Computer processing power has developed to the stage where simulation has become an extremely popular and applicable way of representing real world systems for investigation. For the most part simulation studies as a whole can be long complex projects. Through-out the simulation industry there is a common consensus from available literature that certain steps should be followed to create a credible, successful simulation. While this is well known it appears that these guidelines are more “Do what I say, not as I do,” within the simulation community. In the experience of the author of this project simulation teams and modellers approach their own simulation studies in their own different ways, yet when the simulation study reaches its conclusion a credible simulation still has to be presented to a client or relevant party. For example a simulation modeller may often spend the most time and in turn resources on building the simulation model, yet this model will be next to useless without any documentation relating to the validation of said model. With good documentation being applied through-out a study, to each specific step, it only serves to make the succeeding steps easier to implement. This project highlights and uses the Systems Modelling Language (SysML) as a tool and method to develop diagrams to aid either the team or the modeller. These diagrams can be used as references when adhering to the steps of creating a credible, successful simulation study as well as a graphical support when presenting the entire simulation study to the client or relevant parties involved. This thesis also covers an independent assessment of the generated SYSML diagrams. Importantly when developing a method such as using SYSML as a graphical aid for simulation studies it must be reviewed by interested parties so that the areas that work well can be highlighted as well any areas which lack or need developing.
