Economic Lot Scheduling Problem with Returns

Motivated by a case study of a company that produces car parts, we study the multi‐product economic lot scheduling problem for a hybrid production line with manufacturing of new products and remanufacturing of returned products. For this economic lot scheduling problem with returns (ELSPR), we consider policies with a common cycle time for all products, and with one manufacturing lot and one remanufacturing lot for each product during a cycle. For a given cycle time, the problem is formulated as a mixed integer linear programming (MIP) problem, which provides the basis for an exact solution. The application of this model for one of the core products of the case study company indicates a 16% reduction in cost compared to the current lot scheduling policy.     

Analytic connections between a double design and its original design in terms of different optimality criteria

In recent years, there has been increasing interest in the study of double designs. Various popular optimality criteria have been proposed from different principles for design construction and comparison, such as E(s²), generalized minimum aberration (GMA), minimum moment aberration (MMA), and minimum projection uniformity (MPU). In this article, these criteria are reviewed, and analytic connections between a double design and its original design in terms of these criteria are investigated. These connections are suitable for general original two-level factorial design, whether regular or non regular. In addition, these results provide strong insight into the relationship between double design and original design from different viewpoints.     

Partial sufficient dimension reduction on joint model of recurrent and terminal events

Joint modeling of recurrent and terminal events has attracted considerable interest and extensive investigations by many authors. The assumption of low-dimensional covariates has been usually applied in the existing studies, which is however inapplicable in many practical situations. In this paper, we consider a partial sufficient dimension reduction approach for a joint model with high-dimensional covariates. Some simulations as well as three real data applications are presented to confirm and assess the performance of the proposed model and approach.     

全球化背景下汉语“欧化”现象考证与分析

汉语"欧化"现象在中国起源较早,从20世纪初大量显现。当前汉语"欧化"的具体表现为汉语词汇的欧化、汉语词法的欧化以及汉语句法的欧化。而全球化背景下汉语"欧化"的影响因素主要为经济与文化全球化因素、大众媒体因素。因此,应对全球化背景下的汉语"欧化"现象,也应该从思想上正确认识和对待,政府要从宏观层面规范汉语的使用,相关的语言文字使用者应当起到示范作用,积极引导社会公众对汉字的规范性使用。     

语块理论及其在英语听力教学中的应用研究

国内外研究表明语块能够影响学生的词汇量、口语表达和写作水平,即同时影响输入信息和输出信息,而对于语块在听力方面的作用的研究相对欠缺,因此本文试图将语块法引入英语听力教学,探讨语块在英语听力中的作用。实验研究发现。语块听力教学法能够提高英语听力能力。     

世纪之梦：灵魂的拯救与重塑——鲁迅、韩少功对传统文化的矛盾判断

２０世纪，民族灵魂的拯救与重建，一直是中国文化人的民族之梦。鲁迅与韩少功，是“五四”时期和“新时期”中国非常突出的民族灵魂痼疾的探寻者。本文论述了鲁迅与韩少功对传统道德和文化心态的矛盾判断，旨在说明：我们生于既成的传统之中，谁也摆脱不了传统文化的制约。
