The Research On Intelligence Distribution Information System Based Agent And Grid Technology

With the rapid development of national industry information,the organization in tourism industry have established own information management system in abundance for own benefit. But because lacks the unification on the plan,lots of redundant projects were established and reduced the efficiency,has affected the entire benefit on tourism industry. Information grid technology provides the brand-new platform for this question. the union of Agent and information grid technology,enhanced the system efficiency and the intelligence greatly. To apply the technology to tourism industry has vital significance.The research work in this dissertation was supported by the Beijing Nature Science Fund(No. 4042012)and the National Tourism Destination Marketing System Project. With the Data Mining and Agent Technology as the research basis and the Tourism Information Program of the Chinese National Tourism Administration(CNTA)as the application object. We studied the information grid system model based on Agent,apply the model to information management system in tourism industry and carried on the realization.The main work the thesis are as follows:(1)Established a information grid system model based on Agent. According to the goal which model needs to realize, the thesis defined the model level structure and the information expression method, and in detail function each model needs to realize, as well as each between interdependence. Proposed information grid computation model based on mobile Agent–iGrid, its main characteristic is to confine mobile Agent and information technology , realize complex information grid service by Agent's intelligence.(2)Realized information grid system model based on the Agent .Defined the express method of system information and the information service the system needed to provide, stipulate the decomposition principle about complex duty, designed connection of information to request Agent and information service Agent and carried on the realization. (3)Applied my findings to tourism industry and realized tourism information grid system, carried on the design including system organization, service, information service Agent, system service realization, information search Agent. Effectively improved a tradition search engine shortcoming on information match difference and inconvenient to use, provide the feasible reference plan for information grid gateway establishment.The system integrates the information grid technology and agent technology,it has many advantages. Owing to this system was developed with Java it has advantage of extensibility and portability. The research achievement and its successful application in the Tourism Information Program facilitated the successful combination of the information technology and tourism industry and made contribution to the tourism industry in its fulfillment of the information jump.
