Generating design alternatives for increasing recyclability of products

This paper proposes a design support method for improving the recyclability of electronic and electrical products. The method estimates the recycling rate of a product based on its end-of-life scenario. The method supports a designer in generating design alternatives that increase the rate by conducting impact analysis with the change of material composition and end-of-life scenario. The method suggests design alternatives with the constraint of keeping the other performance factors (e.g., flexural strength and thermal conductivity) constant by adjusting the geometric parameters (e.g., thickness and volume) of the components.

Mapping Knowledge about Product Lifecycle Engineering for Ontology Construction via Object-Process Methodology

Knowledge mapping is a first and mandatory step in ontology definition. This paper considers the lifecycle of products and systems, and discusses the creation of a knowledge-based ontology. With respect to the life cycle of products and systems, knowledge refers to the processes involved in their creation (design manufacturing and assembly), use and maintenance, and end of life (EOL). Hence, this knowledge should consider what a product is comprised of (its structure), how it operates (its dynamics), and how it interacts with the environment. A clearly defined and consistent mapping of knowledge regarding structure, operation and interaction is necessary to construct an effective and useful ontology. Yet, in order to obtain the required knowledge and to organize it in a consistent and useful form, an appropriate ontology must be used. An interactive, iterative and consistent method is needed to cope with this complex and circular problem. In this paper, the Object-Process Methodology (OPM) approach is considered, along with OPCAT [1], a tool for OPM-based knowledge modeling. OPM is a systems-modeling approach that represents knowledge about systems concurrently and bi-modally through graphics (a set of Object-Process Diagrams, OPDs) and text (Object-Process Language, OPL, a subset of English), yielding a single, unified and consistent view. In this paper we propose a foundational modeling and ontology construction approach for a generic product that incorporates hardware and software components. The ontology can serve as a basis for a knowledge model to cover the entire product lifecycle, from inception to EOL, and can be applied in the VRL-KCiP Network of Excellence.     

An energy factor based systematic approach to energy-saving product design

In order to reach to an energy-saving product design, this paper presents a mathematic energy model to calculate the total energy consumption within entire product lifecycle. Energy factor is the essential coefficient of this model to represent the energy consumption throughout the entire product lifecycle, including raw material extraction, manufacturing, assembly, use, disassembly, and recycling. With an aim to create a systematic approach to energy-saving product design, the authors integrate the axiomatic design and modularity design theories with energy factor, and the energy factor is eventually optimized together with other major design factors in a multiple objective decision making model.     

Industrial Product-Service Systems—IPS

In mechanical engineering and plant design, product-related services are usually considered as an add-on to the actual product. Industrial Product-Service Systems deal with dynamic interdependencies of products and services in production. Research areas cover new concepts and methods which enable the machine producers to design the potential services in an optimal way, already during the development of the machine. This paradigm shift from the separated consideration of products and services to a new product understanding consisting of integrated products and services creates innovation potential to increase the sustainable competitiveness of mechanical engineering and plant design. The latter allows business models which do not focus on the machine sales but on the use for the customer e.g. in form of continuously available machines. The business model determines the complexity of delivery processes. Characteristics of Industrial Product-Service Systems allow covering all market demands.
