Design And Implementation Of Tobacco Expert Decision Support System

Tobacco production process is a complex process. It is a challenging subject oftobacco production that how to simplify the tobacco production processes and toimprove the efficiency of tobacco production. In the tobacco production process, it isdifficult to promote the production technology, and lack the technical guidance oftobacco production; furthermore, it is not professional and conducive to collect the dataof production. So, the production work in tobacco companies is not efficient, and itbrought inconvenience on production and economic to those companies.This thesis analyses the main problems in the tobacco production, and finish thedesign and implementation of the tobacco expert decision support system. In thisprocess, we study many research in experts and decision-making system, we alsoreference the specific characteristics of Liangshan Prefecture, Sichuan Province. Theresult of test shows that it can improve the efficiency of tobacco production greatly.The consists of tobacco expert system includes: knowledge database, inferenceengine, the part of explain and the knowledge acquisition. The work of the expertsystem can be seen as the use of knowledge and reasoning. This system from bottom totop can be divided into the following layers:1. A support layer: this layer provides hardware support.2. Data layers: data layer contains a wide range of information, such as personnelinformation: user information, customer information, production personnel, scientificand technical personnel, farmers. Matter on a broader range, including: the impact oftobacco production and the intrinsic quality of soil, climate, topography and otherimportant factors of production, tobacco production farmers planting area, the intrinsicquality of the output of tobacco, tobacco infrastructure The construction details andother aspects of the content.3. Analysis layers: Analysis layer need to complete the model, the validation of themodel results and publishing features of the model, at the same time the data layer ofdata analysis, concluded.4.The application layer is the core of the system, the process of all businessfunctions. Previously analyzed layer model from business data access, analysis, finalresults show the process of processing. 5. Service layer is in one level of interaction in the business layer and the operatorof the entire system, it has two meanings, on the one hand, the performance of the finalresult in the analysis of the various subsystems of the application layer, the performancewhich can be based on the table form can also be combined with the GIS system ondisplay. On the other hand, the support and help of the technology center on technicalapplications as well as the expertise of the service object.6Access Layer: provides external access interface.After testing, the system can be completed normally tobacco policy-makingfunctions, and provide guidance for other tobacco expert decision support system.
