Applied models in Demos2k, a semantically well-founded process simulation language, are fundamentally stochastic in their nature. This means that a single run is at best a mere example of the possible range of behaviour - making it necessary to run these models many times over, Monte-Carlo style. This allows us to build a more statistically reliable picture of the overall systems behaviour and how varied it is. In this paper, we introduce DXM - the Demos2k eXperiments Manager - a software application that is designed to help applied analyst/modellers construct and manage repeated experimental simulation runs over a range of parameters. By using our DXM application, analyst/modellers can design their simulation experiments, run them and gather up the results for further analysis. Once analysts have obtained their experimental runs, they can use the DXV tool - Demos2k eXperiments Viewer - to help visually inspect and display these results. A number of Appendices present overall documentation for the current DXM and DXV packages.
