MAREA
Opis:
Research background: Managerial scientists use a lot of modelling techniques for business processes. In this paper we are focused on agent-based modelling and simulations, which emerged in the last two decades as a new approach. Autonomous and interacting intelligent agents are able to model and simulate complex systems in the business sphere. With the use of agent-based modelling and simulations we are able to understand how macro level outcomes are affected by micro level processes and vice versa. Purpose of the article: The purpose of the paper is to introduce recent development in the area of agent-based modelling and simulations focused on the business domain. Managers often have to make difficult decisions under the uncertainty and high risks. Agent-based modelling can provide powerful tools for lowering those risks through a possibility of running experiments, which is normally impossible in economics. In the second part we want to support the usefulness of agent-based simulations with our own simulations. Methods: The method used in this article is an agent-based simulation in a multi-agent system. We use a framework called MAREA. It is a simulation environment with integrated ERP system based on REA ontology. Our simulation model is based on a retail company that sells electronics. For simplicity, in our setup we trade with computer cables. Findings & Value added: In our simulations we experimented with the quality of sales service provided by company’s sales representatives. We investigated the impact of quality of sales service on company KPIs under the changing environment circumstances represented by disturbance agent. The quality of sales service is a part of quality of service and thus it affects the perception of brand and loyalty of customers towards the company. In our simulation setup we work with two types of customers, long-term customers and new ones. The result is that quality of sales service has mostly positive effects on company KPIs.

Negotiations
Opis:
The key standards for negotiation in multi agent systems are considered. Multiagent systems represent one of the most promising technological paradigms for the development of autonomous, distributed, open and intelligent software systems. Particularly because the agents are autonomous and cannot be assumed to be benevolent negotiation is critical to resolve conflicts. Examples of conflicts include conflicts over the usage of joint resources or task assignments and conflicts between a buyer and a seller in electronic commerce. The process of negotiations may be of many different forms, such as auctions, protocols in the style of the contract net, and argumentation. The paper focuses on the analysis of specification standards provided by FIPA (Foundation of Intelligent Physical Agents). The first part of the study will present basic information about the negotiations in multi-agent systems. For this purpose, will be shown the importance of negotiations in modeling interactions software agents, types of messages used in multi-agent systems using standard FIPA ACL and options for online auctions, which can be aided by software agents. The second part will present the commonly used protocols consistent with FIPA specifications. To this end, we will discuss eleven diagrams depicting the model sequences of interaction agents. Their use can be found in the construction of multi-agent systems.

Opis:
The paper presents an application of an auction algorithm in a multi-agent computer system for managing the unbalanced energy in a microgrid. The main goal of the system is to control and minimize the deviations of the current energy dem and from the actual energy production, using an auction algorithm. Distributed generation is assumed in the microgrid, with renewable power sources. The energy storages and the controllable power sources improve the system operation. The differences between the actual demand and produced energy are caused by unpredictable level of electric power generation by uncontrolled sources, like wind turbines or solar panels, and/or randomness of power utilization. The system will tend to balance out these differences on-line in short time intervals (less than one minute) to follow-up varying levels of local power generation and loads.

Opis:
This paper addresses the problem of resource division for robotic agents in the framework of Multi-Agent System. Knowledge of the environment represented in the system is uncertain, incomplete and distributed among the individual agents that have both limited sensing and communication abilities. The pick-up-and-collection problem is considered in order to illustrate the idea presented. In this paper a framework for cooperative task assignment to individual agents is discussed. The process of negotiating access to common resources by intercommunicating agents is modeled and solved as a game against Nature. The working of the proposed system was verified by multiple simulations. Selected, exemplary simulations are presented in the paper to illustrate the approach discussed.

Opis:
Previous studies in multi-agent systems have observed that varying the type of information that agents communicate, such as goals and beliefs, has a significant impact on the performance of the system with respect to different, usually conflicting, performance metrics, such as speed of solution, communication efficiency, and travel distance/cost. Therefore, when designing a communication strategy for a multi-agent system, it is unlikely that one strategy can perform well with respect to all of performance metrics. Yet, it is not clear in advance, which strategy will be the best with respect to each metric. With multi-agent systems being a common paradigm for building distributed systems in different domains, performance goals can vary from one application to the other according to the domain’s specifications and requirements. To address this issue, this work proposes a genetic algorithm-based approach for learning a goal- oriented communication strategy. The approach enables learning an effective communication strategy with respect to flexible, user-defined measurable performance goals. The learned strategy will determine what, when, and to whom information should be communicated during the course of task execution in order to improve the performance of the system with respect to the stated goal. Our preliminary evaluation shows that the proposed approach has promising results and the learned strategies have significant usefulness in improving the performance of the system with respect to the goals.

Opis:
Negotiation is an interaction that happens in multi-agent systems when agents have conflicting objectives and must look for an acceptable agreement. A typical negotiating situation involves two agents that cannot reach their goals by themselves because they do not have some resources they need or they do not know how to use them to reach their goals. Therefore, they must start a negotiation dialogue, taking also into account that they might have incomplete or wrong beliefs about the other agent’s goals and resources. This article presents a negotiating agent model based on argumentation, which is used by the agents to reason on how to exchange resources and knowledge in order to achieve their goals. Agents that negotiate have incomplete beliefs about the others, so that the exchange of arguments gives them information that makes it possible to update their beliefs. In order to formalize their proposals in a negotiation setting, the agents must be able to generate, select and evaluate arguments associated with such offers, updating their mental state accordingly. In our approach, we will focus on an argumentation-based negotiation model between two cooperative agents. The arguments generation and interpretation process is based on belief change operations (expansions, contractions and revisions), and the selection process is a based on a strategy. This approach is presented through a high-level algorithm implemented in logic programming. We show various theoretical properties associated with this approach, which have been formalized and proved using Coq, a formal proof management system. We also illustrate, through a case study, the applicability of our approach in order to solve a slightly modified version of the well-known home improvement agents problem. Moreover, we present various simulations that allow assessing the impact of belief revision on the negotiation process.

Opis:
We present a system to generate poems based on the information extracted from input text such as blog posts. Our design uses the blackboard architecture, in which independent specialized modules cooperate during the generation process by sharing a common workspace known as the blackboard. Each module is responsible for a particular task while generating poetry. Our implementation incorporates modules that retrieve information from the input text, generate new ideas, or select the best partial solutions. These distinct modules (experts) are implemented as diverse computational units that make use of lexical resources, grammar models, sentiment-analyzing tools, and languageprocessing algorithms. A control module is responsible for scheduling actions on the blackboard. We argue that the blackboard architecture is a promising way of simulating creative processes because of its flexibility and compliance with the Global Workspace Theory of mind. The main contribution of this work is the design and prototype implementation of an extensible platform for a poetry-generating system that may be further extended by incorporating new experts as well as some existing poetrygenerating systems as parts of the blackboard architecture. We claim that this design provides a powerful tool for combining many of the existing efforts in the domain of automatic poetry generation.

In this paper we discuss the case of an intelligent city lighting system which acts towards fitting the actual enyironment needs related to lighting. It is accomplished by performing some actions when an enyironment state ehanges but also by predieting the state ehanges on the basis of data proyided by sensors. The problem complexity requires using formal model of a system enabling a problem decomposition and processing parallelization.
Rosnące koszty energii, a także troska o środowisko naturalne stymulują rozwój technologii zmniejszających zużycie energii. W artykule dyskutowany jest inteligentny system oświetlenia miejskiego, którego celem jest dostosowywanie pracy oświetlenia do aktualnych potrzeb. Osiąga się to przez podejmowanie odpowiednich akcji w warunkach zmiany stanu środowiska, ale także przez predykcję jego stanu, na podstawie otrzymywanych danych sensorycznych. Złożoność obliczeniowa tak postawionego zadania sterowania wymaga użycia formalnego modelu systemu, pozwalającego na dekompozycję problemu i zrównoleglenie obliczeń.

The publication presents the structure of the agent system, tasked with control of the formation of unmanned port tugboats capable of performing pilot and towing services. The use of autonomous tugboats with installed software was presented with respect to the existing regulations related to Resolution MSC.467 developed by the Maritime Safety Committee (MSC) belonging to the International Maritime Organization (IMO), which creates guidelines for the definition and harmonization of the structure and format of maritime services in the context of e-navigation. The use of a multi-agent system structure enables synergistic cooperation of tugboats carrying out joint port operations, such as: assistance in maneuvers of ships, precision movement of ships and other objects in port areas, monitoring and patrolling of port areas, carrying out ice operations, carrying out inspections of quays, the possibility of assistance in liquidation of petroleum and similar pollutant spills. The paper presents the structure of the agent system and the description of possible scenarios of port operations. The control algorithms and the applied methods of artificial intelligence, such as evolutionary algorithms with elements of fuzzy logic, were discussed. The recorded traffic parameters from the actions carried out in the simulator of the marine navigation environment were presented.

Inteligentne systemy rozproszone są coraz szerzej stosowane w różnorodnych dziedzinach nauki. Przykładem najprostszego systemu rozproszonego jest organizacja ludzka, która poprzez szereg cech takich jak kooperacja, negocjacja oraz koordynacja jest w stanie wspólnie rozwiązywać rozmaite problemy. System złożony z komunikujących się oraz współpracujących ze sobą agentów jest w stanie osiągnąć zadany im wcześniej cel. Sytuacje, które wymagają rozwiązania problemów o charakterze rozproszonym lub złożonym obliczeniowo, takie jak wyszukiwanie informacji w sieci, zarządzanie sieciami, symulacje rynku, wspomaganie zarządzania w przedsiębiorstwie czy kontrola ruchu lotniczego, ukazują szerokie pasmo możliwości stosowania systemów wieloagentowych. Systemy oparte na agentach mogą znaleźć swoje zastosowanie również w transporcie. Projektowanie systemów sterowania i zarządzania ruchem, modelowanie ruchu oraz planowanie systemów transportowych z użyciem systemów multiagentowych pokazuje możliwości dalszego rozwoju transportu jako inteligentnej dziedziny. W artykule przedstawiono sposób działania systemu wieloagentowego oraz możliwości jego wdrożenia w dziedzinę transportu. Opisano rodzaje agentów, które można zastosować w systemach wieloagentowych oraz przykłady symulacji z ich użyciem. Przedstawiono następujące przykłady: model symulacji ruchu we francuskim mieście La Rochelle; budowa modelu sieci aglomeracji poznańskiej z wykorzystaniem go do symulacji wieloagentowej w środowisku MATSim oraz symulacja systemu zarządzania ruchem na skrzyżowaniach w symulatorze opracowanym przez naukowców z Melbourne. Artykuł kończy krótkie podsumowanie opisujące korzyści płynące z zastosowania systemów multiagentowych i ich przyszłości w dziedzinie ITS.
Distributed intelligent systems are increasingly used in various fields of science. The example of simplest distributed system is human organization. With features such as negotiation, cooperation and coordination people are able to jointly solve variety of problems. The system consists of communicating and cooperating agents who are able to achieve goals that were set. Situations requiring solution of distributed or complicated character such as searching of an information in the Internet, network management, market simulation, management support in the company or supervision of air traffic present wide range of possibilities of multi-agent system use. Systems based on agents may also be used in the transport. The development of technology has allowed to use artificial intelligence in such fields of science as transport and traffic engineering. The next step in development of intelligent transportation systems is application of the multi- -agent systems. Agent based systems may find their use in traffic control systems, modeling and planning of transportation systems in cities. In the article types of agents that might be used and examples of simulation with the practical application are presented. Following examples are given: traffic simulation model in the French city of La Rochelle; construction of the Poznań agglomeration model with the simulation implemented in the MATSim as well as simulation of the traffic at intersections management system implemented by the scientists from Melbourne. The article concludes with short summary of advantages of multi-agent systems and their future application in the ITS.

Opis:
In recent years, an increasing trend in application of autonomous mobile robots in multi-agent systems worldwide has highlighted the importance of robot path planning. In this context, one of the main problems includes optimal route determination and collision avoidance development for multi-robot systems. In many situations, using multi-robot systems in the same environment is a good strategy in managing tasks, and an example of which can be the logistic environment. This paper presents robot control algorithms used for transport managing in virtual warehouses. The problem of multi-robot path planning in this paper refers to establishing an optimized path and avoiding obstacles. The algorithm proposed by the authors assumes control over the work of a single robot, in cooperation with other robots, in the same environment. The robot performs the task, which is the transport of resources from distribution points to points of storage, while the routing algorithm is used to evaluate the effectiveness of the algorithms. Simulation results show that the proposed method can effectively improve the performance of the planned path.
W ostatnich latach tendencja wzrostowa stosowania autonomicznych robotów mobilnych w systemach wieloagentowych spowodowała wzrost znaczenia planowania ścieżek robotów. W tym kontekście jednym z głównych problemów stało się wyznaczenie optymalnej trasy ruchu robota oraz unikania kolizji. W wielu sytuacjach zastosowanie systemów wieloagentowych jest dobrą strategią do zarządzania przepływem zadań w określonym środowisku, przykładem może tutaj posłużyć środowisko logistyczne. Niniejszy artykuł przedstawia algorytm sterowania ruchem robotów w zarządzaniu transportem w wirtualnych magazynach. Problem planowania ruchem robotów w ramach niniejszego artykułu odnosi się do znalezienia optymalnej ścieżki poruszania się między miejscem początkowym a docelowym w taki sposób, aby uniknąć przeszkód. Proponowane przez autorów algorytmy zakładają kontrolę pracy jednego robota, we współpracy z innymi robotami, w tym samym środowisku. Każdy robot wykonuje zadanie poprzez transport zasobu z punktów dystrybucji do punktów składowania. Proponowane algorytmy wyznaczania tras są ocenianie pod względem czasu realizacji zadań oraz wydajności energetycznej. Wyniki symulacji wskazują, że proponowana przez autorów metoda może skutecznie zwiększyć wydajność planowania ścieżek ruchu robotów.

Opis:
In this paper, an energy coordination control method based on intelligent multi-agent systems (MAS) is proposed for energy management and voltage control of a DC microgrid. The structure of the DC microgrid is designed to realize the mathematical modeling of photovoltaic cells, fuel cells and batteries. A two-layer intelligent MAS is designed for energy coordination control: grid-connection and islanding of a DC microgrid is combined with energy management of PV cells, fuel cells, loads and batteries. In the hidden layer and the output layer of the pro-posed neural network there are 17 and 8 neurons, respectively, and the “logsig” activation function is used for the neurons in the network. Eight kinds of feature quantities and 13 different actions are taken as the input and output parameters of the neural network from the micro-source and the load, and the as the control center agent’s decision-makers. The feasibility of the proposed intelligent multi-agent energy coordination control strategy is verified by MATLAB/Simulink simulation, and three types of examples are analyzed after increasing the load. The simulation results show that the proposed scheme exhibits better performance than the traditional approaches.
