The ideas of Distributed Artificial Intelligence are rapidly emerging in a series of application areas. In the frame of applied research on environmental protection and in particular management of chemical emergencies, an existing expert system has been transformed to a distributed knowledge based system. The development and testing environment used, called CooperA (Cooperating Agents), was purpose-built. During this experiment a number of theoretical ideas have been applied in a practical framework, resulting in a working prototype of the chemical emergencies management system. The CooperA system has been designed and developed as a software environment supporting the cooperation of heterogeneous distributed semi-autonomous knowledge based systems, presented to the user via a customised user interface. The prototype of the Chemical Emergency Management System produced, called Distributed ChEM (DChEM) contains a number of heterogeneous Expert Agents covering distinct areas of expertise which cooperatively establish the threat level of a particular chemical emergency. In this paper a description of the testbed and the application is followed by an evaluation of the transition process from a single expert system module to the CooperA/DChEM, and a description of how the various trends in D.A.I. have influenced this transition.
