Material selection problem is important for the product design, and contains many influence factors. Thus it is actually a multi-attribute decision making (MADM) problems. The aim of this paper is to propose a new decision method based on the projection method for the material selection problem, in which attribute values expressed with interval numbers. An objective determining weights method is proposed according to coefficient of variation method. A practical example is used to illustrate the effectiveness and practicability of the proposed method.

This paper proposes neutrosophic vague N-soft sets which is composed of neutrosophic vague sets and N-soft sets for the first time. The new hybrid model includes a pair of asymmetric functions: truth-membership and false-membership, and an indeterminacy-membership function. Some useful operations and propositions are given and illustrated by examples. Moreover, a method of priority relation ranking based on neutrosophic vague N-soft sets is presented. The validity of the method is verified by comparison. It is more flexible and reasonable to use this method in our daily life. Finally, a potential application of multi-attribute decision making is presented.

AbstractDecision making in material selection plays important role in selecting appropriate material based on design and manufacturing attributes. Proposing a new material is always a challenging task so the researchers used Decision making assistance tools. In the Present paper the application of Multi-Attribute Decision Making (MADM) methods are applied to the piston material selection for optimal design process. Comparative study of subjective and objective criteria weights on selected MADM methods are done. Sensitivity analysis is conducted to prove the consistency in performance score ranking order as the criteria weights for each alternative varies.

The article deals with a novel hybrid two-step group multi-attribute assessment model of stairs shape for two-story individual dwelling houses. There exist many available shapes of stairs for two-story dwelling houses. Selection among shapes and construction of stairs is a multi-attribute decision making problem in nature. It depends on a lot of different conflicting attributes, that have different optimisation direction, different measurement units. A determinated set of the main attributes to assess the alternatives includes the following: Stairwell Area, The Total Area of Climbing, “Climbing Lane" Area, The Cost of Stairs, and Ergonomics. The values of attributes and importance of attributes are determined by grey numbers. The paper presents a novel original hybrid model, which is based on two different multi-attribute decision making methods: ARAS-G (Additive Ratio Assessment) and AHP (Analytic Hierarchy Process).

The present article provides an operational energy comparison of modern concrete and foamed geopolymers as envelope materials for single unit housing in Ecuador. The study is performed by replacing the concrete material used in the walls and roof elements with foamed geopolymer components. Residential building sector requires around 35.6% of the total energy demand in Ecuador. For this reason, efforts on building practices improvement are relevant for the Ecuadorian society. The foamed geopolymers are a mixture of aluminosilicate material obtained from Ecuadorian natural zeolite, group of alkaline activators and the foamed agent that when mixing the raw materials and obtain the geopolymer. To assess the potential use of foamed geopolymers as construction material, the annual energy demand for a social interest dwelling was obtained through simulation with EnergyPlus. Prefabricated Insulated Concrete Forms was established as the construction practice for the building model. Annual energy simulations were performed considering two Ecuadorian representative weathers, to Guayaquil and Quito locations. Material properties of foamed geopolymers ware acquired by own experimental facilities. Thermal conductivity was obtained with the use of the hot plate method, while specific heat by means of differential scanning calorimetry (DSC) analysis. This analysis uses foamed geopolymers obtained from two procedures. Thus, these proposed materials presented low density, low thermal conductivity, and acceptable compressive strength values. Finally, an assessment of natural geopolymers as a concrete replacement is presented, including a thermal characterization, and a sustainable construction evaluation. The findings affirm the key role of material selection in construction practices. Reductions around 4.0% in annual electricity demand was achieved for Guayaquil case, while energy consumption decreases around 1.3% for Quito.
