Motivated by two Pareto‐scheduling open problems where one criterion is the total (weighted) late work and the other criterion is the weighted number of tardy jobs, we show that 12 constrained scheduling problems unaddressed in the literature are binary NP$$ NP $$ ‐hard, implying that the Pareto‐scheduling versions of these problems are also binary NP$$ NP $$ ‐hard. Moreover, we introduce the concept of dummy due dates (DDD) for equal‐length jobs to be scheduled in equal‐length intervals. Intriguingly, we find that a DDD‐based technique outperforms the existing solution methods and improves the known time complexities of the related problems. In addition, we extend our research to the two‐agent scheduling model under the assumption of equal‐length or partially equal‐length jobs by including the total weighted late work as the criterion of one agent. For these problems, our results also improve the known time complexity results.","PeriodicalId":19120,"journal":{"name":"Naval Research Logistics (NRL)","volume":"19 1","pages":"537 - 557"},"PeriodicalIF":0.0,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90961914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meanwhile, suppliers that take on price risks typically seek further information on spot market prices. Furthermore, they need to consider whether to share the information with shipping companies as such information can affect shipping companies' decision on speed and, hence, their fuel consumption and shipper business. To study the refueling and information issues of the shipping supply chain, we describe a game between a shipping company and a supplier on the basis of a fuel supply contract. Results show that compared with the case without information sharing, the case with information sharing with a possibly lower spot price can bring higher profits for the shipping company and supplier. At this point, the shipping company will increase its navigation speed and benefit from the resulting increase in shipper business. Meanwhile, the supplier can benefit from the shipping company's increased fuel consumption. The supplier decides to share information with the shipping company before receiving signals only when the prediction accuracy is high, indicating that the supplier's prediction motivation is to sway the shipping company's risk assessment. Restricted by prediction costs, the supplier will not improve the prediction accuracy indefinitely, but such improvement can always benefit the shipping company. Hence, information prediction can be a win‐win strategy for the shipping company and supplier.","PeriodicalId":19120,"journal":{"name":"Naval Research Logistics (NRL)","volume":"10 1 1","pages":"522 - 536"},"PeriodicalIF":0.0,"publicationDate":"2023-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83591775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Information disclosure, consumer returns, and operational costs in omnichannel retailing","authors":"Jie Liu, Hui Xiong","doi":"10.1002/nav.22101","DOIUrl":"https://doi.org/10.1002/nav.22101","url":null,"abstract":"In the online retailing, consumers are commonly uncertain about the product's quality and fitness. To resolve these uncertainties, many pure e‐tailers adopt various omnichannel strategies to provide tactile product information for consumers. We build a model to investigate a pure e‐tailer's decision on whether to adopt an omnichannel strategy. Our result indicates that when the cost for each physical store is sufficiently low, the e‐tailer always adopts the omnichannel strategy regardless of the product quality. Moreover, the low‐quality e‐tailer's willingness to adopt the omnichannel strategy is nonmonotonic with the fitness probability when the travel cost factor is high. In contrast, if the cost for each physical store is moderate, the e‐tailer adopts the omnichannel strategy if and only if the product quality is above a threshold. The quality threshold may increase with the fitness probability. Higher fitness probability means a lower return rate and fewer benefits brought by the omnichannel strategy. Thus, the threshold of the quality is increased to guarantee a sufficiently large price increase when choosing the omnichannel strategy. Furthermore, when the cost for each physical store is high, the e‐tailer with a high‐quality product would abandon the omnichannel strategy if the fitness probability is moderate. Finally, we consider the scenarios in which the e‐tailer can endogenously determine the number of physical stores or provide a partial refund policy.","PeriodicalId":19120,"journal":{"name":"Naval Research Logistics (NRL)","volume":"1 1","pages":"376 - 391"},"PeriodicalIF":0.0,"publicationDate":"2023-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79560069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pun, Qiaoxi Zhang","doi":"10.1002/nav.22100","DOIUrl":"https://doi.org/10.1002/nav.22100","url":null,"abstract":"This article examines the information acquisition strategy of a dual‐channel supply chain, in which a manufacturer sells a product both through a retailer and through its own direct channel. Either the manufacturer or the retailer can acquire demand information from a third‐party marketing research company. The manufacturer first decides whether or not to acquire such information, and then the retailer decides whether or not to acquire information. This setup implies a signaling game (either the manufacturer or the retailer may have private demand information) with an endogenous information structure. We identify conditions under which neither of the firms will acquire demand information, even when the cost of implementation is negligible. We also show that information acquisition can have a negative impact on the retailer, the supply chain, customers, and society. The manufacturer who acquires information always prefers to share information with the retailer, which benefits the retailer. The retailer who acquires information, however, may not want to share information with the manufacturer. The managerial insight of our paper is that firms that have more accurate demand data must develop strategies for the appropriate use of that information, both in their own planning and within the context of their dual‐channel supply chain.","PeriodicalId":19120,"journal":{"name":"Naval Research Logistics (NRL)","volume":"140 1","pages":"340 - 357"},"PeriodicalIF":0.0,"publicationDate":"2023-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78582519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The variability and stochasticity of environmental conditions have a non‐negligible impact on the failure behavior of engineering systems. This article develops a reliability modeling and assessment framework for systems operating under a Markovian dynamic environment. The stochastic dynamic environment is characterized by a continuous‐time Markov chain. Using the cumulative exposure principle, the stochastic time scale, resulting from the cumulative effect of the Markovian dynamic environment, is computed via a Markov reward model. Based on the above settings, the system reliability model under the Markovian dynamic environment is developed. The maximum likelihood estimates and confidence intervals for the model parameters, including the transition rate matrix of the Markov chain, the reward rates of the Markov reward model, and the parameters of the baseline lifetime distribution, are obtained by utilizing the collected environment and lifetime data. The system reliability is then assessed with the estimated parameters. The effectiveness of the proposed framework are validated using simulation and through an application to a long‐term storage system. The results show that the unknown reliability model parameters can be accurately estimated, and the proposed model with the consideration of the cumulative effect of the Markovian dynamic environment can provide a more accurate reliability estimate than that without such a consideration.","PeriodicalId":19120,"journal":{"name":"Naval Research Logistics (NRL)","volume":"116 1","pages":"320 - 339"},"PeriodicalIF":0.0,"publicationDate":"2023-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88082658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
