摘要
本文根据主成分原理,对影响矿井原煤产量的生产因素进行综合分析,并构造出回归预测模型。同时,运用灰色系统理论使计划期未知数据白色化,进而预测出矿井原煤产量,为企业制定计划和组织生产提供了科学依据。
According to the theory of Chief Component, this paper makes comprehensive analysis with producting factors of the coal mine, and it also advances a set of mathematical models of coal output. Meanwhile, this paper uses the theory of Grey System to make plan target change into write, and it may evaluate coal output. This will provide the scientific basis for formulating plan and organizing production.
