On the basis of many years' statistical data of the Production of oil-tea camellia and other oil Plants in Hunan and in combination with gray-system iheon' and its method, correlative analyses are made of the Present Production of Hunan tea-oil Plantations. Their residual cycle GM (1,1) Prediction models and the long-term single-harvest Prediction models of four major oil Plants are established. Results show that, without great interference and disturbance, there are no radical changes in the current Productivity...

On the basis of many years' statistical data of the Production of oil-tea camellia and other oil Plants in Hunan and in combination with gray-system iheon' and its method, correlative analyses are made of the Present Production of Hunan tea-oil Plantations. Their residual cycle GM (1,1) Prediction models and the long-term single-harvest Prediction models of four major oil Plants are established. Results show that, without great interference and disturbance, there are no radical changes in the current Productivity of tea-oil Plantations in Hunan. By the year 2000, the total yield of tea-oil Plantations will not exceed 75 million kg.However, the single-harvest yields of the four oil Plants will increase to a certain degree.

以湖南省历年油茶及其它油料作物产量的统计数据为依据,综合运用灰色系统理论和方法,对湖南省油茶生产的现状进行了关联分析,并建立了具有残差周期的GM(1,1)预测模型组以及其它4种主要油料作物单产中长期预测模型。预测表明:在无较大干预措施的前提下,湖南省油茶生产的现状将不会有根本性改变,到2000年,其总产量将不会超过0.75亿kg;其它4种油料作物的单产,均有不同程度的提高。

This thesis,starting from working out the arrest points and the infl ection points of the function curves of the grey mathema tical model GM(1:1 )and its residual correction model and residual period model, derives the conditions for empliying these grey models to obtain a higher class of accuracy,thus enabling the user to decide which model should be used in the light of the state of given initial sequency data. And a rough estimation can also be made with respect to whether the fitting accuracy is satisfactory...

This thesis,starting from working out the arrest points and the infl ection points of the function curves of the grey mathema tical model GM(1:1 )and its residual correction model and residual period model, derives the conditions for empliying these grey models to obtain a higher class of accuracy,thus enabling the user to decide which model should be used in the light of the state of given initial sequency data. And a rough estimation can also be made with respect to whether the fitting accuracy is satisfactory or not before the cal culation results are completely known.

This article built the forcasting modes of main economy indexes for textile industry using Fuzzy system theory. The conclusion shows that the precision is very high in the total producing value and sailing income modes with a deviation periodical correcting method, but in the tax of interest mode, it is very low. This indicates that the production and profit do not grow at the same speed.
