Quality has been shown as the major criterion in many supplier selection studies. Among various quality assurance activities, process capability indices are widely used to quantify the relationship between the actual process performance and specification limits in many high-tech industries. By a suitable analysis of an index, a production department can trace and improve a poor process to enhance the quality level and satisfy customer requirements. Recently, some practical process capability control charts were developed for illustrating the continuous assessments of process capability. These charts contain information regarding the ability of the process to meet or exceed customer requirement over the life of a process. However, the process distribution is often ab-normal. Therefore, this study integrates the bootstrap procedure to construct a capability control chart for non-normal processes. The simulations show that the empirical coverage probability of our proposed chart is close to the desired coverage probability as the size of subgroup is large enough.
在许多供应商选择研究中,质量已被证明是主要的标准。在各种质量保证活动中,过程能力指标被广泛用于量化实际过程性能与规范限制之间的关系。通过适当的指标分析,生产部门可以跟踪和改进不良工艺,以提高质量水平,满足客户的要求。近年来,人们开发了一些实用的过程能力控制图,以说明过程能力的连续评价。这些图表包含有关过程在整个过程生命周期内满足或超过客户需求的能力的信息。然而,过程分布通常是反正态分布。因此,本研究结合自举法建构非正常过程的能力控制图。仿真结果表明,当子群的大小足够大时,我们提出的图表的经验覆盖概率接近期望的覆盖概率。

This essay aims to discuss the changes of capital structure toward stock returns and return on assets, with a further introduction of interference factors of exchange rate risks. The correlational changes of both factors would be analyzed in terms of different fluctuation levels. The empirical results show significant discoveries: both the factors have positive correlations. Reasons can be deduced from the willingness of trading firms, the company operational requirements, and the psychology of return expectation. Thus, this study suggests the investors to include exchange rate fluctuation index, while the government shall timely open up to corporate transactions and the corporate should carry out overall exchange rate and interest rate hedging.
本文旨在探讨资本结构对股票收益和资产收益的变化,并进一步引入汇率风险的干扰因素。根据不同的波动水平来分析这两个因素的相关变化。实证结果有显著的发现:两者之间存在正相关关系。究其原因,可以从交易企业的意愿、公司的经营需求和收益预期心理三个方面来推断。因此,本研究建议投资者纳入汇率波动指标,而政府应及时开放企业交易,企业应进行全面的汇率和利率对冲。

Yuan-Sheng Lee, H. Shih
For managing the behavioral effect of the risk preference of decision makers (DMs) in a group decision, this study adapts the TODIM (an acronym in Portuguese of Interactive and Multi-criteria Decision Making) to deal with risk decision and combines with incremental analysis (IA) and group ranks to construct an integrated multi-criteria group decision support model. In consideration of the ordinal rank of each DM using IA and the relative weights of DMs, the approaches for converting the ordinal data to cardinal data and determining the weights of DMs based on the eigenvector of their ranking distance comparison matrix are also compared and discussed. Furthermore, sensitivity analyses of the parameters of the value function and different weights of DMs demonstrate the robustness of the integrated model. An example proves the proposed model to be feasible.
为了管理群体决策中决策者风险偏好的行为效应,本研究采用TODIM (Interactive and Multi-criteria decision Making)来处理风险决策,并结合增量分析(IA)和群体排名,构建了一个集成的多准则群体决策支持模型。考虑到使用IA的每个DM的序数秩和DM的相对权重,比较和讨论了将序数数据转换为基数数据以及基于排序距离比较矩阵的特征向量确定DM权重的方法。此外,通过对价值函数参数和不同权重dm参数的敏感性分析,验证了模型的鲁棒性。算例验证了该模型的可行性。

As economies develop and the pace of life accelerates, there is an increasing demand for frozen agricultural products as well as for good quality and fresh products to enter the production chain. However, relatively little information is available regarding the management of this form of "cold chain" to ensure the quality of frozen food, especially within a developing country context. Therefore, this study aims to fill this gap in the literature and provide feasible guidance for frozen food manufacturers in developing countries to establish both internal and external quality management systems for their supply chains. Examining a frozen corn cobs manufacturer in China, it is found that internal quality management with preventative and traceability systems are closely related to product quality, while the effectiveness of supply chain quality management moderates the extent of such relationships. Furthermore, it is found that organizations in their early stages of development can enhance the quality level by effective management without investing additional capital.
随着经济的发展和生活节奏的加快,人们对冷冻农产品的需求越来越大,对优质新鲜产品进入生产链的需求也越来越大。然而,关于管理这种形式的“冷链”以确保冷冻食品质量的资料相对较少,特别是在发展中国家的情况下。因此,本研究旨在填补这一文献空白,为发展中国家冷冻食品生产企业建立供应链内部和外部质量管理体系提供可行的指导。通过对中国一家冷冻玉米芯生产商的考察,我们发现,具有预防和可追溯系统的内部质量管理与产品质量密切相关,而供应链质量管理的有效性调节了这种关系的程度。此外,研究发现,处于发展初期的组织可以通过有效的管理来提高质量水平,而无需投入额外的资金。

This study is to explore the relationship between the domestic banking industries devoting to the Corporate Social Responsibility (CSR) actions with their operating performance. In contrast to the previous studies, this study further observes the effect related to the bank risk taking degree. Regarding recent studies, it can be found the level of corporate social responsibility usually being access by qualitative indicators, but cannot observe the differences brought by the degree of the corporate devotion to CSR. In view of this, by using the CSR quantitative data provided by CSRHUB to the banking industry of Taiwan, taking into account of the operating performance and various levels of risk categories regression models, the empirical results confirm that when the banks devote to CSR, it will be helpful for the company accounting-based performance levels, but it could not explain the potential risk of default, only has a significant relationship with the operating risk. If the bank is the subsidiary of the financial corporation, although devoting to the CSR would increase the operating cost of the company; however, the external benefits associated with CSR could ease the pressure of having less operating profit, and mitigate the fluctuations in earnings.
本研究旨在探讨国内银行业企业社会责任行为与其经营绩效之间的关系。与以往的研究相比,本研究进一步观察了与银行风险承担程度相关的效应。从最近的研究中可以发现,企业社会责任的水平通常是通过定性指标来衡量的,而无法观察到企业社会责任投入程度带来的差异。有鉴于此,利用CSRHUB提供给台湾银行业的CSR量化数据,结合营运绩效与各层级风险类别回归模型,实证结果证实,当银行投入CSR时,会对公司会计基础绩效层级有所帮助,但无法解释潜在的违约风险,仅与营运风险有显著关系。如果银行是金融公司的子公司,虽然致力于企业社会责任会增加公司的经营成本;然而,企业社会责任带来的外部利益可以缓解经营利润减少的压力,减轻收益的波动。

As the rapid growth of e-commerce, how to convert participants into royal members or customers has become the major issue. The technology acceptance model (TAM) was the most popular theory to explain end-user's behavior towards information technology. How-ever, it stresses more the influence of information systems on consumer behavior and ignores the effect of social and psychological factors. Social identity theory provides a theoretical background to explain how psychological factors influence participant behavior. This re-search integrated both TAM and social identity theory to explore the factors affecting the positive behavioral intention of transaction virtual community (VC) members, so this study contributes to refine theory relating to behavioral intention in digital context. Research findings show that web service quality will enhance participants' social identification. Social identification will bring participants to positive behavioral intention, including spread pos-itive electronic word-of-mouth (eWOM), get information, and purchase intention. Finally, social identification is more powerful than web service quality. Traditionally, practitioners of transaction VC focus more on technological factors. These findings bring new insights for them.
随着电子商务的快速发展,如何将参与者转化为皇家会员或客户已成为主要问题。技术接受模型(TAM)是解释终端用户对信息技术行为最流行的理论。然而,它更多地强调了信息系统对消费者行为的影响,而忽略了社会和心理因素的作用。社会认同理论为解释心理因素如何影响参与者的行为提供了理论背景。本研究将TAM理论与社会认同理论相结合,探讨影响虚拟社区(VC)成员积极行为意愿的因素,有助于完善数字环境下行为意愿的相关理论。研究结果表明,网络服务质量会增强参与者的社会认同。社会认同会使被试产生积极的行为意向,包括传播积极的电子口碑、获取信息和购买意向。最后,社会认同比web服务质量更强大。传统上,交易型风投从业者更关注技术因素。这些发现为他们带来了新的见解。

Inventory Management and Pricing Decisions for a Supply Chain with Demand Leakage and a Return-Policy Contract 考虑需求泄漏和退货政策契约的供应链库存管理与定价决策

Fuzzy time series relies heavily on the length of intervals and the formulation of fuzzy relationships. This study proposes a combination of fuzzy c-means (FCM) and frequency-weighted fuzzy logical relationship groups (FLRG) to overcome these problems. It is noted that FCM simplifies the process of fuzzification as it avoids the subjective measures to determine the interval length. However, the results of FCM is sensitive to initial values and it is easily trapped in the local minima. To overcome this, we propose a method to identify the initial centers. The frequency-weighted FLRG is deemed reasonable as the frequency indicates the likelihood of the occurrence of the fuzzy logical relationships (FLR) in the future. To examine the effect of these two factors on the modeling accuracy, the performance of the proposed model is compared to the existing models of equal interval length with no weights, frequency-and-recentness-weights, and a modified model that takes equal interval length with frequency-weights. The results are verified by performing the procedures with various number of groups on the enrollment data as well as some stock indexes. The results show that the proposed method outperforms the other models on these data.
模糊时间序列在很大程度上依赖于区间的长度和模糊关系的表述。本研究提出模糊c均值(FCM)与频率加权模糊逻辑关系组(FLRG)相结合的方法来克服这些问题。注意到FCM简化了模糊化过程,因为它避免了确定区间长度的主观度量。然而,FCM的结果对初始值很敏感,容易陷入局部极小值。为了克服这个问题,我们提出了一种识别初始中心的方法。频率加权的模糊逻辑关系是合理的,因为频率反映了模糊逻辑关系在未来发生的可能性。为了检验这两个因素对建模精度的影响,将该模型的性能与现有的无权重等间隔长度模型、频率和最近度权重模型以及具有频率权重的等间隔长度模型进行了比较。通过对招生数据和一些股票指数进行不同组数的处理,验证了结果。结果表明,该方法在这些数据上优于其他模型。

Quality function deployment (QFD) is a successful product design tool for analyzing customer demands. Recently, researchers have combined QFD and grey system theory for solving small size, uncertain and incomplete data problems. However, some problems, such as single grey values, competitive analysis and prototype product selections, require further investigation. To resolve these issues, this study integrates interval grey numbers, QFD and TOPSIS techniques to develop a grey product design and selection (GPDS) method. GPDS can help product developers identify important engineering characteristics, perform a competitive analysis and select the best prototype product(s) under a small size and uncertain data environment. A real-world case study (paper facial mask) is offered to explain the research process of the GPDS method. The case results indicate that GPDS helps the case company identify important engineering characteristics, understand the intended market position of a product and select the best prototype product.
质量功能展开(QFD)是一种成功的分析顾客需求的产品设计工具。近年来,研究人员将QFD与灰色系统理论相结合,用于解决小尺寸、不确定和不完整数据问题。但是,在灰色值单一、竞争分析和原型产品选择等问题上还有待进一步研究。为了解决这些问题,本研究将区间灰数、QFD和TOPSIS技术相结合,建立灰色产品设计与选择(GPDS)方法。GPDS可以帮助产品开发人员识别重要的工程特性,进行竞争分析,并在小尺寸和不确定的数据环境下选择最佳原型产品。并以实际案例(纸质面膜)为例,说明了GPDS方法的研究过程。案例结果表明,GPDS可以帮助案例公司识别重要的工程特征,了解产品的预期市场地位,并选择最佳的原型产品。
