This study’s main goal was to investigate the effects of sustainable practices on the operational performance of fresh products within Lebanon’s cold chain in terms of operational flexibility, product delivery, quality, and cost. This explanatory research employs a positivist philosophy, logical reasoning, a questionnaire, and a quantitative single-method approach to investigate the research hypotheses. The managers in charge of Lebanon-based businesses that run a cold supply chain for fruits and vegetables made up the target population. A sample of 136 managers filled out the survey. The results revealed a strong positive relationship between sustainable supply chain practices and operational flexibility, product quality, delivery, and cost. Due to their significant influence on operational performance, sustainable supply chain management practices are strongly advised for Lebanese businesses operating in the fruits and vegetables sector. Firms can improve their operational performance while incorporating sustainable practices all along their supply chain. These practices hold accountable all parties concerned with the production and distribution of food in Lebanon. This study contributes to the existing literature by providing empirical evidence on the impact of sustainable practices specifically within the Lebanese cold chain for fresh fruits and vegetables, highlighting its originality in addressing a gap in research on this critical sector.

In recent years, the frequency and extent of supply disruptions have caused serious challenges for supply chains worldwide. To address the resulting supply–demand mismatches, supply chain partners regularly have employed various pricing strategies. First, this study focuses on presenting an optimal pricing model and analysis for a retailer in a monopoly market under supply disruption, which impacts the offerings of two substitutable products with different degrees of greenness. Next, the study presents and analyzes optimal pricing decisions for a retailer in a duopoly market, where two competing retailers have similar product offerings. Results for the monopoly market indicate that as the disruption duration increases, to compensate for the increased waiting time, the price of the greener product should decrease, while the price of the less green product may either increase or decrease depending on the consumer’s sensitivity to price and wait times. In addition, the price difference between the products grows with the disparity in their degrees of greenness. In a duopoly market, the non-disrupted retailer can capitalize on their competitors’ supply issues by adjusting their pricing strategies accordingly. Sensitivity analyses conducted under both monopoly and duopoly markets reveal the impacts of critical factors individually and in combinations. These findings provide actionable insights for retailers to strategically manage product pricing and demand in the face of green supply chain disruptions.

近年来，供应中断的频率和程度给全球供应链带来了严峻挑战。为了应对由此造成的供需错配，供应链合作伙伴经常采用各种定价策略。首先，本研究重点介绍了垄断市场中零售商在供应中断情况下的最优定价模型和分析，供应中断影响了两种不同绿色程度的可替代产品的供应。其次，本研究介绍并分析了双头垄断市场中零售商的最优定价决策，在双头垄断市场中，两个相互竞争的零售商提供类似的产品。垄断市场的研究结果表明，随着中断时间的延长，为了补偿增加的等待时间，绿色程度较高的产品价格应该下降，而绿色程度较低的产品价格则可能上升或下降，这取决于消费者对价格和等待时间的敏感度。此外，产品之间的价格差异会随着绿色程度的不同而扩大。在双头垄断市场中，不受干扰的零售商可以利用竞争对手的供应问题，相应地调整定价策略。在垄断市场和双头垄断市场下进行的敏感性分析揭示了关键因素单独和组合的影响。这些发现为零售商在绿色供应链中断的情况下战略性地管理产品定价和需求提供了可行的见解。

On cost and revenue in circular supply chains: Where to close the loop? 循环供应链中的成本与收益：在哪里实现闭环？

Environmental sustainability is a main research topic in supply chain management, including sustainable, green, closed-loop, and circular supply chain management concepts. A distinctive feature in concept evolution is the increase in tiers of a supply chain included in the reuse or recycling loop. However, most research focuses on dyadic or triadic supply chain structures. Where to close the loop, i.e., where to position the recycler, repurposer, remanufacturer, refurbisher, repairer, and/or reuser, in multi-tier supply chains remains largely unanswered. In response, this study assesses cost and revenue sharing by analytically modeling monetary flows in linear and circular multi-tier supply chains using linear and circular supply chain models and cost-profit theory to derive equations describing monetary flows between the supply chain tiers and external entities. Results show that firms upstream of the loop-closer are negatively affected by the reuse of material, which leads to an increasingly negative impact on the total profit of the supply chain the further downstream the loop-closer is positioned. This has important theoretical and practical implications since upstream suppliers may leave circular supply chains for linear ones if no offset mechanism is provided. There is no difference between linear and circular supply chains for tiers downstream of the loop-closer level. This effect is normally not considered in the literature, focusing on shorter supply chain structures where all firms are connected to the loop. The most important findings and implications are: If the loop-closer is positioned near the OEM tier or external customer, the total personnel, assets costs and total profits decrease in the circular supply chain compared to the linear supply chain. If the loop-closer is positioned at the most upstream tier level, the total personnel and assets costs, and total profits increase.

环境可持续性是供应链管理的一个主要研究课题，包括可持续、绿色、闭环和循环供应链管理概念。概念演变的一个显著特点是再利用或回收循环中供应链层级的增加。然而，大多数研究都集中在二元或三元供应链结构上。在多层次供应链中，回收者、再利用者、再制造者、翻新者、维修者和/或再使用者的位置在哪里，如何实现闭环，这在很大程度上仍是一个未解之谜。为此，本研究利用线性和循环供应链模型以及成本利润理论，对线性和循环多层供应链中的货币流进行分析建模，从而得出描述供应链各层与外部实体之间货币流的方程，以此评估成本和收入的分摊。结果表明，循环闭合商的上游企业受到材料再利用的负面影响，这导致循环闭合商越是处于下游，对供应链总利润的负面影响就越大。这具有重要的理论和实践意义，因为如果不提供抵消机制，上游供应商可能会离开循环供应链，转而进入线性供应链。对于闭环者的下游层级，线性供应链和循环供应链没有区别。文献中通常不考虑这种影响，而只关注所有企业都与环路相连的较短供应链结构。最重要的发现和影响如下如果闭环者的位置靠近原始设备制造商层或外部客户，那么与线性供应链相比，循环供应链的人员、资产成本和利润总额都会下降。如果闭环器位于最上游的层级，则人员、资产总成本和总利润都会增加。

Industrial-scale food production systems often comprise of different parties such as farmers, processors and retailers involved in various activities along the supply chain. These activities are aimed at converting growing items such as crops and livestock into processed and packaged food products that are safe for human consumption. This paper develops inventory models for a three-echelon food supply chain comprising of growing items. The items are grown at the farming echelon, then processed at the processing echelon and finally sold at the retail echelon provided that the various activities that take place at each of those echelons result in the release of carbon emissions. Furthermore, the customers at the retail echelon are both price-conscious and environmentally-conscious and therefore, demand is assumed to be a function of the retail selling price and the amount of carbon emissions released. The inventory system is studied under three different carbon emissions regulations, namely, carbon cap, carbon cap-and-trade and carbon tax regulations. The results from a numerical analysis indicate that the carbon cap-and-trade regulation yields the highest supply chain profit. Moreover, while both carbon cap-and-trade and carbon tax regulations are effective at minimising carbon emissions generated across the supply chain, the cap-and-trade regulation is better at incentivising the supply chain members to reduce their carbon footprint.

工业规模的食品生产系统通常由农民、加工商和零售商等各方组成，参与供应链上的各种活动。这些活动旨在将农作物和牲畜等种植物品转化为可供人类安全消费的加工和包装食品。本文为由种植物品组成的三梯队食品供应链开发了库存模型。这些物品在种植梯队种植，然后在加工梯队加工，最后在零售梯队销售，条件是在每个梯队进行的各种活动都会导致碳排放。此外，零售梯队的客户既注重价格又注重环保，因此假定需求量是零售价格和碳排放量的函数。研究了三种不同碳排放法规下的库存系统，即碳排放上限、碳排放上限与交易和碳税法规。数值分析结果表明，碳排放总量控制与交易法规产生的供应链利润最高。此外，虽然碳限额交易和碳税法规都能有效减少供应链中产生的碳排放，但碳限额交易法规更能激励供应链成员减少碳足迹。

Sustainability challenges have led to a growing interest in agri-food sustainability performance and the role of ownership structures in it. Ownership has significant implications by defining how owners reflect their goals and ownership costs into firm objectives, decision time horizons, risk preferences, and interactions with supply chain partners. Current literature shows conflicting results on the relationship and a lack of consistent definitions and measurements. Previous reviews have focused on one ownership structure, one sustainability pillar, have not addressed theory application or the context of the agri-food sector. This paper addresses this fragmented literature by providing a systematic assessment of conceptualisations and measures, theories used, linking empirical evidence and theoretical arguments to understand how ownership explains differences in sustainability performance. A systematically rigorous PRISMA methodology utilising thematic and narrative synthesis is applied. The synthesis reveals that ownership can positively affect one area of sustainability but negatively affect another. Theories explain how ownership shapes unique firm characteristics that, in turn influence sustainability performance. Firm goals, capital structure, governance system, and business strategy are significant explanatory factors for sustainability performance. The paper concludes with suggestions for future research to aid comparison between studies and generalisation of conclusions.

可持续发展的挑战使人们越来越关注农业食品的可持续发展绩效以及所有权结构在其中的作用。所有权具有重要意义，它界定了所有者如何将其目标和所有权成本反映到公司目标、决策时间跨度、风险偏好以及与供应链合作伙伴的互动中。目前的文献显示，关于这种关系的结果相互矛盾，缺乏一致的定义和衡量标准。以往的综述侧重于一种所有权结构、一个可持续性支柱，并未涉及理论应用或农业食品行业的背景。本文针对这些零散的文献，对概念和测量方法、所用理论进行了系统评估，将经验证据和理论论点联系起来，以了解所有权如何解释可持续性绩效的差异。本文采用了系统严谨的 PRISMA 方法，利用了专题和叙事综合法。综合结果表明，所有权可以对可持续发展的一个领域产生积极影响，但对另一个领域产生消极影响。相关理论解释了所有权如何形成独特的企业特征，进而影响可持续发展绩效。企业目标、资本结构、治理体系和业务战略是可持续发展绩效的重要解释因素。本文最后对未来的研究提出了建议，以帮助比较不同的研究并推广结论。

With the contemporary environmental challenges driven by global warming, industries must prioritize aligning their business operations with responsibilities toward society, environment, and economy, emphasizing the crucial role of enablers in facilitating the adoption of Sustainable Supply Chain Management (SSCM), particularly in emerging economies. While previous studies mostly identified the SSCM enablers and found out their association with each other, however, to address this gap, this study aims to explore the influence of the enablers (policy, technology, environment, finance, and human resource) on the adoption of SSCM using Diffusion of Innovation (DOI) theory as a theoretical lens in the context of a developing economy by Structural Equation Modelling (SEM) approach. The findings suggest that policy and the environment category enablers significantly influence the adoption of SSCM. Insufficient funds and lack of academic and training resources pertaining to the supply chain, the influence of technology, finance, and human resource enablers are found to be non-significant, particularly in the developing country context. This research contributes to sustainability literature by providing empirical evidence on the influence of enablers in SSCM adoption, offering valuable guidance to supply chain managers and regulatory bodies for formulating effective strategies and policies.

随着全球变暖带来的当代环境挑战，各行业必须优先考虑将其业务运营与对社会、环境和经济的责任结合起来，强调促进因素在推动采用可持续供应链管理（SSCM）方面的关键作用，尤其是在新兴经济体。以往的研究大多确定了可持续供应链管理的促进因素，并发现了它们之间的关联，然而，为了弥补这一不足，本研究旨在以创新扩散（DI）理论为理论视角，通过结构方程建模（SEM）方法，在发展中经济体的背景下，探讨促进因素（政策、技术、环境、金融和人力资源）对采用可持续供应链管理的影响。研究结果表明，政策和环境类促进因素对采用 SSCM 有重大影响。研究发现，资金不足、缺乏与供应链相关的学术和培训资源，以及技术、金融和人力资源推动因素的影响并不明显，尤其是在发展中国家。这项研究为可持续发展方面的文献做出了贡献，它提供了实证证据，说明了采用供应链管理的有利因素的影响，为供应链管理者和监管机构制定有效的战略和政策提供了宝贵的指导。

This study contributes to the fish reverse supply chain due to a lack of social, economic and environmental impacts. This study aims to develop a mathematical model for the fish reverse supply chain with a multi-echelon, multiple periods, and products. The model optimizes total profit, job opportunities, and carbon emissions simultaneously. The proposed model provides social-economic insight for governments and industries to understand the increasing job opportunities if fish gelatine and powder industries can process fish waste. A sensitivity analysis shows that the supply of raw fish, selling prices, and purchasing costs are sensitive to total profit, carbon emissions, and job opportunities. The results show that the total profit for five months is USD 1,437,837, and the most significant contribution to the total cost is the costs of purchasing, emission costs, and production costs, which are 43.83%, 24.02%, and 18.15%, respectively. These results can assist managers in making optimal decisions regarding raw fish supply, halal fish gelatine, and fish powder production, impacting strategic, tactical, and operational policies.

由于缺乏社会、经济和环境影响，本研究有助于水产品逆向供应链。本研究旨在建立一个多梯队、多时段、多产品的水产品逆向供应链数学模型。该模型可同时优化总利润、就业机会和碳排放。所提出的模型为政府和行业提供了社会经济洞察力，使其了解如果鱼明胶和鱼粉行业能够处理鱼类废弃物，将会增加的就业机会。敏感性分析表明，原料鱼的供应、销售价格和采购成本对总利润、碳排放和就业机会都很敏感。结果表明，五个月的总利润为 1,437,837 美元，对总成本贡献最大的是采购成本、排放成本和生产成本，分别为 43.83%、24.02% 和 18.15%。这些结果可以帮助管理者在原料鱼供应、清真鱼明胶和鱼粉生产方面做出最佳决策，对战略、战术和运营政策产生影响。

A sensitivity analysis shows that the supply of raw fish, selling prices, and purchasing costs are sensitive to total profit, carbon emissions, and job opportunities. The results show that the total profit for five months is USD 1,437,837, and the most significant contribution to the total cost is the costs of purchasing, emission costs, and production costs, which are 43.83%, 24.02%, and 18.15%, respectively. These results can assist managers in making optimal decisions regarding raw fish supply, halal fish gelatine, and fish powder production, impacting strategic, tactical, and operational policies.</div></div>","PeriodicalId":100253,"journal":{"name":"Cleaner Logistics and Supply Chain","volume":"13 ","pages":"Article 100189"},"PeriodicalIF":6.9,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142707076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the application of a comprehensive framework for implementing digital strategies towards achieving net-zero emissions in Spanish manufacturing firms. It explores the adoption of digitally enabled and digital-first strategies in 354 medium-sized companies, utilizing Internet of Things (IoT) and Artificial Intelligence (AI) technologies to augment and reinvent environmental management practices. Digitally enabled strategies are found to be prevalent, optimizing existing processes through IoT for resource conservation and predictive maintenance. A modest yet growing number of firms adopt digital-first strategies, integrating AI to create innovative pathways for energy use optimization and waste reduction. However, a subset of firms remains reliant on traditional methods, indicating significant potential for digital integration. The paper highlights the strategic importance of digital tools in enhancing operational efficiencies and developing new, inherently sustainable business models. It emphasizes the need for an integrated approach that combines the strengths of digital innovation with traditional management to drive the industry towards a sustainable and net-zero future. The framework provides a nuanced classification of digital strategies and their contribution to net-zero objectives, offering insights into the effectiveness of these practices across various industrial sectors.

Sustainable supply chain management (SSCM) has become the key concept for every industry in managing their supply chain system by focusing on three aspects: economics, social, and environmental. Even though the implementation of SSCM will help the industry increase the efficiency of supply chain management, some challenges make the firms cannot implement the SSCM concept well and unsuccessful. The challenges of SSCM implementation need to be identified and managed to overcome these challenges and increase the efficiency of SSCM management. Therefore, this study aims to identify and analyze the challenges to SSCM implementation in the case of the local plastic recycling business in Thailand. The questionnaire was used to collect data from plastic recycling business experts. The best-worst method was used to analyze the significant challenges and prioritize ranking the SSCM implementation challenges. The results of this research found that management challenges are the first rank which lack of the policy and strategy for SSCM is a critical sub-challenge in the management dimension. The financial challenges are the second rank for SSCM due to the local plastic recycling business still being faced with financial constraints, which is the critical sub-challenges in the financial dimension, and the technology challenges are ranked last, which presented that it is less critical for SSCM in the local scale. Furthermore, the research conclusion and the guideline for the research direction of this research are presented.

可持续供应链管理（Sustainable Supply Chain Management，SSCM）已成为各行各业管理其供应链系统的关键概念，其重点在于经济、社会和环境三个方面。尽管实施可持续供应链管理有助于提高行业供应链管理的效率，但一些挑战也使企业无法很好地实施可持续供应链管理理念，导致实施不成功。要克服这些挑战，提高 SSCM 管理的效率，就必须识别和管理 SSCM 实施过程中遇到的挑战。因此，本研究旨在以泰国当地塑料回收企业为例，识别和分析实施 SSCM 所面临的挑战。本研究采用问卷调查的方式收集塑料回收企业专家的数据。采用最佳-最差法分析重大挑战，并对 SSCM 实施挑战进行优先排序。研究结果发现，管理方面的挑战排在第一位，而缺乏 SSCM 政策和战略则是管理方面的一个关键子挑战。财务挑战排在第二位，原因是本地塑料回收企业仍面临财务限制，这是财务维度中的关键子挑战；技术挑战排在最后，这表明在本地范围内，技术对 SSCM 的关键性较低。此外，还提出了本研究的结论和研究方向指南。

The transition to battery electric vehicles (BEVs) challenges current logistics systems and actors’ business models, especially logistics service providers (LSP). In response, the purpose of this study is to increase the understanding of the characteristics of critical factors in business models for LSPs when adapting electrified freight. A structured interview study targeting LSPs that are operating BEVs has been carried out. Eleven factors deemed as critical were identified in business model components, pointing to a need to take a holistic view when designing business models for electrified freight. Furthermore, four themes are identified that address how characteristics of logistics systems change when BEVs are adopted. This includes changes in uncertainty and complexity. To comply with the increased dynamic, the paper proposes a conceptual framework which captures the evolvement of the critical factors when the market matures by classifying them as constant, fading, adopting, and emerging. The critical factors and their evolvement can be used as guidelines for practitioners and researchers in their development of sustainable business models in the transfer towards electrified freight.

向电池电动汽车（BEV）的过渡对当前的物流系统和参与者的商业模式提出了挑战，尤其是物流服务提供商（LSP）。为此，本研究旨在进一步了解物流服务供应商在适应电气化货运时，其商业模式中关键因素的特点。我们针对正在运营 BEV 的物流服务供应商开展了一项结构化访谈研究。研究发现，商业模式中存在 11 个关键因素，这表明在设计电气化货运的商业模式时，需要从全局出发。此外，还确定了四个主题，涉及采用 BEV 时物流系统的特征如何变化。这包括不确定性和复杂性的变化。为了适应动态变化的增加，本文提出了一个概念框架，通过将关键因素分为恒定、消退、采用和新兴四类，来捕捉市场成熟时关键因素的演变。这些关键因素及其演变可作为从业人员和研究人员在向电气化货运转移过程中开发可持续商业模式的指导方针。
