2. Collaboration. Communication and interaction are one of the essential factors to achieve a successful simulation project.
It is possible to develop environments with coherent Web-based support for collaborative model development where people can communicate with each other from different places to develop the same simulation model over the Web. Such collaboration can include monitoring and debugging with the help from experts . This approach may result in a reduction in simulation model development cost and time, over the use of simulation modelling packages such as Arena and eM-Plant which are only used at a local machine and lack group interaction capability .
3. Licence and deployment models. The tool can be deployed locally, in an intranet setting or over the Internet, regardless of how it has been developed. The possibility exists to tailor the GUI allowing the use of the application on any device with a relevant Web browser installed. New licence models for simulation software have become possible, which is
