Free and Open-Source Software for sustainable analysis in logistics systems design

The objective of this paper is to demonstrate how calculations of greenhouse gas emissions from transport in logistics systems can be analysed with Discrete Event Simulation models. For this, modelling was performed by considering the discrete aspects associated with transport systems with the continuous component of the carbon monoxide emissions from the fleet. The simulation models were constructed with the free and open-source software Ururau. The simulations searched to compare trade-offs of economic and environmental variables, in contrast to what is usually done in these types of systems, such as comparing economic variables with inventory variables. The results indicated that there is no direct relationship of proportionality between, for example, the delivery time and the total emissions produced by trucks.
