The Third-Party Logistics Services and Globalization of Manufacturing

Cross-border production chains of manufacturing require coordination and logistics. Third-party logistics services have thus taken this role as a link in the globalization of economic activities. Distriparks, a provider of total logistics to manufacturing, have emerged in Singapore to offer customized distribution and inventory management. Established as a traditional entrepôt by international trading, the city-state has revamped its distribution industry when transnational corporations come to choose Singapore as regional centre and local firms venture into the region. Distribution has regained its vitality in the global economy. It is demonstrated that distriparks have facilitated the restructuring of Singapore manufacturing and altered the internal structure of firms in their space utilization. Thereafter, a changing profile of industrial landscape, high-density industrial land use, and industrial agglomeration ensues.     

三维参数化CAD技术在大型钢桥设计中的应用

目前用于机械设计的三维参数化软件比较成熟,但没有专门用于桥梁设计的此类软件。对于常见的公路或铁路钢桥设计,具有以下特点:体量大,零件多,采用标准件少,零件之间具有复杂的几何关系,许多零件需要在装配中确定其尺寸,但单个零件的几何形状又比较简单,多由板材、角钢等切割拼接而成等。这就使得将用于其他领域设计的软件,原封不动地移植过来进行钢桥设计存在一定困难,必须进行二次开发。介绍了将三维参数化CAD设计技术应用于大型钢桥设计的经验,并结合平台,介绍了使用API进行二次开发的基本原理和方法。

Non‐Waste‐Wachsschalungen: Neuartige Präzisionsschalungen aus recycelbaren Industriewachsen

Non‐Waste wax formwork‐technology Today's possibilities to realize complex free‐form reinforced concrete shapes, curved walls and filigree details require a formwork technology which meets these challenges. High precision with maximum freedom of form is therefore an essential requirement for the formwork of this new, so‐called freeform architectures. Preconditions for this are the 3D digital design and manufacturing technologies, with their help formwork can be designed and manufactured in high precision and with many degrees of freedom in form. This paper describes a research approach using industrial waxes as formwork materials. Due to the nearly 100 % recyclability of the wax, this approach is an economical and ecological manufacturing process for customized free‐form‐members made of concrete.     

Key practices,manufacturing capability and attainment of manufacturing goals: The perspective of project/engineer-to-order manufacturing

Project manufacturing or engineer-to-order (ETO) manufacturing is an operation designed to provide unique but similar products. For ETO manufacturing, every product is the ultimate result of a project. In addition, unique orders may be managed like a project. The primary purpose of this study was to validate a model for assessing the relationships among manufacturing practice, manufacturing capability, and attainment of manufacturing goals from the perspective of project manufacturing. The analyses suggest that implementation of manufacturing practices in terms of production planning, quality management, human resource management, and capacity management may improve manufacturing capability. The results also imply that manufacturing capability may enhance attainment of project manufacturing goals. Furthermore, the findings indicate that stability of supplier's manufacturing acts as a moderator between manufacturing practice and manufacturing capability. Finally, the positive association between manufacturing capability and attainment of project manufacturing goals depends on process maturity, complexity, time availability, and team size.     

Internal relationship modeling and production planning optimization for the manufactured housing

The ‘manufacturer-internal relationship optimization model (MIROM)’, a schematic framework for internal relationship, is proposed for the manufactured housing (MH) factory. This model emphasizes the relationship between customer order from retailers (i.e., customized MH) and the production process, indicating that these elements are not mutually exclusive. In particular, through surveys and site visits, the planning of the product mix and sequence in the MH factory is considered the most critical area of the MIROM framework. This paper aims to convey how these areas can be elevated to the planning level with innovative changes and optimization. A product mix optimization model with linear programming was developed and a sequence optimization model was created by incorporating just-in-time (JIT) approaches. The proposed strategic MIROM framework and the specific optimization models can contribute to achieving significant improvement in the internal MH production planning. It can be applied for the site-built housing industry with similar industrialized environments depending on the scale of the operation.

Simulation of Legionella concentration in domestic hot water: comparison of pipe and boiler models

The energy needed for the production of domestic hot water (DHW) represents an important share in the total energy demand of well-insulated and airtight buildings. DHW is produced, stored and distributed above 60°C to kill Legionella pneumophila. This elevated temperature is not necessary for DHW applications and has a negative effect on the efficiency of hot water production units.

In this paper, system component models are developed/updated with L. pneumophila growth equations. For that purpose, different existing Modelica pipe and boiler models are investigated to select useful models that could be extended with equations for simulation of bacterial growth. In future research, HVAC designers will be able to investigate the contamination risk for L. pneumophila in the design phase of a hot water system, by implementing the customized pipe and boiler model in a hot water system model. Additionally it will be possible, with simulations, to optimize temperature regimes and estimate the energy saving potential without increasing contamination risk.
