The road transportation contributes to a large portion of global carbon emissions each year. This carbon emission can be significantly reduced through collaboration among carriers. In this paper, a multi-round combinatorial double auction with both requests exchange and carbon emission permits trading is proposed for carrier collaboration, where each carrier may play a double role as both a seller and a buyer. In each round of the auction, the auctioneer announces the outsourcing price of each request and the unit trading price of emission permits. Each carrier then determines and bids for mutually exclusive request bundles to outsource and insource, along with their maximum and minimum trading volumes of emission permits. After receiving the supply and demand bids, the auctioneer tentatively reassigns requests and reallocates emission permits among carriers. At the end of each round, the outsourcing price of each request and the unit trading price of emission permits are updated based on the bids in previous rounds. Computational study shows that the proposed auction can generate more profits to carriers and reduce total carbon emissions significantly.

承运人合作的多轮组合双重拍卖，允许以零担运输进行交易

公路运输每年占全球碳排放量的很大一部分。通过运营商之间的合作，可以显著减少这种碳排放。在本文中，提出了一种多轮组合双重拍卖，同时具有请求交换和碳排放许可证交易，用于运营商协作，其中每个运营商都可以同时扮演卖方和买方的双重角色。在每一轮拍卖中，拍卖人都会公布每笔请求的外包价格和排污许可证的单价。然后，每个运营商确定并投标相互排斥的外包和内包请求捆绑包，以及他们的排放许可证的最大和最小交易量。在收到供需投标后，拍卖师会试探性地重新分配请求并在承运人之间重新分配排放许可证。在每轮结束时，每次申请的外包价格和排污许可证的单交易价格都会根据前几轮的投标情况进行更新。计算研究表明，拟议的拍卖可以为运营商带来更多利润，并显着减少总碳排放量。
