1. A multiobjective metaheuristic approach for the integrated vehicle and crew scheduling
AbstractThe integrated vehicle and crew scheduling problem is a hard Combinatorial Optimization problem widely studied over the years. Taking into consideration the range of variables related to the planning process of vehicles and drivers, there are several practical characteristics of the problem that are not reflected in the solutions generated computatio

2. Airline crew scheduling in the Brazilian context. / Programação de tripulantes de aeronaves no contexto brasileiro.
This master of science research treats the Crew Scheduling Problem (CSP), as part of the airlines operational planning. The main aim of the CSP is to assign a set of tasks to crew members, considering the labor regulations, safety rules and policies of companies, such that the crew cost is minimal. The CSP is divided into two subproblems, solved sequentially

3. Método de geração de colunas e meta-heurísticas para alocação de tripulação
In a typical crew scheduling problem, for each crew member is assigned a set of trips (a duty) to be performed. The objective is to select the duties such as the total operational cost is minimized, and no trip is left uncovered. Although there are some constraints about how the trips may be combined in a feasible duty, the total number of feasible duties is

4. Heuristics based on variable neighborhood search for the simultaneously vehicle crew scheduling problem in urban transport by bus. / Heurísticas baseadas em busca em vizinhança variável para o problema de programação integrada de veículos e tripulações no transporte coletivo urbano por ônibus.
Na maioria das cidades brasileiras, o ônibus é o principal, senão o único meio de transporte público de passageiros, atendendo àqueles que não possuem carro, mas também contribuindo para reduzir os congestionamentos e, dessa forma, melhorando a qualidade de vida. A fim de incentivar a sua utilização em muitas cidades, inúmeras medidas devem ser to

5. Novas heurísticas para o problema de escalonamento de atripulações / New heuristics to crew scheduling problem
O problema de escalonamento de tripula¸coes consiste na atribui¸cao da tarefa de condu¸cao dos ve´ýculos `as tripula¸coes, de tal forma que todas as viagens realizadas por uma empresa sejam executadas com o menor custo poss´ývel. Esse processo ´e uma etapa de fundamental importancia no planejamento das opera¸coes para uma empresa do setor de transp

6. New heuristics to crew scheduling problem / Novas heurísticas para o problema de escalonamento de atripulações
The crew scheduling problem consists in attributing to the crews the job of driving vehicles, in such a way that trips of dierent lines assisted by a company are executed with the smallest possible cost. This process is of fundamental importance in planning the operations for the public transportation sector and belongs to a class of dicult problems. Several

7. Problemas de escalonamento no transporte coletivo : programação por restrições e outras tecnicas
This dissertation aimed at studying and solving a real world crew management problem. The problem considered arises from the daily operation of an urban transit bus company that serves the metropolitan area of the city of Belo Horizonte, in Brazil. Due to its intrinsic complexity, the problem is usualIy divided in two distinct subproblems, namely: crew sched
