ABSTRACT The berth allocation problem (BAP) in a maritime container terminal is defined as a feasible allocation of berths to incoming vessels. In this paper, we developed a fuzzy mathematical programming model for continuous and dynamic BAP. It is assumed that the arriving time of vessels is imprecise, in the sense that the vessels can have an advance or delay but only up to a permitted tolerance.  Fuzzy sets are used to represent the imprecision. α - cuts method is applied to the model solution.  The proposed model has been codified in CPLEX solver and evaluated in different instances. The obtained results show that the proposed model can help the container terminal managers, since it has available berth plans with different degrees of allowed advance or delay, which are optimized according to the waiting time.

Palabras clave : alpha - cuts; fuzzy sets; imprecision; fuzzy optimizaticon; berth allocation problema.
