摘 要: 对信息熵理论进行了概述,提出了客观熵权(OEW)的概念,并给出了OEW的构造方法,进而建立了主成分投影(PCP)的综合决策模型,并在土地质量综合决策中进行了应用.结果表明,提出的方法是有效的、合理的. Information entropy theory is summarized in this paper. A new concept of objective entropy weight (OEW) is proposed and the construction method of OEW is given. According to OEW, a comprehensive decision-making model based on principal component projection (PCP) is set up, which is applied to land quality. The simulation results show that the proposed model is efficient and reasonable.
