A multimodal multi-criteria route planning (MMRP) system provides an optimal multimodal route from an origin point to a destination point considering two or more criteria in a way this route can be a combination of public and private transportation modes. In this paper, the simulate annealing (SA) and the fuzzy analytical hierarchy process (fuzzy AHP) were combined in order to find this route. ...

The aim of this paper is to present the modeling and validation of a fuzzy inference system to identify electric fault events in real time from the STE (Energy Transportation System) using SOE registries. This system will help us to solve the problem of detecting the beginning of the fault event and extracting the useful information of it. This research is part of the Colciencias – ISA UNAL pro...

This paper aims to study the locomotive routing problem (LRP) which is one of the most important problems in railroad scheduling in view of involving expensive assets and high cost of operating locomotives. This problem is assigning a fleet of locomotives to a network of trains to provide sufficient power to pull them from their origins to destinations by satisfying a rich set of operational con...

Different approaches have been explored in the past to solve fuzzy transportation or shipping problems. The cost of shipping, supply, and demand quantities are all ambiguous a dilemma. Trapezoidal numbers used represent parameters this situation. can be converted into crisp using variety ranking techniques. In paper, we've studied many techniques provided comparison two them. A numerical exampl...

Abstract This article attempts to study cost minimizing multi-objective fractional solid transportation problem with fuzzy coefficients c ˜ i j k r {\tilde{c}}_{ijk}^{r} , supp...

This work develops an interactive fuzzy multi-objective linear programming (i-FMOLP) method for solving the fuzzy multiobjective transportation problems with piecewise linear membership function. The proposed i-FMOLP method aims to simultaneously minimize the total distribution costs and the total delivery time with reference to fuzzy available supply and total budget at each source, and fuzzy ...
