“…Furthermore, the presented MADM model can overcome the flaw of using the single aggregation operator (either the OZNWAM operator or OZNWGM operator) and make up for the prejudices of both. Generally, the superiority of this study is that the presented MADM model not only strengthens the reliability level of OFVs but also makes the decision results more reliable and flexible than existing methods [3,4,24,25,28].…”

“…en, other researchers also introduced a hybrid method of PFSs for MADM [24] and a digraph and matrix approach for risk evaluations [25]. As the generalization of PFSs, the notion of generalized OFVs [26][27][28] was introduced to flexibly present the hybrid information range of the truth-and falsehood-membership degrees regarding different values of the parameter q. en, some aggregation operators of q-rung orthopair fuzzy sets/ values (q-ROFSs/q-ROFVs) [29][30][31] were presented and applied in MADM.…”

The Z number defined by Zadeh can depict the fuzzy restriction/value and reliability measure by an ordered pair of fuzzy values to strengthen the reliability of the fuzzy restriction/value. However, there exist truth and falsehood Z-numbers in real life. Thus, the Z number cannot reflect both. To indicate both, this study presents an orthopair Z-number (OZN) set to depict truth and falsehood values (intuitionistic fuzzy values) and their reliability levels in uncertain and incomplete cases. Next, we define the operations, score and accuracy functions, and sorting rules of OZNs. Further, the OZN weighted arithmetic mean (OZNWAM) and OZN weighted geometric mean (OZNWGM) operators are proposed based on the operations of OZNs. According to the weighted mean operation of the OZNWAM and OZNWGM operators, a multiattribute decision-making (MADM) model is established in the case of OZNs. Lastly, a numerical example is presented to reflect the flexibility and rationality of the presented MADM model. Comparative analysis indicates that the presented MADM model can indicate its superiority in the reliability and flexibility of decision results. Meanwhile, the resulting advantage of this study is that the presented MADM model can strengthen the reliability level of orthopair fuzzy values and make the decision results more reliable and flexible.

“…In the first step, the digraph is used to reveal the relationships of multiple factors in relation to each other (Virmani et al 2021 ). A digraph that visually presents the system is advantageous for presenting the model and relationships (Luqman et al 2021 ). In the second step, the matrix representation is developed to analyse the graphic representation (Mangla et al 2019 ).…”

Investigating the role of stakeholder engagement for more resilient vaccine supply chains during COVID-19

The complexity of the supply chains and the uncertainties in the processes cause business to become more vulnerable in the face of disruptions. Pandemic situations such as COVID-19 cause sudden disruptions in supply chains, causing processes to be disrupted. Especially in multi-stakeholder supply chains, the importance of stakeholder communication, motivation, and regulations i.e. comes to the forefront in order to ensure the resilience of supply chains. As learned with the COVID-19 pandemic, vaccine supply chains are also one of the multi-stakeholder supply chains and are extremely vulnerable to disruptions. In COVID-19 times, the importance of vaccine supply chain management and the resilience in vaccine supply chains increased. To have more resilient vaccine supply chains, stakeholder engagement is an essential issue. Therefore, the Graph Theory Matrix Approach has been used to determine factors of stakeholder engagement in multi-stakeholder vaccine supply chains and to specify the relationships between the factors of project and stakeholder engagement in vaccine supply chains to increase resilience in disruption times. The aim of the study is to identify the factors of project and stakeholder engagement that are necessary to ensure the resilience of multi-stakeholder vaccine supply chains and not be affected by disruptions such as COVID-19 as it is today. As a result of the study, innovativeness of stakeholders is the most important factor of stakeholder engagement in vaccine supply chains.

“…The risk matrices of the presented approach follow the application of the ISO 3100 and were developed to avoid risk ranking reversal errors as Baybutt reports [69,70], but the limitations of this study are directly related to the design of these risk matrices' development and the uncertain process of evaluation. Previous studies propose the use of fuzzy logic to incorporate uncertainty in the assessment and definition of risk matrices [71][72][73].…”

An Approach to Sustainability Risk Assessment in Industrial Assets

et al. 2021

View full text Add to dashboard Cite

Asset management, as a global process through which value is added to a company, is a managerial model that involves major changes in strategies, technologies, and resources; risk management; and a change in the attitude of the people involved. The growing commitment of companies to sustainability results in them applying this approach to all their activities. For this reason, it is relevant to develop sustainability risk assessment procedures in industrial assets. This paper presents a methodological framework for the inclusion of sustainability aspects in the risk management of industrial assets. This approach presents a procedure to provide general criteria, methodology, and essential mandatory requirements to be adopted for the identification, analysis, and evaluation of sustainability aspects, impacts, and risks related to assets owned and managed by an industrial company. The proposed procedure is based on ISO 55,000 and ISO 31,000 standards and was developed following three steps: a preliminary study, identification of sustainability aspects and sustainability risks/opportunities, and impact assessment and residual risks management. Our results could serve as a model that facilitates the improvement of sustainability analysis risks in industrial assets and could be used as a basis for future developments in the application of the standards to optimize management of these assets.
