The current generation of DES software targets a wide customer base and offers a generalized set of components from which the users can construct a custom simulation model. This has been aided by a wider acceptance of simulation as an analysis tool. These software packages have a graphical interface and data visualization capabilities that improve the ease of use and the overall user experience [36] [37]. This also helps with debugging the simulation. Furthermore, the visualization is helpful for presenting and explaining the simulation results to those who are not familiar with the problem.
