In multi-agent systems, an agent which is dependent on the arrival of information from other agents may have to suspend processes if communication fails or if the information is simply not available. In most cases, communication is not guaranteed, and even if it were, there may be other factors affecting information transfer (such as the impossibility of or delays in acquiring the information at the source). Furthermore, if there is no knowledge about the state of the world, getting the appropriate response to an event becomes impossible. Moreover, in situations which demand a negotiated outcome, negotiation is impaired by missing information or uncertainty. Thus, reaching an outcome in such situations requires the development of decision frameworks that account for missing, contradictory or uncertain information.
