打捆机捆丝剪切刀的有限元分析

随着科技的发展，打捆包装机械在工业当中应用的越来越多，所研究的是针对线材、管材以及棒材进行打捆的这类包装机械（简称打捆机）的剪切刀。阐述了剪切刀在剪切过程中的受力情况以及对其进行有限元分析，为设计打捆机的剪切刀提供了理论依据。     

基于ANSYS的捆丝有限元分析

介绍了钢丝捆钢机的工作原理，利用ANSYS软件对捆丝在导槽中的受力、变形情况进行了分析。得到了捆丝在导槽中与轴承的支反力和变形，可以推出捆丝在导槽中的摩擦力，为进一步分析捆丝送丝力计算提供理论指导。     

信息产品捆绑销售的模型分析

研究了捆绑销售策略对于信息产品销售的影响,分析了运营商的最优捆绑策略.考虑两种常见的捆绑类型——针对单个产品的数量捆绑以及针对多种类型产品的捆绑.在连续消费者类型的假定下,从价格歧视的角度分析了两种捆绑的最优定价以及此时的利润、消费者剩余和社会总福利,给出了两种捆绑销售适用的条件.结果表明:对于单个产品,捆绑销售的效果与消费者类型的差异程度有关;对于多产品,混合捆绑优于纯捆绑和非捆绑销售,并且其效果与消费者对捆绑产品的平均估价和供应商设定的折扣程度有关.结果也说明,在一定条件下,捆绑销售能够给供应商带来更大的利润,但同时降低了消费者剩余,减少了社会总福利.     

小议信息商品的定价

介绍了3种形式的价格歧视,并分析了一种比较流行的价格歧视——捆绑定价。     

产品售后服务捆绑销售与营销策略演化

产品的售后服务已成为影响消费者购买行为不可忽视的因素,企业通常会采取捆绑销售或单独销售的方式向消费者提供更优质的售后服务.考虑消费者的异质性并引入竞争导向型企业,通过构建Hotelling以及复制子动态演化博弈模型分析企业短期均衡价格以及长期演化稳定的销售策略.研究发现:较高的售后服务成本会促使一方采取捆绑销售策略并使得双方均获益,捆绑销售策略将与单独销售策略共存;非基本消费者比例越高单独销售策略越有利,单独销售策略将成为最终的演化稳定策略;相比较竞争导向型的企业而言,利润导向型企业更倾向于选择捆绑销售策略;仿真分析表明高售后服务成本下采取跟随策略的非理性企业会被淘汰,而在低售后服务成本下这一类型企业将会存在于市场上.     

新产品捆绑上市的鲁棒定价策略

面对新产品信息缺失的上市困境,从传统的供应链合作上市向产品合作上市推进,根据成熟产品和新产品信息的不同,探讨了零售商的四类上市策略,旨在发现哪种策略更有利于新产品推广.研究表明,当两产品捆绑后具有一定互补性时,"捆绑上市+部分信息"策略下零售商的利润完美地逼近"捆绑上市+完全信息"策略,远高于"单独销售+完全信息"策略,凸显了产品合作的价值,使得零售商无需获得新产品的所有信息,就能有效推进新产品成功上市.     

Bundling strategies for platforms with an installed base

As an emerging platform, hardware/software platforms differ from traditional retail platforms because they require consumers to spend a certain amount of money accessing them. Therefore, an installation base is created. Considering the game console as an example, only consumers with an installation base can purchase a third-party game product on the platform. Otherwise, consumers will be unable to play games. It is generally believed that the existence of an installed base will benefit third-party content providers, and at the same time, it will not benefit platform manufacturers. Therefore, it can be observed that game platforms often bundle new consoles with third-party content, forcing consumers with installed bases to purchase a new console. Thus, building a model to study the impact of the installation based on the bundling strategy of the video game platform and to analyze the optimal pricing and profit under different bundling strategies is meaningful. Our study analyzed the impact of the installed base under different bundling strategies and found that the installed base dose not always have a positive impact on platform manufacturers. The study also analyzed the equilibrium of competing platform manufacturers and found that, under certain conditions, both the bundling-bundling strategy and the unbundling-unbundling strategy may exist as equilibrium.     

钢丝类捆钢机送丝力研究

首先根据捆钢机捆扎工艺及过程对捆扎材料进行选择,确定了捆钢机种类。然后,详细分析了捆丝在送丝导槽中穿行所需初始送丝力以及实际送丝力,为捆钢机驱动系统设计提供了理论依据。     

SideKnot:Edge Bundling for Uncovering Relation Patterns in Graphs

The node-link diagram is an intuitive way to depict a graph and present relationships between entities.Addressing the visual clutter induced by edge crossing and node-edge overlapping is a challenging task as the size of graph outgrows the visualization space.Many edge bundling methods are proposed to disclose high-level edge patterns.Though previous methods can successfully reveal the skeleton graph structure,the relation patterns at the individual node level can be overlooked.In addition,most edge bundling algorithms are computationally complex,which prevents them from scaling up for extremely large graphs.In this article,we extend SideKnot,an efficient edge bundling method to cluster and knot edges at the node side.Our proposed method is light,runs faster than most existing algorithms,and can reveal the relation patterns at the individual node level.Our results show that SideKnot can disclose a node’s standing in the graph as well as the directional connection patterns to its peers.
