基于神经网络的物流需求预测——以浙江省长兴县为例

为了寻找城市经济与城市物流之间的内在关系,并为城市物流规划提供必要的决策数据和依据,建立基于神经网络的“城市经济一物流需求”预测模型,对城市物流需求量进行预测。应用人工神经网络模型研究城市经济与城市物流需求之问的内在非线性映射关系,为城市物流需求预测提供了一种新的思路和方法。本文以浙江省长兴县历年经济数据作为模型的信息输入。建立起长兴县物流预测模型,并进行求解。     

浅谈对第三方物流的认识

物流这一概念,随着它对商品生产、流通和消费的影响,日益明显并越来越引起人们的注意。随着现代企业生产经营方式的变革和市场外部条件的变化,“第三方物流”(thirdpartylogistics)这种物流形态开始引起人们的重视。为参与国际竞争,企业必须降低产品的成本(包括生产成本和销售成本),降低库存(包括仓储和运送过程中的库存),增加效益;企业要求准确及时的信息,要求增加整个供应链流程的可视性。第三方物流提供者为企业解决了上述难题,因此,越来越多的企业纷纷选择了这一新兴的物流业务。     

Estimation of Deprivation Level Functions using a Numerical Rating Scale

Evaluating and quantifying human suffering in humanitarian operations offers an innovative and potentially powerful way to assess the performance of humanitarian logistics (HL) and help build optimization models. Previous studies have suggested deprivation cost as a metric and have estimated deprivation cost functions for water using willingness‐to‐pay. Our study proposes deprivation levels, defined as the degree of human suffering caused by lack of access to a good or service, and estimates deprivation level functions using a numerical rating scale. Analyzing data collected from respondents with and without disaster experience, we find that individuals in the latter category estimate deprivation differently from the beneficiaries of disaster relief. Our study demonstrates that deprivation levels can be expressed as logistic growth functions with a typical S‐shape, and that these can be integrated into HL optimization models to better account for human suffering.     

The Role of Media Exposure on Coordination in the Humanitarian Setting

Despite high demand and resource limitations, humanitarian organizations (HOs) typically do not share resources and/or coordinate in the field. While coordination enhances operational performance and saves costs, the general perception is that it dilutes the media attention that individual organizations might receive, and negatively influences their future donation income. In this study, we empirically unveil the impact of media exposure and operational performance on the donations obtained by HOs. Then, based on the empirical results, we develop a stylized model to characterize the structure of preferred coordination policies with respect to an organization's funding source and main mandate. Our findings shed light on the incentives and dynamics that drive behaviors in humanitarian operations and provide insights for policy makers on designing and implementing mechanisms that encourage humanitarian coordination.     

Evaluation of multi-objective optimization approaches for solving green supply chain design problems

This paper evaluates the applicability of different multi-objective optimization methods for environmentally conscious supply chain design. We analyze a case study with three objectives: costs, CO₂ and fine dust (also known as PM – Particulate Matters) emissions. We approximate the Pareto front using the weighted sum and epsilon constraint scalarization methods with pre-defined or adaptively selected parameters, two popular evolutionary algorithms, SPEA2 and NSGA-II, with different selection strategies, and their interactive counterparts that incorporate Decision Maker׳s (DM׳s) indirect preferences into the search process. Within this case study, the CO₂ emissions could be lowered significantly by accepting a marginal increase of costs over their global minimum. NSGA-II and SPEA2 enabled faster estimation of the Pareto front, but produced significantly worse solutions than the exact optimization methods. The interactive methods outperformed their a posteriori counterparts, and could discover solutions corresponding better to the DM preferences. In addition, by adjusting appropriately the elicitation interval and starting generation of the elicitation, the number of pairwise comparisons needed by the interactive evolutionary methods to construct a satisfactory solution could be decreased.

物流专业英语的学习需求分析及启示

需求分析是一种评估研究范畴,可以为改进物流专业英语教学提供依据。本研究中需求分析的抽样调查结果显示,物流专业英语教学中学习者非常关注和强调专业英语的实用性和应用性,而这恰恰是当前物流专业英语教学的"短板"。由此得出改进"语言输入"、重视"语言输出"、优化"评估手段"等改进物流专业英语教学的思路和启示。     

第三方物流外包服务综合绩效评估模型的构建

本文根据全面性、特殊性、可比性、可操作性原则,参考评价第三方物流企业的一般评价指标的选取原则,选取了包括运力资源利用率、固定资产周转率、订单完成率、配送资源利用率等20个具有代表性的指标,详细地构建了第三方企业物流系统综合评价指标体系,并采用主成分因子分析法对企业物流系统进行了综合评价。     

高等院校物流管理专业实习实训方案的设计

随着我国社会经济的不断发展,物流领域出现了专业人才匮乏的现象。在社会对物流人才需求旺盛的情况下,很多高等院校相继开设了物流管理专业,以期通过大量培养物流管理专业的人才来满足相关企业的需求。但是在实践中,很多物流管理专业的学生在实习工作中缺少应变能力,实践能力弱,不能达到物流企业的用人标准。对目前高等院校物流管理专业实习实训方案进行了分析探讨,以期设计出一个相对完善、创新的物流管理专业实习实训方案,促进物流管理人才的培养,有效满足当前物流管理人才供不应求的紧张局面,促进我国整个物流领域更好更快地发展。
