我们实证研究交通规划中的建设性和阻塞力概念。我们的主要问题是这些概念在协同运输中代表什么。我们通过研究涉及八家公司的森林运输现实案例中的成本分配和联盟结构问题来解决这个问题。在这种情况下，合作的潜在节省约占9%。我们发现，球员更集中地位于往往受益于核仁分配，它只考虑到建设性的权力。其他的方法，考虑到阻断能力，即modiclus和SM-核仁，校正相对于那些在更外围的区域的中心球员的相对重要性。封锁力量承认，作为一个区块，更外围的公司仍然对合作至关重要，尽管它们之间几乎没有合作的机会。我们的主要结论是，将阻塞功率作为标准的成本分摊规则的协同规划在交通运输是很重要的，特别是在这种情况下，该联盟由一个或几个位于中心的公司和几个外围公司。仅仅基于建设性力量的方法可能会极大地有利于中央公司，损害维持联盟的可能性。
We empirically investigate constructive and blocking power concepts in transportation planning. Our main question is what do these concepts represent in collaborative transportation. We address it by studying cost allocation and coalition structure problems in a real-world case on forest transportation involving eight companies. The potential savings of collaboration in this case account for about 9 %. We find that players more centrally located tend to benefit from the nucleolus allocation, which takes into account only the constructive power. Other methods, which take into account the blocking power, namely the modiclus and the SM-nucleolus, correct the relative importance of the central players with respect to those in more peripheral areas. The blocking power acknowledges that the more peripheral companies, as a block, are still crucial to the collaboration, despite among themselves they have little opportunities for collaboration. Our main conclusion is that incorporating the blocking power as a criterion in a cost sharing rule for collaborative planning in transportation is important specially in the case where the coalition consists of one or few centrally located companies and several peripheral companies. A method based merely on the constructive power might extremely benefit the central companies, hurting the possibilities of sustaining the coalition.
