In this article, we focus on developing a blood supply chain based on blockchain technology using a simulation–optimization approach that integrates optimization techniques into simulation modeling and analysis for the first time. In the system dynamics approach, by examining factors, such as service quality, and social aspects that impact donors’ behavior, the main decisions, including the total amount of platelets that are distributed to all hospitals and the number of donors, are simulated under blockchain technology. Various policies are explored to evaluate their effect on the blood supply and demand. Then, this study introduces a biobjective mathematical model utilizing data envelopment analysis (DEA) to optimize the fair distribution of platelets to hospitals based on their efficiency. The outputs of the dynamics model (total platelets distributed to hospitals) and the DEA model (efficiency of selected hospitals) are entered into the biobjective model as parameters. The integration of blockchain technology allows managers to improve traceability at every stage, and the system with blockchain technology increases donor participation by 6%, 3%, and 12%.","PeriodicalId":55009,"journal":{"name":"IEEE Transactions on Engineering Management","volume":"72 ","pages":"591-603"},"PeriodicalIF":4.6,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study addresses this gap by analyzing public beliefs about GenAI using the Technology Acceptance Model and Diffusion of Innovations Theory as frameworks. We adopted a big-data approach, utilizing machine-learning techniques to analyze 21,817 public comments extracted from an initial set of 32,707 on 44 YouTube videos discussing GenAI. Our investigation surfaced six pivotal themes: concerns over job and economic impacts, GenAI's potential to revolutionize problem-solving, its perceived shortcomings in creativity and emotional intelligence, the proliferation of misinformation, existential risks, and privacy decay. Emotion analysis showed that negative emotions dominated at 58.46%, including anger (22.85%) and disgust (17.26%). Sentiment analysis echoed this negativity, with 70% negative. The triangulation of thematic, emotional, and sentiment analyses highlighted a polarized public stance: recognition of GenAI's transformative potential is tempered by significant concerns about its implications. The findings offer actionable insights for engineering managers and policymakers. Strategies such as awareness-building, transparency, public engagement, balanced communication, governance, and human-centered development can address polarization and build trust. Ongoing research into public opinion remains essential for aligning technological advancements with societal expectations and acceptance.","PeriodicalId":55009,"journal":{"name":"IEEE Transactions on Engineering Management","volume":"72 ","pages":"827-841"},"PeriodicalIF":4.6,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In response, platforms in such markets compete aggressively through high subsidies for market dominance, leveraging network effects to achieve success. We examine such aggressive subsidy wars between new competitors and dominant incumbents, where the one that first runs out of funds risks market expulsion or marginalization. Our analysis incorporates consumer heterogeneity in network effects to evaluate subsidy strategies from a cost-effectiveness perspective. That is digital platforms, whether serve as suppliers or channels in platform-based supply chains, optimize either per acquisition cost or total subsidy expenditure. Our findings reveal that it is optimal for the dominant platform to protect its market dominance when the competitor's market share reaches a certain level, varying in distinct competitive contexts. Specifically, for channel platforms connecting buyers and suppliers, subsidy allocation must be balanced between user groups. We find that new competitors should typically subsidize the side with lower market share, while dominant platforms maintain equal market shares on both sides by adjusting subsidies in most cases. Interestingly, our findings demonstrate that a dominator's larger market shares cannot guarantee its competitive advantage in subsidy wars, which is influenced by the factors such as cost structure, competitor's financial capabilities, network effect strength, and product differentiation. We also identify critical conditions for new competitors to successfully win market dominance through initiating subsidy wars, while offering strategic guidance for dominant incumbents to defend their positions.","PeriodicalId":55009,"journal":{"name":"IEEE Transactions on Engineering Management","volume":"72 ","pages":"689-702"},"PeriodicalIF":4.6,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the key influencing factors, underlying mechanisms, and theoretical models of consumer complaints have not been fully explored. Therefore, we innovatively propose a two-staged SEM-ANN technique to identify key influencing factors and explore their nonlinear relationships. Through experimental analysis of the collected data, we have found several interesting conclusions. The results show that consumer confusion positively influences the venting negative emotional motives and produces negative attitudes, and consumer confusion positively influences altruistic motives. Group complaints positively influence the venting negative emotional motives and altruistic motives. At the same time, it has been confirmed that altruistic motives have significant mediating effects. The findings contribute to the literature and guide to help managers, participants, and policymakers establish effective and innovative operational management measures.","PeriodicalId":55009,"journal":{"name":"IEEE Transactions on Engineering Management","volume":"72 ","pages":"1027-1038"},"PeriodicalIF":4.6,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143740236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Industry 4.0 currently involves the integration of new technologies, digitalization, and the massive use of data in manufacturing processes. This represents a paradigm shift in quality management. However, the meaning and fundamentals of quality 4.0 (Q4.0) are still debated in the literature. In this article, the main objective is to identify the key dimensions and implementation profiles of Q4.0 in Spanish industrial and service organizations with excellence recognition systems. Different multivariate analysis techniques, such as cluster analysis, contingency tables, and one-factor analysis of variance, are used as a methodology. The results identify three profiles of organizations (advanced, in-development, and early stage) that apply the nine critical dimensions of Q4.0 identified with varying intensity. In addition, customer engagement, human resource management for Q4.0, and data for decision support are the dimensions that most help differentiate these organizations. Finally, differences were found in the degree of Q4.0 implementation according to size, sector, and the degree of excellence achieved by the organization.","PeriodicalId":55009,"journal":{"name":"IEEE Transactions on Engineering Management","volume":"72 ","pages":"527-545"},"PeriodicalIF":4.6,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143361074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study, grounded in self-enhancement theory and behavioral research, proposed a research model on how firm innovation is affected by performance surplus inconsistency, which refers to discrepancies in historical and social performance surpluses. Using panel data from 1415 publicly listed Chinese manufacturing companies spanning 2007 to 2019, we applied polynomial regression and response surface analysis to test our research model. Polynomial regression allowed us to examine how multiple independent variables simultaneously influence the outcome, while response surface analysis used the regression coefficients to further evaluate and visually represent how inconsistent combinations of these variables impact the outcome. Our findings reveal that performance surplus inconsistency positively influences research and development (R&D) intensity. Firms that exhibit a combination of low historical performance surplus and high social performance surplus demonstrate higher levels of R&D intensity compared with those with the reverse combination (high historical performance surplus and low social performance surplus). We also find that government subsidies enhance the positive effect of performance surplus inconsistency on R&D intensity. By emphasizing the role of performance surplus inconsistency in driving firm innovation, this study offers a multireference perspective to explore innovation in high-performing firms. It contributes to ongoing discussions on performance surplus and firm innovation, offering valuable insights for managers and policymakers to promote innovation.","PeriodicalId":55009,"journal":{"name":"IEEE Transactions on Engineering Management","volume":"72 ","pages":"512-526"},"PeriodicalIF":4.6,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143361073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A survey with 216 practitioners from different Australian companies was conducted, assessing their level of LP implementation, resilience development, and operational performance. We framed our investigation using concepts from the resource-based view theory. Findings indicate that the development of resilience abilities positively mediates the relationship between certain LP practices and operational performance in the face of a disruptive event, such as the COVID-19 pandemic. Nevertheless, the internally related LP practices involved in such mediation may differ according to the purpose of the resilience abilities developed by companies, i.e., anticipate/monitor or adapt/restore. Due to the disruptions resulting from the COVID-19 pandemic, the development of resilience in organizations and supply chains has increased in relevance. In theory, some strategies to enhance resilience (e.g., increase slack resources) might conflict with LP practices and principles. The scarcity of empirical evidence raises questions about the generalizability of existing indications, and the lack of consensus on the relationship between LP implementation and organizational resilience development constitutes a relevant research gap. The manufacturing industry is an important sector of the Australian economy. However, during the COVID-19 pandemic, the Australian government has imposed severe social distancing measures and business restrictions, with direct implications for the manufacturing capacity. Thus, understanding how the development of LP-based organizational resilience could contribute to better operational performance in this sector during severe disruptive events becomes fundamental to better preparing for future occurrences.","PeriodicalId":55009,"journal":{"name":"IEEE Transactions on Engineering Management","volume":"72 ","pages":"800-814"},"PeriodicalIF":4.6,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite this interest, the literature on the economic impacts of interdisciplinary technology remains limited. This study aims to investigate the relationship between interdisciplinary university technology and its potential for commercial success. Drawing on the knowledge recombination view, our study proposes that the technology readiness level (TRL) and high coordination costs are two underlying factors that hinder the commercialization—indicated by patent licensing and reassignment to firms—of interdisciplinary university technology. On the basis of learning theory, we propose that three factors, namely, the inventor's industrial experience, university–industry engagement, and experiential learning over time, mitigate the challenges associated with a low TRL and high university–industry coordination costs, thereby increasing the propensity for commercializing interdisciplinary technology. To test our arguments, we employ a topic modeling method on 287 616 Chinese university patents to construct a topical diversity index for each patent, which measures each patent's level of interdisciplinarity. The regression analysis reveals that, for our novel definitions of patent topical diversity and the TRL introduced in this work, topical diversity is negatively associated with the TRL and, ultimately, the commercialization rate. Furthermore, inventor industrial experience, university–industry engagement, and time positively moderate the relationship between interdisciplinary technology and commercialization. Our research has important theoretical and practical implications for interdisciplinarity and technology commercialization.","PeriodicalId":55009,"journal":{"name":"IEEE Transactions on Engineering Management","volume":"72 ","pages":"471-490"},"PeriodicalIF":4.6,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143105743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, what factors can impact firms’ usage of A/B testing in their digital product development becomes an important question that merits a deep investigation. To address this issue, in this article, we leverage a technology–organization–environment framework to investigate the specific technological, organizational, and environmental factors that can facilitate or hinder firms’ usage of A/B testing. We also explore the mediation paths among these factors and the boundary conditions for these relationships. Based on our analyses of a sample of 555 firms in China, we find support for most of our hypotheses.
