Blockchain technology can enhance the transparency and credibility of information, making it a suitable solution for addressing such misrepresentation. To investigate the impacts of misrepresentation of carbon emissions and blockchain technology on the production process among competing manufacturers, we develop three supply chain models based on various blockchain adoption strategies and analyze the equilibrium decisions for each member, as well as the cost threshold for adopting blockchain technology. The results indicate that both manufacturers tend to moderately overstate carbon emissions to enhance profitability, but it ultimately impedes the long-term sustainable development of the supply chain. Furthermore, adopting blockchain technology can significantly enhance the profitability, consumer surplus, and social welfare of the supply chain. As more manufacturers adopt blockchain technology, these benefits are further amplified. However, the adoption of blockchain does not consistently lead to favorable outcomes. An increase in product demand will inevitably lead to a rise in total carbon emissions. Meanwhile, blockchain technology will only be adopted by manufacturers if its operational costs fall within a specific range, which is approximately 12% of their profit levels. Manufactures should collaborate with reputable and highly skilled blockchain companies, while governments should also provide appropriate subsidies to support manufacturers. Moreover, implementing cap-and-trade regulation and increasing the trading price of unit carbon emission permit can serve as incentives for manufacturers to invest in green technology aimed at reducing total carbon emissions.</div></div>","PeriodicalId":55220,"journal":{"name":"Computers & Industrial Engineering","volume":"203 ","pages":"Article 110960"},"PeriodicalIF":6.7,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143512386","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}

While traditional approaches to the resource-constrained project scheduling problem have primarily focused on single-site contexts, modern project environments often span multiple sites, necessitating the development of models that can accommodate this complexity. On the other hands, the growing importance of social sustainability in project planning underscores the need to address issues such as equitable workload distribution across project sites. This paper introduces a novel sustainable multiobjective multi-site resource-constrained project scheduling problem that integrates multi-site scheduling considerations with the principles of social sustainability. The problem formulation aims to minimize both project makespan and the deviation between maximum and minimum working loads across project sites. Additionally, three types of renewable, non-renewable, and doubly-constrained resources are simultaneously addressed in the problem for the first time to improve its realism. To solve this problem, an interactive fuzzy TH approach is proposed as an exact approach to handle the conflict between the objectives. In the second step, three well-known multiobjective metaheuristic algorithms, including NSGA-II, MOPSO, and SPEA-II, are designed and implemented to address the complexity of the problem in large-sized projects. An efficient repair algorithm is designed to ensure the feasibility of solutions and handle the problems’ constraints in the search procedure. Taguchi’s design of experiments is proposed to calibrate the input parameters of algorithms and improve their efficiency. Numerical examples from the literature are utilized to illustrate the efficacy of the proposed model and solution methodology. In this direction, the one-way analysis of variance and Kruskal–Wallis parametric and non-parametric statistical tests are also used to provide a more systematic comparison of results. In general, the results reveal the better performance of NSGA-II in terms of the quality of solutions, while SPEA-II outperforms in terms of CPU time. Finally, insights for project managers are discussed and the paper is concluded by suggesting some directions for future research.</div></div>","PeriodicalId":55220,"journal":{"name":"Computers & Industrial Engineering","volume":"203 ","pages":"Article 110968"},"PeriodicalIF":6.7,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143474814","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}

{"title":"Competition and cooperation between green and non-green supply chains under Government’s subsidy and carbon tax to consumers","authors":"Wenfang Shang ,&nbsp;Zaixin Han ,&nbsp;Wei Wei ,&nbsp;Tao Li","doi":"10.1016/j.cie.2025.110957","DOIUrl":"10.1016/j.cie.2025.110957","url":null,"abstract":"<div><div>Consumers don’t always opt for green products. The government thus needs to provide a subsidy for consumers purchasing green products and impose a carbon tax penalty on those purchasing non-green products so as to foster the growth of green supply chains (GSCs). However, discussions regarding the effects of such interventions must take into account the competitive and cooperation mode between green and non-green supply chains (NGSC). This paper aids in identifying which mode is more conducive to the government’s intervention playing a positive role. It proposes a novel model focusing on two independent competitive supply chains: a GSC and a NGSC. In practice, the standard of green products is often determined by government and industry competition, rather than decisions made by green manufacturers themselves. Therefore, this paper regards it as an exogenous variable and considers how consumers’ acceptance for green products influences on consumers’ own utility, market demand, and supply chain members’ profits in different competition and cooperation modes. Results show that higher green costs will drive up the wholesale and retail prices of both green and non-green products. Subsidy and carbon tax will increase the wholesale and retail prices of green products, while reducing those of non-green products. The improvement of green standards will inevitably lead to an increase in the wholesale and retail prices of green products, but its impact on the pricing of non-green products depends on the quantitative relationship between the cost of unit greenness and the intensity of subsidies. The impact of the industrial standard for non-green products depends on the intensity comparison between subsidies and carbon taxes. The more consumers can accept green products, the more the wholesale and retail prices of green and non-green products have to be adjusted downward. When consumer acceptance exceeds a certain threshold, the profit of the green manufacturer can surpass that of the non-green manufacturer, and then subsidies can be appropriately reduced. Both retailer cooperation and manufacturer cooperation can make the total profit of the entire supply chain competition system greater than that of the completely independent competition state, but when both supply chains enter the manufacturer-retailer cooperation mode, the total profit is not as good as that of the completely independent state, which means that centralized decision-making in the supply chain is not always superior to decentralized decision-making.</div></div>","PeriodicalId":55220,"journal":{"name":"Computers & Industrial Engineering","volume":"203 ","pages":"Article 110957"},"PeriodicalIF":6.7,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143509545","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}

Competition in the electricity selling market is highlighted, and introducing new challenges related to price bidding has become a new problem in power marketization. Following the latest reforms in the electricity selling market, an increasing number of power trading platforms have appeared in the electricity selling market, and the differentiated competition of service quality has become an essential means for these platforms to obtain users. Therefore, this paper studies the decision-making for service competition among power trading platforms under different power market structures such as monopoly, oligopoly and competitive market, and explores the optimal differentiation strategy for power trading platforms. The results show that: (1) Under different electricity selling market structures, the service quality level and service charge formation of the power trading platforms are related to the service input coefficient of the platform, and the changing relationship between these variables is also significantly affected by the market concentration degree in the competitive market; (2) The profit of the power trading platform is closely related to the level of its service quality, showing notable variations across different market structures; (3) Platform service charges are also related to the degree of differentiation of service quality and the degree of mismatch of users’ service expectations under the competition of platforms. Platforms offering high-quality services are more sensitive to changes in service quality differentiation compared to those offering lower quality services. This study can not only enrich the power market competition theory and provide theoretical reference for the competitive decision-making of power trading platform, but also provide theoretical guidance for developing high-end competition in the electricity selling market in the process of China’s electricity selling market reform.</div></div>","PeriodicalId":55220,"journal":{"name":"Computers & Industrial Engineering","volume":"203 ","pages":"Article 110956"},"PeriodicalIF":6.7,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143520267","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}

Although data-driven approaches have become a powerful tool for RUL prediction, most studies only focus on improving model structure and ignore the characteristics of the data itself. Due to changes in the environment and operating conditions, monitoring data often show non-linearity, non-stationarity and high noise, which affects the accuracy of prediction. Therefore, this paper proposes a dual-path prediction architecture based on time series decomposition and degradation correction (DP-TSDDC) to mine fine-grained information in the data in a targeted manner. First, the time series decomposition is used to extract trend components and non-stationary components from the data. Then, the dual-path architecture is used to select networks in a targeted manner according to the characteristics of each component. For the trend component, the temporal convolutional network is introduced to extract the engine’s long-term degradation features; for the non-stationary component, the Patch idea is used for data preprocessing, the long short-term memory is used within the Patch to capture detail features, and the multi-head attention is used between the Patch to capture global correlation features. Then, based on the gated linear unit and the nonlinear relationship between each feature, the features are enhanced and adaptively fused. At the same time, the degradation correction constraint is established based on physical knowledge to reduce the impact of data noise on the prediction results. Finally, the prediction effect of the DP-TSDDC method is verified by experiments on the CMAPSS and N-CMAPSS datasets.</div></div>","PeriodicalId":55220,"journal":{"name":"Computers & Industrial Engineering","volume":"203 ","pages":"Article 110964"},"PeriodicalIF":6.7,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143474813","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}

Therefore, we develop an evolutionary game model among core hospitals and member hospitals within a medical consortium. Firstly, we compute replication dynamic equations to understand the strategic interactions and evolutionary dynamics of information sharing within a medical consortium. Secondly, we analyze the local stability of the game model evolution and derive the evolutionary stability strategy (ESS) under different parameter constraints. Thirdly, to analyze the parameter sensitivity, we construct a scale-free network for numerical simulation experiments. As the network evolves, the edges among nodes and the strategy choices of nodes in this network likewise change.
