经济分析软件的设计与实现
 
摘  要:经济预测在现代经济生活中的作用变的越来越重要。它是企业确定政策,进行决策和制定计划的依据;是提高经营管理水平、改善计划工作的重要内容。该系统以某一燃气公司2001-2005年的历史数据信息为基础。它实现对公司的历史经营、客户发展状况进行统计和分析,然后根据分析结果采用合适的经济数学方法对历史数据作运算得出所需要的预测结果。本文首先对燃气公司的2001-2005年数据表中的历史数据作详细分析;其次,结合统计数学的知识,对现有的各种经济预测方法做深入的理解;第三,设计数据库。把表中的历史数据从Excel中导入到MySQL中,便于以后从数据库中调用数据和将数据库存入数据库中。第四,设计预测模型。以经济预测方法为基础,合理设计相关预测模型,实现对该燃气公司的2006年的经济预测工作。最后,对系统中仍存在的不足和缺陷做阐述,为以后的研究工作提出了一些自己的想法。
