面向对象的冬小麦产量预测专家系统（简称“ＯＯＷＦＥ”），采用面向对象的程序设计语言（Ｃ＋＋），所有因子的描述采用知识类型——原型类存储，将涉及产量因素的专家知识分类，规约成统计型、指标型和经验型三类知识原型，经过系统推理机制自动推理，形成冬小麦产量预测专家系统。该系统在与用户交互中实现专家系统的功能，系统预测准确率可达９０％ The object-oriented winter wheat yield forecasting expert system (OOWFE) adopts object-oriented programming language (C ++), and all the factors are described by the knowledge type-prototypical storage. The expert knowledge about yield factors is classified into Statistical prototype, index type and empirical type three types of knowledge prototypes are automatically reasoned through systematic reasoning mechanism to form winter wheat yield forecasting expert system. The system in the interaction with the user to achieve the function of expert systems, the system prediction accuracy of up to 90%
