At the other end, ML models require little or no domain knowledge to construct, are flexible, and can provide superior accuracy in data-rich environments, but cannot extrapolate, are data-inefficient and are black boxes. We investigate how to consolidate these opposite views to obtain the best of both worlds in the context of airline demand forecasting.

To address this issue and maximize profits, we have developed a contract that takes into account the costs of investing in preservation technology over a finite planning horizon. The arrangements incentivize the supplier and the retailer to establish coordination and determine not only the optimal price and schedule for replenishment but also the optimal investment required in preservation technology. We investigate the effectiveness of vendor managed inventory (VMI) and consignment with revenue-sharing models through an analysis of pricing and inventory decisions, followed by evaluating the channel performance and the distribution of profits. Contract parameters are defined under the equilibrium state to achieve advantageous relationships among supply chain partners by improving profits for both channel members. The finding shows that a VMI and consignment mechanism with a side payment arrangement could help coordinate channels in a non-cooperative setting. Still, performing the contract is easier in a cooperative setting. Both members could achieve optimal decisions for the wide-channel system without any additional payments, leading to increased profitability for all supply chain members. In an alternative approach, the retailer has the option to offer a subsidy alongside the revenue-sharing-only trading terms within a VMI and consignment by incorporating a generalized revenue-sharing scheme to facilitate coordination with the supplier.</p>","PeriodicalId":46686,"journal":{"name":"Journal of Revenue and Pricing Management","volume":"5 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142179835","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}

However, after restructuring the systems above and separating different sectors of this industry into independent enterprises, economic profitability became twice as important. In this paper, the issue of electricity pricing is examined from a retailer’s point of view. The retailer supplies electricity from various sources, including the electricity market, bilateral contracts, and renewable sources, and then tries to sell it to customers at the optimal price. Here, the objective function combines expected profit and the conditional value at risk as a risk measure. Because of demand responsiveness, the retailer can use pricing tools to manage customer demand. Besides customer demand, the electricity market price and power generation of renewable energy sources are stochastic, and the advantage of the chance-constrained programming approach is taken to cover the power balance risk. Eventually, a hybrid chance-constrained and scenario-based method is proposed to model the retail electricity pricing problem based on fixed and real-time pricing policies. Furthermore, the energy storage system is considered a tool to increase the expected profit and control environmental effects; pollution costs are considered for electricity supplied from non-renewable sources. The proposed model maximizes profit and reduces environmental effects by considering pollution costs. To show the effectiveness of the proposed model, a numerical example is presented and solved. Results show that profit is maximized by determining each source’s optimal selling price and power. Meanwhile, the energy storage system simultaneously increases this profit.</p>","PeriodicalId":46686,"journal":{"name":"Journal of Revenue and Pricing Management","volume":"69 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141782332","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}
