Modeling of a Closed-Loop Maritime Transportation System with Discrete Event Simulation and Multi-Criteria Decision Analysis
نویسندگان
چکیده
The present paper approaches the development and application of a Discrete Event Simulation (DES) model with a Multiple Criteria Decision Analysis (MCDA) tool for the simulation and sizing of a closed-loop maritime transportation system. This system is responsible for the supply of raw materials, especially iron ore, to a steel plant, and its sizing involves the analysis of the transportation fleet and of the storage area for the inputs to the steel making process. This work characterizes the problem, shows the methodology employed and highlights the main results achieved by the simulation. Concomitantly, the choice of the best solution between the simulation results is made based in the application of the MCDA methodology. The main conclusion of the study is that the use of DES combined with MCDA is an efficient way to help decision-making on complex logistics transportations systems.
