摘要

在中国经济不断市场化发展的当下时代中,人们的生活水平和要求变得更加多样和丰富,有时候千里之外的食材也并非不切实际了。在此情况的要求下,为了保持食材的新鲜运输,冷链物流的发展就尤为重要。影响其发展的相关因素的研究和对江西省的农产品冷链物流的需求的预测,在一定程度上帮助了企业政府在未来的一段时期内提供决策依据,重点发展控制关联度较大的影响因素指标。

首先,本文通过搜集、整理有关冷链物流以及灰色理论的国内外文献资料,了解到当前农产品冷链物流和预测方法、指标的研究现状,使得对农产品冷链物流需求预测的问题有了整体认识。

其次,本文基于灰色理论,运用灰色关联度分析法构建了影响因素相关度模型和灰色 GM(1,1)需求预测模型,其中灰色 GM(1,1)预测模型还包括了有效性和灵敏度检验的研究。

再次,通过查阅江西省相关的报告年鉴,收集相关的数据,并对数据进行预处理筛选,基于相应原则和数据可得性,据剔除不明显指标数据,后带入模型进行运算求解,再对结果进行有效性和灵敏性分析研究和相关性比较。

最后,根据影响因素的相关性和预测结果提出相应的分析和建议。总结全文的不足和改进想法。

Abstract

In the current era of continuous market-oriented development of China's economy, people's living standards and requirements become more diverse and rich, and sometimes the ingredients thousands of miles away are not unrealistic. In this case, in order to maintain fresh transportation of food materials, the development of cold chain logistics is particularly important. To some extent, the research on the relevant factors affecting its development and the prediction of the demand for cold chain logistics of agricultural products in Jiangxi Province will help the enterprise government to provide the decision-making basis in the future period, and focus on the development and control of the influential factors with a large degree of relevance.

First of all, through collecting and sorting out the domestic and foreign literature about cold chain logistics and grey theory, this paper understands the current research status of cold chain logistics and forecasting methods and indicators of agricultural products, which makes a comprehensive understanding of the demand forecasting of cold chain logistics of agricultural products.

Secondly, based on the grey theory, this paper uses the grey correlation degree analysis method to build the correlation degree model of influencing factors and the grey GM (1,1) demand prediction model, in which the grey GM (1,1) prediction model also includes the research of validity and sensitivity test.

Thirdly, by consulting the relevant report yearbook of Jiangxi Province, collecting the relevant data, and pre-processing and screening the data, based on the corresponding principles and data availability, according to the elimination of the non obvious index data, then into the model for calculation, and then the effectiveness and sensitivity of the results are analyzed and compared.

Finally, according to the correlation of influencing factors and prediction results, the corresponding analysis and suggestions are put forward. Summarize the shortcomings and improvement ideas of the whole paper.
