ABSTRACT Supply chain price variability, also known as the “Bullwhip effect in Pricing (BP),” refers to the absorption or amplification of the variability of prices from one stage to another in a supply chain. This article derives analytical conditions that result in BP considering a buyback contract and conducts numerical simulations to gain further insights. For this, a joint price and replenishment setting newsvendor model with a wholesale-Stackelberg game is considered. Two demand types (linear and isoelastic) are analyzed along with uniformly and normally distributed additive and multiplicative uncertainties. The outcome of this research reveals that the main influential factors that affect BP are the structure and error type of the demand functions. Absorption (amplification) in price fluctuations occurs for linear (isoelastic) demand cases. Moreover, the price variances and BP ratios differ under the buyback and wholesale-price-only cases. The overall results help understand the fluctuation of market prices under various conditions.
摘要供应链价格可变性,也称为“定价中的牛鞭效应(BP)”,是指在供应链的一个阶段到另一个阶段,价格的可变性被吸收或放大。本文推导了导致英国石油公司考虑回购合同的分析条件,并进行了数值模拟以获得进一步的见解。为此,考虑了一个具有批发Stackelberg博弈的定价和补货联合新闻供应商模型。分析了两种需求类型(线性和等弹性)以及均匀正态分布的加法和乘法不确定性。研究结果表明,影响BP的主要影响因素是需求函数的结构和误差类型。价格波动的吸收(放大)发生在线性(等弹性)需求的情况下。此外,在回购和仅批发价格的情况下,价格差异和BP比率不同。总体结果有助于理解不同条件下市场价格的波动。

ABSTRACT In this paper, a hierarchical heuristic algorithm is proposed to allocate order quantities to suppliers and determine the best lot sizing for each supplier. Pre-defined policies are first implemented to generate the initial order allocation to suppliers. The solutions are then modified by reducing the gap of the least satisfying level to search for a compromised solution, and this process is repeated until no further improvement can be made. The fine-tuning process finally reduces the gap between the two consecutive order allocation schemes. In the second level, a dynamic programming approach is modified to determine the best lot-sizing plan and compensate for the loss of quality and late delivery. The contributions of this work are to develop not only the best order allocation plan instead of supplier selection but also effective lot sizing plan that can reduce supply uncertainties. Experiments are tested to confirm the performance of the proposed method. Graphical Abstract
摘要本文提出了一种分层启发式算法来分配供应商的订单数量,并确定每个供应商的最佳批量。首先实现预定义的策略来生成分配给供应商的初始订单。然后通过缩小最不满意水平的差距来修改解决方案,以寻找折衷的解决方案,并重复此过程,直到无法进行进一步改进。微调过程最终减少了两个连续订单分配方案之间的差距。在第二层,修改了动态规划方法,以确定最佳批量计划并补偿质量损失和延迟交货。该工作的贡献在于,不仅制定了最佳的订单分配计划,而不是供应商的选择,而且还制定了有效的批量计划,以减少供应的不确定性。实验验证了该方法的有效性。图形抽象

ABSTRACT Circular supply chain management (CSCM) is a process used to design the supply chain by recycling, remanufacturing or refurbishing, repairing, and reusing products However, no study has been encountered in the literature that analyzes CSCM barriers in the air conditioning sector. Hence, this study is aimed to investigate the barriers to CSCM adoption in the air conditioning industry. A case study was conducted on a company operating in the global air conditioning sector. Initially, literature review and expert opinions have been used to identify essential barriers. Later, 6 main barriers and 21 sub-barriers were ranked using Analytical Hierarchy Process (AHP) method based on the interval type-2 fuzzy sets. The findings indicate that “Regulatory” is the most crucial, and “Operational” is the least important main barrier. The findings of the study would be useful for practitioners and policymakers to focus on the most prominent barriers in the air conditioning supply chains. GRAPHICAL ABSTRACT

ABSTRACT Sustainable production is proposed to guide manufacturers in achieving sustainable development goals. Although previous studies have developed diverse metaheuristics algorithms in finding the optimal method for balancing economic and environmental aspects, the social aspect is still omitted. In addressing this shortcoming, this study attempts to design a hybrid metaheuristic algorithm to balance economic performance with social expectations by matching the employees’ characteristics with those of a job shop. This study contributes to (1) confirming the importance of considering the social aspect for strengthening the theoretical basis; (2) proposing a hybrid metaheuristic algorithm in matching employees’ characteristics with the job shop; and (3) utilizing the optimal scenario leads the related firms in practicing sustainable production. The findings indicate that matching the employee-job-shop can fulfill the social expectation for generating positive effects on economic performance. If manufacturers insist on lowering labor costs, it may have a negative impact on production efficiency. Graphical Abstract
可持续生产旨在指导制造商实现可持续发展目标。尽管先前的研究已经开发了多种元启发式算法来寻找平衡经济和环境方面的最佳方法,但社会方面仍然被省略。为了解决这一缺点,本研究试图设计一种混合元启发式算法,通过将员工的特征与就业商店的特征相匹配,来平衡经济绩效与社会期望。本研究有助于(1)确认考虑社会方面对于加强理论基础的重要性;(2) 提出了一种混合元启发式算法,用于将员工的特征与车间进行匹配;(3)利用最优情景引导相关企业实施可持续生产。研究结果表明,匹配员工工作场所可以满足对经济绩效产生积极影响的社会期望。如果制造商坚持降低劳动力成本,可能会对生产效率产生负面影响。图形摘要

A genetic-simulated annealing algorithm is proposed, in which a simulated annealing procedure is constructed to re-optimize the optimal individual obtained by geneticthe genetic algorithm. Experiment results validate the effectiveness of proposedthe proposed seru scheduling model and genetic-simulated annealing algorithm for solving large-scale cases, and indicate that the stochastic processing time has a great influence on the makespan whichmakespan that can help production manager to makeproduce more consistent results according to the actual situation.

ABSTRACT The integration of circular economy (CE) models into everyday contexts generates huge amount of data involved in goods tracking and tokenization procedures. The sector of blockchain platforms is extremely varied, and the choice of the proper technology is not easy. It is important that the selection is conducted consistently with respect to the CE models. With this study, we present a performance index named Blockchain Circular Economy Index (BCEI). BCEI, obtained through Multicriteria Decision Analysis and Analytic Hierarchy Process, aims to measure the suitability of blockchain platforms to the needs highlighted by a CE scenario. The present study is contextualized by comparing six blockchain platforms, for each of which, the related BCEI is calculated. The results of the analysis show that transaction fee and energy consumption are the two most critical parameters. In addition, the results show the lack of a leading blockchain technology in CE models. Thus, there is a market space that can be exploited given the growing interest in digital and sustainable issues. Graphical abstract
摘要循环经济(CE)模型与日常环境的结合产生了大量涉及商品跟踪和标记化过程的数据。区块链平台的行业千差万别,选择合适的技术并不容易。重要的是,选择要与CE模型保持一致。通过这项研究,我们提出了一个名为区块链循环经济指数(BCEI)的绩效指标。BCEI通过多准则决策分析和层次分析法获得,旨在衡量区块链平台是否适合CE场景所强调的需求。本研究通过比较六个区块链平台来进行背景分析,并计算出每个平台的相关BCEI。分析结果表明,交易费用和能耗是两个最关键的参数。此外,研究结果表明,CE模型中缺乏领先的区块链技术。因此,鉴于人们对数字和可持续问题的兴趣日益增长,有一个可以利用的市场空间。图形摘要

ABSTRACT Unexpected crises such as the COVID-19 pandemic considerably influence business operations and supply chains worldwide. Therefore, many companies have adopted digitalization to address the rapidly changing environment.

摘要新冠肺炎疫情等突发危机对全球商业运营和供应链产生了重大影响。因此,许多公司都采用了数字化来应对快速变化的环境。然而,很少有研究探讨数字化与协同规划之间的中介机制。基于结构方程模型,本研究考察了数字化转型如何通过管理参与和信息共享的中介作用来改善协同规划。结果表明,数字化转型显著影响管理和信息共享。此外,管理层的参与和信息共享对协作规划产生了积极影响。然而,这项研究表明,数字化转型不会直接影响协同规划。总体而言,由于缺乏探索数字化转型和协同规划之间中介机制的研究,本研究有助于数字化和制造业,并提供了有价值的建议。从根本上讲,想要发展数字化并鼓励协同规划的公司应该考虑管理层参与和信息共享的影响。

ABSTRACT There is a large increase in the wastes and emissions from the Indonesian fashion industry under economic and population growth. To address this issue, the sustainable circular economy is proposed to reach the goal of sustainable development and zero waste. Previous studies neglect to provide a specific interrelationship model to guide practice to reach a sustainable circular economy. This study proposes a hybrid method integrating exploratory factor analysis, the fuzzy synthetic method and the decision-making trial and evaluation laboratory approach to overcome these shortcomings. It contributes to enhancing the understanding of theory through visual diagrams. The hybrid method makes it possible to interpret complex interrelationships and leads to improvements under resource limitations based on the model. The results reveal that emission reduction and welfare improvement are the causal aspects. Graphic Abstract
摘要随着经济和人口的增长,印尼时装业的废物和排放量大幅增加。为了解决这一问题,提出了可持续循环经济,以实现可持续发展和零浪费的目标。以往的研究忽略了提供一个具体的相互关系模型来指导实践,以实现可持续的循环经济。为了克服这些不足,本研究提出了一种将探索性因素分析、模糊综合方法和决策试验与评价实验室方法相结合的混合方法。它有助于通过可视化图表来增强对理论的理解。混合方法可以解释复杂的相互关系,并在资源限制的情况下基于模型进行改进。研究结果表明,减排和福利改善是造成这一现象的原因。图形摘要
