The Cyber-Physical Internet (CPI) is a cutting-edge concept that brings together physical systems and cyber technologies to enable seamless interaction between the physical and virtual worlds. This innovative approach is revolutionizing the transportation industry by paving the way for a new era of logistics and transport networks. Introducing CPI into the procurement of transport services is leading to a re-evaluation of fundamental issues such as routing, mode choice and real-time pricing. This paper provides an in-depth discussion on the application of transport services procurement auctions in a CPI environment, with the aim of establishing a novel CPI-based trading platform for transport services using CPI technology, and calls the methodology proposed in this paper a meta-auction. The transport route allocation quandary is simplified into an auction model, where carriers truthfully submit unit route costs, and the winning carrier and pricing are determined using the single-unit Vickrey-Clark-Groves (VCG) method. To address scenarios with multiple carriers per network segment node, this paper proposes the multi-unit VCG auction method. Furthermore, the weighted affine VCG auction method is introduced, considering the weight of each network segment route. All three mechanisms are generalized VCG auctions, ensuring incentive compatibility, budget balance, allocation efficiency, and individual rationality. Case studies validate the effectiveness of the proposed methods, offering managerial insights based on key findings that are valuable for industry professionals and researchers in the CPI domain. This study highlights the transformative potential of CPI to revolutionize auctions for the procurement of transport services and underlines the benefits of combining physical and cyber technologies in auction design.

工业 5.0 中按需运输采购的元拍卖


信息物理互联网 （CPI） 是一个尖端概念，它将物理系统和信息技术结合在一起，以实现物理世界和虚拟世界之间的无缝交互。这种创新方法为物流和运输网络的新时代铺平了道路，正在彻底改变运输行业。将 CPI 引入运输服务采购，导致对路线、模式选择和实时定价等基本问题的重新评估。本文深入讨论了运输服务采购拍卖在 CPI 环境下的应用，旨在使用 CPI 技术建立一个基于 CPI 的新型运输服务交易平台，并将本文提出的方法称为元拍卖。运输路线分配的困境被简化为拍卖模型，其中承运商如实提交单位路线成本，并使用单件 Vickrey-Clark-Groves （VCG） 方法确定获胜的承运商和定价。针对每个网段节点多载波的场景，该文提出多单元 VCG 拍卖方法。此外，考虑了每个网段路由的权重，引入了加权仿射 VCG 拍卖方法。这三种机制都是广义的 VCG 拍卖，保证了激励兼容性、预算平衡、分配效率和个体合理性。案例研究验证了所提出的方法的有效性，根据关键发现提供了管理见解，这些发现对 CPI 领域的行业专业人士和研究人员很有价值。 本研究强调了 CPI 在彻底改变运输服务采购拍卖方面的变革潜力，并强调了在拍卖设计中结合物理和网络技术的好处。
