The purpose of this chapter is to describe the broad range of application domains which implement many of the coordination strategies and techniques from the field of multi-agent systems. The domains include defense, transportation, health care, telecommunication and e-business. The objective of this chapter is to describe the diversity of the applications in which multi-agent coordination techniques have been applied to overcome the challenges or obstacles that have existed with regard to performance, interoperability and / or scalability. While the number of application domains is steadily increasing, the intent of this chapter is to provide a small sampling of domains which are applying coordination techniques to build intelligent systems. This chapter will also describe an emerging and important problem domain which can benefit from multi-agent coordination techniques.
