This book was released on 1994 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "This paper concentrates on two types of material- related reasoning that occurs in engineering design: selection and substitution. Selection is based on criteria set out by the designer and is often associated with the process of designing new artifacts from scratch. Substitution, on the other hand, is done when new designs are created by adapting and re-using parts of previous designs. This involves re-evaluating the reasons for a particular material that was used in the base design, and determining whether the same, or new criteria are relevant in the target design. Once the new criteria are established, appropriate materials are selected and substituted. The substitution step, hence, subsumes the selection task. We present a material selection/substitution system that is used as part of a larger case-based design environment. The material selection system helps the designer adapt a previous designs [sic] by suggesting material substitutions that better suit the target application. The system is intended to provide support, right from the conceptual to the detailed stages of design, and can reason about material properties expressed in both numerical and qualitative terms. The system relies on the material selection charts developed by Prof. Ashby of Cambridge University. To enable qualitative reasoning about the charts, we have developed an encoding based on fuzzy set theory. This allows access of materials using specifications expressed in terms of fuzzy orders of magnitude."

Download or read book Decision Making in Manufacturing Environment Using Graph Theory and Fuzzy Multiple Attribute Decision Making Methods written by R. Venkata Rao and published by Springer Science & Business Media. This book was released on 2012-08-27 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decision Making in Manufacturing Environment Using Graph Theory and Fuzzy Multiple Attribute Decision Making Methods presents the concepts and details of applications of MADM methods. A range of methods are covered including Analytic Hierarchy Process (AHP), Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), VIšekriterijumsko KOmpromisno Rangiranje (VIKOR), Data Envelopment Analysis (DEA), Preference Ranking METHod for Enrichment Evaluations (PROMETHEE), ELimination Et Choix Traduisant la Realité (ELECTRE), COmplex PRoportional ASsessment (COPRAS), Grey Relational Analysis (GRA), UTility Additive (UTA), and Ordered Weighted Averaging (OWA). The existing MADM methods are improved upon and three novel multiple attribute decision making methods for solving the decision making problems of the manufacturing environment are proposed. The concept of integrated weights is introduced in the proposed subjective and objective integrated weights (SOIW) method and the weighted Euclidean distance based approach (WEDBA) to consider both the decision maker’s subjective preferences as well as the distribution of the attributes data of the decision matrix. These methods, which use fuzzy logic to convert the qualitative attributes into the quantitative attributes, are supported by various real-world application examples. Also, computer codes for AHP, TOPSIS, DEA, PROMETHEE, ELECTRE, COPRAS, and SOIW methods are included. This comprehensive coverage makes Decision Making in Manufacturing Environment Using Graph Theory and Fuzzy Multiple Attribute Decision Making Methods a key reference for the designers, manufacturing engineers, practitioners, managers, institutes involved in both design and manufacturing related projects. It is also an ideal study resource for applied research workers, academicians, and students in mechanical and industrial engineering.

Download or read book Fuzzy Theory Systems written by Cornelius T. Leondes and published by . This book was released on 1999 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applications of fuzzy theory (often referred to as "fuzzy logic") are maturing and multiplying at a phenomenal rate, and a comprehensive treatment of these real-world techniques and applications is now very timely. Unlike traditional computer logic involving clear true or false decisions, a fuzzy logic system chooses what is most true after "considering" several contributing and possibly conflicting variables. Examples of practical devices using fuzzy computer decision-making are thermostats that respond to a combination of temperature and humidity (comfort factors), an elevator that considers how crowded a car is rather than just its proximity to the desired floor, and a camera that integrates the variables affecting picture quality. These volumes will present a logical progression from implementation and modeling techniques to industrial/commercial applications to fuzzy neural and adaptive fuzzy systems.

Download or read book Materials and Process Selection for Engineering Design Third Edition written by Mahmoud M. Farag and published by CRC Press. This book was released on 2013-11-19 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introducing a new engineering product or changing an existing model involves making designs, reaching economic decisions, selecting materials, choosing manufacturing processes, and assessing its environmental impact. These activities are interdependent and should not be performed in isolation from each other. This is because the materials and processes used in making the product can have a large influence on its design, cost, and performance in service. Since the publication of the second edition of this book, changes have occurred in the fields of materials and manufacturing. Industries now place more emphasis on manufacturing products and goods locally, rather than outsourcing. Nanostructured and smart materials appear more frequently in products, composites are used in designing essential parts of civilian airliners, and biodegradable materials are increasingly used instead of traditional plastics. More emphasis is now placed on how products affect the environment, and society is willing to accept more expensive but eco-friendly goods. In addition, there has been a change in the emphasis and the way the subjects of materials and manufacturing are taught within a variety of curricula and courses in higher education. This third edition of the bestselling Materials and Process Selection for Engineering Design has been comprehensively revised and reorganized to reflect these changes. In addition, the presentation has been enhanced and the book includes more real-world case studies.

Download or read book Innovative Materials for Construction written by Mariaenrica Frigione and published by MDPI. This book was released on 2021-05-05 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the typical materials employed in today’s constructions present limitations, especially concerning their durability, in either common or severe environmental conditions, and their impact on the environment. In response to these issues, academic and industrial efforts around the world have been devoted to developing new smart materials that can provide efficient alternatives, improve the energy efficiency of buildings, or can upgrade, repair, or protect existing infrastructures. Different and wide technological innovations are, therefore, quickly fostering advancements in the field of construction materials. A new generation of materials (bricks, cement, coatings, concrete, FRP, glass, masonry, mortars, nano-materials, PCM, polymers, steel, wood, etc.) is gaining a prominent position in modern building technology, since they can overcome various limits and flaws of conventional materials employed in constructions, without neglecting the smart applications of pioneering materials in ancient constructions and historic buildings. Even though the adoption of innovative materials in the construction field has been a successful route in achieving enhanced performance, or even new and unexpected characteristics, some issues have not been completely solved. On top of them, the cost/performance ratio of novel solutions, since their introduction must be convenient, without compromising quality. Other concerns are related to their sustainability, with eco-friendly options, possibly exploiting recycled materials or by-products from other productions, being the most desirable solution. Finally, the use of materials or systems that are unconventional in this field raises the need to update or develop new specifications and standards. This special issue aims at providing a platform for discussing open issues, challenges, and achievements related to innovative materials proposed for the construction industry.
