Zapewnienie ustalonych parametrów jakościowych dla transmisji w sieciach komputerowych jest bardzo istotnym zadaniem. Jak pokazały wcześniejsze badania [3,6] koncepcja Pay&Require może być wykorzystana do zapewniania wymaganej jakości transmisji. Aby uzyskać wyniki niezależne od konfiguracji sieci testowej, tj. urządzeń sieciowych, łączy i innych elementów, należało przeprowadzić badania z wykorzystaniem powszechnie stosowanego symulatora sieciowego NS3. Badania symulacyjne przeprowadzono dla kilku topologii sieci.

Ensuring required parameters of transmission quality in computer networks is a very important issue. As previous studies have shown [3,6], the Pay&Require concept can be used to ensure required quality of transmission. To obtain results independent of the test network configuration i.e. network devices, links and other elements we conducted studies using well-known network simulator NS3. The simulation investigations were carried for several networks with different topologies.

An important aspect of the simulation modelling process is sensitivity analysis. In this process, agent-based simulations often require analysis of structurally different parameter specifications – the parameters can be represented as objects and the object-oriented simulation configuration leads to nesting of simulation parameters. The nested parameters are naturally represented as a tree rather than a flat structure. The standard tools supporting multi-agent simulations only allow only the representation of the parameter space as a Cartesian product of possible parameter values. Consequently, their application for the required tree representation is limited. In this paper an approach to tree parameter space representation is introduced with an XML-based language. Furthermore, we propose a set of tools that allows one to manage parameterization of the simulation experiment independently of the simulation model.

If several distributed and disparate computer resources exist, many of which have been created for different and diverse reasons, and several large scale computing challenges also exist with similar diversity in their backgrounds, then one problem which arises in trying to assemble enough of these resources to address such challenges is the need to align and accommodate the different motivations and objectives which may lie behind the existence of both the resources and the challenges. Software agents are offered as a mainstream technology for modelling the types of collaborations and relationships needed to do this. As an initial step towards forming such relationships, agents need a mechanism to consider social and economic backgrounds. This paper explores addressing social and economic differences using a combination of textual descriptions known as social profiles and search engine technology, both of which are integrated into an agent technology.

In a grid environment the resource management, task scheduling and also load balancing are essential functionalities provided by software infrastructure. Recently, intelligent agent technology has provided an adaptive and scalable framework for management and scheduling of dynamic resources in the grid environment. In this approach an agent is a representative of a grid resource that is supported by a software system. This paper presents a new agent-based method, called GLBAI, for the improvement of global load balancing. While previous works assume that all existing agents in the environment have identical capabilities, this paper considers different capabilities for different agents. It proposes an agent identifier that indicates the agents capabilities. The agents cooperate with each other to balance workload using a service advertisement and discovery mechanism in which agents capability information are passed in the form of the identifier. Simulation results show that GLBAI reduces application execution time, maximizes resource utilization and offers more efficient load balancing service.

PL

W artykule przedstawiono nową metodę agentową o nazwie GLBAI, do zarządzania zasobami energii w sieci. Metoda ma na celu ulepszenie zbalansowania globalnego obciążenia sieci, poprzez uszeregowanie różnych agentów pod względem ich możliwości zasobowych i nadanie odpowiedniego identyfikatora. Agenci współpracują między sobą w celu zbalansowania obciążenia oraz wykorzystania informacji zawartych w identyfikatorach. Badania symulacyjne wskazują, że system GLBAI redukuje czas wykonania programu, maksymalizuje wykorzystanie zasobów oraz oferuje lepszy zbalansowanie obciążenia.

W pracy przedstawiono system agentowy, który pozwala na monitoring rozproszonych systemów. Każdy agent posiada własną wiedzę na temat możliwych reakcji na zaobserwowane sytuacje, np. awarie. W artykule przedstawiamy koncepcję automatyzacji monitoringu nazwaną SAMM compliant Agent. Jest ona rozszerzeniem systemu SAMM. Do opisu wiedzy użyte zostały zbiory rozmyte, a także reguły, przy czym reguły używane są do określenia prostych czynności, które może wykonać dany agent. W zaimplementowanej wersji reguły służą jako statyczna wiedza, natomiast logika rozmyta została wykorzystana jako główna idea reprezentacji wiedzy w przedstawionych agentach, z których każdy zarządza swoim segmentem wiedzy i może swoją wiedzę przekazywać innym agentom.

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.

The supervision of complex manufacturing systems is handled in this paper. Production lines of manufacturing systems are understood here to be hybrid agents. Such an agent expresses continuous material flow together with a set of imperative discrete operations. In other words, the hybrid agent makes a cooperation of continuous and discrete event devices possible. The results are applied to complex continuous manufacturing system. First Order Hybrid Petri Nets (FOHPN) are utilized in order to model the elementary autonomous hybrid agents. The cooperation of hybrid agents is based on the DES (discrete-event systems) control theory. It is realized by means of DES supervision methods and the agent negotiation is based on place/transition Petri nets (P/T PN). The proposed approach is illustrated in details on the cooperation of hybrid production lines in the real complex manufacturing systems recycling waste plastics into plastic bags. The usefulness and applicability of the approach consists especially in the fact that the procedures in analytical terms can be employed. In such a way the approach turns lucid also in complicated cases.

W oparciu o analizę funkcjonalną zbioru amunicji potwierdzoną analizą strukturalną stwierdzono w artykule, że najczęściej typowymi strukturami niezawodnościowymi obiektów technicznych jakim są środki bojowe, są struktury szeregowe, równoległe i mieszane. W rozważaniach niezawodnościowych wymienionych struktur przyjęto jako podstawę funkcję niezawodności definiowaną jako prawdopodobieństwo zachowania przez amunicję stanu zdatności, podczas wykonywania przez nią określonego zadania w określonym czasie i w określonych warunkach. Uwzględniając czas składowania amunicji w magazynach oddziałów gospodarczych, do oceny poprawności jej funkcjonowania przyjęto zmodyfikowane wartości funkcji niezawodności w postaci wskaźników niezawodnościowych określonych w artykule. Sposób wyznaczania wartości tych wskaźników opisany został w literaturze artykułu, jednakże aby oszacowanie ich było dokładniejsze wskazane jest wyznaczenie przedziałów ufności czyli zadanych z góry poziomów dokładności tych wskaźników. Przedstawiona propozycja metody estymacji wskaźników stanu technicznego amunicji w oparciu o nowy model ocenowy, jest próbą udokładnienia szacowania tych wskaźników, natomiast granice jednostronnego i dwustronnego przedziału ufności przy zadanym poziomie ufności są zobrazowaniem tej metody. Na przykładzie praktycznym przedstawiona metoda obliczania przedziałów ufności dla zwiększonej próbki losowej badanych elementów środków bojowych umożliwia określenie relacji pozwalających wnioskować o tendencjach zmian jakościowych zachodzących w magazynowanych środkach bojowych.

Basing on the functional analysis of ammunition set confirmed by structural analysis it is claimed in this article that most typical reliability stuctures of technical objects such as ammunition, are terrace, parallel and mixed stuctures. In reliability considerations of the mentioned stuctures, the reliability function defined as the probability of maintaining the ammunition fit condition, was accepted as a basis, while performing a particular task by this ammunition in particular time and particular conditions. Taking into consideration the ammunition storage time in economic units storages were assumed for the evaluation its correct functioning modifed values of reliability function in the form of reliability indicators determined in the article. The way of laying down the values of these indicators was described in the sources of the article, however that evaluation in order to make be more thorough, it is recommended to lay down the trust brackets, i. e. assumed precision levels of these indicators. The presented estimation method of technical condition of ammunition indicators on the basis of new evaluation model, is an attempt to refine these indicators estimation, but the limits of one-side and two-side trust brackets at given trust level are the visualisation of this method. On the practical example, the presented method of calculation trust brackets for increased random sample of researched elements of ammunition enables to determine relations which allow deduction about the trends of quality changes taking place in ammunition storages.

Agents play an important role in high level artificial intelligence in such areas as distributed decision support, robot control, computer games, etc. Currently, the most popular high-level agent architectures are based on the belief-desire-intention (BDI) model. BDI agents are usually specified in modal logic. This is efficient for defining event goals. However, defining quantitative goals can be very difficult in many popular formalisms. In this paper we propose a method for expressing quantitative goals by associating partial utility functions with agent’s goals. We propose a modified BDI agent architecture which is loosely based on fuzzy logic. In this architecture, approximation of partial derivatives of those functions enables us to use gradient based optimization algorithms in the intention reconsideration step to weight some action specializations. Using the proposed approach allows us to easily combine quantitative and event goals, and consider them all while planning. This paper also describes a simple language which can be used to elegantly describe generic action libraries in accordance to the proposed model.
