Action Regulation Theory is not only a description tool but also a normative guide to efficient and humanized work; it became a foundation of international standards in work design. The regular mode of action regulation is knowledgebased regulation. Innovation in mental work, e.g., product development, follows a hydrid model of action regulation combining knowledge-driven opportunistic sequence...

Every now and then existing methods in the User-Centered Design (UCD) process evolve and new methods are being introduced. In this position paper we discuss our new approach for studying communities within the new media landscape. First, this new approach contains ways to improve the relations between the designers, researchers and developers on the one hand and the users on the other hand. Sec...

The design of commercial products that are intended to serve millions of people has been a challenge for collaborative approaches. The creation and use of fictional users, concrete representations referred to as ‘personas’, is a relatively new interaction design technique. It is not without problems and can be used inappropriately, but based on experience and analysis it has extraordinary poten...

Despite the many existing Eco-design methods and tools, their use is still limited. When they are used, these methods and tools are often not integrated in the product development process. The purpose of this research is, given a special focus on Eco-design methods and tools, to increase the knowledge concerning engineering designers’ use of methods and tools. Even though more and more approach...

Logistic regression analysis is used to model categorical dependent variable. It is usually used in social sciences and clinical research. Human thoughts and disease diagnosis in clinical research contain vagueness. This situation leads researchers to combine fuzzy set and statistical theories. Fuzzy logistic regression analysis is one of the outcomes of this combination and it is used in situa...

In this paper a novel technique is presented to solve tolerance design problems. To achieve the desired performance tolerance the technique uses a subtle, but significant, change in the design rather than increasing component precision. This change is the addition of a tuning parameter. Statistical models are used to developed framework for the tuning parameter design method. Also developed is ...
