Abstract:To be able to compete in the domestic plastic industry, small and medium-sized enterprises producing plastic need to proactively find the supply of raw materials, avoiding shortages like in the previous years. Purchasing is extremely important and will create a competitive advantage with competitors in the market, so finding suppliers will determine the success in the later stages of the production chain. With the development of the current information system, selection and evaluation have become important in … Show more
“…As far as we know, none of the outranking methods available in the literature integrate ELECTRE and VIKOR under uncertainty and dynamic perspectives. The advantages of this integration have been previously discussed [34], [44], [45]. Some of them are accurately proposing a compromise solution, identifying the best alternative, providing a complete ranking of alternatives, offering different ranking orders based on different DM strategies, describing uncertainty, and incorporating it into the problem.…”

“…Considering that this method is conceived to tackle real-world scenarios, it is designed to be easy to understand and easy to replicate. This design sets it apart from other available methods [22], [34], [44], [45], [60]. Although an application for a renewable energy indicator ranking was provided, future work will seek to apply it to investigate problems in areas such finance, artificial intelligence, and the spread of infections.…”

“…However, VIKOR has limitations when dealing with real-world circumstances. For instance, the values of alternative performance related to a group of criteria should be defined as fixed numbers, which is also an important limitation when attempting to accurately describe complex problems [44].…”

Exhaustive literature reviews of fuzzy sets, theory, and methods are available in [34], [44], [45]. As far as we know, an integration of ELECTRE I and VIKOR under a dynamic IFS perspective does not exist in the literature yet.…”
This paper proposes a methodology for tackling intuitionistic fuzzy-dynamic multi-attribute group decision-making (IF-DMAGDM) problems in the presence of uncertainty. The ELECTRE I approach is integrated with the VIKOR method by considering intuitionistic fuzzy set environments (IFSs). This work introduces a novel form of representing how informed judgements affect the performance of alternatives with respect to attributes at different times that take the form of IFSs. The proposal incorporates three different relative weights: the first is for the decision makers, the second is for the attributes in each range of time, and the last is for the time intervals themselves. The method is suitable for complex and conflicting scenarios, and how an expert's opinion changes over an interval of time is accurately described. An evaluation of the sustainability indicators for renewable energy systems is provided as an illustrative example. To validate the results, a sensitivity analysis and comparative analysis with existing methods are presented.

“…Some other studies are those of Cuka and Kim [8] that developed a fuzzy inference system for tool condition monitoring in end-milling operations and Joshi et al [9] who analyzed surface roughness and material removal rate (MRR) of Inconel 800HT, when machined with copper electrode on electrical discharge machining (EDM). On the other hand, Wang et al [10] employed a fuzzy multicriteria decision-making model (MCDM) for raw material supplier selection in the plastic industry. Likewise, Lin et al [11] applied fuzzy collaborative intelligence approach for fall detection in four existing smart technology applications and a methodology for obtaining technological mean roughness (Ra) for the EDM process, Alarifi et al [42] employed genetic algorithms and particle swarm optimization to determine the parameters of an ANFIS model to predict the thermo-physical properties of Al 2 O 3 -MWCNT/thermal oil hybrid nanofluid and an analysis of the PSO implementation in designing parameters of manufacturing processes as well as a benchmark with other optimization techniques can be found in the review study of Sibalija [43].…”
In Manufacturing Engineering there is a need to be able to model the behavior of technological variables versus input parameters in order to predict their behavior in advance, so that it is possible to determine the levels of variation that lead to optimal values of the response variables to be obtained. In recent years, it has been a common practice to rely on regression techniques to carry out the above-mentioned task. However, such models are sometimes not accurate enough to predict the behavior of these response variables, especially when they have significant non-linearities. In this present study a comparative analysis between the precision of different techniques based on conventional regression and soft computing is initially carried out. Specifically, regression techniques, based on the response surface model, as well as the use of artificial neural networks and fuzzy inference systems along with adaptive neuro-fuzzy inference systems will be employed to predict the behavior of the aforementioned technological variables. It will be shown that when there are difficulties in predicting the response parameters by using regression models, soft computing models are highly effective, being much more efficient than conventional regression models. In addition, a new method is proposed in this study that consists of using an iterative process to obtain a fuzzy inference system from a design of experiments and then using an adaptive neuro-fuzzy inference system for tuning the constants of the membership functions. As will be shown, with this method it is possible to obtain improved results in the validation metrics. The means of selecting the membership functions to develop this model from the design of experiments is discussed in this present study in order to obtain an initial solution, which will be then tuned by using an adaptive neuro-fuzzy inference system, to predict the behavior of the response variables. Moreover, the obtained results will also be compared.
