In a slot exchange co-operation, participating carriers seek to benefit in which their surplus of controlled capacities can be shared to exchange slots belong to partners for their shortages. To each participant, whether the exchanged conditions can bring more benefits is based on its slot allocation planning. This paper introduces a practical slot exchange contract for multiple short sea loops between two co-operative carriers. Two integer programming models for maximizing the concerned profits are proposed to satisfy the expected demand level and shipping properties. One of the models merely considers slot exchange as the practical planning, and the other one includes slot purchase additionally. Decision results can assist the studied company to pursue an optimal allocation with consideration of exchanged slots for the involved lines. Moreover, sensitivity analyses including fixed exchanged condition, swap allowance influence, and purchase price assessment are carried out for measuring the impact of relevant variables to the profits.
