This book was released on 2013 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing costs, consumer awareness, and environmental legislation have driven industry to reduce its resource consumption and the impact from that consumption. So, both traditional economic objectives (e.g., cost, time, and quality) and environmental objectives (e.g., CO2 emissions) have become strategically relevant for the manufacturing sector. For many manufacturing companies, production systems have a major influence on the environmental footprint of a product and therefore represent a major opportunity to minimize the company's overall environmental impact. Currently within industry, there is not an accurate, effective, or widely accepted method to assess the resource consumption of process chains used to manufacture a product. As a result, this information is often not considered when making decisions about what processes to use. A considerable part of the energy and resource demand in manufacturing is determined during production planning. An important component of this planning is determining the process chains to be used. Process chains are a combined sequence of specifically arranged, single processes used to manufacture a product. As manufacturing processes are very resource intensive, it is now necessary to assess the resource consumption as well as the economics of these process chains. Because of this, additional information must be considered when selecting the process chains used to manufacture a product. Many life cycle assessment (LCA) tools focus on the materials and final disposition of a product, but do not include detailed information or data on the manufacturing required to fabricate the product. Sustainability impacts of discrete manufacturing processes and product value streams are needed to develop more complete LCAs. The development of a methodology and user tool to quantify sustainability impacts, leading to the identification of gaps and opportunities, is essential to facilitate decision making to support sustainability in manufacturing facilities. To address these issues, this dissertation proposes an approach to evaluate and quantify the resource use in addition to the environmental and economic impacts associated with discrete manufacturing processes as part of a complex process chain. A methodology to evaluate multiple process chain configurations will be presented. First, a database of industrial assessment metrics was compiled. This database allows users to sort and select from a list of key metrics in order to choose the metrics that are relevant for the performance that they want to measure. Next, an industrial assessment methodology was developed. This methodology gives users an overview of the key areas to address when conducting an industrial assessment. This methodology, which was applied to three case studies, can be used in combination with the key metrics. In the second part of the dissertation, a resource consumption assessment and mapping methodology for complex manufacturing process chains was developed. This systematic methodology was developed to identify and quantify the resource consumption (energy, water, materials) for discrete manufacturing processes. The processes mapped include: welding (manual and robotic), cutting (plasma arc and laser), rework (air carbon arc cutting and hand grinding), and machining (milling). Next, a model consisting of database modules for each process was developed. This model quantifies the sustainability impacts (energy, water, and material consumption, waste generation, emissions, and resource consumption cost) of manufacturing process chains. The model was validated using a case study with Caterpillar Inc. for a process chain including welding, plasma arc cutting, laser cutting, and milling. Next, a process chain assessment tool was created. This tool enables manufacturers to assess the resource consumption and associated impacts of multiple fabrication process chain configurations. This enables a more comprehensive assessment compared to other software tools. Finally, a methodology modeled after the Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) process was presented to show how to translate the results from the model and tool to an Environmental Value Stream Map and to translate those results into improvements in manufacturing systems. This methodology was validated on a machining operation in a Caterpillar facility. This research has developed and evaluated an effective approach for the analysis of energy, water, and other resource use in multiple processes in a manufacturing process chain. This allows manufacturers to better understand the resource consumption and environmental and economic impacts of fabrication process chains used to make a product. This dissertation helps to provide the technical understanding and tools to enable designers and manufacturing engineers to create manufacturing systems that are truly more sustainable. The implementation of this work can be directly applied to assessing and optimizing manufacturing process chains and the work presented in this dissertation directly contributes to the realization of a sustainable and prosperous manufacturing sector.

Available in PDF, EPUB and Kindle. Book excerpt: This timely work examines one core corporate function that has a profound and direct impact on corporate environmental performance – manufacturing and operations. This area has been of concern in recent years to researchers and practitioners in fields ranging from the social and natural sciences to management and technical engineering. The book reflects this diversity with global contributions on topics such as design for the environment, total quality environmental management, green supply chains, reverse logistics, environmental management systems and standards, industrial ecology, closed-loop manufacturing, life-cycle management, pollution prevention (P2), environmental technologies and energy efficiency. The aim and scope of Greener Manufacturing and Operations is to capture state-of-the-art and future practices in environmental manufacturing and operations practices and issues in one concise volume. The book is therefore a fluid mix of case studies, empirical research, and applied theoretical works incorporating both conceptual ideas whose time will come to practical applications which managers and practitioners can apply immediately. Comprehensive in its coverage of the key issues, contributions range from a focus on the internal operations of a single function within an organization to a consideration of industrial manufacturing practices from a macro-economic level. A number of levels of decision-making are also represented: from long-term strategic issues such as supply chain design, to traditional short-term operations decision-making and planning issues such as production planning. Many of the principles developed and presented here can also be extended to the more general process management of service organizations. The book is organized into four major sections: operations strategy and policy; manufacturing and operations practice; tools for managing greener operations and manufacturing; and, finally, case studies. Greener Manufacturing and Operations will be an essential aid for managers, engineers, students, researchers, and consultants wishing to understand the various issues, principles, and tools for managing the operations and manufacturing function in a more environmentally-benign and sustainable manner.

This book was released on 2024-03-21 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Motivation: Throughout the life cycle, the environmental impact and manufacturing costs of a part are largely determined at the design stage. Therefore, a part design optimization method considering these two factors is proposed in this paper. At the same time, the comprehensive benefit is taken as the trade-off of these two factors. The reduction of the comprehensive benefit indicates that the optimized part has achieved better environmental and economic performance results. Methods: Firstly, the model is reconstructed using the dimension-driven method, and the feature information of the new part is extracted. Then, machining process planning is carried out based on the feature information. Secondly, a design optimization model for the comprehensive benefit is established based on the genetic algorithm. The model takes the dimension parameters of the part as the optimization variables and the reduction of the comprehensive benefit as the optimization objective. With the help of the Simulation plug-in for SolidWorks, the static analysis of the optimized model is conducted to determine whether it meets the performance requirements. Finally, the design optimization prototype system oriented to comprehensive benefit is established. The feasibility and effectiveness of the proposed method are verified by taking the intermediate shaft of the belt conveyor reducer-sixth order step shaft as an example. Results: The case study shows that the optimization result of comprehensive benefit is 1.63%, which verifies the feasibility and effectiveness of the part design optimization method proposed in this paper.

This book was released on 2012-01-05 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Design is becoming an increasingly significant agenda for many manufacturing companies and yet there is no standard to their approaches, strategies or their levels of execution. Applying Design for Environment (DfE) methodologies to develop a more sustainable supply chain has formed procedures and techniques which allow designers to integrate these methods with environmental supply chain management. Design for Environment as a Tool for the Development of a Sustainable Supply Chain aims to define relevant target specifications for a product throughout its life cycle; from conception and design to the end of its operating life. Be considering this new approach to the supply chain, environmental responsiveness can work in tandem with sounds business management. The usual focus on suppliers, manufacturers and customers is expanded in Design for Environment as a Tool for the Development of a Sustainable Supply Chain to include stakeholders such as government bodies and recycling companies. The influence of these additional groups is analyzed alongside concepts such as: Product life cycle development aimed at environmental impact minimization; Supplier selection and management based on environmental criteria; and Marketing and communication choices which increase the value of environmentally sensitive products. By including several case studies alongside theoretical topics, Design for Environment as a Tool for the Development of a Sustainable Supply Chains acts as a foundation for professionals across the supply chain, from industrial designers to marketing and sales departments, who are involved in environmental issues.

Download or read book Integrating Sustainable Manufacturing Assessment Into Decision Making for a Production Work Cell written by Hao Zhang and published by . This book was released on 2012 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainability has been the focus of intense discussions over the past two decades, with topics around the entire product life cycle. In the manufacturing phase, research has been focused solely on environmental impact assessment or environmental impact and cost analysis in its assessment of sustainability. However, few efforts have investigated sustainable production decision making, where engineers are required to concurrently consider economic, environmental, and social impacts. An approach is developed to assess broader sustainability impacts by conducting economic assessment, environmental impact assessment, and social impact assessment at the work cell level. The results from the assessments are then integrated into a sustainable manufacturing assessment framework, along with a modified weighting method based on pairwise comparison and an outranking decision making method. The approach is illustrated for a representative machining work cell producing stainless steel knives. Economic, environmental, and social impact results are compared for three production scenarios by applying the sustainable manufacturing assessment framework. Sensitivity analysis is conducted to study the robustness of the results. For future research, it is desired that a tool which integrates manufacturing information system information and the sustainable manufacturing assessment approach can be built to assist production engineers in considering sustainability performance when making decisions.

Download or read book Sustainability Assessment During Early Product Development written by Seyedhamed Seyedmahmoudighomi and published by . This book was released on 2014 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research explored in this thesis helps provide a better understanding of efforts that have been undertaken to more precisely calculate environmental impacts and human health risks, such as energy consumption, carbon footprint, and toxicity, to support environmental sustainability assessment of products. The work is comprised of two research objectives, the first research objective explores the integration of the environmental aspect of sustainability performance into the design of common products, manufacturing processes, and relevant supply chain networks to assist decision makers. The second research objective explores the challenges of safety concerns, human health risks, and toxicological responses in developing novel products. The framework developed for the first objective relies on manufacturing and supply chain unit process modeling, and is demonstrated for the evaluation of backpack design variants. It is shown that simultaneous consideration of manufacturing and supply chain processes can impact decision-making and improve product sustainability from an environmental perspective at the design stage. For the second objective, nanomaterials are a focus due to their potential to enable advanced technologies; however, little is known about their effects on the environment and human health. This research builds on a prior investigation of the stability and toxicity characteristics of zinc oxide nanoparticles (ZnO NPs) used in metalworking nanofluids (MWnF). For stability analysis and toxicological assessment, the dynamic light scattering (DLS) method and the zebrafish assay method are applied, respectively, to evaluate the development of TiO2 and ZnO MWnF formulations. In general, the results reveal addition of these NPs causes a higher mortality rate in comparison to NP-free formulations. From this thesis research, it is concluded that integrating evaluation of sustainable manufacturing and use performance into early product development provides the opportunity for improved engineering decision making. As a contribution, a point of departure is established for the research community to move current efforts forward for concurrent consideration of multiple stages of the product life cycle in pursuit of environmental, economic, and social sustainability. By pursuing this path, future research will ease some of the most challenging recent issues faced by decision makers globally, including use of non-renewable resources, GHG emissions and climate change, human health risks, toxicity, and potential health hazards.

This book was released on 2009-06-13 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Perspective on Two Decades of Rapid Modeling It is an honor for me to be asked to write a foreword to the Proceedings of the 1st Rapid Modeling Conference. In 1987, when I coined the term “Rapid Modeling” to denote queuing modeling of manufacturing systems, I never imagined that two decades later there would be an international conference devoted to this topic! I am delighted to see that there will be around 40 presentations at the conference by leading researchers from aroundthe world, and about half of these presentationsare represented by written papers published in this book. I congratulate the conference organizers and program committee on the success of their efforts to hold the ?rst ever conference on Rapid Modeling. Attendees at this conferencemight?nd it interesting to learn about the history of the term Rapid Modeling in the context it is used here. During the fall of 1986 I was invited to a meeting at the Headquarters of the Society of Manufacturing Engineers (SME) in Dearborn, Michigan. By that time I had successfully demonstrated s- eral industry applications of queuing network models at leading manufacturers in the USA. Although in principle the use of queuing networks to model manufact- ing systems was well known in the OR/MS community and many papers had been published,the actual use of suchmodelsby manufacturingprofessionalswas almost nonexistent.
