Opis:: The multiagent approach to modelling, traditionally dedicated for distributed systems, can be applied on any platform where there are more processes or control threads. The world of surface transport is a typical example of such a situation where high numbers of dynamic entities (agents) interacting with each other represent a complex problem to solve, analyse and visualise. The main focus of this paper is on functional description of the traffic control problem at the rail-road intersection. Unlike conventional approaches, this model assumes usage of modern (infrastructure-to-vehicle, vehicle-to-vehicle) communication technologies as an essential base of cooperative intelligent transportation systems. The authors use the development toolkit NetLogo, explaining step-by-step the key programming details, to get a comprehensive overview of the operation of the entire system through simple definitions of a number of simple cooperating agents. The introduced model is implementation free and shows newly offered functionalities on the principal level, while a minimum theory of collective intelligence hidden in the background is needed.

Opis:: This paper is concerned with cluster consensus of linear multi-agent systems via a distributed event-triggered control scheme. Assume that agents can be split into several clusters and a leader is associated with each cluster. Sufficient conditions are derived to guarantee the realization of cluster consensus by a feasible event-triggered controller if the network topology of each cluster has a directed spanning tree and the couplings within each cluster are sufficiently strong. Further, positive inner-event time intervals are ensured for the proposed event-triggered strategy to avoid Zeno behaviors. Finally, a numerical example is given to illustrate the effectiveness of the theoretical results.

Opis:: Novel concept of monitoring systems integration, reference models and test application for manufacturing are presented in the paper. Research results are an answer for industry needs for development of IT solutions that will allow to integrate information flow in production systems. The idea of standalone advanced monitoring devices connection with Shop Floor Control, MRP/ERP and machine operators is discussed. The concept of monitoring systems integration has been formally described by reference models. They corresponds with original multilayer data structure proposed on the base of data tree. Data model allows to describe orders, products, processes and to save monitoring results. Both kind of models has been the base for implementation of the integrated monitoring system demonstrator. The demonstrator developed in the frame of research was built on the base of multiagent technology. It allows to keep high flexibility and openness of the system, as well as easy implementation of various intelligent algorithms for data processing. Currently, an application of integrated monitoring system for real production system is developed. The main problems and future development of monitoring integration in discrete production are presented and discussed in the article.

Opis:: Rozwój systemów produkcyjnych oraz stały wzrost oczekiwań klientów wymaga od firm coraz szerszego wprowadzania systemów nadzorujących procesy wytwórcze, stan maszyn oraz jakość produktów i historię ich wytwarzania. Monitorowanie procesów, maszyn i produktów, jest technicznie możliwe za pomocą coraz bardziej udoskonalanych systemów wykorzystujących zawansowane metody pomiarowe, algorytmy przetwarzania danych oraz wsparcie układów wykorzystujących tzw. sztuczną inteligencję. Jednakże wprowadzenie powszechnego nadzoru nad całymi procesami, kluczowymi maszynami i wszystkimi wyrobami wymaga szybkiego przetwarzania bardzo dużej liczby danych. Dodatkowo system taki musi być zintegrowany z funkcjami sterującymi. Implementacja zintegrowanego systemu monitorowania na bazie powszechnie stosowanej architektury klient-serwer wymagałaby budowy skomplikowanego, drogiego i mało elastycznego systemu. W artykule przedstawiono badania prowadzone nad opracowaniem zintegrowanego wieloagentowego systemu monitorowania wytwarzania realizowane na Politechnice Warszawskiej w Zakładzie Automatyzacji Obrabiarek i Obróbki Skrawaniem.
Continuously growing international competition in manufacturing sector force companies to reduce costs, at the same time rapidly increase complexity of products and quality requirements. Continuous development of manufacturing systems and increase of customer expectations requires implementation of advanced control and monitoring systems. To meet growing requirements production process should be controlled on all steps. Systems of direct control of manufacturing system, manufacturing cells, machines and performance of orders should be used. Such a system should allow for monitoring of all steps of production process according to requirements of Life Cycle Management (LCM). In article are pointed main aspects of a distributed multiagent shop floor control and monitoring system developed at Warsaw University of Technology.

Opis:: The complexity and dynamics in groupage traffic require flexible, efficient, and adaptive planning and control processes. The general problem of allocating orders to vehicles can be mapped into the Vehicle Routing Problem (VRP). However, in practical applications additional requirements complicate the dispatching processes and require a proactive and reactive system behavior. To enable automated dispatching processes, this article presents a multiagent system where the decision making is shifted to autonomous, interacting, intelligent agents. Beside the communication protocols and the agent architecture, the focus is on the individual decision making of the agents which meets the specific requirements in groupage traffic. To evaluate the approach we apply multiagent-based simulation and model several scenarios of real world infrastructures with orders provided by our industrial partner. Moreover, a case study is conducted which covers the autonomous groupage traffic in the current processes of our industrial parter. The results reveal that agent-based dispatching meets the sophisticated requirements of groupage traffic. Furthermore, the decision making supports the combination of pickup and delivery tours efficiently while satisfying logistic request priorities, time windows, and capacity constraints.

Opis:: In this paper some mechanisms of the multicriteria procurement auctions are discussed, including the elements of the decision support to the auction organizer, as well as to the bidders. The auction mechanisms are considered in the context of attaining incentive compatible decisions. Using domination relations formulated in the criteria space, different rules for the improvement of offers in successive rounds of the auction process are analyzed. The general discussion is illustrated by an example of an iterative multicriteria closed-bidding auction conducted with the use of a multi-agent computer-based system. The system supports submission of offers, multicriteria analysis performed by the auction organizer, simulation, and analysis of the competing bidders' behavior. Experimental results of sessions conducted with the use of the system are analyzed.

Opis:: An output-feedback decentralised formation control strategy is pursued under pole-region constraints, assuming that the agents have access to relative position measurements with respect to a set of neighbors in a graph describing the sensing topology. No communication between the agents is assumed; however, a shared one-way communication channel with a pilot is needed for steering tasks. Each agent has a separate copy of the same controller. A virtual structure approach is presented for the formation steering as a whole; actual formation control is established via cone-complementarity linearization algorithms for the appropriate matrix inequalities. In contrast to other research where only stable consensus is pursued, the proposed method allows us to specify settling-time, damping and bandwidth limitations via pole regions. In addition, a full methodology for the decoupled handling of steering and formation control is provided. Simulation results in the example section illustrate the approach.

Opis:: An event-triggered adaptive control algorithm is proposed for cooperative tracking control of high-order nonlinear multiagent systems (MASs) with prescribed performance and full-state constraints. The algorithm combines dynamic surface technology and the backstepping recursive design method, with radial basis function neural networks (RBFNNs) used to approximate the unknown nonlinearity. The barrier Lyapunov function and finite-time stability theory are employed to prove that all agent states are semi-globally uniform and ultimately bounded, with the tracking error converging to a bounded neighborhood of zero in a finite time. Numerical simulations are provided to demonstrate the effectiveness of the proposed control scheme.

Opis:: The automation of maritime transport is an indispensable trend towards full autonomy of maritime vessels. In this paper, an attempt was made to present the control system for port autonomous vessels using an agent system. On the basis of the conducted research, in order to optimize the energy consumption related to the movement of tugboats, the shape of the hull and the shape of the formation in which 4 tugboats are moving were selected. Several scenarios of navigational situations that may take place in port waters have been recognized. The conducted analysis have shown that the optimal shape of the hull of tugboats, the shape of the formation in which they move, as well as the determination of the passage route for the implementation of a specific task, can contribute to reducing both the carbon footprint and the energy consumption of the propulsion systems of tugboats. This is of significant importance in terms of reducing exhaust gas emissions in and around ports.

Opis:: During a global health crisis, a country’s borders are a weak point through which carriers from countries with high morbidity rates can enter, endangering the health of the local community and undermining the authorities’ efforts to prevent the spread of the pathogen. Therefore, most countries have adopted some level of border closure policies as one of the first steps in handling pandemics. However, this step involves a significant economic loss, especially for countries that rely on tourism as a source of income. We developed a pioneering model to help decision-makers determine the optimal border closure policies during a health crisis that minimize the magnitude of the outbreak and maximize the revenue of the tourism industry. This approach is based on a hybrid mathematical model that consists of an epidemiological sub-model with tourism and a pandemic-focused economic sub-model, which relies on elements from the field of artificial intelligence to provide policymakers with a data-driven model for a border closure strategy for tourism during a global pandemic.

Opis:: The paper describes a complete framework that uses a multi-agent approach for production scheduling in a foundry. Different types of autonomous agents have been designed, each playing a different role in the supply chain management of the fodundry, along with their responsibility and behavior in the system. In order to generate a proper and reliable schedule the agents negotiate with each other by sending messages compliant to FIPA ACL standard. A prototype of the system has been implemented in JADE and allowed to conduct preliminary simulation of the system. Although some agents some agents have been omitted in the prototype, it was possible to verify the main assumptions of the system, as well as, to indicate and discuss potential problems with its implementation into production practice.
