This paper is mainly focused on the development of city rail transport system and network in Nur-Sultan, Kazakhstan. This capital city with population of ca. 1.05 million citizens relies only on buses in the topics of public transport. Unfortunately, these vehicles are not as efficient as needed, because of their capacity. In the rush hours they are often delayed and overcrowded, the 88 bus lines are indirect with complicated detours, therefore complicated and unclear. The high number of buses increases everyday congestions on roads. The city tried to solve these problems by their own ideas -BRT and LRT. The first idea (construction of BRT system) was abandoned and the second one (construction of LRT system) may not work as well as the people of Nur-Sultan could wish and use. In order to improve this situation, the analysis of current situation was made. Based on the results, the conceivable solution was purposedreplacing majority of buses with only 5 tram lines. The usage of trams could lead to lowering the number of buses and cars in the streets, thus making transportation faster, more comfortable and ecological.

While traveling through the cities by public transport, it is important to have enough and quality information about the following lines and transfers between them -especially, while checking-in. Nur-Sultans' public transport vehicles lack the working electronic information panels in their interior. The purpose of this paper was to propose the design of the electronic information panel inside of the buses. The whole screen should inform passengers inside the vehicles while traveling about the current position of the vehicle and possible transfers. It should serve as an alternative to mobile applications. It includes all the positives of inspected systems from other countries and few more like for example: the ability to react on real delays of vehicles and informing passengers about irregularities on the routes. There would be no need to use a smartphone to search for the connections.

“…The Fixed Charge Transportation Problem (FCTP) is an extended form of transportation problem in which a fixed cost, sometimes called a setup cost, is incurred if a distribution variable assumes a nonzero value [1][2][3][4][5], this problem is formulated and solved as a mixed integer network programming problem [6].…”

This paper considers a fixed-charge transportation problem with fuzzy shipping costs. Whereas the shipping costs of routes are fuzzy intervals, with increasing linear membership functions, fixed costs, supplies, and demands are deterministic numbers. By defining a membership function associated with the objective values and utilizing Bellman-Zadeh’s max-min criterion instead of the main problem, a new crisp nonlinear mixed-integer programming problem is formulated. To solve this non-linear programming problem, at first, we find optimality conditions for a feasible solution, then, using these optimality conditions, reformulate the non-linear programming problem as a linear mixed-integer fractional programming problem, and finally transform the fractional programming problem as a mixed-integer linear programming problem, which can be solved using the existence methods. An illustrative example is solved to explain the presented details.
