Abstract:Purpose A supplier may sell not only to one buyer (sole relationship configuration) but also to the buyers competitors (shared relationship configuration) for a specific product category. This study examines the performance implications when suppliers establish shared relationships with the buyer’s competitors.Design/methodology/approach Secondary data are used to test hypotheses relating a supplier’s relationship configurations to its operational performance. A seemingly unrelated regression approach (SUR) is… Show more
“…This involves setting ambitious emission reduction targets, identifying areas where emissions can be reduced and investing in the development and deployment of new technologies that can reduce emissions (Frank et al, 2021). Another implication is the need to collaborate with industry stakeholders, such as airports, manufacturers and fuel suppliers, to develop sustainable ecosystems (Paleari, 2022;Schmelzle and Mukandwal, 2023). Governments can provide support by funding research and development of sustainable aviation technologies, providing incentives for operators to adopt sustainable practices and implementing policies that promote the use of sustainable fuels (Bullerdiek et al, 2021;Santos and Delina, 2021).…”
PurposeWe conduct a multidisciplinary systematic literature review on climate neutrality in the supply chain. While carbon neutrality has gained prominence, our study argues that achieving carbon neutrality alone is not enough to address climate change effectively, as non-CO2 greenhouse gases (GHG) are potent contributors to global warming.Design/methodology/approachWe used multiple databases, including EBSCO, ProQuest, Science Direct, Emerald and Google Scholar, to identify articles related to climate neutrality in the context of non-CO2 gases. A total of 71 articles in environmental science, climate change, energy systems, agriculture and logistics are reviewed to provide insights into the climate neutrality of supply chains.FindingsWe find that, in addition to CO2, other GHG such as methane, nitrous oxide, ozone and fluorinated gases also significantly contribute to climate change. Our literature review identified several key pillars for achieving net-zero GHG emissions, including end-use efficiency and electrification, clean electricity supply, clean fuel supply, “GHG capture, storage and utilization,” enhanced land sinks, reduced non-CO2 emissions and improved feed and manure management.Originality/valueWe contribute to the literature on climate neutrality of supply chains by emphasizing the significance of non-CO2 GHG along with CO2 and highlighting the need for a comprehensive approach to climate neutrality in addressing climate change. This study advances the understanding of climate neutrality of supply chains and contributes to the discourse on effective climate change mitigation strategies. It provides clear future research directions.

“…The two market CSFs comprise integration and external assistance. An interactive supply chain is characterised by stringent stakeholder expectations, robust supplier relationships, and extensive information sharing within the supply chains (Duong et al ., 2023; Schmelzle and Mukandwal, 2022; Kirezieva et al ., 2015b). Improved quality, lower costs, and consistent delivery are the competitive advantages primarily driven by the greater integration between multiple stakeholders in the food supply chain (Nguyen and Li, 2021).…”
PurposeThe growing awareness of climate risks associated with food safety issues has drawn the attention of stakeholders urging the food industry to carry out a sustainable food safety management system (FSMS). This study aims to investigate whether the critical success factors (CSFs) of sustainable FSMS can contribute to achieving climate neutrality, and how the adoption of FSMS 4.0 supported by the Industry Revolution 4.0 (IR 4.0) technologies moderates the impact of the CSFs on achieving climate neutrality.Design/methodology/approachSurvey data from 255 food production firms in China and Vietnam were utilised for the empirical analysis. The research hypotheses were examined using structural equations modelling (SEM) with route analysis and bootstrapping techniques.FindingsThe results show that top management support, human resource management, infrastructure and integration appear as the significant CSFs that directly impact food production firms in achieving climate neutrality. Moreover, the results demonstrate that the adoption of FSMS 4.0 integrated with the three components (ecosystems, quality standards and robustness) significantly moderates the impact of the CSFs on achieving climate neutrality with lower inputs in human resources, infrastructure investment, integration and external assistance, and higher inputs in strengthening food safety administration.Originality/valueThis study provides empirical findings that fill the research gap in understanding the relationship between climate neutrality and the CSFs of sustainable FSMS while considering the moderating effects of the FSMS 4.0 components. The results provide theoretical and practical insights into how the food production sector can utilise IR 4.0 to attain sustainable FSMS for achieving climate neutrality.
“…Liberopoulos and Deligiannis [39] developed an optimal inventory control policy for a supplier when the buyer's purchase decision is influenced by past service levels, which considers the buyer's ordering behavior and the supplier's capacity constraints and trade credit terms, and they showed that the optimal policy can achieve substantial cost savings for both parties. Schmelzle and Mukandwal [40] investigated the impact of supply chain relationship configurations on supplier performance by analyzing buyer-supplier relationships in the aerospace industry, which identified the key dimensions of relationship quality, including trust, communication, and coordination, and they showed that high-quality relationships lead to improved supplier performance in terms of cost, quality, and delivery. Ventura et al [41] studied a multi-period dynamic supplier selection and inventory lot-sizing problem with multiple products in a serial supply chain which incorporated a richer cost structure involving joint replenishment costs for raw material replenishment and production, and an accurate representation of the transportation costs using a vector of full-truck load costs for different size trucks.…”

“…When the production rates of suppliers are greater than or equal to the demand rate, Equations ( 8) and ( 9) can be rewritten as Equations (39) and (40) to represent suppliers' inventory, I S k , k∈ R 1 , and inventory holding cost (IHC S R 1 ), as shown in [1].…”
This paper analyzes different lot-sizing policies for the supplier selection and order allocation problem in a two-stage supply chain. The supply chain consists of multiple candidate suppliers and a single buyer. In this system, selected suppliers produce a product in batches at finite production rates, ship it to the buyer, and the buyer sells it to the market at a constant demand rate. Our goal is to evaluate two lot-sizing policies and select the one that optimizes the supply chain by minimizing the total cost and maximizing supplier efficiency. A bi-objective mixed-integer nonlinear programming (BOMINLP) model is proposed. The first objective consists of the development of a coordination mechanism for supplier selection and order allocation that minimizes the entire supply chain cost, and the second objective comprises a data envelopment analysis (DEA) approach to evaluate the overall performance of suppliers to optimize supplier efficiency. Then, the lot-for-lot and order frequency policies are applied to the BOMINLP model separately to determine the set of selected suppliers as well as the corresponding order quantities and number of orders allocated to each selected supplier per replenishment cycle. Numerical examples that illustrate the solution approach and compare the two lot-sizing policies are provided.
