面向众包物流的双边组合拍卖机制
首发时间：2024-11-12
摘要：共享经济的兴起促使众包物流成为新型运作模式，企业通过外包运输任务给大众群体来降低成本。然而，传统固定定价模式难以激励参与者，导致资源分配效率低下。为解决这一问题，提出了一种基于双边组合拍卖的机制，以提升众包物流中的资源分配效率。首先构建了以社会福利最大化为目标的机制设计模型，允许需求方对不同运输路线组合进行投标。为了避免因运输路线多样化导致的预算赤字问题，提出了一种结合"填充"方法与vcg机制的双边组合拍卖模型。结果表明，该机制能够有效激励需求方和配送员参与竞拍并披露真实估值，吸引更多市场主体参与交易，提升交易数量。所提双边组合拍卖机制能够提升众包物流市场中的分配效率，促进共享经济的协同发展，推动物流行业的长远进步。?????

a bilateral combinatorial auction mechanism for crowdsourced logistics
abstract：the rise of the sharing economy has led to crowdsourcing logistics as a new mode of operation, where companies reduce costs by outsourcing transport tasks to mass groups. however, the traditional fixed pricing model is difficult to incentivise participants, leading to inefficient resource allocation. to solve this problem, a mechanism based on bilateral portfolio auction is proposed to enhance the resource allocation efficiency in crowdsourcing logistics. a mechanism design model aiming at social welfare maximisation is first constructed to allow demand-side bidding for different transport route combinations. in order to avoid the budget deficit problem caused by the diversity of transport routes, a bilateral portfolio auction model combining the \'padding\' method and the vcg mechanism is proposed. the results show that the mechanism can effectively incentivise demand-side and distribution operators to participate in the auction and disclose the true valuation, attracting more market players to participate in the transaction and increasing the number of transactions. the proposed bilateral portfolio auction mechanism can improve the allocation efficiency in the crowdsourcing logistics market, promote the synergistic development of the sharing economy, and promote the long-term progress of the logistics industry.
