ABSTRACT Train formation planning (TFP) is essential for rail freight logistics services. The fluctuation of railcar flows dramatically compared with before the outbreak of COVID-19. This paper studies train formation planning, considering three types of train services provided for railcar flow between pairs of technical stations (TS), including direct trains, district trains, and pickup trains. This paper introduces an optimization model with average railcars flow data (OMAD) and an optimization model with dynamic railcars flow data (OMDD) for the train formation planning based on TS under railcar demand fluctuation while minimizing railcar-hour consumption. The OMAD is a deterministic model, and the OMDD is a probability constraint model. To solve the OMDD, an approach for transforming probability constraints into deterministic constraints is presented. Various groups of scenarios are given to verify the effectiveness of the proposed models. Graphical abstract
列车编组计划(TFP)是铁路货运物流服务的重要组成部分。与新冠肺炎爆发前相比,轨道车流量的波动显著。本文研究了列车编组规划,考虑了为技术站对之间的轨道车流动提供的三种列车服务,包括直达列车、区间车和皮卡列车。本文介绍了一种基于TS的列车编组规划的平均轨道车流量数据优化模型(OMAD)和动态轨道车流量数据库优化模型(OMDD),用于在轨道车需求波动的情况下,最小化轨道车小时消耗。OMAD是一个确定性模型,而OMDD是一个概率约束模型。为了解决OMDD问题,提出了一种将概率约束转化为确定性约束的方法。给出了不同的场景组来验证所提出的模型的有效性。图形摘要

ABSTRACT There is a growing concern over environmental pollution resulting from the production. Moreover, the expansion of various industries has led to an increased demand for raw materials. To address these challenges, this paper aims to investigate the bi-objective optimization of a sustainable reverse supply chain network while considering two key sources of uncertainty in the returned product quality and the remanufacturing capacity. Additionally, the study considers the effects of carbon tax policies and government subsidies on remanufactured products, while also focusing on three important sustainability aspects - economic, social, and environmental. The study uses two quality thresholds at inspection centers to sort products, and the epsilon constraint and NSGA-II are applied to solve the model. Through numerical analysis, the research demonstrates that objective functions are sensitive to uncertain parameters and minimum acceptable quality levels. Furthermore, the study reveals that government subsidies can offset the negative effects of carbon tax policies. Graphical abstract
由于生产而造成的环境污染越来越受到人们的关注。此外,各种工业的扩张导致对原材料的需求增加。为了应对这些挑战,本文旨在研究可持续逆向供应链网络的双目标优化,同时考虑退货质量和再制造能力这两个关键的不确定性来源。此外,该研究还考虑了碳税政策和政府补贴对再制造产品的影响,同时也关注了三个重要的可持续性方面——经济、社会和环境。本研究采用检验中心的两个质量阈值对产品进行分类,并应用epsilon约束和NSGA-II对模型进行求解。通过数值分析,研究表明目标函数对不确定参数和最小可接受质量水平敏感。此外,研究表明,政府补贴可以抵消碳税政策的负面影响。图形抽象

ABSTRACT Accurate price prediction for carbon trading is essential to provide the guidance for investment and production. The current prediction methods mainly depend on the carbon price itself, from which the change pattern of carbon price is studied. However, fusing the multi-source data, e.g. trading message and public sentiment, and taking proper data processing to improve the prediction accuracy need in-depth research. In this paper, a hybrid price prediction method utilizing both the statistical and intelligent models is established on multi-source data, and the data characteristics are fully explored by correlation analysis and multi-frequency analysis. The study on Guangdong market show that: the accuracy of proposed method is superior to the benchmark ones: root mean square error and mean absolute percentage error are reduced by 19.27% and 7.16%, while determination coefficient and trading return are increased by 8.31% and 25.11%. The proposed method is helpful for stakeholders to manage their trading. Graphical abstract

ABSTRACT The COVID-19 outbreak has posed significant challenges to the worldwide supply chain. As result, there is an urgent need to develop a model for the manufacturer that includes multi-phase manufacturing with fluctuating demand during various levels of pandemic and a supply system that takes into account the environmental benefits of the product and production. This study recommends inventory model to the company for estimating optimal production amount and replenishment cycle in order to reduce overall cost and maximize profit along with green product pricing and carbon tax. The current study considers models with and without shortages for instantaneously deteriorating commodities. Because of the social awareness concern, firms can avoid the suffering from labor shortage during the pandemic crisis. Numerical examples are given to demonstrate the model’s use. A sensitivity analysis of crucial factors was performed in order to uncover more sensitive parameters that offer a clear portrayal of current concerns.

ABSTRACT This study addresses the optimization of price and production quantity using game theory in the coffee supply chain in the city of Isfahan. The presented model focuses on the competition among members of the chain in a probabilistic environment and is based on discrete selection models. This model examines the impact of inventory and routing costs on the pricing model at the same time. To effectively solve real-world problems, the method of normal distribution approximation is used instead of the binomial distribution. The results of the model indicate that the computational time of the applied approximate model does not change with increasing the number of customers, and the model can determine the optimal price and production quantity. The advantage of the proposed model over other classic models is that it considers the inventory costs that have not yet been considered in price competition models with discrete selection.

摘要本研究采用博弈论方法对伊斯法罕市咖啡供应链中的价格和产量进行优化。所提出的模型专注于概率环境中链成员之间的竞争,并基于离散选择模型。该模型同时考察了库存成本和路线成本对定价模型的影响。为了有效地解决实际问题,使用了正态分布近似方法来代替二项式分布。该模型的结果表明,所应用的近似模型的计算时间不会随着客户数量的增加而变化,并且该模型可以确定最优价格和生产数量。与其他经典模型相比,所提出的模型的优势在于,它考虑了离散选择的价格竞争模型中尚未考虑的库存成本。图形摘要

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。

A hierarchical heuristic algorithm for multi-objective order allocation problem subject to supply uncertainties 考虑供给不确定性的多目标订单分配问题的层次启发式算法
IF 4.5 Q2 Engineering Pub Date : 2023-04-11 DOI: 10.1080/21681015.2023.2200611

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.

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

Pre-defined policies are first implemented to generate the initial order allocation to suppliers.

The fine-tuning process finally reduces the gap between the two consecutive order allocation schemes.

ABSTRACT This study contributes to the complex adaptive system theory by offering a valid hierarchical model to evaluate the theory’s important features related to resilience. The garment industry in Bangladesh encountered disruption in the supply chain during the COVID-19 pandemic and the supply chain competencies played a vital role in overcoming the crisis. Limited studies are built on a solid theoretical foundation and considered supply chain competencies in assessing supply chain resilience. This study aims to develop a multi-criteria hierarchical measurement structure by considering the supply chain competencies to evaluate supply chain resilience. Fuzzy Delphi method and Fuzzy importance and performance analysis approach were applied for the study purpose. Findings reveal health and safety management, information management system, business intelligence, innovation capabilities management, technological innovation, and artificial intelligence as critical criteria, and data, information, and computing, technological innovation and adaptation are critical aspects that require improvement.
