Selection Of

Two analytical approaches are described for computer-aided selection of engineering materials. With given design or selection properties in mind, various materials within a given class may be rated by means of minimization procedures in conjunction with assignable engineering judgment factors. The first approach uses a geometric analogy in which two encompassing material parameters—“mean weighted characteristic” and “balance factor”—are used as a measure of the closeness of fit to a shape defined by desired material properties. The second approach is a variation on a familiar algebraic aid to decision making. In the latter approach materials are selected with the least total sum of property deviations from those desired. A number of examples dealing with plastics are given. Comparisons are made between the two approaches. Both approaches offer advantages over “hit and miss” procedures. By segmenting material classes and by limiting the number of material properties, an iterative and useful program has been proven on a minicomputer.

A methodology developed specifically for the evaluation of requirements of materials intended to high-demanding applications is the stringency levels methodology. The objective of this work is to perform a sensitivity analysis of the methodology of multicriteria stringency levels for the evaluation of technological requirements of materials, creating a new methodology that provides a final results studying variability that let us make an objective decision. The case study has been the evaluation of steels used in the manufacture of components housed in the primary loop of a nuclear power plant. To ease the calculation of the stringency levels, the algorithm has been computed in Labview®. Considering the dispersion that can generate the numerical weighting process, the analysis has shown that the variability in calculated values is not significant. The analysis proposed with this methodology could be used, in the future, for the selection of materials for innovative manufacturing processes.

Distance evaluation and its improved algorithms using Vertical distance instead of Euclidean distance were discussed in engineering materials selection. Taking the selection of materials for low temperature storage container as an example, based on eight kinds of evaluation indices, according to the weight obtained by AHP method, ten kinds of candidate materials were evaluated by using distance evaluation and its improved algorithms. The results indicate that, the optimal material selected coincides with the practice of industry, and the sequence of the candidate materials arranged using improved algorithms is more reliable, which shows that improved algorithms of distance evaluation is a feasible and effective way for engineering materials selection.

The significant part of the constructions’ value consists of construction materials price. With the aim of using financial resources for the construction effectively, it is very important that well considered and reasonable decisions should be made regarding the selection of construction materials. Most of all construction on‐line systems seek to find how to make the most economic construction decisions and essentially these decisions are intended only for economic objectives. Construction alternatives that are under evaluation have to be evaluated not only from the economic position, but also take into consideration qualitative, technical, technological and other characteristics. Additionally, in seeking to facilitate the work of decision‐makers, computer technologies are used that operates according to particular models. These models are based on special mathematical methods in order to facilitate decision‐making and apply to a certain decision area. In this article, the possibilities of applying methods for popular decision‐making are analyzed regarding the selection of construction materials.

It is well known fact that materials play an important role in engineering design. Nowadays over a hundred thousand available materials can be distinguished with constant tendency for increasing the novel designed materials. Therefore material selection process becomes a complex and time consuming task. Selection of the most suitable material for a given application can be regarded as a multi-criteria decision making (MCDM) problem with conflicting and diverse objectives. New MCDM methods have been developed, and existing methods improved, showing that research in the decision-making is important and still valuable. This paper describes the use of recently developed MCDM methods, i.e. Complex Proportional Assessment (COPRAS) and Weighted Aggregated Sum Product Assessment (WASPAS) for selecting the most suitable hard coating material.
