Abstract

An integrated problem of berth allocation and stockyard assignment in dry bulk ports is investigated. The neighbourhood storage slots with the same type of cargo can be consolidated to hold a whole stockpile in the problem. The optimisation criteria of the problem are to minimise the total transshipment and storage costs of all the cargoes, as well as the total berthing time of all the ships. The problem is mathematically formulated as a mixed-integer nonlinear programming model. A genetic algorithm is proposed to solve the problem. Experiments based on instances with different scales validate both the mathematical model and the genetic algorithm. The experimental results illustrate that the algorithm can provide better solutions within a shorter time than directly solving the mathematical model for large-scaled instances.
