This dataset contains 4 models of increasing sizes and a number of event logs generated through the PLG2 tool. The event logs are grouped in three categories, according to the average number of events in a trace with the same timestamps (referred to as isochronous groups of events). For each isochronous category and for each of the 4 models, 4 event logs are present, with no deviations and with 10%, 20%, 30% of event's swapping frequency)
