Neste problema, considera-se uma vantagem econ?mica quando o caixeiro, viajando em um ve?culo privado, embarca passageiros que passam a dividir as despesas da viagem com ele. O modelo pode representar situa??es reais onde o motorista tem uma rota de visita de cidade predefinida, na qual a cada cidade est? associado um b?nus, sendo demandada a coleta de um valor m?nimo desses b?nus, na fun??o objetivo da variante investigada leva-se em conta a possibilidade da redu??o dos custos do caixeiro embarcando pessoas em seu ve?culo. Um modelo matem?tico, seis algoritmos evolucion?rios, um GRASP e um heur?stico s?o apresentados para o problema. O comportamento dos algoritmos propostos ? analisado em um experimento computacional com 48 inst?ncias. / The Traveling Salesman Problem with Ridesharing and Quota belongs to the class of Quota Traveling Salesman problems. In this problem, it is considered the economic advantage achieved when the salesman, traveling in a private vehicle, gives ride to passengers who share travel expenses with him. The model can represent real situations where a driver programs a route to visit cities, each of which associated with a bonus, with the requirement of collecting a minimum sum of bonuses and taking into account the possibility of reducing costs due to people embarked in his vehicle. A math model, six evolutionary algorithms, a GRASP and one heuristic are presented for the problem addressed. The behavior of the proposed algorithms is analyzed on a computational experiment with 48 instances.
