Complex systems design and especially automotive design is facing continuous technological evolution that needs stronger integration. In this paper, a method for representing system architecture is presented. This method is based on dependencies and constraints propagation which allows us to focus on the co-evolution of product, organization and processes domains. KEY-WORDS: product architectur...

We consider a Fredholm integral equation of the second kind in L1([a, b],C), with a weakly singular kernel. Sufficient conditions are given for the existence and uniqueness of the solution. We adapt the product integration method proposed in C0([a, b],C) to apply it in L1([a, b],C), and discretize the equation. To improve the accuracy of the approximate solution, we use different iterative refi...

Complex products and large engineering systems require massive efforts to integrate designs at various levels: product and production plans into components, components into sub-systems, sub-systems into systems, and systems into a quality product. We define the product development integration problem as the challenge to coordinate the engineering activities at each level in order to achieve an ...

New product development (NPD) is described in the literature as the transformation of a market opportunity into a product available for sale. In the automotive industry, within the context of ISO/TS16949:2002 (the automotive quality management system international standard),  these related to the product realization process (PRP) which consists of Three main phases such as planning, Implem...

This article reviews a method for generating a product model from user data and introduces 12 design patterns for resolving conflicts that may occur in the integration and normalization process. The generating method and design patterns were evaluated during a project to integrate the product models collected from three different precast concrete companies in the United States, testing the new ...

Newton’s method is one of the most famous numerical methods. Its origins, as the name suggests, lies in part with Newton, but the form familiar to us today is due to Simpson of “Simpson’s Rule” fame. Originally proposed to find the roots of polynomials it was Simpson who proposed using it for general nonlinear equations and for its use in optimization by finding a root of the gradient. Here we ...
