“…For implementation purposes, an enhanced genetic algorithm (GA) is developed and implemented. Yaghini et al [3] developed a hybrid technique to solve a mathematical model for train makeup planning with fuzzy costs in an Iranian railway system. In fact, they developed a network design model that considers a fixed-charge situation with capacity limitations and multiple commodities.…”

“…Thus, one criteria to the maximization of the customers' satisfaction level and minimization of the costs is to assume maximizing trains in terms of the total frequencies, minimizing yard activities in terms of the total quantity of the action of shunting kind, and minimizing the train underutilization. This is currently missing from the literature (see for example [3][4]); basically, minimization of variable and fixed costs is common in the current literature. In addition, all the required constraints associated with train formation problem is not considered in the current stream of research.…”

“…Railway enjoys significant advantages to other methods of transportation because it is able to respond to freight demand in bigger distances in terms of length as demanded with a higher safety degree [3]. Empirical findings based on indicators and performances show the concern for the operational optimization of a railway network based on important objectives, such as economy, efficiency and customer satisfaction.…”

Abstract. Train formation planning faces two types of challenges; namely, the determination of the quantity of cargo trains run known as the frequency of cargo trains and the formation of desired allocations of demands to a freight train. To investigate the issues of train makeup and train routing simultaneously, this multiobjective model optimizes the total profit, satisfaction level of customers, yard activities in terms of the total size of a shunting operation, and underutilized train capacity. It also considers the guarantee for the yard-demand balance of flow, maximum and minimum limitations for the length of trains, maximum yard limitation for train formation, maximum yard limitation for operations related to shunting, maximum limitation for the train capacity, and upper limit of the capacity of each arc in passing trains. In this paper, a goal programming approach and an Lp norm method are applied to the problem. Furthermore, a simulated annealing (SA) algorithm is designed. Some test problems are also carried out via simulation and solved using the SA algorithm. Furthermore, a sample investigation is carried out in a railway company in Iran. The findings show the capability and performance of the proposed approach to solve the problems in a real rail network.

Purpose. The research aims at the analysis of the possibility of using in the development of one-group train formation plan the criterion, which allows to consider the costs associated with the movement of cars and locomotives. Methodology. The existing methods for development of train formation plan and current directions of its optimization are analyzed. The formulas for calculating the cost-saving criterion for running cars and locomotives in through-trains have been developed. Findings. The dependence between the service speed and the category of train was analyzed on the examples of railway sections of the Belarusian Railways. The obtained results allowed to conclude that, in general, the service speed of through-trains is higher than that of local trains. At the same time, the traffic intensity and section capacity affect the difference between the service speeds of trains belonging to the different categories. The one-group train formation plan was developed using the traditional methods and the proposed criterion on the example of the railway direction, where four marshalling yards are located. The use of the proposed methodology for the development of train formation plan can provide significant savings in operating costs due to the acceleration of the passing of the car through the railway sections. Originality. The use of the additional parameter in the development of train formation plan-«the criterion of cost saving when running of rolling stock in through-trains»is proposed. It is shown that the application of this criterion makes it possible to substantiate the creation of separate assignments of some car-streams, while these car-streams would be considered as unprofitable, when using traditional methods of the calculation of train formation plan. The authors analyzed the influence of such factors as the train composition, the length of the railway section and the car traffic volume on the cost savings by using the proposed criterion. Practical value. The obtained results can be used in the development of the train formation plan, which will save the operating costs connected with the movement of cars and locomotives.
