The bike rebalancing problem is one of the main challenges in bike-sharing systems. In this paper, we propose a framework to address the dynamic bike rebalancing problem in dockless bike-sharing systems by using trucks to relocate bikes to meet the time-varying demand at each location. We decompose the problem into two processes: dynamic clustering and bike relocation. For dynamic clustering, we propose an optimisation model to select cluster centroids and decide the number and coverage of clusters to maximise operational profit based on trip revenues and expected traversal costs between clusters. An Adaptive Large Neighbourhood Search (ALNS) algorithm is developed to solve this problem. Clusters with too many bikes would lead to bike piles and cause urban blight, while clusters with too few bikes may result in user dissatisfaction. To prevent such issues, in the bike relocation process, we construct vehicle routes with pickup and delivery for bike relocation between clusters. We test the framework using real data from Louisville, USA. We show that the proposed ALNS can efficiently solve large real-life instances and obtain high-quality solutions. Numerical experiments also indicate that the dynamic clustering model significantly increases average daily profit compared to static clustering benchmarks. We provide operators with several insights into the impact of clustering and relocation in bike-sharing systems.</div></div>","PeriodicalId":14287,"journal":{"name":"International Journal of Production Economics","volume":"285 ","pages":"Article 109634"},"PeriodicalIF":9.8,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143874091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study considers two predominant production line configuration strategies in a production environment characterized by multi-variety and small-batch orders: (1) a <em>double-line configuration strategy</em>, where a fully automated intelligent production line focuses on producing relatively standardized products, while a manual production line is dedicated to crafting personalized products. We obtain optimal work allocation under this strategy. (2) a <em>line-changeover configuration strategy</em>, characterized by a single flexible production line where machine-driven tasks are automatically executed. Manual intervention is only required during line changeovers and setups between different product types. A comparative cost analysis between these two configuration strategies reveals that, for production batch size exceeding a batch threshold, the line-changeover strategy outperforms the double-line strategy. Moreover, if a square root rule is satisfied, the line-changeover strategy consistently outperforms the double-line strategy. Notably, investments directed towards setup reduction prove instrumental in reducing production costs and reducing the batch threshold, thereby amplifying the advantages of the line-changeover strategy. The future comparative advantage of these two configuration strategies is contingent upon ongoing technological developments.</div></div>","PeriodicalId":14287,"journal":{"name":"International Journal of Production Economics","volume":"285 ","pages":"Article 109647"},"PeriodicalIF":9.8,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143860179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies utilize social media data and the Kano model to delineate opportunities for product quality enhancement. However, a favorable performance appraisal from customers does not guarantee that the product gains a competitive edge over its rivals. Performance evaluation may be inaccurate and biased without comparing the product to its competitors. Moreover, few studies research dynamic quality attributes and propose strategies for dynamic quality enhancement. In this study, we propose a dynamic approach to improving product quality using social media data. Firstly, we categorize social media data into texts with positive, negative, and neutral sentiments. By considering competitors, we then dynamically estimate product performance and customer satisfaction using these texts, Dynamic Topic Models, and sentiment analysis. Secondly, we cluster product features into diverse quality attributes using our proposed competitor-based Kano model. Finally, we use a case study of laptops for validation. Experimental results not only validate the lifecycle of quality attributes (changing from indifferent to attractive attributes, which turn to one-directional/must-be attributes) proposed by extant research, but also reveal new trajectories of quality attributes (fluctuating among one-directional, must-be, and attractive attributes). Additionally, the comparison with baseline methods manifests that our method provides manufacturers with timely decision support to improve product quality, formulate product development strategies, and enhance product competitiveness.</div></div>","PeriodicalId":14287,"journal":{"name":"International Journal of Production Economics","volume":"285 ","pages":"Article 109645"},"PeriodicalIF":9.8,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143854536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An overlooked aspect in the literature is how operational concessions—such as extended trade credit terms and excess inventory holding—naturally emerge as a way for suppliers to balance power asymmetries in relationships with major customers. These concessions act as equilibrium outcomes that sustain partnerships but burden suppliers. Addressing this gap, we explore how ES commitments from major customers shift this equilibrium, reducing the need for suppliers to offer long trade credit and hold excess inventory, thereby improving efficiency through a shorter operating cycle. Our results show that suppliers working with ES-committed customers achieve shorter operating cycles, driven by reductions in both inventory days and receivable days. Additionally, suppliers leverage ES performance to signal credibility, reducing their reliance on long credit terms as assurance. During the 2008 financial crisis and its aftermath, suppliers reciprocated the goodwill of ES-committed customers by offering longer credit terms, fostering resilience and mutual support within the supply chain during financial stress. These findings contribute to the literature on sustainable supply chain management by showing how ES commitments foster trust-based partnerships that enhance long-term supply chain resilience across both stable and crisis periods.</div></div>","PeriodicalId":14287,"journal":{"name":"International Journal of Production Economics","volume":"285 ","pages":"Article 109640"},"PeriodicalIF":9.8,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143854535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, topic modeling is employed to analyze existing PV research, identify mainstream topics, and outline the critical pathways for sustainable development. Second, focusing on a primary pathway, a two-stage decision-making model based on text mining is introduced to evaluate and optimize the target PV system. In the first stage, text mining is integrated with an adaptive multi-objective particle swarm optimization algorithm to generate Pareto solutions across three objectives: lifecycle cost, loss of power supply probability, and global warming potential of greenhouse gas emissions. In the second stage, stochastic multicriteria acceptability analysis is applied to select the optimal Pareto solution. The framework is validated through its application to a real-world case involving PV carport configuration in Chengdu, China. This study not only establishes an objective and comprehensive research paradigm for analyzing PV system sustainability through text analysis but also provides decision-making references for researchers and industry practitioners to better understand the development logic and pathways for sustainable PV system configuration.</div></div>","PeriodicalId":14287,"journal":{"name":"International Journal of Production Economics","volume":"285 ","pages":"Article 109610"},"PeriodicalIF":9.8,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143842916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Failure to do so will result in lost sales, which happens when stockouts occur at both echelons and there is no inventory in transit. The lead time at the central warehouse is a random variable following a general distribution. Empirical evidence suggests that the Compound Poisson Process provides a more accurate fit for the lumpy and intermittent demand of spare parts compared to the Poisson process, which is the approach often adopted in the literature. This paper follows a queueing network modeling approach to find the inventory performance measures in closed-form when the lead time at the central warehouse follows a general distribution.

This often leads to a lack of comprehensive understanding of demand distribution and can result in suboptimal order decisions. To address this issue, we introduce a data-driven newsvendor framework that combines a novel cost-driven data correction procedure with distributionally robust optimization (CDDC-DRO). With cost minimization objectives, the proposed procedure integrates local censored demand data and external demand information to adaptively generate high-value improved censored datasets, while circumventing reliance on static correlations. Furthermore, we consider the granularities of external demand information and propose three DRO-based data correction strategies to effectively reduce demand censoring. Tests on both simulated and actual data indicate that the CDDC-DRO procedure adaptively corrects censored data based on demand characteristics and cost structures, thereby eliminating significant errors induced by demand censoring and improving the precision and robustness of order decisions. The correction degree of the improved censored datasets dynamically depends on cost structure. A high degree of data correction is employed under high critical ratios, whereas a minimal correction degree is applied under low critical ratios. In response to the significant negative impacts of demand censoring, SMEs prefer to implement the DRO-based data correction strategy with finer-grained external demand information. This strategy enhances correction capabilities while minimizing variations in decision accuracy. Even when finer-grained external demand information is unavailable, SMEs are able to make well-informed order decisions using the DRO-based data correction strategy with local censored demand data.</div></div>","PeriodicalId":14287,"journal":{"name":"International Journal of Production Economics","volume":"285 ","pages":"Article 109626"},"PeriodicalIF":9.8,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143854534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
