自动化立体仓库中的储位分配及存取路径优化

储位分配和存取作业路径优化是仓储管理中的两个重要决策问题。本文研究如何在自动化立体仓库中对这两个问题进行同时决策。提出了一个混合整数规划模型对该问题进行优化建模,设计开发了一个基于有向连接图的两阶段优化算法对问题求初始解,并利用禁忌搜索算法对所求得的解进行改进。算法第一阶段解决储位分配问题,在此基础上第二阶段利用Hungarian算法对堆垛机的存取作业路径优化问题进行求解。最后利用实例对算法效率和精度进行分析评价,计算结果验证了算法的有效性。     

团队薪酬、任务互依性对团队绩效的影响研究

本文回顾了团队薪酬的研究现状,总结了团队薪酬计划的典型模式,对比了两种一次分配方案(线性预算计划和竞争线性计划)和两种二次分配方案(平等型和公正型)的激励效果,并进一步比较了在不同任务互依情境下激励效果是否存在差异。运用2×2×2的实验设计进行假设检验,组织141名被试以三人团队形式参与一项汉字检索任务。结果表明,竞争线性计划对团队绩效的激励效果优于线性预算计划,并且这种优势在低任务互依情境下更为显著。二次分配方案的激励效果在不同的任务互依情境下存在显著差异:在低任务互依情境下,公正型二次分配对团队绩效的激励效果更好;在高任务互依情境下,平等型二次分配对团队绩效的激励效果更好。     

关于区域税收与税源背离问题的思考

由于现行税收制度体系设计和生产经营活动复杂性等原因,合理有效解决区域间的横向税收分配问题,缓解区域间税收与税源的背离程度,促进经济社会公平、健康、和谐发展,成为我们当前需要研究和探讨的问题。本文基于政府间税收分配理论对区域间税源背离的一般性问题进行探讨,并提出相应的建议。     

基于优先权拍卖的产能分配机制研究

本文考虑一个供应商和两个独立零售商构成的供应链系统。当供应商的产能受到约束时,零售商可能会竞争有限的产能。本文提出将“优先分配权”作为一个有价值的标的物进行拍卖,按照出价高低确定优先分配顺序。本文证明了优先权拍卖机制属于共同价值模型,并提出了两类拍卖机制：事先拍卖和事后拍卖。本文证明两类优先权拍卖机制均会促使零售商提交真实的需求作为订单量,并且满足收益等价定理。而就供应商期望利润而言,事后优先权拍卖机制要高于事先优先权拍卖机制。     

工程质量政府监督多层次利益分配与激励协同机制探究

The implementation of the government supervision of the quality of the project is an international practice. The basic form of government supervision of engineering quality is government supervision on the quality behavior of the engineering main bodies and its results by the competent government department entrusted. Its essence is a dual principal-agent process. The frequent accidents of the engineering quality reflect the loss and failure of the government law enforcement supervision of the engineering quality to some extent. Its root lies in the lack of endogenous power in the law enforcement supervision of the project quality government supervisors in the law enforcement supervision. Therefore, the incentive coordination mechanism of the government supervision based on the multi-level interest distribution is worth explored. In views of the multi-level management system which is formed by the government departments, government quality supervision organizations, quality supervision team (or group) for the government supervision of engineering quality. The benefit distribution function between every party is constructed, and the game model of the multi-level incentive and coordination for the government supervision in engineering quality is built. To solve and deduce from the first stage of the cooperative game and the second stage of the non-cooperative game, the cooperative game can obtain the reward coefficient: . The coordination degree of the best effort can be obtained by the non cooperative game. The result shows that:the coordination degree of government engineering quality supervisor is related to the coordination costs, and had nothing to do with fixed costs. The benefit distribution coefficient not only depends on the efforts of the quality government monitors, but also on the efficiency of other parties' efforts. The quality supervisors of the project will also focus on the coordination with other parties when enhancing their management capabilities to improve the overall performance of project quality government supervision. The strategy of the incentive coordination mechanism for the supervision and cooperation of the project quality government is:the government quality supervision team should set up the supervisory team properly, improve the coordination efficiency and reduce the cost of supervision-coordination to maximize the value of self-motivation. Quality supervision team (or group) should establish the partnership to improve the coordination efficiency for achieving the maximization of their own incentive value.The model and conclusion of incentive synergy mechanism based on multi-level benefit allocation mechanism are researched. It can provide theoretical support and practice reference for the market governance and supervision of general public goods.

库兹涅茨收入分配假说与我国现实

库兹涅茨收入分配的假说从逻辑上看有一定的合理性,但不一定是经济规律。一国的国情不同,收入分配的变化规律自然会有不同,我国的收入分配状况有特殊性,必须充分认识我国社会收入分配过大差距的危害。     

产业工资集体谈判改善收入分配的条件与启示——以美国为例

美国产业工资集体谈判对收入分配影响的演变说明,不仅制度因素,市场因素更直接影响产业工资集体谈判实效。在经济全球化背景下,我国大部分产业的市场结构和在国际市场上的竞争力制约着产业工资集体协商达到普遍改善雇员企业收入分配地位的目标。面对民营企业雇员集体诉求的增加,政府和总工会应分类协调,寻找协调民营企业集体劳动关系的务实路径,慎重地以行政力量推进产业(行业)工资集体协商。     

数字经济环境下营业利润课税权的分配

数字经济环境下企业从事跨国经营活动方式的革命性变化,对建立在传统理论基础上的现行营业利润征税权分配原则的适用提出了严峻的挑战。基于对数字经济环境下营业利润的贡献要素分析,对跨境数字化交易利润的征税权分配,不宜适用现行的常设机构原则,而应改行税收分享原则,由销售市场地国按税收协定规定的限制税率源泉扣缴预提所得税,以有效扼制数字经济诱发的税基侵蚀和利润转移国际避税现象的泛滥,进而实现跨境数字化交易利润国际税收权益分配的公平合理。
