Abstract :
We deal with a transportation problem in a housing material manufacturer. The housing material manufacturer entrusts transportation of its products to two forwarding agents which handle regular transportation and small lot transportation. There are two objectives of the housing material manufacturer: one is to minimize the transportation cost and the other is to minimize the opportunity loss with respect to transportation time. Each of the two forwarding agents assigns drivers the transportation tasks so as to maximize its profit. We formulate the problem as a decentralized two-level integer programming problem and apply interactive fuzzy programming
