As result, there is a growing need for practical methodology for developing such systems. This paper presents a new Multi-Agent System Development (MASD) methodology, which has been developed over several years through analyzing and studying most of the existing agent-oriented ones. This methodology is constructed based on the strengths and weaknesses of existing methodologies. MASD ...

Three different versions of the MAST problem are distinguished and the approach for each one is outlined. The paper presents an investigation into the performance of the mobile client and computational results as well as performance evaluations are presented.

The presented approach focuses on reaching the optimal medical diagnosis with the minimum risk under the given uncertainty. Additional factors that play an important role are the required time for the decision process and the produced costs.

Complex real world scenarios require deep knowledge and expertise which can only be provided by specialists in the application area. However, it cannot be expected that such experts understand agent-based technology and simulation. Consequently, tools are required, which deliver a high level, easy usable interface. In this article we propose a new simulation framework based on the JADE framework. Besides extensions to deal with the time aspect, agent/environment interaction, visualization and load balancing, we also address the usability of the tool for specialists from different domains. For this, our framework, called Agent.GUI, provides an easy to use, customizable graphical user interface. Overall, Agent.GUI is a powerful tool for the development of multi-agent based simulations.

One reason is that sustainable energy production will rely on a large number of small and medium sized, decentralized energy production units. The aim is to replace a small number of large power plants. The energy supply strategy change puts completely different demands on the energy grid as well as on the business models to run those energy grids efficiently and, especially, securely. The future energy grid will have to deal with an autonomous, communication-driven, highly diversified and dynamic, and continuously changing environment. Additionally, while today's energy grids are run as independent systems the interaction between different energy networks, like natural gas or district heat, will strongly increase in the future. Inspired by ideas and techniques like Mini-CHP (combined heat and power) or Power-toGas , it is expected that future energy networks have to be seen as an entire hybrid energy network, where quantities of energy and energy forms will be dynamically exchanged and substituted as required. As a consequence, a lot of expertise that was gained in the past is no longer valid. On the other hand, little experience exists when it comes to shaping and managing the future energy grid. Due to the nature of multi-agent based simulation this class of simulation tools is well-suited for the simulation of future energy networks. The main advantages are the autonomy of agents, their highly developed interaction skills, the inherent distributed/decentralized approach of control in such a system and the high flexibility in the execution of tasks. This article presents Agent.GUI, which can be seen as a simulation toolkit and framework for complex and diversified energy systems. Based on the well-known JADE platform, the toolkit provides a wealth of specific features tailored to the needs for simulation of hybrid energy networks.

We first give an overview of the entire system, discussing our network architecture, applications, workflow solution, and middleware, and then describe how COSMOS was deployed and used at a motorway and a railway construction site. Key effects on the construction companies’ business operations are reported.

Because of this, m-commerce has to rely on new technologies, services and business models. Its potential emerges from the fact that the Internet has become an essential component in all aspects of our lives. On the other hand, mobile phones and PDAs have become an indispensable part of our daily routine as sources of all kinds of information and services and, especially, as a permanently available interface to our surroundings. Thus, not surprisingly, the number of mobile services is constantly increasing. Tomorrow, mobile devices will be intelligent assistants capable of anticipating many of our wishes and needs; but, for all these changes to happen, key issues of interoperability, usability, security and privacy still need to be addressed under the special scope of mobile services and commerce. The TAMoCo conference deals with such re...

Since remote construction sites are often not easily reached by terrestrial communication paths, a satellite link is established between the company headquarters and the site. A special network protocol deployed between the satellite gateways helps to overcome the known issues with TCP over long-delay links. Within the site, network coverage is provided by wireless LANs, including a Hiperlan-1 backbone with attached 2.4GHz-based cells, along with a DECT data network. The COSMOS client-server applications support the work of managers and engineers at the construction site by giving access to business and technical data, such as technical drawings centrally stored at the headquarters. For reasons of cost (satellite link) or due to a difficult radio environment a...
