在企业生产和日常生活中,人们总是希望用最少的人力、物力、财力和时间
去办更多的事,这就是所谓的最优化问题。线性规划方法是解决最优化问题的有
效方法之一,因此受到人们的普遍关注。在企业生产过程中,生产计划安排直接
影响到企业的经济效益,而生产计划本质就是在目标一定时,对于人力、时间和
物质资源的优化配置问题。
1。综述了最优化方法,归纳了最优化闯题中线性规划和非线性规划模型的
解法,并给出了相应的matlab求解代码。
2。提出了基于信息增益率的用电客户指标选择方法,根据信息增益率的大
小选择对分类有贡献的指标。
In enterprise production and daily life, people always hope with the
least amount of human, material and financial resources and time to do
more things, this is the so-called optimization problem. Linear
programming method is to solve the optimal problem, so one of the effective
method by people's attention. In enterprise production process,
production plan directly affect the enterprise economic benefit, but in
essence is the production plan for the target certain human, time and
material resources optimization allocation problem.
1·Studying the optimization,summing up the solutions ofoptimization
problem for both linear and non-linear programming model and proposing
the matlabcode.
2·Proposing a new way based on information-gain-ratio to choose the
powercustomer indices,selecting the indices which are more contributive
to theclassification,in order to avoid over learning。
