 - The DES and SD models are taken as input.
 - For the ease of use and performing experiments with your desired process, the following supports are provided:
 - To generate a CPN model of your process and the corresponding SML file using an event log, you can use the following link, in case of any specific scenario you need to change the process model in the CPN Tools. The link only generates a CPN model based on the given event log, further desired changes should be done by the user.

 - In case you want to generate your SD Logs and SD models, this tool supports you https://github.com/mbafrani/PMSD
 - Note that you need to make sure that there are common variables names, e.g., service time, arrival rate, ..., are in both models that can be updated.

 Process mining field has been enriched with multiple techniques and tools for different purposes. However, these techniques are mostly 'backward-looking'. 
 'PMSD' is a web application tool that supports forward-looking simulation techniques. It transforms the event data and process mining results into a simulation model.
