An application of power indices for the family of weighted majority games in partition function form

Based on Holler (1982) and Armijos-Toro et al. (2021) we propose two power indices to measure the influence of the players in the class of weighted majority games in partition function form. We compare these new power indices with their original versions on the class of games in characteristic function form. Finally, we use both pairs of power indices for games in partition function form to study the distribution of power in the National Assembly of Ecuador that emerged after the elections of February 7, 2021.

A hybrid heuristic algorithm with application to a graphical interface for vehicle routing optimization in an agricultural cooperative

This work considers the problem of optimize the routes of the vehicles used by a real agricultural cooperative that distributes animal feed among the partners. Because solving the exact model is computationally burdensome, we propose to implement heuristic algorithms. Thus, firstly an initial solution is obtained through an insertion heuristic algorithm. Secondly, we design a simulated annealing algorithm for possible improvements on the initial solution. Finally, we built a graphical interface to quickly and easily interact with the system.
