The selection of an optimal material is an important aspect of design for mechanical, electrical, thermal, chemical or other application. Many factors (attributes) need to be considered in material selection process, and thus material selection problem is a multi-attribute decision making (MADM) problem. This paper proposes a new MADM method for material selection problem. G1 method does not need to test consistency of the judgment matrix. Thus it is better than AHP. In this paper, firstly, we use the G1 method to determine the attribute weight. Then TOPSIS method is used to calculate the closeness of the candidate materials with respect positive solution. A practical material selection case is used to demonstrate the effectiveness and feasibility of the proposed method.

The need for environmentally compliant processes and materials in the Painting Industry grows more pressing every day. As the need for these processes grows, so grows the confusion regarding the selection and implementation of these new methods and materials. In the past, price and traditional procedure were the only criteria by which a material was procured. Speed and compliance with Original Equipment Manufacturer specification governed how things were done on the shop floor. With the advent of the environmental regulations, processes are being examined all across the globe. In many of the larger companies, the chief environmental officer has as important a role as the comptroller or Chief Financial Officer. Environmental managers are often not chemists or line painters, and typically, the environmental manager is skilled only in the policies of waste disposal, spill clean up, or remediation. The methods whereby a company can minimize the generation of hazardous waste remain less familiar. Often the examination of possible alternate techniques and materials are left for the last minute, or are conducted by personnel who are unfamiliar with how to make changes work. This is usually a recipe for failure in the implementing of anything new. This paper will suggest methods for selection of alternative products and processes in a clear and organized manner. Salient discussion points will be: 1. Process Examination 2. Material Selection 3. Steps For Successful Implementation 4. Possible Impediments 5. How to Avoid Risky Alternatives It will focus on procedures that will assist in the decision making process, and hopefully be of use in the choosing of environmentally sound equipment, chemicals, and methodologies.

This complete guide to the selection of materials for interiors has been updated to reflect the most recent materials on the market and contemporary awareness on industry movements like sustainability. Written from the viewpoint of the working designer, Interior Design Materials and Specifications, 4th Edition, describes each material's characteristics and teaches students how to evaluate, select, and specify materials, taking into account factors including code compliance, building standards, sustainability guidelines, human needs, and bidding processes. Students will learn how to communicate with suppliers and vendors to achieve the results they envision and how to avoid some of the pitfalls common to material selection and specification.

Quotations and references, taken from old texts on stream channel works (today classified as belonging to soil bioengineering interventions), are presented and discussed. Part I of the same study previously showed a similar analysis on slope stabilization [Bresci 2002]. The selected quotations are reported in a chronologic order to highlight the historical evolution in each work description and, in particular, the instructions and adjustments to put on when carried out. Where suggestions for vegetation material selection and numerical indications are found in the analyzed texts, they have been reported translated into English. The selection of the analyzed works has been carried out among those utilized for streambank protection, a sector where more often vegetation is utilized. Also in this case (Part II) it is demonstrated that bioengineering techniques clearly originate from forest watershed management.

Purpose – The purpose of this paper is to propose and evaluate the selection of materials for the selective laser sintering (SLS) process, which is used for low-volume production in the engineering (e.g. light weight machines, architectural modelling, high performance application, manufacturing of fuel cell, etc.), medical and many others (e.g. art and hobbies, etc.) with a keen focus on meeting customer requirements. Design/methodology/approach – The work starts with understanding the optimal process parameters, an appropriate consolidation mechanism to control microstructure, and selection of appropriate materials satisfying the property requirement for specific application area that leads to optimization of materials. Findings – Fabricating the parts using optimal process parameters, appropriate consolidation mechanism and selecting the appropriate material considering the property requirement of applications can improve part characteristics, increase acceptability, sustainability, life cycle and reliability of the SLS-fabricated parts. Originality/value – The newly proposed material selection system based on properties requirement of applications has been proven, especially in cases where non-experts or student need to select SLS process materials according to the property requirement of applications. The selection of materials based on property requirement of application may be used by practitioners from not only the engineering field, medical field and many others like art and hobbies but also academics who wish to select materials of SLS process for different applications.

Based on the material of Russian linguistics, the article proves the thesis about the ethnomenal conditionality of research activity in terms of its various components: by the nature, quality, volume of factual material, selection of methods and ways of research, by observing the principle of consistency and historical and cultural localization of observations and generalizations. Signs of scientific ethno-mentality are identified and considered on the example of research by a number of prominent figures of Russian science.
