Within these platforms, national brand manufacturers (NBMs) face a choice between two distinct business models for selling their products: the wholesale model or the agency model. Additionally, the e-commerce platform itself may introduce a store brand (SB) that competes with the NBM’s national brand (NB). We have delved into the intricate dynamics at play between the NBM’s selection of a business model and the e-platform’s decision to introduce an SB, employing a game-theoretic model. Our investigation has yielded valuable insights: First, when an NBM opts for the wholesale model, the e-platform consistently introduces an SB. Conversely, under the agency model, the e-platform refrains from introducing an SB if both the commission rate for the NB product and the planned quality of the SB are sufficiently high. If the e-platform introduces the SB with low quality, the NBM may switch from an agency model to a wholesale model at a relatively low commission rate for the e-platform. Furthermore, the e-platform tends to favor an intermediate level of quality for the SB. This approach allows the SB to generate substantial revenue without engaging in intense competition with the NB. Both the NBM and the e-platform tend to prefer a moderate commission rate. Finally, our analysis delves into the impact of channel price leadership on the equilibrium outcomes. In a surprising turn, under the agency model, it proves advantageous for both firms to relinquish channel price leadership. Additionally, the NBM is more likely to adopt the wholesale model when it assumes the role of channel price leader. The e-platform is less likely to introduce SBs when it takes on the leadership position.","PeriodicalId":55161,"journal":{"name":"European Journal of Operational Research","volume":"234 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144664766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Green marketing promotes demand but requires the retailer to make extra investment. Product greenness depends on the actual realized carbon emission abatement (CEA). However, due to uncertainties during the production process, the realized CEA often less than its target level. To entice the retailer to pay more effort on green marketing, some manufacturers enhance the product greenness by taking proactive activities to hedge against CEA uncertainties, which is referred to as carbon emission hedging (CEH). To examine the effect of CEH on green marketing and channel performances, we proposed a CEH and green marketing mechanism (CG mechanism). Moreover, since the game follower usually exhibits fairness concerns, we also explore the various combinations of the retailer’s fairness concern behaviour and the manufacturer’s attitude towards this behaviour. We find that adopting the CEH strategy promotes the green marketing and the CG mechanism always coordinates the supply chain when the retailer is fairness-neutral or his fairness-concern level is not sufficiently high (e.g. λ₁ ≈ 0.9). Besides, lower consumer price sensitivity and higher consumer green marketing/product greenness sensitivity/amplification effect of CEH on green marketing improve the market demand and the retailer’s profit, but not necessarily benefit the manufacturer. Additionally, being fairness-concerned is not always beneficial for the retailer and ignoring the retailer’s fairness concern often harms the manufacturer.","PeriodicalId":55161,"journal":{"name":"European Journal of Operational Research","volume":"109 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144664983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In fact, the future demand of new or existing products is complex to predict due to its intricate relationship with pricing strategies and consumer behaviors, whereas optimizing product assortment requires capturing inter-product effects and the impact on inventory management and costs. Tackling these interconnected challenges effectively remains a key issue in retail planning. In this paper, we focus on low-margin, high-volume brick-and-mortar retail businesses, in which the baseline product price is fixed by the supplier, but markdowns and promotions can be leveraged to steer sales. We develop a multi-stage stochastic linear program that accounts for demand uncertainty and jointly optimizes product assortment, inventory, and promotion decisions, while embedding a novel demand elasticity formulation. To define the input demand scenarios to the stochastic program, we consider historical sales data by an Italian electronics retailer aggregated by product category, calibrate a stochastic process to this data, and construct a scenario tree that captures the process dynamics. Extensive numerical experiments show that the model can be solved efficiently with a commercial optimization solver for instances at varying number of products, categories, and scenarios. Furthermore, we show that the expected profit from our stochastic program increases compared to a forecast-based reoptimization policy by 15%, an expert-based heuristic inspired by current practice by 22%, and a benchmark that neglects demand elasticity by 5%. Our approach can thus support in-store retail planners to enhance their competitiveness.","PeriodicalId":55161,"journal":{"name":"European Journal of Operational Research","volume":"29 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144664793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dynamic pricing could support this by incentivizing users while balancing supply and demand. We describe the usage of a round trip car sharing fleet by a continuous time Markov chain model, which reduces to a multi-server queuing model where hire duration is assumed independent of the hourly rental price. We present analytical and simulation optimization models that allow the development of dynamic pricing strategies for round trip car sharing systems; in particular identifying the optimal hourly rental price. The analytical tractability of the queuing model enables fast optimization to maximize expected hourly revenue for either a single fare system or a system where the fare depends on the number of cars on hire, while accounting for stochasticity in customer arrival times and durations of hire. Simulation optimization is used to optimize prices where the fare depends on the time of day or hire duration depends on price. We present optimal prices for a given customer population and show how the expected revenue and car availability depend on the customer arrival rate, willingness-to-pay distribution, dependence of the hire duration on price, and size of the customer population. The results provide optimal strategies for pricing of car sharing and inform strategic managerial decisions such as whether to use time- or state-dependent pricing and optimizing the fleet size.","PeriodicalId":55161,"journal":{"name":"European Journal of Operational Research","volume":"12 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144664794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
