Global market and trade utterly need integrated supply chain management systems (SCMSs) to enable organizations to effectively react to increased customer satisfaction. SCM is interpreted as a process establishing network of firms, suppliers, transportation systems, logistics hubs and production units. The major concerns of any SCM is to coordinate and efficiently control material flow, information and finances in order to meet customer demands and overall business objectives. This goal should be reached through supplier performance monitoring and control.
This research puts forward a two-phase sustainable multi-tier supplier selection model for FSC based on an integrated decision analysis under multi-criteria perspectives considering sustainability criteria, suppliers and sub-suppliers. In the first phase, the model estimates supplier selection criteria weights using a combined version of step-wise weight assessment ratio analysis (SWARA) and level based weight assessment (LBWA) in conjunction with D-numbers. In the second phase, Measurement of Alternatives and Ranking according to the COmpromise Solution (MARCOS)-D method is applied to obtain a ranking pre-order of different tier suppliers. Moreover, several sensitivity analyses are carried out in order to examine model reliability. To check application practicability, the proposed model is implemented in a case study of WineSol Corporation in Spain. The proposed model is expected to serve as a kickoff point for developing advanced decision-making models for effectually address multi-tier supplier selection problems under uncertain environment.
Supplier selection in food supply chains (FSCs) is a very challenging subject due to the inherent difficulties, complexities and nature of food industry. Food security and quality are top row topics in today’s world health scenario. During sudden food crisis, it needs extra attention where producers, suppliers, and stakeholders play the most vital roles. Our study contributes to the supply chain sector with the novel and mixed decision-making model and its implementation in food industry.
Our findings identified that ecological practices (oxygen, sulfur dioxide and oak emission) and flexibility of delivery emerged out as the most predominant criteria for the first-tier supplier selection the considered wine industry case study. Viticulture practices, training and trellising, pruning, canopy management and harvest (mechanical or manual) criterion received the least importance according to the experts’ evaluations. Health and safety issues and social responsibility emerged out as the best and least important criteria for the second-tier suppliers. It signifies that lower tier suppliers potentially violate social and environmental standards which can result adversely to upper tier suppliers. Both the manufacturer and upper tier suppliers should exert effort to improve the responsibility of the lower tier suppliers. In the context of global sustainable multi-tier SCs, involvement of first-tier suppliers has become instrumental to achieve socio-economically and environmentally viable SCM systems. Findings from the presented analytical outcomes reveal that the lead organizations should motivate and encourage the role of different tiers separately to reduce information asymmetries, particularly at lower tier levels.
