Basic Loop

Cooperative Information Systems (CIS) become relevant to integrate different kinds of systems so as to work collaboratively for a common goal. CIS are considered by nature as dynamic systems, and one of the most difficult problems is how to model and control multiple simultaneous interactions among agents in a friendly way. Consequently, expressiveness becomes a problem related to the representation so far, the similar systems cope neither with the problem of expressiveness nor with multiple interactions in a satisfactory way. It is proposed an integrated methodology based on Coloured Petri Nets (CPN) in order to model the interaction mechanism in a CIS and reduce the associated complexity in the representation of the dynamic of the system. The methodology integrates mainly: (a) the action basic loop in order to represent the system interactions and to model organization conversations, (b) the CPN in the interaction design and system simulation, (c) the communicative acts of FIPA (Foundation for Intelligent Physical Agents), included in the Agent Communication Language Specification.

Formal Operations

This chapter focuses on a Petri Net-based model for team organization and monitoring. The applications considered are missions performed by several robots that cooperate in different ways according to the goals to be achieved. Formal operations on the Petri Net representing the mission plan allow the dynamic hierarchy of subteams to be revealed and the agents’ individual plans – including the relevant cooperation context – to be calculated. The model also allows several failure propagation ways within the team to be highlighted and local plan repair to be considered. Moreover Petri Nets allow direct implementation, and monitoring and control of the plan at each level of the organization: team, subteams, and individual robots.

Personal computers (PCs) are a powerful resource in the EM Laboratory, both as a means of automating the monitoring and control of microscopes, and as a tool for quantifying the interpretation of data. Not only is a PC more versatile than a piece of dedicated data logging equipment, but it is also substantially cheaper. In this tutorial the practical principles of using a PC for these types of activities will be discussed.The PC can form the basis of a system to measure, display, record and store the many parameters which characterize the operational conditions of the EM. In this mode it is operating as a data logger. The necessary first step is to find a suitable source from which to measure each of the items of interest. It is usually possible to do this without having to make permanent corrections or modifications to the EM.
