    A broad range of assistance systems can be found in manufacturing practice as well as in the corresponding literature. Similarly, it can be observed that there is a growing need for and an increasing supply of assistance systems of all kinds. However, for digital manufacturing, the assistance systems are not clearly characterized. The diversity in application areas and possible uses varies and there are no possibilities for comparison. This paper addresses the topic of assistance systems and examines the various basic elements of engineering activities in terms of possible types of assistance systems based on research in manufacturing industry. Crucial aspects of assistance capabilities for engineering are elaborated and possible digital approaches are validated based on investigations in the field of aircraft engine design and assembly.

    Digital Twins are new solution elements to enable ongoing digital monitoring and active functional improvement of interconnected products, devices and machines. In addition, benefits of horizontal and vertical integration in manufacturing are targeted by the introduction of Digital Twins. Using the test environment of smart factory cells, this paper investigates methodological, technological, operative, and business aspects of developing and operating Digital Twins. The following Digital Twin dimensions are considered in scientific and application oriented analysis: (1) integration breadth, (2) connectivity modes, (3) update frequency, (4) CPS intelligence, (5) simulation capabilities, (6) digital model richness, (7) human interaction, and (8) product lifecycle. From this, design elements for the development of Digital Twins are derived and presented.

    Investigating challenges of a sustainable use of marine mineral resources

    High-tech products as well as renewable energy systems require ever-increasing quantities and more different metals. The extraction of metals and industrial minerals for the production of consumer goods and machines take place almost exclusively on land now. However, the interest in marine mineral resources has been re-inflamed due to the problem of geopolitical availability, such as fragile or failed raw material states and oligopolistic structures among the producers. This article gives a brief outline of the political, social and economic context of this change in interest in marine mineral raw materials extraction.

    Study on sustainability developments in industrial practice

    Traditionally, manufacturing companies focus on the value-adding processes at production sites but during the last decades, life-cycle thinking is emphasized. The principle of Sustainable Development contributes as a significant driver for this way of thinking. It demands manufacturing companies to implement sustainable aspects into their engineering actions. The state of the art shows that theoretical solutions to integrate sustainability into a company exist at all corporate levels (normative, strategic and operational). Against this background, the question arises how companies are actually implementing sustainability. Within this study, the company's internal implementations were examined. Eventually, the need for action is identified and future recommendations are described.

    A large number of methods have been developed in order to systematically consider sustainability as a design criterion in the product development process. However, further support is required to help product development teams to assess the applicability of the existing methods in the specific design contexts. In order to address this problem, the Design Decision Support Assistant (DDSA)-an IT-based assistance system-has been developed to support product development teams in the selection, scheduling, and application of sustainable product design methods in the product development process. The backbone of the assistant is a method repository comprising 29 methods for sustainable product development as well as a method taxonomy to enable the selection and scheduling of suitable methods for achieving sustainability-related design targets. This article introduces the concept of the DDSA, details its practical prototypical implementation, and illustrates its application in a case study.

    A multitude of information is required to address sustainability aspects in product design decisions. However, information required for applying methods in the field of sustainable product development often overlaps. Moreover, specific improvement measures can primarily be identified if method results can be traced back to data origin. This paper presents a concept and implementation of an information platform which is integrated into a PLM system and integrates an ontology based knowledge model and a semantic wiki. The information platform shall avoid double work, improve documentation of information and assist in understanding the data basis of method results. This paper discusses requirements and solution elements and presents findings from applying the methods Lifecycle Design Strategies (LiDS) Wheel and the Product Sustainability Index.

    A satisfactory multiobjective design that incorporates physical performance as well as sustainability is necessary from a global environmental protection perspective. For obtaining sustainable lifecycles, decision making in the early phases of the design process, considering multiple sources of uncertainty, is important. Previously, we proposed a preference set-based design (PSD) by Inoue et al. (2010) [16] method, which enables a flexible and robust design under various sources of uncertainty while capturing the designers preference based on his/her knowledge or experience. The present study focuses on a decision-making support for sustainable product creation in the early phases of the design process considering the various design uncertainties. We investigate different officially accepted sustainability indicators and identify the ones that are related to the product development process by considering the physical performance and sustainability of the products concurrently. Thereafter, the proposed method is applied to a multiobjective design problem. This paper discusses the applicability of PSD as a decision-making support method for sustainable development using the design of an alternator as an example.
