DFA är en metod som handlar om att designa en produkt så att dess egenskaper kommer att ha en inverkan på monteringsvänligheten av produkten. Det främsta målet med DFA är att reducera antalet ingående detaljer i en produkt. Atlas Copco Tools är ett företag som har påbörjat sin resa mot ständiga förbättringar och fokuserat sig bland annat på att förbättra produktutvecklingsprocessen. Därav har företaget visat ett stort intresse för DFA-metoden som ett arbetssätt inom konstruktionsavdelningen. Idag använder sig inte Atlas Copco Tools av en specifik metod som stödjer DFA-metodiken vid utveckling av deras produkter. Den stora frågan i detta examensarbete är därför huruvida DFA lönar sig att implementeras på Atlas Copco Tools i deras produktutecklingsprocess och i så fall hur arbetet med DFA ska ske samt vilka tillvägagångssätt ska användas. -
Target Value Design Inspired Practices to Deliver Sustainable Buildings
buildings Article Target Value Design Inspired Practices to Deliver Sustainable Buildings Samia S. Silveira and Thais da C. L. Alves * Department of Civil, Construction and Environmental Engineering, San Diego State University, San Diego, CA 92103, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-619-594-8289 Received: 15 June 2018; Accepted: 16 August 2018; Published: 23 August 2018 Abstract: The design of environmentally-friendly buildings relies on the work of interdisciplinary teams who have to look at problems in a holistic way. Teams need to communicate, collaborate, and make decisions not solely based on first cost considerations. For this purpose, Target Value Design (TVD) related practices are being used to deliver green buildings in Southern California while meeting strict code requirements and addressing the needs of multiple stakeholders in a collaborative fashion. This study did not quantify costs associated with design and construction of sustainable buildings. It used an analytical process that compared and contrasted available literature on TVD and interviews with industry practitioners to investigate the use of TVD-inspired practices in the construction industry in Southern California and identify the current use of TVD-inspired practices in the design of green buildings. The study revealed that, even though practitioners might not be aware of how TVD can be fully implemented in these projects, a number of TVD-inspired practices are currently being used. Examples are provided to illustrate their practical use in the design of sustainable buildings and how practice compares to theory regarding TVD implementation.

DEGREE PROJECT IN MECHANICAL ENGINEERING, SECOND CYCLE, 30 CREDITS STOCKHOLM, SWEDEN 2018 Implementing Design For Automatic Assembly A recommendation on how to implement and apply DFAA at Company Y FILIPPA VON YXKULL KTH ROYAL INSTITUTE OF TECHNOLOGY SCHOOL OF INDUSTRIAL ENGINEERING AND MANAGEMENT Implementing Design For Automatic Assembly A recommendation on how to implement and apply DFAA at Company Y Filippa von Yxkull Master of Science Thesis TPRMM: 2018: KTH Production Engineering and Management Industrial Production SE-100 44 STOCKHOLM Abstract The need to work with Design for Automatic Assembly (DFAA) has been widely recognized in the literature. However, the implementation of DFAA is not clearly defined. Therefore, the purpose of this master thesis is to investigate and contribute with knowledge of how DFAA should be implemented into an organization, such as Company Y. Several interviews have been conducted to establish a current state analysis, to receive an understanding of the current problems at Company Y and how to address them. A benchmarking study was conducted, where the three companies Ericsson, Company X and Scania were interviewed. All three companies have successfully implemented DFA and were interviewed with the purpose to obtaining their best practices. The study also included an early implementation of DFAA, where a software based DFA2-method created by Eskilander (2001) was tested on a current product and a new developed design concept at Company Y. Based on this a recommended workflow of the evaluation could be attained. Based on the empirical gatherings several recommendations of how DFAA should be implemented into the organization could be made. -
Design for Sustainability: Overvie and Trends
INTERNATIONAL CONFERENCE ON ENGINEERING DESIGN, ICED'09 24 - 27 AUGUST 2009, STANFORD UNIVERSITY, STANFORD, CA, USA Gaurav Ameta Washington State University, Pullman, WA, 99164-2920, USA. ABSTRACT This paper presents recent trends in Design for Sustainability (DfS) with foresight and strategy as the point of view. We first provide a definition of design for sustainability based on the notion of sustainability. Then, we show the scope of various Design for X concepts in relation to the stages of product lifecycle and the triple bottom lines of sustainability; economy, environment and society. A survey of the recent studies for designing sustainable products is presented followed by the detail summary of various metrics that are used in relation to sustainability and designing environmentally friendly products. Keywords: Design for Sustainability, Sustainability, DfX To understand the meaning of Design for Sustainability, we need to understand the meaning of the word sustainability or sustainable. The word “sustainable” was first used with respect to its current usage as sustainable development. Sustainable development is the development that “meets the needs of the present without compromising the ability of future generations to meet their own needs.” [1]. A definition of sustainability according to the US National Research Council is “the level of human consumption and activity, which can continue into the foreseeable future, so that the systems that provides goods and services to the humans, persists indefinitely” [2]. Other authors (e.g., Stavins et al. [3]) have argued that any definition of sustainability should include dynamic efficiency, should consist of total welfare (accounting for intergenerational equity) and should represent consumption of market and non-market goods and services. -
A Cost-Effective Knowledge-Based Reasoning System for Design for Automation
1 A cost-effective knowledge-based reasoning system for design for automation E M Shehab1* and H S Abdalla2 1Department of Manufacturing, Cranfield University, Cranfield, UK 2Department of Product and Spatial Design, De Montfort University, Leicester, UK The manuscript was received on 3 February 2005 and was accepted after revision for publication on 16 December 2005. DOI: 10.1243/095440554JEM298 Abstract: Design for assembly automation (DFAA) is an important part of the concurrent engineering strategy for reduction of product manufacturing costs and lead times. An intelligent knowledge-based system (KBS) for design for automation and early cost modelling within a concurrent engineering environment has been developed. This paper focuses upon the development of the design for an assembly automation system. The system framework encompasses an extensive knowledge base reasoning system, a CAD system, a design analysis for automation module, a design improvement suggestion module, and a user interface. The development process of the system involved three main stages: creating the KBS, developing the design improvement module, and integrating the KBS with the CAD system. The developed system has the capability to: (a) select the most economic assembly technique for the product at an early design stage; (b) estimate the assembly time and cost for manual, automatic, and robotic assembly methods; and (c) analyse the product design for automation and provide the designers with design improvement suggestions of a product to simplify assembly operations without any compromise of the product functionality. The above capabilities of the system have been demonstrated and validated through a real case study. Keywords: design for automation, concurrent engineering, knowledge-based systems, assembly cost estimation 1 INTRODUCTION good design from the assembly point of view [7]. -

ASSEMBLY SIMULATION THROUGH A DIGITAL MOCK-UP APPLICATION Giampaolo Pascali, Angelo Corallo, Mariangela Lazoi and Alessandro Margherita EuroMediterranean Incubator, University of Salento, Via Monteroni s.n., Lecce, Italy Keywords: Design for assembly, Digital mock-up, Naval sector. Abstract: “Design for X” includes a set of techniques to realize the best product yet during the design avoiding re- works and loose of time and money. Among these, the design for assembly covers an important role and aims to design a product “thinking” to the physical assembling moment. Digital Mock-Up (DMU) is a process to enhance assembly feasibility and efficiency through specific design analysis and allow re- producing a product virtual assembling. Based on an action research based on a collaboration among company and university researchers, the paper aims to describe the development of a DMU application in a naval Italian aerospace company to improve a ship fuel system assembling. Technical features of the application are described. 1 INTRODUCTION company processes, the activities for assembling individual parts to obtain the final product are Different authors face the topics of the new product crucial as they use over 50% of total production development phases (Clark, Wheelright, 1995; time, with costs varying from 20% to 40% for a Crawford, Di Benedetto, 2003; Ulrich, Eppinger, single unit.

Genetic Algorithm Optimization of Product Design for Environmental Impact Reduction
GENETIC ALGORITHM OPTIMIZATION OF PRODUCT DESIGN FOR ENVIRONMENTAL IMPACT REDUCTION JULIROSE GONZALES THESIS SUBMITTED IN FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY FACULTY OF ENGINEERING UNIVERSITY OF MALAYA KUALA LUMPUR 2018 ABSTRACT The growing environmental awareness of today’s consumers has put the manufacturing companies with the burden of taking responsibility for their own product’s environmental impact. This incited the need to develop product management systems which focus on minimizing a product’s impact across its life cycle. However, a survey conducted on Malaysian design companies suggests that there are no systems available for them to include environmental considerations in their product design processes. This dissertation presents a study on product design optimization which focuses on the inclusion of the potential environmental impact in the design consideration. The aim of this research is to develop a methodology that will aid designers to reduce the potential environmental impact of a product’s design, which does not require them to train additional skills in environmental impact analysis. Analysis of the effect of changing the product design parameters such as its dimensions, and basic features on the environmental impact of machining process in terms of its power consumption, waste produced and the chemicals and other consumables used up during the process is the key method in this research. A novel feature-based product design methodology based on an integrated CAD-LCA approach is developed which analyzes a product design’s environmental impact. Genetic Algorithm is applied to the product design parameters to create a feedback system in order to get the best possible product design solutions with the least environmental impact within the product design functionality limitation. -

(2020). Design for Manufacture and Assembly (DfMA) in construction: The old and the new. Architectural Engineering and Design Management, in press. Doi: 10.1080/17452007.2020.1768505 This document is available for personal and non-commercial use only, as permitted by Taylor & Francis Group’s Architectural Engineering and Design Management. The final version is available online: http://www.tandfonline.com/10.1080/17452007.2020.1768505 5 6 Abstract 7 Design for manufacture and assembly (DfMA) has become a buzzword amid the global 8 resurgence of prefabrication and construction industrialization. Some argued that DfMA is 9 hardly new, as there are concepts such as buildability, lean construction, value management, 10 and integrated project delivery in place already. Others believe that DfMA is a new direction 11 to future construction. This paper aims to review the development of DfMA in manufacturing 12 and its status quo in construction, and clarify its similarities and differences to other concepts. 13 A multi-step research method is adopted in this study: First, an analytical framework is 14 generated; Secondly, a literature review is conducted on DfMA in general, and DfMA-like 15 concepts in the AEC industry; The third step is to compare DfMA with related concepts. This 16 study reveals that DfMA as a philosophy is hardly new in construction, and the empirical 17 implementation of many DfMA guidelines has begun in the AEC industry.
