"Out of all the OS DES projects we reviewed, JaamSim is the one with the most impressive 3D user interface that can compete against COTS DES software. [...] The fact that a non-expert user can just download and test the software in a few minutes is something that is a scarce attribute in OS projects and especially in the DES domain. [...] It is the only tool we found that is clearly industry driven [...] and this may have led to more consistent motivation and funding."[2]
"JaamSim provides everything which is necessary to model typical planning tasks in production and logistics and proves as a real alternative to commercial DES tools."[3]
JaamSim is free open-source software.[4] [5]
