    This research was conducted on industrial agriculture in Indonesia. Risk analysis was carried out based on previous research. One source of risk was obtained, namely raw materials that did not meet specifications, which was then proposed to be mitigated by evaluating supplier performance. This activity involves a lot of data, requiring efficient and effective data storage and access. The level in the simulation layout includes analysing system needs, using problem diagrams, compiling activity diagrams, deciding subprocesses, and filtering information. The analysis is carried out by comparing the use of supply chains with Blockchain and without Blockchain, which is then obtained to determine whether there is an increase. A sequentially stored data scenario describes a situation when the transaction process is in progress and is stored sequentially according to the process that occurs. Storing data in groups explains a problem when a transaction has been completed and stored in groups with similar data, making it easier to track specific data. In this regard, a simulation will be carried out using a website, namely a blockchain demo. The design stage starts with identifying system requirements, creating use case diagrams, compiling activity diagrams, determining subprocesses, and selecting information. The simulation results obtained will be analysed to determine the feasibility of Blockchain as a means of supporting risk mitigation related to data using aspects, including security, trust, traceability, sustainability, and costs.

    在意大利,葡萄酒供应链是国家农业食品体系的基石,也是整个经济的驱动力。这项研究的目的是通过对多个案例研究的分析来绘制意大利葡萄酒公司的概况。这项研究特别关注马尔凯地区的公司,调查他们的特点和供应链,特别关注所采用的产品和系统认证,实施的营销政策,以及企业与机构的关系。共有18家公司参与了这项研究。研究的主要数据是通过持续1小时的半结构化访谈收集的,根据面试协议.结果表明,葡萄酒部门的供应链配置较短,即使合作社充当聚合者。规模小,财政资源有限,特别难以在参考范围之外推广葡萄酒,地方一级缺乏网络战略。许多公司认为有机认证是一个缺点,因为它倾向于与大型葡萄酒行业同源生产,使产品自然,典型性,手艺消失了。
    In Italy, the wine supply chain is a cornerstone of the national agri-food system and a driving force for the entire economy. The aim of this study is to map the profile of Italian wine companies through the analysis of multiple case studies. The study focuses specifically on companies in the Marche region, investigating their features and supply chain, with a specific focus on product and system certification adopted, marketing policies implemented, and the businesses\' relationship with institutions. A total of 18 companies participated in the study. The primary data for the research was collected through semi-structured interviews lasting 1 h, based on an interview protocol. The results show that the supply chain for the wine sector is configured to be short, even when cooperatives act as an aggregator. The small size and limited financial resources make it particularly difficult to promote the wine outside its reference context, and there is a lack of a network strategy at the local level. Many companies consider organic certification a disadvantage since it tends to homologate production to the large wine industries, making the product\'s naturalness, typicality, and craftsmanship disappear.

    背景:在过去的两年中,COVID-19大流行给医疗保健行业带来了巨大压力。需求有所增加,同时,供应短缺。这表明,医疗保健行业的供应链管理不能被视为理所当然。此外,医疗保健行业也面临着其他重大挑战,如当前劳动力市场短缺。在文学中,物联网(IoT)被强调为一种有效的工具,可以构建更有弹性和更高效的供应链,以应对这些挑战。尽管在供应链管理中使用物联网已经在其他类型的供应链中得到了广泛的研究,它在医疗保健供应链中的使用在很大程度上被忽视了。鉴于医疗保健供应链,与其他人相比,更复杂,压力越来越大,有必要更深入地了解物联网带来的机遇。
    目的:本研究旨在通过识别和排名在医疗保健供应链中实施物联网的驱动因素和障碍来解决这一研究差距。
    方法:我们进行了2期研究。在第一,探索阶段,总共进行了12次半结构化访谈,以确定驾驶员和障碍。在第二个,确认阶段,在一项调查中,共有26名医疗保健供应链专业人员被要求对驱动因素和障碍进行排名。
    结果:结果表明,存在多种财务,操作,与战略相关的,以及实施物联网的供应链相关驱动因素。同样,有各种各样的金融,与战略相关的,供应链相关,与技术相关的,和用户相关的障碍。研究结果还表明,与供应链相关的驱动因素(例如,提高透明度,可追溯性,以及与供应商的合作)是最强的驱动力,而财务障碍(例如,高的实施成本和构建商业案例的困难)是需要克服的最大障碍。
    结论:本研究的结果通过经验识别物联网实施的最重要驱动因素和障碍,增加了有关医疗保健供应链中物联网的有限文献。驱动因素和障碍的排名为打算在医疗保健供应链中实施物联网的从业者和医疗保健提供者领导者提供了指导。
    Over the past 2 years, the COVID-19 pandemic has placed enormous pressure on the health care industry. There has been an increase in demand and, at the same time, a shortage of supplies. This has shown that supply chain management in the health care industry cannot be taken for granted. Furthermore, the health care industry is also facing other major challenges, such as the current labor market shortage. In the literature, the Internet of Things (IoT) is highlighted as an effective tool to build a more resilient and efficient supply chain that can manage these challenges. Although using IoT in supply chain management has been extensively examined in other types of supply chains, its use in the health care supply chain has largely been overlooked. Given that the health care supply chain, compared to others, is more complex and is under growing pressure, a more in-depth understanding of the opportunities brought by IoT is necessary.
    This study aims to address this research gap by identifying and ranking the drivers of and barriers to implementing IoT in the health care supply chain.
    We conducted a 2-stage study. In the first, exploratory stage, a total of 12 semistructured interviews were conducted to identify drivers and barriers. In the second, confirmatory stage, a total of 26 health care supply chain professionals were asked in a survey to rank the drivers and barriers.
    The results show that there are multiple financial, operational, strategy-related, and supply chain-related drivers for implementing IoT. Similarly, there are various financial, strategy-related, supply chain-related, technology-related, and user-related barriers. The findings also show that supply chain-related drivers (eg, increased transparency, traceability, and collaboration with suppliers) are the strongest drivers, while financial barriers (eg, high implementation costs and difficulties in building a business case) are the biggest barriers to overcome.
    The findings of this study add to the limited literature regarding IoT in the health care supply chain by empirically identifying the most important drivers and barriers to IoT implementation. The ranking of drivers and barriers provides guidance for practitioners and health care provider leaders intending to implement IoT in the health care supply chain.

    实现可持续发展目标(SDGs)和碳中和目标,中国政府一直在采取总量管制和交易监管来遏制碳排放。在这样的背景下,供应链中的成员应该适当安排他们的碳减排和营销决策,以获得最佳利润,特别是当有利事件可能发生时,这往往会提升商誉和市场需求。然而,当进行限额与交易监管时,该事件可能对他们没有好处,因为市场需求的增加总是与碳排放的增加有关。因此,关于成员如何调整他们的碳减排和营销决策,同时设想限额和交易监管下的有利事件的问题出现了。鉴于事件在计划期间随机发生,我们使用马尔可夫随机过程来描述事件,并使用差分博弈方法来动态研究这个问题。在对模型进行求解和分析之后,我们得到以下结论:(1)有利事件的发生将整个计划期分为两种制度,供应链成员应在各制度下做出最优决策,以实现整体利润最大化。(2)潜在的有利事件将提升营销和碳减排力度,以及事件发生前的商誉水平。(3)如果单位排放值相对较低,有利事件将有助于减少排放量。然而,如果单位排放值相对较大,那么有利事件将有助于增加排放量。
    To achieve SDGs (sustainable development goals) and carbon neutrality goals, the Chinese government have been adopting the cap-and-trade regulation to curb carbon emissions. With this background, members in the supply chain should properly arrange their carbon reduction and marketing decisions to acquire optimal profits, especially when the favorable event may happen, which tends to elevate goodwill and the market demand. However, the event may not be of their benefit when the cap-and-trade regulation is conducted, since the increase in market demand is always associated with an increase in carbon emissions. Hence, questions arise about how the members adjust their carbon reduction and marketing decisions while envisioning the favorable event under the cap-and-trade regulation. Given the fact that the event occurs randomly during the planning period, we use the Markov random process to depict the event and use differential game methodology to dynamically study this issue. After solving and analyzing the model, we acquire the following conclusions: (1) the occurrence of the favorable event splits the whole planning period into two regimes and the supply chain members should make optimal decisions in each regime to maximize the overall profits. (2) The potential favorable event will elevate the marketing and carbon reduction efforts, as well as the goodwill level before the event. (3) If the unit emissions value is relatively low, the favorable event will help to decrease the emissions quantity. However, if the unit emissions value is relatively large, then the favorable event will help to increase the emissions quantity.

    本文提出了COVID-19大流行期间绿色闭环供应链网络(GCLSCN)的新数学模型。建议的模型可以解释COVID-19爆发期间环境(最大限度地减少二氧化碳排放)和经济(最大限度地减少总成本)之间的权衡。考虑到疫情期间的卫生指南有助于我们设计新的可持续卫生供应链(SC)。该模型对成本结构敏感。成本包括两部分:不考虑冠状病毒大流行的正常成本和考虑冠状病毒的成本。本文的经济新颖性方面是卫生成本。它包括消毒和消毒剂费用,个人防护设备(PPE)成本,COVID-19测试,教育,药物,疫苗,疫苗接种费用。本文提出了在大流行期间设计GCLSCN的多目标混合整数规划(MOMIP)问题。优化过程使用标量化方法,即加权求和法(WSM)。计算优化过程通过Lingo软件进行。由于COVID-19大流行的新近发生,还有很多研究空白。我们对这项研究的贡献如下:(I)设计了一个绿色供应链(GSC)模型,并显示了在COVID-19大流行和封锁期间经济和环境方面的更好权衡,(ii)设计卫生供应链,(三)提出了COVID-19疫情期间经济方面的新指标,和(Iv)发现了COVID-19和封锁的积极(减少二氧化碳排放)和消极(增加成本)影响。因此,这项研究设计了一种新的卫生模型来填补COVID-19疾病灾难的这一空白。拟议网络的结果表明,在COVID-19大流行期间,SC变得更加绿色。在COVID-19大流行期间,网络的总成本增加了,但是封锁对排放和空气质量有直接的积极影响。
    This paper presents a new mathematical model of the green closed-loop supply chain network (GCLSCN) during the COVID-19 pandemic. The suggested model can explain the trade-offs between environmental (minimizing CO2 emissions) and economic (minimizing total costs) aspects during the COVID-19 outbreak. Considering the guidelines for hygiene during the outbreak helps us design a new sustainable hygiene supply chain (SC). This model is sensitive to the cost structure. The cost includes two parts: the normal cost without considering the coronavirus pandemic and the cost with considering coronavirus. The economic novelty aspect of this paper is the hygiene costs. It includes disinfection and sanitizer costs, personal protective equipment (PPE) costs, COVID-19 tests, education, medicines, vaccines, and vaccination costs. This paper presents a multi-objective mixed-integer programming (MOMIP) problem for designing a GCLSCN during the pandemic. The optimization procedure uses the scalarization approach, namely the weighted sum method (WSM). The computational optimization process is conducted through Lingo software. Due to the recency of the COVID-19 pandemic, there are still many research gaps. Our contributions to this research are as follows: (i) designed a model of the green supply chain (GSC) and showed the better trade-offs between economic and environmental aspects during the COVID-19 pandemic and lockdowns, (ii) designed the hygiene supply chain, (iii) proposed the new indicators of economic aspects during the COVID-19 outbreak, and (iv) have found the positive (reducing CO2 emissions) and negative (increase in costs) impacts of COVID-19 and lockdowns. Therefore, this study designed a new hygiene model to fill this gap for the COVID-19 condition disaster. The findings of the proposed network illustrate the SC has become greener during the COVID-19 pandemic. The total cost of the network was increased during the COVID-19 pandemic, but the lockdowns had direct positive effects on emissions and air quality.

    可持续供应链管理(SSCM)近年来受到学术界和工业界的广泛关注。然而,越来越多的研究衡量供应链的社会可持续性绩效以及讨论社会和经济可持续性之间的相互关系。Further,测量没有充分利用关键绩效指标(KPI)归因于缺乏对供应链社会可持续绩效的精确定量指标的理解。为了弥合这个差距,这项研究从需求规划的角度分析了社会和经济可持续性表现,创新,制造,金融,销售和客户关系,分销和交付以及合规性。提出了一个框架来定位关键指标以评估社会可持续供应链(SSC)绩效。设计了一种混合模糊-AHP-DEMATEL-VIKOR方法来研究供应链的社会可持续性。给出了数据分析和案例研究,以验证和支持所提出方法的可行性和效力。我们提出的模型的鲁棒性是通过灵敏度分析来执行的。从拟议的框架来看,需求规划、分配和交付被认为是经济和社会层面最关键的标准,分别。
    Sustainable supply chain management (SSCM) has received extensive attention by academia and industries recently. However, there are increasing yet still scarce studies measuring the social sustainability performance of supply chain and discussing the interrelationship between social and economic sustainability. Further, the measurement does not fully utilize key performance indicators (KPIs) attributing to the lack of understanding of precise quantitative gauge of the supply chain social sustainable performance. To bridge this gap, this study analyses the social and economic sustainability performance in terms of demand planning, innovation, manufacturing, finance, sales and customer relationship, distribution and delivery and compliance. A framework is proposed to locate key metrics to evaluate the social sustainable supply chain (SSC) performance. A hybrid fuzzy-AHP-DEMATEL-VIKOR method is designed to investigate the social sustainability of supply chain. Data analysis and a case study are given to validate and support the feasibility and potency of the proposed approach. The robustness of our proposed model is executed via sensitivity analysis. From the proposed framework, demand planning and distribution and delivery are found to be the most critical criteria in economic and social dimension, respectively.

    由于化石燃料对环境的破坏性影响,现在有人建议使用可再生能源。此外,由于太阳能的使用增加和太阳能电池供应链(SCSC)的预防,这条链条主要由政府资助。在这项研究中,我们对两级SCSC的供给侧和需求侧政策进行数学建模,考虑到国内外供应商之间的竞争以及政府在供应方补贴政策下的干预,以支持SCSC成员并通过需求方补贴政策为客户提供资金。本文的目的是研究政府在供应方和需求方政策下的干预对支持SCSC成员和鼓励客户增加太阳能电池板使用的影响。此外,这项研究探索了改善和促进SCSC的最佳政策。在现实世界中,供给侧和需求侧的政策都将有助于工业工厂,发电厂,和家庭加强利用太阳能发电。这项研究是用一个真实的例子进行调查的,结果表明,供给侧政策下的效率比需求侧政策下的效率高出约7%。供给侧政策下的价格比需求侧政策下的价格低大约10%。供方政策下的成员利润比需求方政策下的成员利润高出约5%。根据真实的例子,需求侧政策下政府的效用比供给侧政策下政府的效用小近1%。最后,所提出的模型考虑了关键发现。
    Due to the destructive effects of fossil fuels on the environment, using renewable energies has nowadays been suggested. In addition, because of the increased use of solar energy and the prevention the solar cell supply chain (SCSC), this chain is mainly supported by government funding. In this study, we mathematically model both supply-side and demand-side policies for a two-echelon SCSC, considering the competition between domestic and foreign suppliers as well as government intervention under the supply-side subsidy policies to support SCSC members and finance the customers through demand-side subsidy policies. The aim of this paper is to investigate the effects of government intervention under the supply-side and demand-side policies on supporting the members of SCSC and encouraging customers to increase the use of solar panels. In addition, this study explores the best policy for improving and promoting SCSC. In the real world, both supply-side and demand-side policies will help industrial factories, power plants, and households to enhance the use of solar energy for producing electricity. This study has been investigated using one real example, whose results show that the efficiency under the supply-side policy is about 7% more than the efficiency under the demand-side policy. The price under the supply-side policy is roughly 10% less than the price under the demand-side policy. The members\' profit under the supply-side policy is approximately 5% bigger than the one under the demand-side policy. According to real examples, the government\'s utility under the demand-side policy is nearly 1% smaller than the government\'s utility under the supply-side policy. Finally, key findings are considered for the proposed model.

    作为一个污染行业,涂料的绿色转型受到中国政府的高度关注。为探讨政府在涂料行业绿色转型过程中的作用,本文构建了“政府-制造企业-应用企业”的绿色治理演化博弈模型,并研究了三方之间的复杂互动机制。然后,运用演化博弈理论分析了涂料行业绿色治理(传统技术—绿色转型—协同治理)三个阶段中三方博弈平衡点的渐近稳定性条件和演化稳定性策略。最后,通过数值模拟对模型进行了验证,讨论了主观参数的变化对进化博弈的影响。结果表明:(1)政府治理强度与抽查频率和惩罚系数有关,当治理强度适度时,进化趋于平衡。(2)博弈主体策略选择的演化趋势也取决于政府的惩罚。受到惩罚的制造企业绿色转型的可能性更大。(3)产品的绿色补贴系数和绿色度对游戏玩家的战略选择也有较大影响。
    As a polluting industry, the green transformation of coatings is highly concerned by the Chinese government. In order to explore the role of government in the process of green transformation of coating industry, this paper constructs a green governance evolutionary game model of \"government-manufacturing companies-application companies,\" and the complex interaction mechanism among the three parties is studied. Then, the evolutionary game theory is used to analyze the asymptotic stability conditions and evolutionary stability strategies of the equilibrium point of the tripartite game in the three stages of green governance in the coating industry (traditional technology-green transformation-collaborative governance). Finally, the model was verified by numerical simulation, and the influence of the changes of subjective parameters on the evolutionary game was discussed. The results show that (1) the intensity of government governance is related to the frequency of spot checks and punishment coefficients, and the evolution tends to be balanced when the intensity of governance is moderate. (2) The evolutionary trend of the game\'s main players\' strategy selection also depends on the government\'s punishment. There is greater probability of green transition of manufacturing companies under punishment. (3) The green subsidy coefficient and the green degree of the product also have a greater impact on the strategic choice of the game player.
