中小型货运公司联盟内的合作运输规划（CTP）可以作为一种强有力的工具，以提高联盟成员的运营效率。在这种联盟中，来自不同承运人的运输请求被交换，以降低总的履行成本。本文研究了一组相互独立的承运人交换零担运输请求的CTP问题。考虑到所有合作伙伴的机队能力有限这一现实限制。为了保持自主性，联盟成员在CTP期间保持其敏感信息，包括客户付款和成本结构。提出了一种新的分散式CTP请求交换机制，只考虑车辆路径进行交换。它是测试一些新生成的实例和CTP的解决方案进行了比较，通过孤立的规划，没有合作和通过启发式方法获得的集中式规划问题。结果表明，我们的机制是非常有效和有效的实现潜在的成本节约CTP方面，即使明确考虑到容量限制和限制的信息曝光。
Collaborative transportation planning (CTP) within a coalition of small and medium-sized freight carriers can be used as a powerful instrument to improve the operational efficiency of the coalition members. In such coalitions, transportation requests from different carriers are exchanged in order to reduce the total fulfillment costs. In this paper, the CTP for a set of independent carriers exchanging less-than-truckload transportation requests is considered. The realistic restriction that all collaborating partners have only limited capacities in their fleets is included in the consideration. To keep their autonomy, coalition members keep their sensitive information including customer payments and cost structures unexposed during CTP. A new decentralized request exchange mechanism for CTP is proposed while only vehicle routes are considered for exchange. It is tested on some newly generated instances and the CTP solutions are compared with those obtained by isolated planning without collaboration and those obtained by a heuristic approach for the centralized planning problem. The results indicate that our mechanism is very efficient and effective in terms of realizing potential cost-savings by CTP, even when capacity limitations and restrictions on the exposure of information are explicitly considered.
