چکیده مقاله:

The railway transportation planning under the fuzzy environment is investigated in this paper. As a main result, a new modeling method, called minimum risk chance-constrained model, is presented based on the credibility measure. For the convenience ofs olving the mathematical model, the crisp equivalents ofc hance functions are analyzed under the condition that the involved fuzzy parameters are trapezoidal fuzzy variables. An approximate model is also constructed for the problem based on an improved discretization method for fuzzy variables and the relevant convergence theorems. To obtain an approximate solution, a tabu search algorithm is designed for the presented model. Finally, some numerical experiments are performed to show the applications ofthe model and the algorithm.

A Fuzzy Model for a Railway-Planning Problem

This paper discusses the issue of how to solve multi-criteria decision making (MCDM) problems by applying fuzzy logic. Multicriteria decision-making problems often involve a complex decision process in which multiple requirements and fuzzy conditions have to be taken into consideration simultaneously. Fuzzy set theory provides the mathematical technique for the systematic handling of imprecise ...

Electromagnetism-like Algorithms for The Fuzzy Fixed Charge Transportation Problem

In this paper, we consider the fuzzy fixed-charge transportation problem (FFCTP). Both of fixed and transportation cost are fuzzy numbers. Contrary to previous works, Electromagnetism-like Algorithms (EM) is firstly proposed in this research area to solve the problem. Three types of EM; original EM, revised EM, and hybrid EM are firstly employed for the given problem. The latter is being firstl...

A Grey Transportation Problem in Fuzzy Environment

In classical transport models, it is always assumed that parameters such as the distance from each supply node to each demand node or the cost of transferring goods from one node to another, as well as quantities such as supply and demand are definite and definite amounts. But in real matters, considering these assumptions is not logical. On the other hand, there may be a real problem in mathem...
