A Novel Counter Sheet-Flow Sandwich Cell Culture Device For Mammalian Cell Growth In Space

Cell culture and growth in space is crucial to understand the cellular responses under microgravity. The effects of microgravity were coupled with such environment restrictions as medium perfusion, in which the underlying mechanism has been poorly understood. In the present work, a customer-made counter sheet-flow sandwich cell culture device was developed upon a biomechanical concept from fish gill breathing. The sandwich culture unit consists of two side chambers where the medium flow is counter-directional, a central chamber where the cells are cultured, and two porous polycarbonate membranes between side and central chambers. Flow dynamics analysis revealed the symmetrical velocity profile and uniform low shear rate distribution of flowing medium inside the central culture chamber, which promotes sufficient mass transport and nutrient supply for mammalian cell growth. An on-orbit experiment performed on a recovery satellite was used to validate the availability of the device.

基于契约的客户需求驱动型供应链分销协调研究

供应链协调在国际供应链管理领域备受关注，是涉及多学科高度交叉、知识广泛集成的前沿热点研究领域。它综合了经济学、管理学、营销学、现代网络及信息科学等技术，通过供应链各利益实体之间竞争、协作，实现供应链整体效益的提升。其作为我国实现产业结构优化升级的重要途径，已经成为企业继自然资源、人力资本后的第三个利润增长源泉。 本论文在深入研究供应链管理、供应链协调及契约理论的基础上，分析指出了供应链契约协调研究发展的趋势。依据该趋势本文主要研究的内容是对当前供应链契约协调理论研究的补充和扩展。本文立足于解决我国供应链管理及协调中诸多实际问题，针对现代市场环境中客户需求个性化、多样性及不确定性的特点，研究了供应链契约的统一框架，方法及技术路线，重点研究了客户需求驱动的供应链分销契约协调问题，建立了不同条件下的契约优化模型，给出基于博弈均衡解的一系列证明，并分析了契约参数对供应链整体及各成员绩效的影响，最后基于SOA架构设计并实现了契约自动协商平台。论文的主要研究内容包括以下4个方面： 1. 建立了多对一供应链、确定性客户需求、完全信息下的契约优化模型。基于多个竞争的制造商和一个独立的、共同的零售商组成的多对一供应链分销过程，在客户需求与零售价线性相关、双方掌握完全信息的情况下，针对零售商的保留利润内生给定的特点，建立了收入共享契约框架下的Stackelberg博弈模型和数量折扣契约、两部费用契约下的契约参数优化模型；分析了契约的不同提供方、契约类型的选择和契约参数的优化对供应链整体绩效及利润在各方分配的影响；证明了当制造商所提供的产品具有高度可替代性时，实际增加了零售商的内生保留利润，即增强了零售商相对于制造商的议价能力，在这种情况下，制造商将更倾向于提供批发价契约而不是较为复杂的契约形式。最后通过数值仿真实验，分析验证了上述理论研究的结果。 2．构建了两阶段供应链、短视客户需求、不对称信息、产能约束条件下的混合契约优化模型。针对由单制造商和单零售商组成的双寡头垄断供应链、基于短视客户需求的报童模型、各方需求预测信息不对称的情况，建立了由预购契约和回购契约组成的改进型回购契约优化模型。通过该契约模型同时实现了协同预测、产能优化和供应链分销协调的目的。通过数值仿真实验，验证了改进型回购契约下的供应链协调。通过风险-利润边际和信息不对称度阐述了两段供应链无效性的原因。 3．建立了三阶段供应链、策略型需求、完全信息下的契约优化模型。在由制造商、零售商和理性客户组成的三阶段供应链结构中，根据理性客户及其对产品需求具有策略性的特点，基于零售商和客户间的理性预期均衡构建了研究策略型客户行为的模型框架。分析了集中式供应链绩效与批发价契约及价格补偿契约下分散式供应链绩效的关系，得出在这些契约协调下的策略型客户需求驱动型供应链分销渠道中，分散式供应链绩效严格优于集中式供应链绩效的创新性结论。 4．构建了基于SOA的契约自动协商平台。综合上述契约优化理论研究结论和已有的研究成果，抽象、封装了包含契约类型和契约参数的契约优化服务模型库。基于面向服务的体系架构（SOA）思想，运用数据挖掘软件Weka细化客户需求类型及供应链环境，采用Web Service技术封装各种契约服务，利用企业服务总线（ESB）提供各服务组件绑定、交互和管理通道，以及通过BPEL建模工具对各种服务进行符合逻辑的编排、重组和发布。通过所构建的契约协商平台，实现了供应链分销过程中契约协商的网络化、自动化、智能化和柔性化。

品牌表现评价反应时与关注特性的关系

The decision making of customers has been a great concern in the field of customer research. Although China has entered the era of brand consumption and development, due to the different understanding of the regarded attributes between companies and customers, the phenomenon of “The awarded products don’t sell well, but the products which sell well can’t get the award.” appears. At the same time there is little research on the relationship between the brand and the customers has been conducted in China now. Traditional research on customer psychology employ questionnaires, depth interview and group discussions as the major methods. In cognitive psychology, the limitation of explicit memory has been revealed by implicit memory; moreover, unconscious cognition and implicit memory can also influence customers' remark of the brand. Therefore, the traditional methods are not accurate enough. Reaction time is an effective way to reveal testing equality, and it can also reveal implicit cognition. Based on the researches intends to investigate the validity of attention attributes in the method of reaction time by questionnaires and time reaction testing of 360 customers in 3 cities, which may, probably, overcomes the limitation of the traditional research methods. The 352 valid samples were analyzed by SPSS. The results showed there was no distinct corresponding relationship between the product attributes and reaction time. The different key attributes from questionnaire importance rating and the shortest reaction time standards were used to regressively analyze the results of customers’ overall rating (such as overall satisfaction,objective quality, recommend intention).The results indicated that the coefficiency of regression of the special attributes chosen from reaction time to overall rating was distinct, while the coefficiency of the special attributes chosen from importance rating to overall rating was not. The main conclusions are: 1. Regarded attributes can be obtained by the reaction time of brand performance rating. 2. Regarded attributes obtained by the reaction time of brand performance rating are more accurate than those by importance rating questionnaires. 3. The brand’s core attributes should includes regarded attributes during the decision making process.
