This paper addresses the Uncapacitated Plant Cycle Location Problem, a location-routing problem aimed at determining a subset of locations to set up plants dedicated to serving customers. An optimization model is proposed to define the problem and solve it in small-size problem instances. With the aim to solve the problem in medium and big instances, a Greedy Randomized Adaptive Search Procedure with Probabilistic Learning Model is created. The computational results indicate the high performance of this algorithm in terms of the quality of solutions and on computational time.

An intelligent system which integrates Artificial Intelligence techniques and simulation tools is proposed to aid terminal managers. The system combines an intelligent evolutionary algorithm to generate high quality schedules for the cranes with a simulation model that incorporates uncertainty and the impact of internal delivery vehicles.

The paper solves the relocation problem in a maritime container terminal minimizing the “operating cost”, a cost proportional to the distance covered by the crane to move the containers that can be adapted to different measures like time, energy consumption, and more. An optimization model is proposed to define the problem, and an A* exact algorithm and a hybrid heuristic algorithm are created to solve it. The heuristic technique is aimed to solve the problem with good quality results in short computational times.

This paper solves the relocation problem in maritime container terminals minimizing the waiting times of a customer for a container. The main aim of this problem is improving the quality of service (QoS) of the terminal. An optimization model and a heuristic algorithm are proposed to solve the problem. The heuristic algorithm returns good quality solutions in short computational times.

In this paper the software Problem MetaHeuristic Solver is described. This tool allows to create, configure and execute heuristic algorithms in different kinds of problems using an intuitive user interface. The main goal of the software is the study of the behavior of heuristic algorithms in different situations and extract useful information about its execution, with the aim to help in education of this type of algorithms.
