Achieving a supply chain that is resilient to potential unforeseen disruptions (e.g., strikes, floods, tsunamis, etc.) remains one of the vital concerns of decision makers (DMs). To build up a reactive supply chain plan towards resilience, the purchasing department needs to pay the strictest attention to sourcing decisions. This study contributes to the literature through developing an efficient resilient supplier selection approach based on a new holistic framework that enables the identification of key resilience pillars (RPs) and traditional business criteria (TBC) in light of a thorough literature review and experts’ opinions. To this end, the relative importance of TBC/RP was measured by applying the DEMATEL (D) method. This was followed by the application of MABAC-OCRA-TOPSIS-VIKOR (MOTV) methods to verify the suppliers’ ranking. Furthermore, the Spearman rank correlation coefficient (SRCC) approach was used to investigate the correlation among the suppliers’ ranking, revealed via the four methods. In this work, a real sourcing problem of scrap metal for a steel manufacturing company was solved to prove the applicability of the proposed approach. The research outcome revealed that the TBC of “trust” is the most important criterion, followed by the “cost”, leaving the “geographical location” criterion as the least important one. In this context, the RP of “flexibility” attained the highest relative weight compared to “agility”, which secured the lowest weight. The results also showed “absolute” correlation among MABAC, VIKOR, and OCRA compared to “very strong” correlation between TOPSIS and the others. This research can support supply chain managers to achieve supply chain systems that reduce not only sourcing costs, but also potential losses because of disrupting threats, by building resilient supply chains.

Food waste has a wide range of negative implications on the environment, economy and society and it is a concern for the catering industry and a growing percentage of the population. This work investigates the main root causes of food waste, in the catering industry, based on data collected from 32 businesses located in Wales, UK. The research uses multi-criteria decision making methods (Analytic Hierarchy Process and Decision Making Trial and Evaluation Laboratory), to analyse the degrees of importance and interrelationships of food waste enablers using holistic cause and effect diagrams and priority ranking. The analysis identifies critical food waste enablers in different dimensions (procurement and storage, processing, operation strategy, people and consumer) for various business outlets. Those causes can be addressed with limited resources and create the maximum value for the business and environment. The methodology could be used as a strategic tool by businesses in daily operations by managing and controlling identified root causes.

The vast majority of current literature handle supplier selection problem considering green and resilience aspects, bifurcately. But green supply chain performance is subject to disruption by internal /or external events. This initiates the need for a merged management approach to establish green and resilient supply chains, that we hereby present it as “gresilient” supply chain management. At the institutional level, the integration of measures of these two paradigms into supply chain processes frets substantial management challenges. This research intends to overcome some of these challenges in exploring, identifying and quantifying resiliency and greenness performance in supplier selection context. To this end, this work aims to: (1) explore and analyse the need and complementarities for or between resiliency and greenness in supply chain context; (2) identify the criteria of greenness and resiliency (a new framework for resilient supplier was developed in considering criteria of development, agility, robustness, sensing and flexibility (DARSF) into a unified framework; (3) quantify the gresilience performance measures by proposing a quantitative approach to evaluate the relative importance of the ‘gresilience’ criteria and suppliers’ gresilience performance via multi-criteria decision making (MCDM) algorithms. The main findings are: (i) a holistic gresilient supplier evaluation framework; and (ii) a user-friendly decision-making tool to gauge gresilience performance of suppliers. This research provides them with a clear insight towards gresilient advantages in today’ highly competitive business. This research bridges the literature gap in addressing the supplier selection problem from resiliency and greenness perspectives, jointly.
