Item Brief Overview of Selected Research Directions and Applications of Process Mining in KRaKEn Research Group(Wydawnictwo Politechniki Łódzkiej, 2023) Kluza, Krzysztof; Zaremba, Mateusz; Sepioło, Dominik; Wiśniewski, Piotr; Adrian, Weronika T.; Gaudio, Maria Teresa; Jemioło, Paweł; Adrian, Marek; Jobczyk, Krystian; Ślażyński, Mateusz; Stachuta-Terlecka, Bernadetta; Ligęza, AntoniProcess mining allows for exploring processes using data from event logs. By providing insights into how processes are actually executed, rather than how they are supposed to be executed, process mining can be used for optimizing business processes and improving organizational efficiency. In this exploratory paper, we report on selected research threads related to process mining carried out within KRaKEn Research Group at AGH University of Science and Technology. We introduce a collection of initial ideas that require further exploration. Our research threads are concerned with the use of process mining techniques 1) for discovering processes from unstructured data, specifically text from e-mails, 2) for explaining black-box machine learning models, using process models as a global explanation, and 3) for analyzing data from different food industry systems to identify inefficiencies and provide recommendations for improvement.Item Using Security Games against Wild Dumping Sites(Wydawnictwo Politechniki Łódzkiej, 2023) Adrian, Marek; Markiewicz, JerzySeveral types of criminal activity can by reduced, or prevented, by randomly patrolling areas where it could take place. However, man-made schedules tend to have hidden patterns, which reduces their effectiveness. Thus in several cases game theory has been used to achieve true randomness, while minimizing the potential gain of any hostile entity. Building on this approach we propose a model for creating random schedules for placing cameras to prevent creation of wild dumping sites. While the model is constructed specifically to deal with this particular problem, it can be easily used to plan other schedules involving roads and traffic.
