The integration of the built-in reliability (BIR) approach with reliability efforts from the design phase to the usage stage is crucial for ensuring the reliability of finished products. As an important carrier of product reliability, reliability-oriented key quality characteristics (R-KQCs) are present in all activities of the product life and are the core of BIR methods. Therefore, to improve the accuracy of identified R-KQCs from the big data of quality and reliability, a novel R-KQC intelligent identification method is proposed by adopting the simulated annealing-Harris hawk optimization (SA-HHO). First, the connotation of the BIR and R-KQC formation mechanism are introduced. Second, considering the large amounts of quality and reliability data, an identification method of R-KQCs is proposed based on the fuzzy PFMEA (Process Failure Mode and Effects Analysis) and SA-HHO algorithm. Third, on the basis of R-KQC identification, the assurance method of R-KQCs is proposed for proactive optimization of parameters and control of the process. Finally, an example of the shielding component reliability assurance is provided to verify the validity of the proposed method.

In response to the U.S. chip embargo, China has proposed export controls on crucial materials like gallium, germanium, and graphite. However, few studies have explored the economic impacts of these trade sanctions policies. This study aims to address this gap by examining theoretical mechanisms and constructing a global input–output database for the chip, gallium-germanium, and graphite sectors. Using a dynamic computable general equilibrium model, we evaluate the dynamic economic impacts of Sino–U.S. technological competition and conduct robustness tests. The results show that in the initial stage of policy implementation, under the most extreme situation of chip embargo, the GDP of China, U.S., and the world decreases by 1.051%, 0.006%, and 0.201%, respectively; that of Japan, South Korea, and Chinese Taiwan, which follow the U.S. in implementing chip sanctions, decreases by 0.109%, 0.177%, and 0.330%, respectively. China’s export controls on crucial raw materials are shown to reduce national economic damage and have a large negative impact on Japan, South Korea, and Chinese Taiwan. Moreover, these negative impacts tend to worsen over time. Our findings reveal that Sino–U.S. technological competition is unfavorable to the economic interests of the two countries and poses challenges to global economic recovery in the post-pandemic era, indicating the importance of narrowing the gap and reducing the confrontation between China and the U.S. for global economic growth.

Second-hand shopping, primarily via online marketplaces, has rapidly increased during the last decade. Nowadays, consumers widely choose the Pick-Up Point (PUP) service to facilitate the delivery of products. Parcels related to this Customer-to-Customer (C2C) activity are dropped off in PUPs chosen by the sellers, shipped to PUPs selected by the buyers where they wait to be picked up. The increased impact of C2C parcels on PUPs requires an improved control of their load to reduce the risks of PUP overload, parcel rerouting, and resulting customer dissatisfaction.
This paper presents a forecasting approach for the load of PUPs receiving C2C parcels. The daily number of parcels dropped off with a given PUP as target is described by a Markov-Switching Auto-Regressive (MSAR) model to account for the non-stationarity of the second-hand shopping activity. A PUP Management Company, using this forecasting approach, is able to propose customers only target PUPs that are likely not to be overloaded at time of delivery. The proposed approach is compared to load prediction techniques involving SARIMA, Holt–Winters, LSTM, Prophet, and TiDE models. For the considered PUP, the load is predicted from one up to seven days ahead with mean absolute errors ranging from 5.5 parcels (1 day ahead) to 8.8 parcels (7 days ahead) for a PUP with an average load of 25 parcels. Similar results are shown for other PUPs.

Geographical Indications (GIs) are increasingly prominent in the global economy, offering market leverage and propelling agricultural development. However, concerns arise that GI producers prioritize short-term gains over long-term quality assurance, leading to moral hazards and quality degradation. The prevalence of free-riding behavior within GI supply chains poses a collective action dilemma, significantly challenging the management of product quality.
In this paper, we explore the integration of blockchain technology and quality inspections into GI supply chains as potential solutions for establishing reliable and effective quality management measures. We develop a two-tier model involving one retailer and two farmers to analyze the effects of quality inspection and blockchain-based traceability on product quality and the handling of substandard products. By assessing the optimal profits of retailers and farmers under various quality management models, we ascertain the strategy that achieves a Pareto-efficient improvements.
Our research investigates the efficacy of blockchain-facilitated traceability and pre-sale inspection in shaping supply chain contracts, influencing quality decisions, and augmenting the overall value addition of blockchain integration. Despite the effectiveness of quality inspections in defect prevention, they fail to bolster overall earnings when implemented in isolation. Although the synergistic application of inspection and traceability substantially boosts GI supply chain profitability, our findings reveal that it does not increase farmers’ income. Interestingly, farmers are unlikely to prefer a singular reliance on quality inspection. Nevertheless, under specific market conditions, the adoption of blockchain presents a mutually beneficial scenario for both farmers and retailers. Based on these insights, we provide theoretical and practical guidance for optimizing quality management strategies in GI supply chains.

Efficient production processes are crucial in satisfying customer requirements and achieving operational superiority. This implies synchronisation between links in a supply chain to adapt to dynamic market needs. Due to its complexity, flexible flow shop scheduling has attracted much concern from academics and practitioners. In addition, sustainability issues have gained attention since efficient energy management enhances economic competitiveness and ecological responsibility. However, research often integrates flexible flow shop scheduling with distribution, leaving aside other stages, such as finished product packaging. Therefore, this paper proposes a model to optimise scheduling and package sizing considering multiple products and package sizes to minimise the cost of lost units and carbon dioxide emissions. A genetic algorithm was developed to find high-quality solutions based on minimising the Mean Ideal Distance. An experimental design was conducted to determine the parameters influencing the algorithm’s performance. The results emphasised the impact of the crossover rate, mutation rate, and number of generations. Also, sensitivity analyses were performed to explore the relationship between the package types, inventory and lost units. Results highlighted the advantage of diverse package sizes in aligning dispatched final products with demand. Furthermore, a relation between inventory and lost units across demand levels was observed, underscoring the impact of overscheduling in production systems.

This study builds upon our earlier research (Razm et al., 2023). This study makes several contributions. First, we define three weather criteria (Rainfall, Temperature, Daylight hours) to incorporate weather conditions into the optimization model. We gather real weather data and conduct data preprocessing. Next, numerous calculations are performed based on the criteria to determine biomass availability ranges. Second, we immunize our system against uncertainties; however, uncertain parameters in our model possess specific features. Uncertainties exist both in the rows and columns. The traditional method cannot effectively address this issue. Therefore, we propose a row and column-wise robust optimization model to tackle weather and price uncertainties. Third, incorporating the aforementioned contributions into our previous model presents challenges. The new model is complex. Analyzing its behavior and interpreting results are challenging for this study. However, we conduct a series of numerical experiments and extract valuable managerial insights. Results show that despite incurring extra costs initially, the manager stands to gain more profit in the future, attribute to the system’s robustness. Finally, we enhance our model and increase system profitability by adopting data-driven robust optimization based on Machine Learning.

The synergy between production rescheduling and machine maintenance is critical, particularly in cases where unforeseen equipment failures, not fully prevented by maintenance, might threaten the viability of the original plan. In this context, this paper explores a novel integrated optimization problem of production rescheduling and preventive maintenance in a capacity-limited flexible flow-shop (CLFFS), in which random equipment failures, hybrid rigid–flexible constraints of buffer capacity and due window are considered. Specifically, (1) an integrated optimization model is established to minimize the makespan, average flow time, earlinesstardiness penalty, machine workload extreme deviation and system instability; (2) an adaptive hybrid rescheduling strategy (AHRS) that amalgamates three classical rescheduling approaches is designed to effectively respond to random equipment failures; and (3) an improved bi-population cooperative evolutionary algorithm with an adaptive environment selection mechanism (AES-IBCEA) is developed to deal with the integrated problem. In the numerical experiments, Taguchi method is first employed to set the parameters of the proposed algorithm. Second, the effectiveness and superiority of designed operators and proposed AES-IBCEA are validated through algorithm comparison. Next, the competitiveness of the proposed AHRS is demonstrated by contrasting it with other rescheduling strategies, and the average improvement rate is up to 22.12%. Finally, a sensitivity analysis on the fault impact threshold () and the individual selection threshold () is performed, and the results reveal that has a significant impact on the algorithm’s performance.

Effective supervision and the prevention of concealment and false reporting in dangerous supply chain goods require collaboration among multiple departments. Because of its decentralized consensus mechanism, blockchain has potential as an efficient tool for the collaborative supervision of dangerous goods supply chains. In this study, a blockchain-based conceptual platform was proposed for the supervision of dangerous goods supply chains. It features multiple layers, namely, blockchain, storage, interaction, and interface, each fulfilling distinct roles to ensure a comprehensive and efficient system. To enable efficient on-chain data sharing of diverse types of data, three modes of on-chain data integration leveraging IPFS (InterPlanetary File System) and FISCO BCOS were implemented. Additionally, a traceable state machine was proposed, which uses smart contracts to facilitate the traceability of the supervision process. The feasibility of the conceptual platform was validated through the deployment of a prototype platform with eight blockchain nodes. The results indicate that the platform has a latency of 500–550 ms and approximately 2 TPS (Transactions Per Second) to complete data sharing. It also has a latency of less than 3 s and more than 1 TPS when carrying out complex supervision process tracing. The proposed conceptual platform has the ability to address data silo issues in the dangerous goods supply chain. Moreover, the traceability of the supervision process enhances the accurate tracing of accident liabilities.

This paper studies the joint optimization of storage location assignment and order batching in robotic mobile fulfillment systems (RMFS), considering dynamic storage depth and surplus items. Firstly, a joint optimization model of storage location assignment and order batching is established. The model is divided into two stages. The first stage is the item location assignment optimization model, which is used to describe the types and quantities of items placed in each slot on each pod. The second stage is the joint optimization model of pod location assignment and order batching, which is used to describe the coordinates of each pod, the number of order batches, and the order combinations contained in each batch. Considering the vast solution space and the numerous constraints of the constructed model, a two-stage greedy variable neighborhood simulated annealing algorithm (TGVNSA) is introduced to address these challenges. Finally, numerical experiments prove that the algorithm can effectively solve the established model. TGVNSA is evaluated against two conventional methods: variable neighborhood search and adaptive genetic algorithms, focusing on metrics such as pod retrieval times, comprehensive picking costs, CPU time, and CQ value (comprehensive quality in the item location assignment). The findings demonstrate that TGVNSA boasts superior comprehensive performance. Compared with other commonly used strategies in the field such as random, classification, and optimal relevance, the method proposed in this paper demonstrates superior optimization performance, particularly when considering dynamic storage depth and surplus items. Moreover, this paper also proves that, under the same combination of strategies, the joint optimization method proposed in this paper reduces the comprehensive picking costs by 11.46% compared to the separate optimization approach.
本文研究了机器人移动履约系统(RMFS)中存储位置分配和订单分批的联合优化,并考虑了动态存储深度和剩余物品。首先,建立了存储位置分配和订单批量的联合优化模型。该模型分为两个阶段。第一阶段是物品位置分配优化模型,用于描述放置在每个 pod 上每个插槽中的物品类型和数量。第二阶段是吊舱位置分配和订单批次的联合优化模型,用于描述每个吊舱的坐标、订单批次的数量以及每个批次所包含的订单组合。考虑到所建模型的求解空间巨大、约束条件繁多,引入了两阶段贪婪可变邻域模拟退火算法(TGVNSA)来解决这些难题。最后,数值实验证明该算法能有效地解决所建立的模型。针对两种传统方法:可变邻域搜索和自适应遗传算法,对 TGVNSA 进行了评估,重点关注 pod 检索时间、综合拣选成本、CPU 时间和 CQ 值(物品位置分配的综合质量)等指标。研究结果表明,TGVNSA 具有卓越的综合性能。与该领域其他常用策略(如随机、分类和最佳相关性)相比,本文提出的方法表现出更优越的优化性能,特别是在考虑动态存储深度和剩余物品时。此外,本文还证明,在相同的策略组合下,本文提出的联合优化方法比单独优化方法降低了 11.46% 的综合拣选成本。

Firstly, a joint optimization model of storage location assignment and order batching is established. The model is divided into two stages. The first stage is the item location assignment optimization model, which is used to describe the types and quantities of items placed in each slot on each pod. The second stage is the joint optimization model of pod location assignment and order batching, which is used to describe the coordinates of each pod, the number of order batches, and the order combinations contained in each batch. Considering the vast solution space and the numerous constraints of the constructed model, a two-stage greedy variable neighborhood simulated annealing algorithm (TGVNSA) is introduced to address these challenges. Finally, numerical experiments prove that the algorithm can effectively solve the established model. TGVNSA is evaluated against two conventional methods: variable neighborhood search and adaptive genetic algorithms, focusing on metrics such as pod retrieval times, comprehensive picking costs, CPU time, and <em>CQ</em> value (comprehensive quality in the item location assignment). The findings demonstrate that TGVNSA boasts superior comprehensive performance.

In the context of the Industry 5.0 vision, which emphasises the importance of human-centred industries, assembly lines wherein humans and robots work together have emerged as innovative systems that allow the advantages of both to be combined. Accordingly, industrial managers are attempting to implement collaborative systems that will benefit from the consistency of robots and their capacity to work in hazardous environments, as well as the insight and adaptability of humans. Nevertheless, the process of eliminating an existing system and building another one from scratch is both costly and time-consuming. Rather than constructing an entirely new system, it is possible to reconfigure the line based on the new situation, thus enabling the system to adapt to changes. To the best of our knowledge, studies in the literature on collaborative assembly lines have focused on the initial installation phase, while the researchers who have dealt with the rebalancing process have not taken into account the change in the workforce structure as a reason for rebalancing. This study introduces the Assembly Line Rebalancing Problem with Human-Robot Collaboration as a means of filling the perceived gap in the literature. The considered problem addresses the need for line rebalancing to integrate traditional and collaborative robots as operators in existing manual assembly lines. In order to tackle this problem, a mathematical modelling approach and an artificial bee colony algorithm-based hyper-matheuristic algorithm are presented with the objective of optimising cycle time. The results of the computational tests on benchmark problems adapted from the literature demonstrate that the proposed algorithm outperforms the mathematical modelling approach and basic artificial bee colony algorithm.
