“…Most of the models in the literature either work on improving the efficiency of solving the LAP or attempt to solve the three levels of LAP separately. With the exception of Piu, Kumar, Bierlaire, and Speranza (2015), which aims at partial integration, there exists no model that integrates across the three levels of LAP. Though quite challenging, a linear mathematical model that integrates the strategic, tactical and operational level aspects of LAP could be a promising future research direction.…”

Since the appearance of mechanized rail transport systems in England in the 1820s, the railway has developed to a great extent and has become the primary mode of longdistance land transportation for people as well as for bulk material across the world. What began with steam locomotives, gradually made way for diesel and then to electric engines. Over the past couple of centuries, with the increase in importance of the railway to economy, the complexity of railway networks and consequently the decision-making involved with railway organizations have also increased significantly. With a great deal of decision-making involved in managing different aspects of the railway, every decision made by the management of railway organizations has a profound impact on profitability.

“…The fleet sizing problem is also one of highlighted topics within the transportation area (see [ 9 – 11 ]). Taking the railway transportation as an example, the concept of fleet sizing embodies (but is not limited to) the following problems: the locomotive scheduling problem [ 12 – 15 ], the rolling stock circulation problem [ 16 – 18 ] and the empty car distribution problem [ 19 – 21 ]. Aside from the transportation planning field, the workforce sizing optimization has also been widely applied to other fields in recent years, to name but a few, the manufacturing industry field [ 22 ] and the nurse staffing field [ 23 ].…”

Due to its environmentally sustainable and energy-saving characteristics, railway transportation nowadays plays a fundamental role in delivering passengers and goods. Emerged in the area of transportation planning, the crew (workforce) sizing problem and the crew scheduling problem have been attached great importance by the railway industry and the scientific community. In this paper, we aim to solve the two problems by proposing a novel two-stage optimization approach in the context of the electric multiple units (EMU) depot shunting driver assignment problem. Given a predefined depot shunting schedule, the first stage of the approach focuses on determining an optimal size of shunting drivers. While the second stage is formulated as a bi-objective optimization model, in which we comprehensively consider the objectives of minimizing the total walking distance and maximizing the workload balance. Then we combine the normalized normal constraint method with a modified Pareto filter algorithm to obtain Pareto solutions for the bi-objective optimization problem. Furthermore, we conduct a series of numerical experiments to demonstrate the proposed approach. Based on the computational results, the regression analysis yield a driver size predictor and the sensitivity analysis give some interesting insights that are useful for decision makers.

“…Foram implementadas duas variantes com regras distintas de atualização dos feromônios e comparados os resultados. Piu et al (2015) propõem para a resolução do problema de alocação de locomotivas o conceito de seleção preliminar de blocos (consists), resolvendo um subproblema inicial para definição dos blocos de locomotivas a serem considerados no problema principal. Para tanto, dada uma programação de trens conhecida, dividem o processo de planejamento de alocação de locomotivas em três fases: planejamento, programação e roteamento.…”

“…De acordo com Piu et al (2015) e Premkumar e Ram Kumar (2020) existe escassez de trabalhos onde decisões e restrições de horizontes distintos sejam tratadas simultaneamente, objetivando melhores resultados globais do que aqueles obtidos através de modelos construídos para um único horizonte.…”
