神经网络技术在客户信用评价中的应用 总被引:1,自引:1,他引:0
本文采用科学计算模型的方法实现了客户信用评价。该模型主要利用神经网络的反向传播(Back Propagation,简称BP)算法和收敛速度快、诊断正确的特点,建立了一个适合于企业客户信用评价的通用模型。同时对客户信用评价中的评价指标参数选择、数据收集与处理、构造BP网络模型以及BP网络计算进行了重点探讨。 相似文献

本文以德国某商业银行的真实客户信用数据为样本,将决策树方法应用于个人信用指标的筛选过程中,并与BP神经网络模型相结合构建成一个两阶段组合模型。研究表明,基于决策树—神经网络构建的个人信用评估组合模型对于测试样本的分类预测精度高于单一BP神经网络模型的分类预测精度。组合模型对于测试样本的总正确率平均值为75.45%,高出单一BP神经网络模型的总正确率近3个百分点。基于信息熵增益率分类原理的最优决策树挑选指标方法能合理去除非重要属性指标的干扰,使真正有效的属性指标输入神经网络主模型,提高模型分类预测的精准度。 相似文献

商业银行内部控制状况的模糊综合评价方法 总被引:3,自引:0,他引:3
随着国有商业银行的陆续上市,建立健全其内部控制体系成为紧迫任务,而内部控制体系的建立和健全离不开有效的评价方法,本文试用模糊综合评价方法对内部控制状况进行评价.模糊综合评价模型由因素集、评语集、权重集、分数集等构成,由专家或者熟悉内控的人员做出评价得出评语集;根据中国银监会的"内部控制评价计分方法表",用层次分析法(AHP)确定指标权重;用模糊聚类分析对评价结果进行归类和综合评价,并以某商业银行的内部控制为例说明这种方法的运用.我国目前内部控制评价缺乏定量评价,本文的模糊综合评价方法是对定量评价的一种尝试. 相似文献

We show that vendor financing appears in equilibrium as the result of repeated trade interactions between a buyer and a supplier when changing supplier is costly. Competition between suppliers forces them to offer a rebate before the relationship is initiated and switching costs allow the buyer to borrow from the supplier in the first period and to roll over the debt until the end of the relationship. The sequence of transfers is similar to a long-term financing structure. Our model suggests that switching costs allow small business owners to smooth their dividend income by using vendor financing. 相似文献

Extant studies of open book accounting focus primarily on data disclosure in long-term, committed purchasing arrangements. We extend research beyond that context by exploring the association between open book practices (in terms of nature and uses of disclosed data as well as conditions of data disclosure) and two different purchasing strategies. Three case studies are performed. Results indicate that within market procurement characterized by a transactional purchasing strategy, cost data primarily serve to reduce purchase price. Therefore, data disclosure is limited in scope and scale, occurs primarily during supplier evaluation and selection, and is characterized by an adversarial atmosphere. Incentives for suppliers to open their books focus on short-term tangible gains. Within a hybrid exchange arrangement characterized by a relational purchasing strategy, data disclosure supports cost reduction, e.g., through joint product development, and is more comprehensive. The atmosphere is less adversarial and suppliers reap long-term benefits. 相似文献

Hybrid performance evaluation of sustainable service and manufacturing supply chain management: An integrated approach of fuzzy dematel and fuzzy inference system

The aim of this paper is to propose a comprehensive framework for simultaneously measuring the performance of sustainable service and manufacturing supply chain management. Application of the proposed approach also results in reduced uncertainty of the performance measurement process caused by qualitative criteria evaluation. The proposed approach consists of two main steps. First, the fuzzy decision‐making trial and evaluation laboratory (DEMATEL) method has been used to determine important criteria by avoiding low influences; and then a Mamdani fuzzy inference system model has been adopted and applied for performance evaluation of sustainable supply chain management (SSCM). This model is employed in order to cope with the vagueness that exists in the SSCM performance investigation due to the vagueness intrinsic in the evaluation of criteria. In the proposed model, human reasoning has been modelled with fuzzy inference rules and has been set in the system, which is an advantage compared with those models in which fuzzy set theory and multicriteria decision‐making models are integrated. The proposed approach has been implemented in the pipe and fitting industry in order to highlight its application in real life. Sensitivity analysis has been carried out to determine the influence of service and manufacturing criteria on SSCM performance. The findings reveal that sustainable manufacturing criteria compared with sustainable service criteria have more effect on the performance of SSCM. 相似文献
