This paper describes an approach to distributed problem solving, that aims to model an architecture for a cooperative environment. Through the transformation of expert systems in a community of cooperating intelligent agents, it provides each agent with an envelope of tools and means to facilitate and direct their interactions and communications towards cooperation. The new approach, based on the conversational layered model of an agent, exploits reciprocal communication of activities, intentions and necessities between agents, creating a "conversation" focused to the distributed solution of a problem. This knowledge exchange is foreseen to be ruled by conversational laws and inferences, that have to be defined in the context of the Conversation and Cooperation layers. The model is mainly inspired by the sociological viewpoint, considering communication as a social process, the linguistic field of Speech Acts theory, introducing speech acts as planning operators, the concept of "tropistic agent" in Intelligent-agent Architecture, and the 'eco-systemic' viewpoint, capturing agents autonomy of the "eco problem solving" approach to distributed problem solving, where evolution in a dynamic system is due to the behaviour of simple agents.
