    Rail mounted gantry crane (RMGC) scheduling is important in reducing makespan of handling operation and improving container handling efficiency. In this paper, we present an RMGC scheduling optimization model, whose objective is to determine an optimization handling sequence in order to minimize RMGC idle load time in handling tasks. An ant colony optimization is proposed to obtain near optimal solutions. Computational experiments on a specific railway container terminal are conducted to illustrate the proposed model and solution algorithm. The results show that the proposed method is effective in reducing the idle load time of RMGC

    ABSTRACT The article is devoted to development of a model for substantiating a region’s need for containerization of cargo transportation. The model includes two interrelated elements: a method for substantiating container suitability for cargoes and an imitation algorithm for planning of the region’s need for containerization. The planning of the need for containerization links the demand of enterprises for transportation (taking into account the levels of product container suitability) and the available resources of the container transport system (terminals, container fleet, rolling stock). Further development of the model assumes assessment of costs and benefits of the region from development of the container system. Verification of the simulation model at the example of Sverdlovsk region demonstrates its efficiency and adequacy of reality. Keywords: container transportation, containerization, container suitability of cargo, social and economic system of the region, development of the region, resources, simulation model, organization of interaction.ΠŸΠΎΠ»Π½Ρ‹ΠΉ тСкст Π½Π° Π°Π½Π³Π». языкС находится Π² ΠΏΡ€ΠΈΠ»Π°Π³Π°Π΅ΠΌΠΎΠΌ Ρ„Π°ΠΉΠ»Π΅ ΠŸΠ”Π€ (Π°Π½Π³Π». вСрсия слСдуСт послС русской вСрсии).Π‘Ρ‚Π°Ρ‚ΡŒΡ посвящСна Ρ€Π°Π·Ρ€Π°Π±ΠΎΡ‚ΠΊΠ΅ ΠΌΠΎΠ΄Π΅Π»ΠΈ обоснования потрСбности Ρ€Π΅Π³ΠΈΠΎΠ½Π° Π² ΠΊΠΎΠ½Ρ‚Π΅ΠΉΠ½Π΅Ρ€ΠΈΠ·Π°Ρ†ΠΈΠΈ Π³Ρ€ΡƒΠ·ΠΎΠ²Ρ‹Ρ… ΠΏΠ΅Ρ€Π΅Π²ΠΎΠ·ΠΎΠΊ.
