    Agent-based monitoring using fuzzy logic and rules
    (Wydawnictwa AGH, 2011) Funika, Włodzimierz; Szura, Filip; Kitowski, Jacek
    In this paper we present two solutions ofmonitoring automation for distributed systems. We develop this system to automate monitoring of distributes systems. Both solutions are aimed to monitor data storage and web services like web page servers. The first solution implemented in a system called Saude-Net, is an rule-based top level monitoring tool. In this system there are implemented rules which provide conditions which refer to one or more measured values. This system is able to choose the best action for an observed situation, e.g. a failure. It is possible to define more than one rule which relate to the same monitoring resource. The second concept presented in this paper refers to a fuzzy logic agent based approach to network monitoring. It is called SAMM compliant Agent. It is an extension to the Semantic-based Autonomous Monitoring and Management system (SAMM). On the one hand, it uses rules to define simple actions, based on a simple condition and an action description. On the other hand the main knowledge of this solution is defined by fuzzy logic. This system is able to manage and modify its knowledge to better fit to monitored resources. The knowledge in this concept is distributed among all the agents. The agents residing on a different hosts handle their parts ofthe knowledge and are capable to share/exchange them.

    Kryteria prawdy i użyteczności informacji w modelach zarządzania w warunkach niepewności i ryzyka
    (Wydawnictwa AGH, 2005) Gil, Zdzisław
    In this paper there is presented the model of making decisions in the company where its condisions is unstable. Then the decidend is forced to make quick decisions based on information not always reliable and complete. There is a conflict between effective managment in the case of a risk and an aversion to some action within a group of decidends which causes a risk. This paper presents some suggestions how to mitigate the conflict.

    Multi-criteria simulation model for determining dengue outbreaks
    (Wydawnictwa AGH, 2020) Jakubowski, Piotr; Erandi, Hasitha; Mahasinghe, Anuradha; Perera, Sanjeewa; Ameljańczyk, Andrzej
    In this study, we develop a multi-criteria model to identify dengue outbreak periods. To validate the model, we performed a simulation using dengue transmission-related data in Sri Lanka’s Western Province. Our results indicated that the developed model can be used to predict a dengue outbreak situation in a given region up to one month in advance.

    Podejmowanie decyzji z wykorzystaniem zbiorów rozmytych typu 2
    (Wydawnictwa AGH, 2006) Rutkowski, Leszek
    In the paper type 2 fuzzy sets are presented. The intersection operation and type reduction operation are explained. An application of type 2 fuzzy sets to decision making systems is given.
