Abstract: In view of that the existing emergency medical security system is not perfect, the medical emergency material dispatching ability of hospital departments is insufficient, the paper puts forward construction of large medical supplies for emergency dispatch system based on grey correlation degree. In the system design, according to the needs of practical application demand and expansion by material management control layer, emergency communication access layer, terminal equipment application layer of three layers of structure design, the paper has established a medical emergency material command scheduling system platform which sharing of rich access module and all kinds of emergency communication resource. Design and build of medical emergency material demand prediction model and scheduling model, can provide accurate medical emergency supplies scheduling program for the system, and through the simulation experiments, the rationalization of the generated medical emergency supplies scheduling scheme is validated, so enhance the ability of relevant government departments to treat emergencies.

Key words: emergency communications, emergencies, integrated dispatching
