In order to cope with the competitive environment related to beauty industry sector in Indonesia, companies need to manage and evaluate customer interactions by enhancing Customer Relationship Management (CRM). This study aims to specify customer segment that has similar lifetime value with clustering method, hence company can conduct appropriate strategies to the right segment. Two-stage clustering method for segmenting customers is proposed in this study. Ward's method is used for choosing an initial number of cluster and K-Means method to perform clustering analysis. Two approaches using LRFM (Length, Recency, Frequency, Monetary) model and extended model called LRFM - Average Item (AI) variables in clustering process are compared by validity index to obtain the best result for customer segmentation. The result shows that adding new variable Average Item in LRFM model have no significant difference or better results in clustering. The ranking process based on Customer Lifetime Value (CLV) score is conducted using weighted LRFM model variables. Final weight score for all variables are obtained from Fuzzy AHP method. In summary, company also get several inferences such as customer characteristics of high and less potential customers. It can be a guideline for making the sale and marketing strategies.
为了应对与印尼美容行业部门相关的竞争环境,公司需要通过加强客户关系管理(CRM)来管理和评估客户互动。本研究旨在通过聚类方法指定具有相似终身价值的客户细分市场,从而公司可以对正确的细分市场进行适当的策略。本文提出了一种两阶段聚类的客户细分方法。采用Ward方法选择初始聚类数,采用K-Means方法进行聚类分析。通过有效性指标比较了在聚类过程中使用LRFM (Length, Recency, Frequency, Monetary)模型和扩展模型(LRFM - Average Item (AI)变量)的两种方法,得到了客户细分的最佳结果。结果表明,在LRFM模型中加入新变量Average Item对聚类结果没有显著性影响或有更好的聚类效果。基于客户终身价值(CLV)评分的排序过程使用加权LRFM模型变量进行。采用模糊层次分析法得到各变量的最终权重得分。综上所述,公司还得到了高潜在客户和低潜在客户的客户特征等几点推论。它可以作为制定销售和营销策略的指导方针。

Gamification refers to the inclusion of game design elements into non-game environment, which has been widely used in medical health, education and training, marketing activities and other aspects, and can promote users' willingness to continue to participate. At the same time, as an important marketing tool for enterprises, virtual community undertakes the functions of building communication and interaction platform, sharing and releasing information, and improving brand loyalty. With the intensification of virtual community competition among brands, how to improve the users' willingness to continue to participate is the key to the development of virtual community of brands. Firstly, based on the relevant research, this paper constructs a relationship model of gamification elements of virtual community on the intention of continuous use based on the theory of expectation confirmation and Expectation Confirmation Model of IS Continuance (ECM-ISC). Then we collected data through questionnaires, tested the reliability and validity, and used Smartpls to test the model and hypothesis. The results show that, two gamification elements (social and immersive elements) positively influence expectation confirmation and perceived usefulness, which in turn, positively affect user's satisfaction and continuance intention. At the end of this paper, the paper proposes some reasonable suggestions contributing to the development of virtual community and gamification, as well as indicating the direction of future research.
游戏化是指将游戏设计元素融入非游戏环境中,已广泛应用于医疗健康、教育培训、营销活动等方面,并能促进用户持续参与的意愿。同时,虚拟社区作为企业重要的营销工具,承担着搭建沟通互动平台、分享发布信息、提高品牌忠诚度等功能。随着品牌间虚拟社区竞争的加剧,如何提高用户的持续参与意愿是品牌虚拟社区发展的关键。首先,在相关研究的基础上,基于期望确认理论和IS连续性期望确认模型(ECM-ISC)构建了虚拟社区游戏化要素对持续使用意愿的关系模型。然后我们通过问卷收集数据,检验信度和效度,并使用Smartpls对模型和假设进行检验。结果表明,两个游戏化元素(社交元素和沉浸元素)正向影响期望确认和感知有用性,进而正向影响用户满意度和继续意愿。在本文的最后,本文提出了一些有助于虚拟社区和游戏化发展的合理建议,并指出了未来的研究方向。

Today, in the mass customization production environment, clothing companies face even more difficulties, such as the rapid and uncertain changes in customer requirements and their impacts on production time, cost, and quality of product. In order to survive and develop in such a competitive environment, apparel companies should clearly identify customers' demands in the development of new clothing products. Understanding customer demands and their purchasing process is the base knowledge required to ensure successful marketing activities. However, customers' demands and behavior are affected by many factors, some of which conflict with each other in the production process. Therefore, an understanding of consumers' critical evaluative criteria when purchasing clothing products is one of the most important issues in the new product development process. The purpose of this paper is to determine the clothing product attributes that are of greatest value to customers and predict consumer preferences for attributes by applying the conjoint analysis method. The final results showed that five criteria have the most influence on shopping customers' behavior, including design, fabric/fiber style, color, form, and price. These findings can support apparel managers in the new product development process.
在大规模定制生产的今天,服装企业面临着更多的困难,比如客户需求的快速和不确定的变化,以及这些变化对生产时间、成本和产品质量的影响。服装企业要想在这样一个竞争激烈的环境中生存和发展,就必须在服装新产品的开发中明确顾客的需求。了解顾客的需求和他们的购买过程是确保成功的营销活动所必需的基础知识。然而,顾客的需求和行为受到许多因素的影响,其中一些因素在生产过程中是相互冲突的。因此,了解消费者在购买服装产品时的关键评价标准是新产品开发过程中最重要的问题之一。本文的目的是通过联合分析法确定对顾客最有价值的服装产品属性,并预测消费者对属性的偏好。最终的结果显示,五个标准对购物顾客的行为影响最大,包括设计、面料/纤维风格、颜色、形状和价格。这些发现可以在新产品开发过程中为服装经理提供支持。

Non-performing loans has been one of the biggest problems in the banking sector. One alternative to minimize credit risk is to improve the evaluation of the applicant's credibility. Credit scoring is an evaluation of the feasibility of credit requests. For financial institution, poor credit may lead to an increase in non-preforming loans that may reduce bank productivity even in the event of financial crises and financial institutions bankruptcy Previously, credit scoring is based on the conventional statistics such as logistic regression and discriminant analysis. those techniques produce a good accuracy, some of the assumptions aren't accomplished by the data. Along the development of information technology, more advance approach named data mining has been developed. Therefore, this study used the Data Mining approach to solve NPL percentage problems in Indonesian bank, specifically in its mortgage loan. The classifiers used are decision tree C4.5 and random forest. Classifier with the best accuracy is random forest with Adaboost with 72.95%, on the other hand the worst accuracy performed by C4.5 with 68,7%. The best sensitivity performed by random forest complemented by Ada-boost with 0,730. It is considered as the best model in terms of prevent the type II error which could impact to the increase of non-performing loan in a bank. By the end of the research, it can be concluded that all types of random forest model out-perform the C4.5 decision tree.
不良贷款一直是银行业最大的问题之一。将信用风险降至最低的另一种选择是提高对申请人可信度的评估。信用评分是对信用请求的可行性进行评估。对于金融机构而言,信用不良可能导致不良贷款的增加,即使在金融危机和金融机构破产的情况下,不良贷款也可能降低银行的生产率。在此之前,信用评分是基于传统的统计数据,如逻辑回归和判别分析。这些技术产生了很高的准确性,有些假设并没有通过数据来实现。随着信息技术的发展,更先进的数据挖掘方法得到了发展。因此,本研究使用数据挖掘方法来解决印尼银行的不良贷款率问题,特别是其抵押贷款。使用的分类器是决策树C4.5和随机森林。准确率最好的分类器是Adaboost的random forest,准确率为72.95%;准确率最差的分类器是C4.5,准确率为68.7%。随机森林辅以Ada-boost的灵敏度为0,730,灵敏度最高。在防止第二类误差影响银行不良贷款增加方面,它被认为是最好的模型。研究结束时,可以得出结论,所有类型的随机森林模型都优于C4.5决策树。

Despite short video industry has been greatly developed in recent years and many people have been addicted to using short video apps, little is known about what motivates users to generate such loyalty. The purpose of this paper is to build a research model based on the satisfaction, perceived value, time-flexibility, ease of use and celebrity attractiveness to identify the antecedents of users' loyalty in the context of short videos. The model is tested against 278 actual users of Tik Tok. Structural equation modeling (SEM) is employed for data analysis. The findings put entertainment value, social value, perceived usefulness, and time-flexibility under the spotlight, but the ease of use and celebrity attractiveness don't support our hypotheses. We conclude that Tik Tok users' loyalty is strongly driven by satisfaction, which in turn is primarily driven by the perceived value and weaken by the time-flexibility. The implications are discussed in the paper.
尽管近年来短视频行业得到了很大的发展,许多人已经沉迷于使用短视频应用程序,但人们对用户产生这种忠诚度的动机知之甚少。本文的目的是建立一个基于满意度、感知价值、时间灵活性、易用性和名人吸引力的研究模型,以识别短视频背景下用户忠诚的前因变量。该模型针对278名抖音实际用户进行了测试。采用结构方程模型(SEM)对数据进行分析。研究结果将娱乐价值、社会价值、感知有用性和时间灵活性放在了聚光灯下,但易用性和名人吸引力并不支持我们的假设。我们的结论是,Tik Tok用户的忠诚度受到满意度的强烈驱动,而满意度又主要受到感知价值的驱动,并且受时间灵活性的影响减弱。本文对其意义进行了讨论。

In a dual-channel supply chain with hunger marketing, we study pricing and quality information disclosure decisions of the members when the information can be disclosed jointly, by the manufacturer or by the retailer. For each case, we also conduct sensitivity analysis to investigate the effects of the product compatibility with network sales and the information disclosure cost. The results show that hunger marketing strategy will improve the cost performance ratio and total demand of products, so as to improve the profit of manufacturers and supply chain. In addition, compared with the decentralized decision-making mode, the centralized decision-making mode helps supply chain to obtain more profit and disclose more quality information.
在具有饥饿营销的双渠道供应链中,研究了当信息可以由制造商或零售商共同披露时,各成员的价格和质量信息披露决策。针对每种情况,我们还进行了敏感性分析,考察产品与网络销售的兼容性和信息披露成本的影响。研究结果表明,饥饿营销策略会提高产品的性价比和总需求,从而提高制造商和供应链的利润。此外,与分散决策模式相比,集中式决策模式有助于供应链获得更多的利润,并披露更多的质量信息。

Measurement of Management behavior is a topic discussed in the field of Management. This paper presents the tendency of Managerial behavior in traditional Japanese banking sector and we focus on to the decision making on Fund management since it is the most important decision making in this industry. We also present how their behavior is anchored to their routine and negative behavior when they faced loss. The observation period measures for 20 years from 1997 to 2017 and we will show the 20 years trend of decision making using accessible data and a model created by using System Dynamics. We found the Managerial behavior on Fund management is conservative and avoiding risk instead of profit improvement for this observation period. Regarding to the interest rate for lending, it is not so linked to the policy rate though it is thought to be linked in general.
管理行为的度量是管理学领域讨论的一个话题。本文介绍了日本传统银行业的管理行为倾向,重点研究了基金管理决策,因为基金管理是银行业最重要的决策。我们还展示了当他们面对损失时,他们的行为是如何锚定在他们的日常和消极行为上的。观察期为1997年至2017年的20年,我们将使用可访问的数据和使用系统动力学创建的模型来显示20年的决策趋势。我们发现,在这一观察期,基金管理的管理行为是保守的,避免风险,而不是提高利润。至于贷款利率,虽然通常被认为与政策利率有联系,但它与政策利率的联系并不那么紧密。

This paper is aimed to explore the relationship between overseas background directors and the quality of information disclosure. Based on the background data of directors of Chinese listed companies from 2008 to 2017, our results show that: (1) overseas background directors can significantly improve the quality of information disclosure of listed companies; (2) compared with state-owned enterprises, overseas directors of private enterprises have a more significant impact on the quality of information disclosure. This study enriches the research on the influencing factors of information disclosure quality and the economic consequences of overseas background characteristics of senior executives, and has reference value for the selection and recruitment of management talents of listed companies, the improvement of enterprise information transparency and the maintenance of financial market stability.
本文旨在探讨海外背景董事与信息披露质量之间的关系。基于2008 - 2017年中国上市公司董事的背景数据,我们的研究结果表明:(1)海外背景董事能够显著提高上市公司信息披露质量;(2)与国有企业相比,民营企业海外董事对信息披露质量的影响更为显著。本研究丰富了对信息披露质量影响因素和高管海外背景特征经济后果的研究,对上市公司选拔和招聘管理人才、提高企业信息透明度、维护金融市场稳定具有参考价值。
