In the context of logistics and transportation, this paper discusses how simheuristics can be extended by adding a fuzzy layer that allows us to deal with complex optimization problems both stochastic uncertainty. This hybrid approach combines simulation, metaheuristics, logic generate near-optimal solutions large scale NP-hard typically arise in many transportation activities, including vehicl...

This paper proposes a new approach to solve the trapezoidal fuzzy unbalanced transportation problem. The proposed method is very efficient in terms of computation. The algorithm of this approach is presented, and explained briefly. Finally, a numerical example is described in the paper to show its efficiency.

this paper considers the multi-depot vehicle routing problem with time window in which each vehicle starts from a depot and there is no need to return to its primary depot after serving customers. the mathematical model which is developed by new approach aims to minimizing the transportation cost including the travelled distance, the latest and the earliest arrival time penalties. furthermore, ...

—Competitive global markets oblige the firms to reduce their overall costs while maintaining the same customer service level and this can be achieved just through a precise and efficient management of their supply chain network. The Fixed Charge Transportation Problem (FCTP) which is a more comprehensive type of Transportation Problem (TP) has several applications from different aspects in this...

In this paper we pretend to show a new approach to a classical network optimisation problem: the transportation problem. Firstly, allowing the vehicles that can establish routes, and, also, permitting to manage with imprecise or vague information. We propose to use the Fuzzy Sets Theory [9]; [4]; [10], with the aim of being able to handle the uncertainty, which is characteristic of decisionmaki...

  Selection of appropriate infrastructure transportation projects such as highways, plays an important role in promotion of transportation systems. Usually in evaluation of transportation projects, because of lack of information or due to long time and high expenditures needed for gathering information, different effective factors are ignored. Thus, in this research, regarding multi criteria na...
