@orlenyslp I see that the main function build_fuzzy_calendars discovers not only fuzzy calendars, but the full set of simulation parameters:

    simulation_params = {
        "resource_profiles": build_resource_profiles(p_info),
        "arrival_time_distribution": distribution_to_json(arrival_dist),
        "arrival_time_calendar": arrival_calend.to_json(),
        "gateway_branching_probabilities": gateway_branching_to_json(gateways_branching),
        "task_resource_distribution": processing_times_json(res_task_distr, p_info.task_resources, p_info.bpmn_graph),
        "resource_calendars": join_fuzzy_calendar_intervals(p_info.fuzzy_calendars, p_info.i_size),
        "granule_size": {"value": i_size_minutes, "time_unit": "MINUTES"},
    }

I have a couple of questions because of that:

1. Is only resource_calendars the new thing here? Or format of other parameters has also changed?
2. Does Prosimos already support running this new parameters?

The new components in the model are "task_resource_distribution" and "resource_calendars", as the processing times are also calculated according to the fuzzu_calendars discovered. The other components, "resource_profiles", "arrival_time_distribution", "arrival_time_calendar", and "gateway_branching_probabilities" uses the same discovery functions as the crisp model. Prosimos, already support them but that implementation is in the branch "fuzzy_calendars" in Prosimos. I am still working on merging it to the main branch, but there were several conflicts that I am still fixing. However, I think I will be done with it by tomorrow.
