This study uses the winner determination problem (WDP) to integrate auction transportation procurement with decisions related to production scheduling. The basic problem arises when a manufacturer has to clear a combinatorial auction to decide whether to cover transportation needs by using the in‐house fleet or to procure transportation through auction. Thus, the manufacturer should include an additional decision level by integrating the WDP with production scheduling to gain efficiency and achieve savings in the logistics system. To the best of our knowledge, this is the first time production and transportation procurement problems are being solved simultaneously in an integrated manner. The study proposes a mathematical formulation and develops two heuristic approaches for solving the integrated problem. Extensive computational experiments and sensitivity analyses are reported to validate the model, assess the performance of the heuristics, and show the effect of integration on total cost.

通过组合拍卖将生产计划和运输采购整合在一起

本研究使用获胜者确定问题（WDP）将拍卖运输采购与与生产计划有关的决策整合在一起。当制造商必须通过组合拍卖来决定是使用内部车队来满足运输需求还是通过拍卖来采购运输时，就会出现基本问题。因此，制造商应通过将WDP与生产计划集成来增加决策水平，以提高效率并节省物流系统。据我们所知，这是第一次以集成的方式同时解决生产和运输采购问题。该研究提出了数学公式，并开发了两种启发式方法来解决集成问题。
