ABSTRACT

As water resources become increasingly scarce, manufacturers in high-water-consumption (HWC) industries are trying to seek water-saving services (WSS) from a WSS provider to reduce water consumption in the product-manufacturing/service-providing process. In this context, the game-theoretical decision models for dual competing HWC manufacturers under the scenario without/with WSS are developed, analyzed and compared respectively, the corresponding numerical and sensitivity analyses for all models are conducted and compared, on this basis, the corresponding management insights are summarized in this article. The research results indicate that: (1) Introducing a water-saving service (WSS) provider, conducting water-saving initiatives and adopting the cooperative strategy in the WSS supply chain are beneficial to enhancing the competitive advantage and improving operational performance, social welfare and consumer surplus for the HWC manufacturers. (2) Reducing product cost and reducing water consumption quantity per unit product are beneficial to improving the operational performance and social welfare for all stakeholders in the competition. (3) Making a proper water price could effectively motivate the HWC manufacturers to introduce water-saving service (WSS) and conduct water-saving initiatives. (4) Reducing water-saving costs is beneficial to improving the operational performance and social welfare for the WSS supply chain.

摘要

随着水资源的日益稀缺，高用水量（HWC）行业的制造商正试图从WSS提供者那里寻求节水服务（WSS），以减少产品制造/服务提供过程中的用水量。在此背景下，分别开发，分析和比较了双竞争HWC制造商在无WSS /有WSS情况下的博弈决策模型，并在此基础上对所有模型进行了相应的数值和敏感性分析，并进行了比较。本文总结了管理的见解。研究结果表明：（1）介绍了节水服务提供商（WSS），在WSS供应链中开展节水举措和采取合作策略，对于增强HWC制造商的竞争优势，改善运营绩效，社会福利和消费者剩余均有利。（2）降低产品成本，减少单位产品耗水量，有利于提高比赛中所有利益相关者的经营业绩和社会福利。（3）制定适当的水价可以有效地刺激HWC制造商引入节水服务（WSS）并开展节水举措。（4）降低节水成本有利于改善WSS供应链的运营绩效和社会福利。（2）降低产品成本，减少单位产品耗水量，有利于提高比赛中所有利益相关者的经营业绩和社会福利。（3）制定适当的水价可以有效地刺激HWC制造商引入节水服务（WSS）并开展节水举措。（4）减少节水成本有利于改善WSS供应链的运营绩效和社会福利。（2）降低产品成本，减少单位产品耗水量，有利于提高比赛中所有利益相关者的经营业绩和社会福利。（3）制定适当的水价可以有效地刺激HWC制造商引入节水服务（WSS）并开展节水举措。（4）减少节水成本有利于改善WSS供应链的运营绩效和社会福利。
