Based On The Mas Distributed Agricultural Expert System Development Platform

In recent years, because the steps of ES techniques have not caught up those of the development of Internet and correlative techniques, the development of ES has more limitations on some capacities. So, ES developing techniques ought to progressrapidly with the usages of the Internet -- a distributed and parallel computationenvironment and some correlative supported technologies.Agent technology, and mostly the research and application of MAS, is one of the boiling points of DAI. It is doing research on applied entity from the point of view of society. And as an independent entity, Agent takes significant effects on the development and implementation of complicated systems.The introduction of the mechanism of ES Platform, technology of MAS, and applied characters of Internet is carried out. After thinking these facts, this paper offers a theoretic opinion about to apply the technology of MAS and distributed computation to the design and implementation of ES Platform, and a practical architecture, which is mainly facing to agriculture field.On the research of knowledge representation and reasoning methodology, based on the characteristics of the agriculture knowledge, the traditional knowledge representation of Production Rules has been improved, and integrated with the Hierarchy conception and the method of Reliability, forming a Decision-making Group Representation. And apply Uncertain Reasoning arithmetic to do reasoning.Then, discuss the feasibility of the combination of Agent technology and ES development technology with an in-depth study on Agent theory and technology. And compare the Agent-Oriented software methodology and Object-Oriented methodology; demonstrate the feasibility of developing software components of some characters ofAgent with OO techniques and Web Service--a distributed computation technology,according to present software development architecture and standard system.On the design and implementation of the real software model, apply the new and advanced network framework and techniques, such as B/S 3-tier Model, .NET Framework and Data Binding, which providing standout capacity of network function for the real model.So, applying the MAS-based Distributed Agriculture ES Platform of the theoretic model and technical architecture studied and offered by this paper, is an exploration and attempt to the sustainable development of the ES development techniques, practical applications of Agent and the integration of advanced theories and techniques. Considering that limited experimental condition and modest academic level, many of this paper are needed to study further.
