Abstract In the development of mechatronic systems, it is important to differentiate products be developed from those competitors, but also own product generations already available on market. However, there are uncertainties regarding correct features differentiated customer and user perspective how these should designed. Nevertheless, despite high impact, decisions must taken early in process...

Electronic B2B marketplaces bring together many online suppliers and buyers, each of which can potentially use his own format to represent the products in his product catalog. The marketplaces have to perform non-trivial mappings of these catalogs. In this paper we analyze the problems which occur during integration, taking several leading XML and non-XML formats as examples. We discuss the met...

Structured methods and formal methods for software development can supplement each other by eliminating each other's weak points. It is even better if an eeciently high level of integration can be achieved such that the products of each method can automatically be transformed into a product of the other method. In this paper a small case study is presented in which this principle is illustrated...

Alternative Legendre polynomials (ALPs) are used to approximate the solution of a class of nonlinear Volterra-Hammerstein integral equations. For this purpose, the operational matrices of integration and the product for ALPs are derived. Then, using the collocation method, the considered problem is reduced into a set of nonlinear algebraic equations. The error analysis of the method is given an...

Gauss-Kronrod product quadrature formulas for the numerical approximation of R 1 ?1 k(x)f (x)dx are shown to converge for every Riemann integrable f , and to possess optimal stability. Similar results are proved for the product formulas based on the Kronrod nodes only. An application to the uniform convergence of approximate solutions of integral equations is given.

In this study we present a novel integration between product portfolio management evaluation criteria and product design decisions involving the design of chemical-based configured consumer products.We consider the variance contributionmade by the product’s quality characteristics to the product’s economic performance that is measured via its net present value (NPV). The sensitivity-based time-...
