高职物流管理专业订单培养模式实践研究

自从教育部教高[2006]16号文件颁布以来,高职的订单培养问题一直是高职教育的一个热点,但针对物流管理这类经管专业在具体的实践过程中出现了不少的问题,如何解决这些问题一直是经管类专业的重要课题。通过多年的实践,我们在对物流管理专业的订单培养过程中灵活根据用人单位的需要不断地进行人才订单培养模式的研究与实践,目前已经形成了全过程订单培养、半过程订单培养、推荐式订单培养三种主要的订单培养模式。文中对这些实践经验进行了研究与总结。     

基于外包的流程型生产订单选择问题研究

文章研究了流程型制造企业在生产能力有限、订单过剩情况下的订单选择问题。由于对订单的拒绝会影响自身的声誉,企业可以考虑将订单进行外包。首先将外包、声誉损失、订单选择等结合起来,构建了一个二次0-1整数规划模型,在企业利润最大化下对订单进行选择性的接受。然后,利用LINGO对模型进行检验,结果表明,该模型优于经典的订单选择模型。最后在不同订单排序方法下对模型再次进行验证,分析得出订单最大化利润排序是适用于本模型的最优排序方法。     

基于穿越策略的订单分批问题研究

本文针对配送中心的订单分批问题,在使用穿越路径策略的基础上,以最小化拣货路径为目标,建立了目标函数的数学模型,提出了改进的种子订单算法。将和原始订单相比,节约量最大的订单选为初始订单,并以此为条件为订单合并条件,逐一将订单组合,形成优化序列。本文将此算法运用到实际算例,并与传统的先到先服务和订单不分批的情况进行比较研究。

基于UML的钢铁企业APS订单计划系统建模

在基于APS的钢铁企业生产计划体系中,订单计划将客户订单转化为生产订单,其内容包括对订单在工序上的分解及交货期的初步确定等。本文从某钢铁企业对订单计划管理的实际需求出发,采用UML建模语言对钢铁企业APS中的订单计划系统进行需求分析,构造了系统的用例图和分析类图,并对订单拆分、库存匹配和产能匹配等典型用例进行了动态建模。本文研究的订单计划系统以客户订单为输入,可以实现订单的拆分、库存匹配和产能匹配,确定订单的交货期,进而合理安排中长期订单计划,达到帮助企业编制高效的生产批量计划和生产调度方案的目的。     

“货到人”订单分批拣选作业优化研究

由于传统的“人到货”订单拣选方式存在效率低、成本高等问题,无法满足仓储物流高效快捷的订单拣选作业模式。因此,“货到人”订单拣选系统得到了迅速发展。订单分批作为优化订单拣选作业的方法之一,如何实现合理有效的订单分批,提高订单拣选系统整体运作效率是研究的重点。以最小化货架搬运总次数为目标建立订单分批数学模型,采用订单相似度和萤火虫算法的联合优化方法实现订单分批。通过在Matlab软件上进行多组实验,验证了所提出模型和优化方法的有效性,与按单拣选所需货架搬运次数相比,订单拣选作业优化效果显著。     

用混合蚁群算法求解多工序订单生产计划

高职教育中订单教育模式初探

随着我国开始步入世界制造业大国阶段,许多岗位的技能型人才短缺现象十分严重。作为办学特色鲜明、培养专门技能型人才的我国民办高校高等职业技术教育行业,其“订单教育”人才培养模式出现了强劲的发展势头。但与此同时,也出现了很多的问题,迫切需要进行“订单教育”新模式的探索。本文通过对订单教育的深入剖析,指出了目前订单教育存在的问题,在此基础上提出了新的订单教育模式。     

考虑延迟交货的C2M订单接受决策

以C2M加工装配型制造商在产能约束情形下的订单接受决策问题为研究对象,探讨不同延迟交货率对订单利润的影响。运用约束理论和0-1整数规划法,将企业产能、订单利润、交货期、延迟交货率与订单接受决策相结合,建立了基于产能约束的订单接受决策模型,讨论不同延迟交货率对订单利润的影响;以实现订单利润最大化为目标,通过算例分析对得到的结果进行验证。研究表明,设置适当水平的延迟交货率可以实现订单利润最大化。研究成果可为C2M条件下制造商优化生产管理、完善C2M订单生产决策提供参考。     

思想道德教育与生活方式教育一体化的新构想——新形势下大学生思想道德教育问题和对策设计研究

新形势下大学生的思想及其行为表现出的复杂特性为大学思想道德教育提出了很多新的问题。在功能上存在着重政治轻素质的现象,在形式上存在着重活动轻规划的现象,在内容上存在着重理论轻实践的现象,在研究上存在着重经验轻理论的现象,在队伍上存在着重使用轻培养的现象等,是当前高校思想政治教育中存在的几个突出问题。为了更好地促进我国高校思想道德教育工作的发展,本文结合国外大学生生活方式教育发展的理论与经验,认为我国高校思想道德教育应当充分与学生生活相结合开展全面的生活方式教育,并提出了思想道德教育与生活方式教育一体化的新构想。

WHAT EXPLAINS THE DIFFERENCE IN THE EFFECT OF RETIREMENT ON HEALTH? EVIDENCE FROM GLOBAL AGING DATA

This paper analyzes the reasons for differences in the estimated effect of retirement on health in previous studies. We investigate these differences by focusing on the analysis methods used by these studies. Using various health indexes, numerous researchers have examined the effects of retirement on health. However, there are no unified views on the impact of retirement on various health indexes. Consequently, we show that the choice of analysis method is one of the key factors in explaining why the estimated results of the effect of retirement on health differ. Moreover, we re‐estimate the effect of retirement on health by using a fixed analysis method controlling for individual heterogeneity and endogeneity of the retirement behavior. We analyze the effect of retirement on health parameters, such as cognitive function, self‐report of health, activities of daily living (ADL), depression, and body mass index in eight countries. We find that the effects of retirement on self‐report of health, depression, and ADL are positive in many of these countries.

R&D personnel and human resource management in multinational companies: between homogenization and differentiation

This paper discusses the impact of globalization processes on models of R&D personnel management in multinational companies operating in Europe. Existing literature focuses on the globalization of R&D activity, on the one hand, and on national systems of innovation, on the other. By contrast, there are few studies of the linkage between the globalization of R&D and its impact on HRM. Drawing on the practices of multinationals in four sectors (pharmaceuticals, chemicals, computer hardware and software), the paper examines whether the hold of national differences in the area of HRM has been significantly weakened in the face of new models of competitiveness and management in multinationals. It focuses on two dimensions: recruitment and mobility. The studies highlight two major trends. The ‘internationalization’ of R&D clearly has effects on HRM models but not as great as might be expected. HRM policies such as recruitment and pay systems continue to be nationally based, reflecting legal and institutional differences. At the same time, in conjunction with new forms of R&D organization such as projects, the standardization of HRM tools may be observed. But this is partial and affects only a limited number of tools, notably individual evaluation.     

Sixty years of research on technology and human resource management: Looking back and looking forward

Technology has changed the way we work and how companies manage their employees. This article reviews 60 years of research on the relationship between technology and human resource management, as represented in Human Resource Management. Based on 154 articles, we identify recurring and evolving patterns of research on technology across three time periods (separated by the advent of the personal computer in 1977 and by the popularization of consumer internet services in 1997), three perspectives on technology (tool, proxy, and ensemble view of technology), and three thematic streams (the impact of technology on jobs and organizations, the utilization of technology in HR activities, and the management of technology workers). Drawing on patterns of research that emerged in the past, we provide suggestions for future HR research on newly arriving technology.     

Innovation diffusion: research agenda for developing economies

This paper reviews the literature on innovation to build an agenda for research on innovation diffusion in developing countries. The main ideas on innovation diffusion are discussed, aiming at identifying the key aspects that determine the introduction and development of new technologies in an economy. Analysis of the literature suggests that innovation diffusion depends on three contextual aspects that are economy and government, technology strategies of firms, and management of innovation. Based on this analysis, four areas for research on the subject are identified, aiming at increasing the knowledge about mechanisms and approaches of innovation diffusion in developing countries.

Historical family structure as a predictor of liberal voting: Evidence from a century of Russian history

Family structure is considered a particularly important predictor of social and political development; historical differences in family size and other family characteristics cast a long shadow over societal development. This paper explores the effect of differences in historical family size on political behavior based on within-country variations in this characteristic in Russia. Unlike most papers on historical legacies, we trace the effect of family size over a century of Russian history with a focus on the first competitive and free elections in Russia—to the Constituent Assembly—held in 1917 and on the presidential elections in post-Soviet Russia in 1996 and 2000. Mean family size is measured based on the census data for 1897. We find a robust and significant association between smaller family size and a voting preference for parties that are economically liberal, which holds despite differences in the political, economic, and social environment between the 1910s and 1990s
