Logistics has developed in parallel with the development of science and technology, productive forces and social relations. As a concept, logistics is associated mainly with the activities necessary to optimize the purchase of products, raw materials and equipment from the supplier to the end user. In order for everything to function with minimal costs, logistics is increasingly being linked with the simulation of real systems. Simulation itself is a process of creating a model of the real system and conducting experiments with models; all to make the behavior of the system more understandable. Besides understanding the real system, simulation is used for the prediction of various problems which need to be resolved in a quick and efficient manner in order to remain competitive on the growing global market. The development of simulation at mid-century enabled an easier display of real problems, and it also created space for more acceptable solutions to these same problems. As time went on, computer simulation programs, which can predict a variety of problems with increasing accuracy and therefore substantially reduce the reaction time needed to resolve them, were created. FlexSim is one of the computer programs whose simple use provides quality predictions for various real problems within the logistics systems. A user, using Flexsim to create quality simulation of the system, can contribute to quality and faster problem solving, thus leaving the logistics company with more time and economic resources for the expansion on the global market.
