However, its acceptance is lower than that of fossil energy due to its inherent intermittency. This study is motivated by such challenges and seeks to overcome it by enabling electricity consumption through coordinated operation strategies for the hydro-wind-photovoltaic systems. To match electricity demand and maximize system power output, non-priority output scheduling should be used. This study presents a systematic nonlinear programming strategy coupled with a combined meta-heuristic approach. The programming aims to increase total power generation, control wasted power, and balance the fluctuation of fossil energy output. The programming makes use of the corresponding constraints for hydro, wind, and photovoltaic power generation. A scenario-based approach also considers the effects of seasonal meteorological factors on electricity output. To address NP-hard issues in complicated nonlinear programming, a hybrid cuckoo search technique and multiple objective particle swarm optimization are used. The combined meta-heuristic technique includes a flight and elimination mechanism to increase search capacity and accelerate convergence. The case study of a hydro-wind-photovoltaic system is then performed over a four-season scheduling horizon. The case supports the study's viability and efficacy. The findings demonstrate the developed methodology's ability to balance the three objectives. The optimal dispatch schedule is shown to reduce intermittency, ensure renewable energy acceptance, and then adjust the power source's installed capacity. This study's coordinated operation strategies promote a more efficient method of establishing MECS and help to reduce power grid risk.</div></div>","PeriodicalId":19529,"journal":{"name":"Omega-international Journal of Management Science","volume":"131 ","pages":"Article 103198"},"PeriodicalIF":6.7,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142422113","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}

First, contrary to the literature, our study shows that the retailer's use of strategic inventory benefits all supply chain members, irrespective of whether the wholesaler holds strategic inventory. Second, the strategic inventories of the wholesaler and the retailer suppress each other when the holding cost is low. Otherwise, the retail strategic inventory can stimulate the wholesale strategic inventory. Third, after the retailer employs strategic inventory, introducing wholesale strategic inventory will harm each supply chain member. However, after the wholesaler employs strategic inventory, introducing retail strategic inventory can benefit all members. For the entire supply chain, holding strategic inventory exclusively at the retailer is optimal. Fourth, when product durability is high, the supplier may suffer from the wholesaler's strategic inventory. Additionally, the retailer's strategic inventory can solve the time inconsistency problem associated with durable goods.

However, implementing carbon footprint reduction in logistics services generally incurs heavy costs. To distribute heavy costs and improve resource utilization, a novel strategy of logistics service sharing has played an important role. Nevertheless, it is still unclear, in a co-opetitive e-commerce market, how to make use of different approaches and what the impacts of logistics service sharing are. To answer these questions, we develop an analytical model where an e-commerce platform and a third-party seller compete for consumers who care about both the selling price and the logistics service carbon footprint. We assume that the platform builds his own logistics service system and can adopt two different approaches to cut carbon footprint, while the seller needs to outsource logistics services to the TPL service provider or the platform. The analysis shows that without logistics service sharing, the platform may be more willing to purchase carbon offset as the offset cost increases, and the availability of carbon offset can prompt the platform to increase his investment in green technology. By contrast, with logistics service sharing, the platform will be less willing to purchase carbon offset as the offset cost increases, and the usage of carbon offset will induce him to invest less in green technology. These findings highlight that logistics service sharing can change the platform's preference toward the two approaches and modify the relationship between them. Furthermore, we find that logistic service sharing can provide a win-win outcome for the platform and the seller, but is not necessarily helpful for reducing the total carbon footprint in the e-commerce supply chain as well as increasing consumer surplus and social welfare.</div></div>","PeriodicalId":19529,"journal":{"name":"Omega-international Journal of Management Science","volume":"131 ","pages":"Article 103205"},"PeriodicalIF":6.7,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142422138","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 response, platforms have begun offering direct financing (PDF) to their suppliers alongside traditional bank credit financing (BCF). Within the private (consortium) blockchain, the platform and the supplier (and the bank) achieve consensus on financial smart contract, enabling the execution of flexible contracts tailored to suppliers’ risk profile. We develop a game-theoretic model to examine the terms of smart contracts in different blockchains and further investigate the platform's optimal blockchain design. We find that PDF serves to safeguard the platform's commission income from high-interest BCF. Our analysis reveals that PDF is more likely to be provided to a risky supplier within the consortium blockchain, contrasting with outcomes observed within the private blockchain. As a result, the platform and the supplier could reach win-win, or win-lose outcomes within the private blockchain; while within the consortium blockchain, they tend to result in win-win or lose-win outcomes. Such incentive conflict could potentially hinder blockchain adoption. Our findings further provide the managerial insights guiding the platform's blockchain design: adopting consortium blockchain under moderate market potential and low or high supplier's risk, and adopting private blockchain otherwise. Furthermore, we consider the supplier's endogenous effort on reducing risk, and numerically demonstrate that blockchain may encourage or discourage the supplier's effort. Our research complements previous studies by investigating the interaction between the PDF provision and blockchain structures under uncertain supply disruption risk.</div></div>","PeriodicalId":19529,"journal":{"name":"Omega-international Journal of Management Science","volume":"131 ","pages":"Article 103200"},"PeriodicalIF":6.7,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142422116","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}

We find that a higher commission rate can incentivize the influencer to exert more efforts to convert fans, but also harms the brand by reducing the proportion of the livestream profit allocated to it and inhibiting it from transferring commission cost to consumers. Therefore, the brand may (not) be suggested to cooperate with the influencer when the commission rate is at a moderate (either low or high) level such that the twofold impacts of the commission rate are balanced (imbalanced).
