integration of spatially distributed sensors, or the control of robots cooperated in
a factory. They might also be functionally distributed, such as the integration of
several professional medical diagnosis systems to solve complex cases. They
might even be scheduling distributed, for example in a factory, the production
line is composed of several working procedures, each scheduled by an expert
system.
(3) System integration — DAI systems well support modular design and
implementation. A complex system can be resolved into several comparatively
simple and task specific sub-modules, in order that the system can be easily
constructed, debugged and maintained. It is more flexible to handle errors of
decomposed sub-modules than a single integral module. On the other side, great
economic and social benefit will be gained if the many existing centralized AI
application systems can be used to construct distributed AI systems with minor
modifications. For example, it will be extremely time-saving and practically
effective if existing independent systems of liver diagnosis system, stomach
diagnosis system, intestines diagnose system, etc. can be slightly modified to
construct a complex expert system to diagnose digestive tract diseases. The
plug-in approach we proposed for agent construction is an effective means to
integrate existing AI systems.
(4) New approach to intelligent behavior — Implement intelligent behavior with
intelligent agents. To become societies of mind, AI systems should have
functions for interaction with the environment, as well as capabilities to
cooperate and coordinate with each other.
(5) Meanings in cognitive science — DAI can be used for research and
verification of the problems and theories in sociology, psychology, management,
etc. Cooperative MAS based on belief, knowledge, hope, intention, promise,
attention, object, cooperation, etc. provide effective means to understand and
simulate the cognitive problems.
Therefore, no matter technically or socially, the emergence and development
of DAI systems is imperative. It is also natural to apply DAI technologies to
solve large-scale martial problems. Presently, research in this domain has made
certain achievements in China.
