This book presents decision support tools that can be used in the early design stage to analyze the feasibility of a product and its components for remanufacturing. It also covers how to design a product specifically for remanufacturing and offers supporting case studies.This is a comprehensive solutions guide for remanufacturing decision-making. The book illustrates an approach that can be used at the product End-of-Life (EOL) stage to generate optimized recovery plans for the returned products. Opportunities for Industry 4.0 to support remanufacturing along with case studies are included to showcase the decision-making tools.Remanufacturing and Remanufacturability Assessment for the Circular Economy: A Solutions Guide will be of interest to practitioners, business professionals, and researchers that work in the industrial and manufacturing sectors. Those involved with supply chain management and advanced technologies associated with Industry 4.0, sustainability, and integrated techniques of circular supply chains will also find this book very useful.

Some of the factors for the increased use of plastic pipes in water distribution systems are their ease of installation and handling, durability, and good resistance to the chemicals used in water treatment, such as chlorine. In many urban areas, plastic pipes may come into contact with contaminated soils as a result of leaks from underground storage tanks, chemical spills, and improper disposal of used chemicals. These pollutants from leaking storage tanks and contaminated soils can and have posed serious threats to the longevity and structural integrity of plastic pipes and elastomeric gaskets which, in turn, can affect the water quality in the distribution system. Although there are research studies and case studies documenting the permeation of organic compounds through plastic pipes and elastomeric gaskets, there is still a lack of understanding of the performance of PE and PVC pipe materials and elastomeric gaskets in hydrocarbon-contaminated soils commonly encountered under field conditions. The objective of this project was to study the impact of hydrocarbons on polyethylene (PE) and polyvinyl chloride (PVC) pipes and elastomeric gaskets. ?Specific tasks were to (1) survey water utilities to learn about their experiences with plastic pipes and permeation of mains and services, (2) study permeation through PE and PVC pipes exposed to hydrocarbon contamination, (3) develop laboratory tests to predict permeation of pipes and gaskets, and (4) study permeation through pipe gaskets exposed to hydrocarbons. The research team surveyed utilities by mail and telephone to obtain information about their use of plastic pipes and experiences with permeation incidents and successful uses in known hydrocarbon-contaminated areas. Case histories with relevant laboratory data were developed. Permeation of PE and PVC pipes exposed to soil and water contamination was studied in pipe-bottle apparatuses. Novel pipe-drum apparatuses were used to study permeation of gasketed pipe-joints. New laboratory tests were developed to measure and predict permeation through PVC pipe. The moving front test was used in studies that revised and extended the understanding of the theory of permeation in PVC pipes, the thresholds of environmental contamination that might impact engineering decisions, and the impact of combinations of BTEX compounds on PVC pipe. ?

The process of producing components to final net-shapes is fast becoming a desirable goal for metal working industries. This is due to a combination of factors such as the development of new materials and escalating energy costs. Computer Applications in Near Net-Shape Operations addresses the design, analysis and simulation of near net-shape operations using some of the most advanced computer techniques and tools available. Topics covered include: Sheet metal forming operations: progressive stamping, fine blanking, nesting, flat pattering, bending and nibbling; Die design, construction and NC programming of wire EDM; Bulk metal forming processes such as cold upsetting and close-die forging; Injection mould design, analysis and simulation; Computer-aided design of CNC machines for near net-shape operations; Intelligent progressive die design system IPD. This collection of the latest developments from leading experts in the field will be of interest to practising engineers, graduate students and researchers of metal forming, stamping, mould and die design.

With the rapid advances in computing and Internet technologies, an integrated and collaborative environment, which is based on the complementary functions of concurrent engineering and Internet-based collaborative engineering, is imperative for companies to facilitate and expedite the product realization processes. Topics such as concurrent and collaborative engineering, feature-based design and manufacturing, evolutionary computational techniques such as Tabu Search, Simulated Annealing, Genetic Algorithms features, intelligent and computer-aided process planning are important strategies and enabling technologies for developing an integrative environment, facilitating modern product design and development. This book covers the state-of-the-art research and development status of these strategies and technologies. Implementation strategies and case studies are provided with an emphasis on technical details to help readers understand the underlying algorithms and infrastructures.
