Egyptian pyramid or Aztec pyramid: How should we describe the industrial architecture of automotive supply chains in Europe?

This article questions a terminology that is frequently used to describe automotive supply chains’ industrial architecture. Since vertical disintegration became a trend in the 1980s, this architecture has been represented using the image of the pyramid. Implicitly, authors have had the image of an Egyptian pyramid in mind, one that is pointed at the top and broad at the base. We will demonstrate that even if pyramids are an appropriate image, in the auto industry the Aztec variant, with its shortened peak and room for SMEs, is more accurate. The paper’s first section – with its more historical focus – explains the birth of the Egyptian pyramid. The section 2 puts forward the idea that the Egyptian metaphor is more misleading than informative. We start by demonstrating that overusing this metaphor will ultimately exclude a number of very strategic companies from analysis. This is followed by a presentation of the findings from a study of 750 French SMEs*, in which it is demonstrated both that some continue to maintain direct access to carmakers and also that the hierarchy of tiers comprising this supply chain features greater porosity than is commonly recognized.modularity, supply chain, industrial architecture, SME, automobile.

The learning network on sustainability: An e-mechanism for the development and diffusion of teaching materials and tools on design for sustainability in an open-source and copy left ethos

This is the post-print version of the Article. The official published version can be obtained from the link below - Copyright @ 2011 InderscienceThis paper presents the intermediate results of the Learning Network on Sustainability (LeNS) project, Asian-European multi-polar network for curricula development on Design for Sustainability. LeNS is a mechanism to develop and diffuse system design for sustainability in design schools with a transcultural perspective. The main output of the project is the Open Learning E-Package (OLEP), an open web-platform that allows a decentralised and collaborative production and fruition of knowledge. Apart from the contents, the same LeNS web-platform is realised in an open-source and copy left ethos, allowing its download and reconfiguration in relation to specific needs, interests and geographical representation

Making Design Rules: A Multi-Domain Perspective

This study analyzes the processes whereby organizations develop radical innovations in response to environmental transformations. It explores the changes in organizational structures, practices and business strategies entailed by the implementation of such innovations. From the literature on modularity, we borrow the idea that the evolutionary dynamics of artifacts and organizations are linked by design rules, i.e. a set of principles that allocate functions to components, identify the operating principle of each component and determine the interfaces among modules. Through an in-depth case study of radical innovation in tire manufacturing, we study the joint dynamics of technical and organizational change during the transition from old to new design rules. We argue that technical change and organization adaptation are linked, but that such relationship is mediated and rendered open-ended by the evolution of the underlying bodies of knowledge.organizational change, innovation, technological change, modularity, tire manufacturing

Parallel Integer Polynomial Multiplication

We propose a new algorithm for multiplying dense polynomials with integer coefficients in a parallel fashion, targeting multi-core processor architectures. Complexity estimates and experimental comparisons demonstrate the advantages of this new approach
