模糊数学在牧草产量预报中的应用

本文在“广义Fuzzy运算的综合评判”的基础上,并结合牧草产量预报实践,提出了一个经验“模型V”,简称“综合决策模型”。 该模型不仅具有计算简捷,容易为群众掌握的优点,而且还扩大了“广义模糊运算的综合评判”的应用范围,为了弥补其不足,还运用数学统计法建立如下的预报模型: (?)=-6.8223-0.4871R_1 0.3033R_2 0.0791R_3 2.8231R_4 0.6361R_5 (7)同时,还用周期方差分析来预报牧草产量。最后,综合运用了上述3种方法来预报牧草产量,提高了预报的精确度,效果更好。本文还举例说明了计算方法,并且讨论了同时运用几种方法进行产量预报的必要性和优越性。

APPLICATION OF FUZZY MATHEMATICS TO THE PREDICTION OF HERBAGE YIELD

An empirical "Model V", simply called"synthetic decision model"was developed on the basis of the "synthetic judgement model with generalized fuzzy operation" in the practice of predicting herbage yield. This model is written as :The model not only had obvious advantage of being calculated simply and being popularized easily but broadened the scope of application of the"synthetic judgement model with generalized fuzzy operation". In order to make up some deficiency, statistics was used for developing the fol...
