Information Fusion <strong>in</strong> Multi-agent System <strong>Based</strong> on Reliability Criterion 209<br />

S<strong>in</strong>ce agents can communicate with each other they can exchange <strong>in</strong>formation<br />

about objects that are detected by their sens<strong>in</strong>g devices and this way <strong>in</strong>crease their<br />

knowledge of the number and location of objects sensed by other team mates. The<br />

subject of the paper is the method of agents sens<strong>in</strong>g fusion which results <strong>in</strong> improvement<br />

of the process global knowledge.<br />

2.1 Workspace<br />

The workspace is a constra<strong>in</strong>ed, unstructured, flat area where a number of objects<br />

the robots are <strong>in</strong>tended to collect are scattered. The objects are def<strong>in</strong>ed by a set of<br />

<strong>in</strong>dices:<br />

, 1,2,…, (1)<br />

where is the total number of objects located <strong>in</strong>side the workspace. It has to be<br />

stressed that this number is not known to any agent. The location of each object is<br />

def<strong>in</strong>ed by a pair of coord<strong>in</strong>ates , , , . No data of these positions<br />

are provided to particular agents.<br />

2.2 Agents Description<br />

The system consists of robotic agents that are equipped with a sensory system<br />

that allows them to detect objects and determ<strong>in</strong>e the location of detected objects.<br />

Let us def<strong>in</strong>e the team of the robotic agents as a set:<br />
