双渠道运营以提高顾客的购买体验为核心,不仅要求各渠道建立合理定价策略,同时要实现渠道间协同,这放大了制造商与零售商之间乃至整条供应链的冲突,进一步刺激链外企业进入行为,从而加剧在位制造商采取阻止策略.基于链外进入行为的普遍性与在位阻止的现实性,研究结果表明：当进入成本较低时,在位制造商无法阻止外来制造商进入;当进入成本过高时,在位制造商不用改变定价即可阻止进入;而当进入成本适中时,在位制造商可以通过降低产品在直销渠道上的零售价达到阻止进入的目的.同时结合数值计算得到了一些管理启示.

预售期到达的策略消费者与制造商之间产品质量信息不对称,制造商可以通过不同的预售策略和预售价格设置,影响消费者对产品质量的判断和购买时机的选择.基于信号传递博弈理论,构建产品质量信息对称和不对称时的博弈模型,给出质量信息不对称时制造商实现分离均衡和混同均衡的边界条件.结果表明:制造商产能较大时,期权预售本身可以作为高产品质量制造商的信号传递工具;消费者判断产品质量为高质量的先验概率足够大时,高产品质量制造商倾向于实现混同均衡隐藏质量信息,反之倾向于实现分离均衡,通过较高的行权价格传递质量信息.最后进一步探讨预售期时长对消费者等待成本的影响,结果表明等待成本相对较低时上述结论依然成立.

全渠道运营以提高顾客的购买体验为核心,不仅要求各渠道保持自身高服务水准,同时要实现渠道间服务协同,这放大了战略制造商与零售商之间乃至整条供应链的冲突,进一步刺激了顾客的等待行为,从而加剧产品供给与需求间的不匹配性。本文基于战略顾客行为的普遍性与全渠道竞争的现实性,对近年来大数据驱动下的全渠道供应链服务创新及其关联因素进行综述,构建基于大数据驱动下全渠道供应链服务创新的决策框架,利用贝叶斯网络方法分析大数据驱动下的服务创新能力,以期为服务创新优化决策提供支持。

顾客多渠道之间选择购买,分散了传统零售渠道的客流,降低了零售商的影响力。这两类冲突会降低零售商的销售热情,影响分渠道销售能力,甚至可能引起恶性竞争。文章基于消费者效用理论,探讨零售商努力行为能否引导消费者提前购买商品和缓解渠道冲突。通过不存在零售商努力和存在零售商努力情形下的研究表明：在战略顾客下跨渠道供应链中,零售商采取努力行为,不仅能使战略顾客提前购买,且能使制造商和零售商获得更好的收益。由此以制造商为主导的跨渠道供应链应关注实体店的努力行为以缓解渠道冲突并实现制造商与零售商的互利共赢。

探讨了质量信息不对称下制造商与零售商联合披露、制造商披露以及零售商披露3种披露方式下的双渠道定价策略,得到不同披露方式下的质量信息披露条件。结果表明:3种披露方式下的质量信息披露阈值都与披露成本、交叉价格弹性、渠道的潜在需求量相关,且披露成本越大,质量披露的动机就越小。同时借助于数值分析发现,当产品质量较低或较高时,零售商披露方式最优;当产品质量中等时,制造商披露要相对优于零售商披露,但只有联合披露可以使双渠道供应链系统达到最优状态。

Acta Oceanologica Sinica 2019年第1期38卷 112-117页

作者： Si Tuan Vo Thai Tuyen hua kim Hoang Phan Institute of Oceanography Vietnam Academy of Science and Technology

The Province of Khanh Hoa, Vietnam, is located in the western South China Sea and boasts a shoreline of 385 km and many islands. Previous studies have indicated the extreme diversity and abundance of coral reefs in its waters as compared with other coastal provinces of Vietnam. A study on the resilience of coral reefs against increased surface water temperature and anthropogenic impact is conducted at 19 reef sites in 2015. At each site, a series of parameters(e.g., coral covers, genus diversity, and coral recruitment, substratum heterogeneity, depth, water exchange level, and sediment deposit and water temperature) are measured quantitatively or *** measured data are rated based on the relationship between the parameter values and coral susceptibility; the consideration that reef health reflects the biological capability to adapt to environmental changes and the recruitment potential if bleached; and positive or negative influences of physical factors in the mitigation of thermal stress and protecting corals from bleaching. A cumulative analysis enables researchers to divide the studied reefs into four categories based on varying levels of reef health to support resilience, recovery, and vulnerability in the case of increased water temperature. Relevant management interventions for each category and other supporting activities are suggested to enhance management effectiveness and to plan the rehabilitation of coral reefs for biodiversity conservation and touristic development, taking into account the involvement of related stakeholders.

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2007年第10期8卷 1671-1680页

We give the topology changing of the silhouette in 3D space while others study the projections in an image. Silhou- ettes play a crucial role in visualization, graphics and vision. This work focuses on the global behaviors of silhouettes, especially their topological evolutions, such as splitting, merging, appearing and disappearing. The dynamics of silhouettes are governed by the topology, the curvature of the surface, and the view point. In this paper, we work on a more theoretical level to give enu- merative properties of the silhouette including: the integration of signed geodesic curvature along a silhouette is equal to the view cone angle; in elliptic regions, no silhouette can be contained in another one; in hyperbolic regions, if a silhouette is homotopic to a point, then it has at least 4 cusps; finally, critical events can only happen when the view point is on the aspect surfaces (ruled surface of the asymptotic lines of parabolic points with surface itself). We also introduce a method to visualize the evolution of silhouettes, especially all the critical events where the topologies of the silhouettes change. The results have broad applications in computer vision for recognition, graphics for rendering and visualization.
