Diving into the dynamics of product evolution : analyzing technological discontinuities during the era of incremental change and cognitive convergence on a dominant design

Olivier Waeber

Three distinct stages describe the technological evolution of a product over time: ferment, convergence on a dominant design and an era of incremental change. Until recently, the era of incremental change has been characterized as stable and one that invol ...

On the optimal frequency of multiple generation product introductions

Ralf Seifert, Shuangqing Liao

This paper considers a firm that introduces multiple generations of a product to the market at regular intervals. We assume that the firm has only a single production generation in the market at any time. To maximize the total profit within a given plannin ...

Design of a semantic knowledge base to support the product development process

Paul Xirouchakis, Predrag Spasojevic

New product development today is a knowledge-heavy process, but very often this knowledge is not adequately handled, it’s not made readily available to the actors, or is lost within or between similar projects. Furthermore, different legacy tools and data ...

An empirical study on the characterization of machined surface integrity by chip morphology in dry end-milling of titanium alloy

Muhammad Arif

Titanium alloys manifest low thermal conductivity and high work hardenability in machining. These alloys are thus considered as difficult-to-machine at higher cutting speeds and pose serious problems in machining such as degraded machined surface and rapid ...
