The dimensioning of logistics operations has always been a challenge for most companies. Knowing how much equipment and/or human resources will be needed to support a new operation (or the increased demand of a consolidated operation) is not a trivial problem and easy to calculate. Several variables contribute to this calculation difficulty, such as the randomness of demand and productivity of resources. In this challenging context, simulation emerges as a possible alternative for an effective dimensioning of operations.

Simulation models try to replicate the real operation to be implemented through specialized software. These models consider both demand and resource productivity as statistical probability curves, that is, there is an average and an expected deviation for each activity. In this way, fluctuations typical of real operations are considered in the model and the recommended final sizing also takes these possible deviations into account.
Another advantage of simulation models is the possibility of visually seeing the operation, which can consider different products and activities. In the same workstation, many different demands can pass with different processing times, which makes the sizing calculation more complex using other mathematical techniques, such as queuing theory. In addition, in the simulation software there is the possibility of visualizing the operation taking place in real time, as well as the waiting queues and idleness of the workstations.
Some common applications of simulation models already carried out by ILOS are in container terminals (https://ilos.com.br/web/planejamento-de-capacidade-num-terminal-de-conteineres-via-simulacao-um-estudo-de-caso/) and fuel distribution (https://ilos.com.br/web/aplicacao-da-simulacao-no-dimensionamento-de-bases-de-distribuicao-de-combustiveis-2/). However, the simulation is applicable to any manufacturing or administrative operation in any economic sector.
And does your company have any plans to expand or open a new operation in the short or medium term? An effective dimensioning of resources can be fundamental for the success of this enterprise.
