多中心共同配送与收集网络联盟优化问题研究

针对多中心共同配送与收集网络中物流合作联盟构建和收益分配机制设计方面存在的不足,提出了多中心共同配送与收集网络联盟优化策略。首先,建立了网络运营总成本最小和配送与收集车辆使用数量最少的双目标优化模型。其次,提出了结合k-means聚类算法和Im-NSGA-Ⅱ算法的混合启发式算法求解模型,该混合算法通过引入贪婪求解思想和精英保留策略,提高了算法的全局收敛性能和局部寻优能力,并与NSGA-Ⅱ和MOGA算法进行对比分析,验证了所提算法的有效性。然后,运用最小费用剩余节约方法(MCRS)研究多中心共同配送与收集网络联盟的收益分配问题,并讨论合作联盟序列选择和联盟稳定性。最后,通过实例对提出的优化模型和算法进行验证。结果表明,该方法能够优化多中心共同配送与收集网络资源配置,降低网络运营成本,为多级共同配送与收集网络优化提供参考和方法借鉴,并为可持续的城市物流网络规划和共享物流合作联盟构建提供决策支持。

Ethics and Its Relations With Education and Research

Brazilian studies in （Critical） Applied Linguistics＇ field have being carried out focusing on ethics. They focused on the relation between ethics and two main contexts： education and research. This paper aims at discussing what ethical procedures were taken in international studies. The data were collected at ERIC （Educational Resources Information Centre） database during the first semester of 2016. As analytical categories, we used the ethical procedures established by Brazilian Applied Linguists. The contribution is addressed to both BAL and International Applied Linguists once it offers an overview about a specific topic of research （viz., ethics）. As results, we observed that most of the topics presented by the Brazilian applied linguists were also covered by the research analyses. However, the social relevance was not reported properly by the data and that may be improved.
