Maritime routing and speed optimization with emission control areas

Optimization in maritime inventory routing

A joint routing and speed optimization problem

Vehicle speed plays a significant role on fuel consumption and greenhouse gas emissions in freight transportation. We study a general joint routing and speed optimization problem with the goal of minimizing the total fuel, emission, and labor costs; the fuel consumption and emission rate is allowed to be an arbitrary strictly convex function of vehicle speed. We propose a novel set partitioning...

Ship speed optimization: concepts, models and combined speed-routing scenarios

The purpose of this paper is to clarify some important issues as regards ship speed optimization at the operational level and develop models that optimize ship speed for a spectrum of routing scenarios in a single ship setting. The paper’s main contribution is the incorporation of those fundamental parameters and other considerations that weigh heavily in a ship owner's or charterer's speed dec...

A new multi-objective model for berth allocation and quay crane assignment problem with speed optimization and air emission considerations (A case study of Rajaee Port in Iran)

Over the past two decades, maritime transportation and container traffic worldwide has experienced rapid and continuous growth. With the increase in maritime transportation volume, the issue of greenhouse gas (GHG) emission has become one of the new concerns for port managers. Port managers and government agencies for sustainable development of maritime transportation considered "green ports" t...

High Speed Networks OPTIMIZATION FLOW CONTROL WITH NEWTON-LIKE ALGORITHM

We proposed earlier an optimization approach to reactive flow control where the objective of the control is to maximize the aggregate utility of all sources over their transmission rates. The control mechanism is derived as a gradient projection algorithm to solve the dual problem. In this paper we extend the algorithm to a scaled gradient projection. The diagonal scaling matrix approximates th...
