模糊SOFM网分类方法及其在农业中的应用

将模糊理论和自组织特征映射（ｓｅｌｆ－ｏｒｇａｎｉｚｉｎｇ ｆｅａｔｕｒｅ ｍ ａｐ， ＳＯＦＭ）网络相结合，构造出一种新的分类模型——模糊ＳＯＦＭ 模型．模糊ＳＯＦＭ 模型既利用了模糊理论解决不确定性问题的特性，又利用自组织映射特征网络具有较强的自学习、自适应能力、容错能力和模式识别能力的优点．能非常好地解决模糊或不确定系统中的多对象在多指标下的分类问题．实例结果表明用模糊ＳＯＦＭ 分类方法进行分类具有稳定、结果可靠等特点．

Enterprise resource planning implementation decision & optimization models

To study the uncertain optimization problems on implementation schedule, time-cost trade-off and quality in enterprise resource planning (ERP) implementation, combined with program evaluation and review technique (PERT), some optimization models are proposed, which include the implementation schedule model, the timecost trade-off model, the quality model, and the implementation time-cost-quality synthetic optimization model. A PERT-embedded genetic algorithm (GA) based on stochastic simulation technique is introduced to the optimization models solution. Finally, an example is presented to show that the models and algorithm are reasonable and effective, which can offer a reliable quantitative decision method for ERP implementation.
