This paper systematically reviews the literature on SCND, analysing proposed mitigation strategies and the methods used for their integration into quantitative models. First to understand the key failure drivers SCND literature is categorised using geography, with local, regional or global disruptions linked to vulnerable sections of a SC. Second, the strategies used in mathematical models to increase SC resilience are categorized as proactive, reactive, or SC design quality capabilities. Third, the relative performance of mitigation strategies is analysed to provide a comparison, identifying the most effective strategies in given contexts. Forth, mathematical modelling techniques used in resilient SCND are reviewed, identifying how strategies are integrated into quantitative models.

Our newly proposed variant, named reinforcement learning CMSA (RL-CMSA), makes use of a reinforcement learning (RL) mechanism trained online with data gathered during the search process. In addition to generally outperforming standard CMSA, this new variant proves to be more flexible as it does not require a greedy function for the evaluation of solution components at each solution construction step. We present RL-CMSA as a general framework for enhancing CMSA by leveraging a simple RL learning process. Moreover, we study a range of specific designs for the employed learning mechanism. The advantages of the introduced CMSA variant are demonstrated in the context of the far from most string and minimum dominating set problems, showing the improvement in performance and simplicity with respect to standard CMSA. In particular, the best performing RL-CMSA variant proposed is statistically significantly better than the standard algorithm for both problems, obtaining 1.28% and 0.69% better results on average respectively.","PeriodicalId":8215,"journal":{"name":"Annals of Operations Research","volume":"39 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142251156","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}

When used efficiently, financial resources may improve universities’ quality of research and teaching, and therefore their positions in world university rankings. However, despite the relevance of financial efficiency to university placement in academic rankings, universities’ total available financial resources appear much more significant. In the present study, we propose an innovative methodology to determine realistic ranking targets for individual universities, based on their available financial resources. In particular, we combine data envelopment analysis, as developed by Banker et al. (Manag Sci 30(9):1078–1092, 1984), and a directed Louvain community detection algorithm to examine 318 universities across five countries, considering their ARWU scores alongside key financial indicators (i.e., long-term physical capital, total operating revenues). We identify clusters of universities with similar financial profiles and corresponding ARWU scores, as well as universities that have optimised their use of financial resources, representing benchmarks for similar universities to emulate. The approach is subsequently applied to Italian universities, as a specific national case. The findings may be useful for policy makers and university managers seeking reliable strategies for climbing academic rankings, particularly in countries with limited public investment in higher education.","PeriodicalId":8215,"journal":{"name":"Annals of Operations Research","volume":"9 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142251121","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 this study, we aim to propose a new forecasting approach to predict the demand for new energy vehicles (NEVs) by incorporating perceived quality measures extracted from online reviews into the traditional Bass model. To this end, we consider three crucial dimensions (i.e., emotional experience, defect perception, and brand/product image) and adopt text analysis techniques to mine perceived quality information from online reviews for NEVs comprehensively. Coping with the limited datasets, we further dynamically incorporate the mined perceived quality into the Bass model to improve the accuracy of new energy vehicle (NEV) demand forecasting. Finally, we meticulously conduct a series of experiments with crawled online reviews and historical sales of distinct NEV models. The experimental results demonstrate that the perceived quality measures identified from online reviews jointly affect the consumers’ purchasing decisions, and effectively enhance the performance of the NEV demand forecasting. Furthermore, some interesting and important findings are achieved based on the proposed methodology, including the time-lag effect of perceived quality on consumers’ purchasing decisions and the formulation of specific product strategies based on demand trends.","PeriodicalId":8215,"journal":{"name":"Annals of Operations Research","volume":"198 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142251123","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}

Considering the prevalence of rebate promotions and the downstream retailer’s optimism on the effect of rebating consumers, we incorporate rebate promotions, retailers’ optimism, and the corresponding information asymmetry issue into the manufacturer’s wholesale-ordering contract design problem. We find that with rebate promotions, the wholesale price and the order quantity should be higher than without rebate promotion. Specially, under the manufacturer-rebate strategy, the wholesale price and the order quantity should increase with the manufacturer’s rebate and the retailer’s optimism. However, under the channel-rebate strategy, the order quantity (the wholesale price) is no longer affected by the manufacturer’s rebate (the retailer’s optimism). Moreover, when the retailer’s optimism is private information, the retailer’s information distortion behaviors under the two rebate strategies are similar, but the manufacturer should accept different kinds of wholesale price-order quantity contract menus to reveal the retailer’s information and maximize profits. Specifically, under the manufacturer-rebate strategy (the channel-rebate strategy), differentiated contracts (a pooling contract) to different types of retailers are optimal. Besides, under the manufacturer-rebate strategy, the value of the rebate can play a moderating role in contract design. Hence, when the rebate is exogenously decided, the manufacturer can punish the retailer who is likely to distort information by decreasing the rebate.","PeriodicalId":8215,"journal":{"name":"Annals of Operations Research","volume":"65 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142251157","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}

Recently, platforms have adopted the hybrid bundling (HB) strategy that provides a bundled service of digital games in addition to P2P games. This strategy has the potential to facilitate the growth of digital games and address efficient decarbonization of physical copies of games. This study develops a theoretic model to explore whether the platform should adopt HB and, if so, what are the optimal value and price of the bundled service. We find that HB benefits profits when the usage cost of the bundled service is lower than that of P2P games, the unit price of P2P games is relatively high, and the spillover effect is low. Under such circumstances, the platform decides to provide a low-value and high-price bundled service to supplement P2P games. Moreover, when the usage cost of the bundled service is higher, HB benefits market size which also promotes digital games and reduces carbon emissions. Under such circumstances, when the unit price of P2P games is high, the platform provides a high-value and low-price service; otherwise, a low-value and low-price service. Interestingly, HB cannot simultaneously benefit both profits and market size. We find that a win–win–win situation exists for the platform, players, and social welfare when HB is profitable for the platform. When HB expands market size, it is always beneficial to players but may hurt social welfare. Finally, the bundled service may lead to social inefficiency.","PeriodicalId":8215,"journal":{"name":"Annals of Operations Research","volume":"1 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142251158","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}
