The Research And Development Of Decision Support System For Forest Timber Assets Evaluation

Assets of the forest resources of forestry management is an important rule to achieving sustainable forest management. Timber forest assets occupies an important position in the assessment of forest resources, the establishment of timber forest assets evaluation decision support system is the direction of forest resources assets developments.For Hunan Province Longshan Forest Farm as an example, in the practical problems of timber forest assets, such as the poor operational model, access to information, low efficiency decision-making, management information systems, model technology, expert systems and decision support system Comprehensive used in timber trees assets and form a set of decision-making intelligent decision support system. Computer-operating system platform, set up mainly in small classes of data-processing module, assets evaluation decision support modules, articulated knowledge base and network connectivity modules. The data-processing module to achieve in small classes in small classes loaded with data collection, evaluation and forecast overall assessment of the results output, is an assessment of the main module. Property assessment decision support modules to achieve assessment of options, updated data derived forest and read the rules set reasoning, and so on. Knowledge Base articulated module to achieve decision support system and knowledge base of the connection work. Network connectivity realized prices for wood tables, economic indicators, such as online updating of the data. Through the system for timber forest assets to assess the accuracy and efficiency to provide a possible model of technology, assessment of the timber forest assets to reach or approach the level of experts.System development to comply with the idea of systems engineering and software engineering methods, the timber forest assets evaluation decision support system designed with user needs, feasibility, functional requirements.determine the system development strategy and operating system environment; on the basis of analysis the system, system architecture, database systems, the system connected with the World Wide Web address for the design and implementation; through the realization of human-computer interaction systems, database systems, knowledge base system, method of the system, the model and its management System, the system has strong data management, data updates, forecast trends, model application, planning the development, the system output.Application shows that the system will not only achieve the basic data on tree farms in small classes of high accuracy, high efficient management; timber forest assets to assess the decision-making and numerical simulation; timber forest assets will also assess the large number of systematic knowledge and improve the forestry director Departments of forest resources management decision-making effectiveness, scientific.
