In this paper we present a conceptualization and a formalization to de ne agents' behaviors (as exhibited in agent to agent interactions), via an extension of Petri Nets, and show how behaviors of di erent agents can be aligned. We explain why these agents can be considered anticipatory, and the link between Business Information Systems and anticipatory(More)
PURPOSE We propose a simple methodology for heterogeneous data collection and central repository-style database design in healthcare. Our method can be used with or without other software development frameworks, and we argue that its application can save a relevant amount of implementation effort. Also, we believe that the method can be used in other fields(More)
Software agent-based negotiation is a major method to automate the interactions in electronic marketplaces and Internet enabled communities. The traditional approach is to let the agents to interact directly. In this paper it has been investigated how a mediator agent can improve the chances to reach the agreement via bargaining.

The manufacturing process in a Virtual Enterprise (VE) is a more complex task than in the single integrated enterprise case. We are proposing an architectural systematisation of the manufacturing and control structures in a VE, in the context of business processes and highlevel planning. For the Information Technology (IT) integration of the VE, we propose(More)
A population of committees of agents that learn by using neural networks is implemented to simulate the stock market. Each committee of agents, which is regarded as a player in a game, is optimised by continually adapting the architecture of the agents using genetic algorithms. The committees of agents buy and sell stocks by following this procedure: (1)(More)
Business processes consist of sets of individual and collaborative activities performed by agents (human of artificial) and the interactions between them. The agents have their own local beliefs and expectations about the behaviour(s) of the other agents. We represent these beliefs by using the ‘interaction belief’ concept. We show how a designer can reason(More)
