基于Internet的协同产品概念设计   总被引:1,自引:1,他引:1  
产品概念设计是决定产品最终成本和创新程度的一个非常关键的阶段,在基于Internet的协同产品概念设计需求分析的基础上,提出了支持协同产品概念设计的总体框架,并分析了各个模块的作用及相互关系.基于这一支持框架,进一步提出了从概念生成、概念交流,到最佳产品概念选择这样一个包括三个阶段的协同产品概念设计模型,从整体上论述了协同概念设计过程的实现.本文提出的协同产品概念设计的总体框架和设计过程模型为实现产品的快速开发和创新设计提供了有效的支持和实现模式.  相似文献

This paper investigates the resilience of inventory models using interconnected logistics services in the Physical Internet (PI). With traditional supply chain network design, companies define and optimise their own logistics networks, resulting in current logistics systems being a set of independent heterogeneous logistics networks. The concept of PI aims to integrate independent logistics networks into a global, open, interconnected system. Prior research has shown that new inventory models enabled by and applied to PI could help reduce inventory levels thanks to its high flexibility. Continuing along these lines, this paper examines how inventory models applying PI deal with disruptions at hubs and plants. To attain this, a single product inventory problem with uncertain demands and stochastic supply disruptions is studied. A simulation-based optimisation model is proposed to determine inventory control decisions. The results suggest that the PI inventory model, with greater agility and flexibility, outperforms the current classic inventory models in terms of resilience. Moreover, the difference in performance increases when the product value, penalty costs and disruption frequency increases. This paper indicates a novel approach to build a resilient supply network.  相似文献

Horizontal and vertical integration of engineering education is achieved through an early‐design project where students get acquainted with Total Quality Management (TQM) principles and design processes from year‐one of their University education. The project is embedded in the undergraduate chemical engineering curriculum as an activity that involves horizontally several first‐year subjects and vertically a fourth‐year Project Management Practice course and a related Project Management subject. An assessment of the integrated design project indicates that effective teaching and learning spreads through the curriculum, with fourth‐year students acting as project managers and experiencing engineering practice. These management and leadership training processes include a shared responsibility in the organization and in the development of the project, which are key factors for the success of the integrated activity. They are also a first step towards the ETSEQ goal of becoming a sustainable student‐centered educational system.  相似文献

The Physical Internet concept was developed to address the current unsustainability problem of logistic systems. The key elements are the encapsulation and the handling of world-standard smart green modular containers (π-containers) throughout an open global logistic infrastructure. Logistic processes such as partial loading/unloading or splitting/merging of π-containers play an important role for a successful Physical Internet. However, the large variety of transformation processes can introduce desynchronisation between the physical and informational flows, i.e. the real composition of a composite π-container (a set of stacked π-containers) can differ of the information stored in the supply chain management system. To overcome this problem, this paper proposes a system to generate and maintain automatically a virtual three-dimensional layout reflecting the spatial distribution of π-containers. The proposed approach uses smart π-containers equipped with wireless sensor nodes. The relative position of π-containers can be determined by the neighbourhood relationships between the sensor nodes. From this information, a constraint set is formulated in a Constraint Satisfaction Problem where each solution is a potential loading pattern. The methodology is developed and computational experiments are proposed, as a proof-of-concept. The results show that our proposed method yields quick and satisfactory results.  相似文献

The collaboration in Europe for research in superconductivity, especially for large Scale applications, has a long tradition. In the early seventies already a so-called "GESSS group" (Group on European Superconducting System Studies) became active for accelerator and detector magnet development. In the second half of the seventies the fusion technology programme in Europe called for an increasing effort in magnet development. Due to the fact that the fusion work is at all a collaborative European effort and the earlier GESSS laboratories got involved in that area too, these activities were carried out jointly from the beginning. Participation in the IEA-Large Coil Task by two European groups also proved the capability of an even broader international collaboration. Based on the different management schemes for the collaborations lessons have been learned and are discussed, which might be valuable for foreseeable large European projects such as NET (Next European Torus) and LHC (Large Hadron Collider) in the next decade. The role of industry as a collaboration partner in the different areas is discussed, too.  相似文献
