The development of mobile transport on the example of Gdansk Airport

Abstract

The paper presents the development of inter-branch transport based on the example of Gdansk Airport. It was characterized as the Pomeranian Metropolitan Railway as one of the carriers in the forwarding-and-discharging system of this port. The forecasts for the development of transport by the Pomeranian Metropolitan Railway Passengers using the Gdańsk Airport were determined.

A Model for Planning Wagonload Freight Transport Under Relative Uncertainty

“…here, the sum applies to all stations located on the shortest route 𝑀𝑀 𝑖𝑖𝑖𝑖 betwee calculated as a sum of fuzzy numbers. A sum of two (L-R) fuzzy intervals 𝑀𝑀 = (𝑚𝑚, 𝑚𝑚, 𝛼𝛼, 𝛽𝛽) 𝐿𝐿𝐿𝐿 and 𝑁𝑁 = (𝑛𝑛, 𝑛𝑛, 𝛾𝛾, 𝛿𝛿) 𝐿𝐿𝐿𝐿 [1,3,4,5]: 𝑀𝑀 + 𝑁𝑁 = (𝑚𝑚 + 𝑛𝑛, 𝑚𝑚 + 𝑛𝑛, 𝛼𝛼 + 𝛾𝛾, 𝛽𝛽 + 𝛿𝛿) 𝐿𝐿𝐿𝐿 . Given this, savings movement of one wagon, without processing, when the OD pair (𝑖𝑖, 𝑗𝑗) is branch (L-R) fuzzy interval.…”

“…here, the sum applies to all stations located on the shortest route 𝑀𝑀 𝑖𝑖𝑖𝑖 between stations i and j, and is calculated as a sum of fuzzy numbers. A sum of two (L-R) fuzzy intervals 𝑀𝑀 = (𝑚𝑚, 𝑚𝑚, 𝛼𝛼, 𝛽𝛽) 𝐿𝐿𝐿𝐿 and 𝑁𝑁 = (𝑛𝑛, 𝑛𝑛, 𝛾𝛾, 𝛿𝛿) 𝐿𝐿𝐿𝐿 is of the following form [1,3,4,5]: 𝑀𝑀 + 𝑁𝑁 = (𝑚𝑚 + 𝑛𝑛, 𝑚𝑚 + 𝑛𝑛, 𝛼𝛼 + 𝛾𝛾, 𝛽𝛽 + 𝛿𝛿) 𝐿𝐿𝐿𝐿 . Given this, savings 𝑇𝑇 𝑖𝑖𝑖𝑖 associated with the movement of one wagon, without processing, when the OD pair (𝑖𝑖, 𝑗𝑗) is branched off, also constitute an (L-R) fuzzy interval.…”

“…Formulated in this way, vertex 1 of Fig. 4 contains the following OD pairs (1,3), (1,4), (1,5), (1,6), (2,4), (2,5), (2,6), (3,5), (3,6), (4,6).…”
