the life of the projects, it is necessary to formulate responses of the important risks. The conventional approaches tend to be less effective in dealing with the impreciseness of risk response p...

متن کاملSustainability, Sustainable Livelihoods, Climate Risks, Small Scale -Farming
Farmers frequently cope with risks due to the uncertainty of climatic conditions. Population growth, changes in agricultural policies, environmental regulations and the degradation of natural resources such as soil and water also present farmers with numerous challenges. Although farmers have experience in coping with a certain degree of uncertainty, increased climate variability and changes ma...
