This article introduces a novel methodology for web based distribution of simulation experiments. The approach is related to themes such as web based applications, cloud computing or applications as a service, which have been recurring topics in scientific papers for years. The methodology is based on automatic model generation, initialization, and result analysis under usage of the CMSD standard. All user interactions are performed in web based user interfaces. Of special importance is that different simulations tools can be used in parallel without any additional effort. Furthermore the simulation tool actually used is transparent to the user. The applicability of our methodology is demonstrated for different production scenarios.
