Maritime transportation is the backbone of international trade but ships emit a large amount air pollutants at ports. To encourage to use clean energy while berthing port, subsidies are provided ship operators that and subsidy generally determined based on subjective judgment. We, therefore, examine optimal design for government-operated ports, aiming balancing environmental benefits expenses. ...

The recent retirement of the Space Shuttle program has prompted NASA to begin outsourcing development of future technologies for transporting supplies and humans to the International Space Station (ISS). Any spacecraft approaching the ISS for docking or berthing is required to estimate its own position relative to the Space Station. We examine a problem of placing sensors on the ISS to aid in p...

Autonomous berthing is the last step to achieving autonomous operation of unmanned surface vehicles (USVs). Due significant disturbance wind, waves, and currents uncertainties model, it difficult realize berthing. For case obstacles dynamics USVs, transformed into three steps including path planning, tracking, motion control USVs in paper. A new advanced Dubins-RRT algorithm proposed for which ...

In a changing climate, ship speed optimization plays an important role in energy conservation and emission reduction. order to establish dual-objective model of minimizing operating costs reducing carbon emissions, fuel costs, berthing fixed cost during sailing cycles, the reduction strategies ships using MGO control areas AMP ports are taken into account. The PSO algorithm is adopted find Pare...

Ant Colony Optimization (ACO) is a paradigm that employs a set of cooperating agents to solve functions or obtain good solutions for combinatorial optimization problems. It has previously been applied to the TSP and QAP with encouraging results that demonstrate its potential. In this paper, we present FF-AS-SBP, an algorithm that applies ACO to the ship berthing problem (SBP), a generalization ...

We focus on the integrated seaside operations in container terminals, namely the integration of berth allocation, quay crane assignment and quay crane scheduling problems. We first develope a mixed-integer linear programming formulation. Then, we propose an efficient cutting plane algorithm based on a decomposition scheme. Our approach deals with berthing positions of the vessels and their assi...
