Die Baugesellschaft Gebrüder Rank und ihre spanischen Ziegelgewölbe in München

The Rank construction company and the introduction of brick vaults in Munich after 1945 The construction of vaults without scaffolding with thin bricks has a centuries‐old tradition, particularly in Spain and Italy. Since the beginning of the 19^th century, it has been successfully spread mainly on the American double continent. The Rank Brothers construction company in Munich is known to date as one of those construction companies that began building with concrete in its home city very early on. New investigations, which were made possible above all by the provision of archive material by Paul Basiner, now point to an additional focus of this company's work. The architects and engineers of the company had been also able to familiarise themselves with this traditional Spanish brick‐vaulted construction method via the branch office in Spain, which was established from 1911 on. This knowledge was particularly in demand in the years following World War II, when the destroyed vaults had to be rebuilt with simple means and low material consumption. Together with Carl Sattler, who had become acquainted with similar construction methods in Italy, brick vaults were initially used to complete the construction of the Landeszentralbank in Munich. In the following years, Rank was able to provide many buildings in and around Munich with brick vaults. It was not until the 1960s that this construction technique went out of fashion and was thus somewhat forgotten.     

防差错系统在软胶囊生产中的应用

随着制造执行系统(manufacturing execution system, MES)在汽车制造业中的广泛运用, 越来越多的行业开始导入MES系统。我国保健食品行业发展迅速, 市场规模不断扩大, 越来越多的企业将MES系统导入到生产过程中, 目前绝大多数企业只停留在MES系统的初级阶段, 用于物料、容器具和人员的追踪等。我司在MES系统的基础上, 对软胶囊生产进行防差错系统开发, 将防差错系统与MES系统全方面的结合, 并运用到软胶囊生产过程中。通过对软胶囊生产工艺分析, 确定各个环节的质量风险点, 增加探头感应器、扫描枪、编程, 赋予设备与物料条形码, 实现配料化胶、压丸、干燥选丸防差错系统的开发。防差错系统的开发应用, 减少了软胶囊生产过程的质量风险点, 避免人为因素带来的质量偏差, 实现生产过程中的局部自动化, 为实现软胶囊连线生产奠定了扎实的基础。     

Distributed ledger technology in supply chains: a transaction cost perspective

With the emergence of distributed ledger technology (DLT), numerous practitioners and researchers have proclaimed its beneficial impact on supply chain transactions in the future. However, the vast majority of DLT initiatives are discontinued after a short period. With the full potential of DLT laying far down the road, especially managers in supply chain management (SCM) seek for short-term cost-saving effects of DLT in order to achieve long-term benefits of DLT in the future. However, the extant research has bypassed grounding long-term as well as short-term effects of DLT on supply chain transaction with empirical data. We address this shortcoming, following an abductive research approach and combining empirical data from a multiple case study design with the corresponding literature. Our study reveals that the effects of DLT on supply chain transactions are two-sided. We found six effects of DLT solutions that have a cost-reducing or cost avoidance impact on supply chain transactions. In addition, we found two effects that change the power distribution between buyers and suppliers in transactions and a single effect that reduces the dependency of supply chain transactions on third parties. While cost-reducing and avoidance as well as dependency-reducing effects are positive effects, the change in power distribution might come with disadvantages. With these findings, the paper provides the first empirical evidence of the impact of DLT on supply chain transactions, which will enable managers to improve their assessment of DLT usage in supply chains.     

基于Agent的信任的情感劝说决策模型

基于智能体(Agent)的信任的情感劝说能更好地发挥Agent的各项人工智能优势。针对其中决策模型建立不够的现状,首先基于Agent的自身性格、情感衰减及外界刺激,运用大五性格、OCC情感模型及情感强度第一定律等,构建了相应的情感强度算法;其次考虑交易质量对信任的反馈,综合运用语言评价法、三角模糊数及将模糊数转换为具体分数(CFCS)算法,对Agent的交易质量进行模糊化和去模糊化处理,构建了相应的交易质量算法;再次对已有的信任更新因子进行改进后,构建了Agent的信任更新算法;最后在构建以上算法的基础上,采用交互式多准则决策(TODIM)法建立了基于Agent的信任的情感劝说决策模型,并采用熵权法对模型中的属性权重进行设定。为验证以上研究的合理性和有效性,设计了相应算例进行阐述,分析了不同参数取不同值得到的决策结果,并与相关研究进行了比较分析,得出了相应结论和管理启示,进一步归纳了不足之处和未来研究方向。     

A Novel Mechanism for TRF of Plant-wide Material Flows in Process Industry MES

This paper is standing on the recent viewpoint originated from relevant industrial practices that well or-ganized tracing, representing and feedback （TRF） mechanism of material-flow information is crucial for system utility and usability of manufacturing execution systems （MES）, essentially, for activities on the side of multi-level decision making and optimization mainly in the planning and scheduling. In this paper, we investigate a key issue emphasized on a route of multi-level information evolution on the side of large-scale feedback, where material-flow states could evolve from the measuring data （local states） to networked event-type information cells （global states） and consequently to the key performance indicators （KPI） type information （gross states）. Importantly, with adapta-bilities to frequent structural dynamics residing in running material flows, this evolving route should be modeled as a suit of sophisticated mechanism for large-scale dynamic states tracking and representing so as to upgrade accu-racy and usability of the feedback information in MES. To clarify inherent complexities of this evolving route, the investigated issue is demonstrated from extended process systems engineering （PSE） point of view, and the TRF principles of the multi-level feedback information （states） are highlighted under the multi-scale methodology. As the main contribution, a novel mechanism called TRF modeling mechanism is introduced.     

Untersuchung von Schlosssprengungen an ausgeführten Ufereinfassungen mit kombinierten Spundwänden

Interlock failure of combined sheet pile walls In addition to multiple combinations of king piles and intermediate sheet piles the installation method of combined sheet pile walls can differ as well. The installation has to adapt to the boundary conditions of the construction work considering soil conditions, profile and interlock system, interlock protection, driving equipment, driving assistance etc. Despite the established construction of combined sheet pile walls interlock failure occurs. In this paper, the installation aspects of combined sheet pile walls in northern Europe are compiled and analyzed for the occurrence of interlock failure.     

Ausbau des Stichkanals nach Salzgitter von SKS‐km 3,550 bis 14,918

Expansion of the branch channel to Salzgitter from SKS‐km 3,550 to 14,918 The branch channel to Salzgitter will be extended to the waterway category Vb in the next years. This will enable inland waterway vessels with a width of 11,45 m and a loaded draft of 2,80 m to run it without limitations. The reaches Wedtlenstedt and Üfingen will be extended in most areas to a trapezoidal cross section with a width at water level of 36,90 m and a water depth of 4,00 m. The exit basins of the locks will be extended on one side. Overall about 1 000 000 m² of soil will be moved. About 300 000 m² of clay sealing and 460 000 m² of rip‐rap will be installed. Three culverts have to be replaced by new constructions to adapt to the new cross section of the channel. In addition two bridges will be modified to allow for a clearance of 5,25 m. At present the plan approval procedure is carried out. It is expected to achieve the plan approval order in 2017. The construction is planned to start in 2018. Completion is scheduled for 2024.

农村工业化地区的城市更新:从破碎到整合——以佛山市南海区为例

空间破碎是农村工业化地区实施城市更新的主要制约,如何整合是重要的实践和学术课题。本文以“问题-对策”为分析框架,以佛山市南海区为例,从广度层面揭示出三类空间破碎及其对改造的约束机理和现有改造的整合特征,并通过深度的案例比较探究空间整合的关键所在。研究发现:物质和权属的空间破碎是该类地区的典型特征,改造又衍生出政策空间破碎;破碎增加交易成本,阻碍用地整合;现实中的整合改造是少数;在市场资本的驱动下,政府推动整合的效果显著。以“交易中间人”的角色统筹改造彰显出政府降低交易成本以协同市场的职能回归。
