Fuzzy Multicriteria ABC Supplier Classification in Global Supply Chain

Abstract

The determination of the optimal purchasing strategy in enterprise that is a part of global supply chain could be performed in two steps. In step one, a classification of potential suppliers is performed in order to determine the optimal portfolio of suppliers. This is delivered by using the fuzzy multicriteria proposed ABC classification method. Uncertainties in relative importance of criteria and their values are described by linguistic expressions. Modelling of linguistic expressions is based on the fuzzy sets theory. In the second step, ranking of optimal portfolio of suppliers is performed by using the modified ELECTRE method. The obtained results represent valuable input for determining the long time purchasing strategy and building partnership with the best suppliers. The developed two-step model is verified on real life data. The obtained results indicate good compliance with the opinions management in this type of industry. It is worth to mention that the proposed model can be easily extended and adopted to the analysis of other issues of management which could be applicable in different research areas.

Sovereign Credit Risk Assessment with Multiple Criteria Using an Outranking Method

“…Doumpos et al [28] draw special attention to areas such as medicine, human resources, marketing, finance, and energy management. Other examples include civil construction [29], evaluating suppliers in supply chains [30], portfolio decision analysis [31], assessing human resource skills management [32], public safety [33], jobsatisfaction [34], location selection [35], and ranking credit risk algorithms. The use of MCDM/A for Risk Management decisions has been increasing lately.…”

ABC Classification of Risk Factors in Production Supply Chains with Uncertain Data

“…Unfortunately, there are only a few papers which consider the problem of RFs classification in the literature. Classifications of other items with respect to many fuzzy criteria are considered in the literature [31,32]. The classification criterion is defined as the product of fuzzy demand frequency and fuzzy costs [31].…”

“…The classification criterion is defined as the product of fuzzy demand frequency and fuzzy costs [31]. Kefer et al [32] have analyzed the problem of the classification of potential suppliers in a complex supply chain with respect to three fuzzy criteria. The classification criterion is defined as Euclidean distance between estimated and maximum values of the considered fuzzy criteria.…”

Proposta de modelo de decisão para avaliação de fornecedores baseado no ELECTRE TRI para categorização e na teoria dos conjuntos <i>fuzzy</i> para a modelagem da incerteza e hesitação de múltiplos tomadores de decisão

“…No que diz respeito à qualificação de fornecedores ou pré-seleção, ainda há poucas pesquisas que abordem técnicas de apoio à tomada de decisão, dentre as quais, pode-se citar Yu e Wong (2015), Yu e Wong (2014), Gu, Gao e Wu (2008), Kefer et al (2016), Lima Júnior, Osiro e Carpinetti (2013b), Sepulveda e Derpich (2015), Wu e Barnes (2012), Hallikas et al (2005), Li e Shang (2009), Irfan, Shengchun e Xiaofei (2011) e Cao et al (2014). É importante destacar que a qualificação requer o uso de um método ou técnica de classificação, não de ordenação, e deveria considerar o uso de regras não compensatórias (DE BOER;LABRO;MORLACCHI, 2001; LIMA JUNIOR; OSIRO; CARPINETTI, 2013a), uma vez que visa garantir níveis mínimos de desempenho em cada critério.…”

“…acordo com Wu e Barnes (2012), a primeira etapa do processo consiste em determinar o conjunto de possíveis parceiros aceitáveis, enquanto as etapas seguintes terão por objetivo a redução do número de fornecedores considerados.Alguns autores argumentam que a qualificação de fornecedores tem o potencial de proporcionar muitos benefícios no processo de seleção(DE BOER;LABRO;MORLACCHI, 2001;KEFER et al, 2016). Isto ocorre, pois, cadeias de suprimentos globais podem apresentar um grande número de potenciais fornecedores e, por este motivo, a definição de um portfólio ideal pode economizar tempo, diminuir os custos, entre outros benefícios(KEFER et al, 2016).Na literatura existem números estudos propõem o uso de diferentes técnicas de apoio à tomada de decisão na seleção de fornecedores, conforme se pode observar nas revisõesde Ho, Xu e Dey (2010), Ware, Singh e Banwet (2012), Setak, Sharifi e Alimohammadian (2012) e Chai, Liu e Ngai (2013). Entretanto, a maioria destes estudos não aborda a qualificação de fornecedores.…”
