چکیده

This work introduces a fuzzy optimization model, which solves in an integrated way the berth allocation problem (BAP) and quay crane (QCAP). The is solved for multiple quays, considering vessels’ imprecise arrival times. model optimizes use of quays. BAP + QCAP, NP-hard (Non-deterministic polynomial-time hardness) combinatorial problem, where decision to assign available quays each vessel adds more complexity. times variables—berth departure times—are represented by triangular numbers. obtains robust berthing plan that supports early late arrivals also assigns cranes vessel. was implemented CPLEX solver (IBM ILOG Optimization Studio); obtaining short time optimal solution very small instances. For medium instances, undefined behavior found, (optimal or not) may be found. large no solutions were found during assigned processing (60 min). Although applied n = 2 it can adapted “n” must with metaheuristics.

Robust Scheduling for Berth Allocation and Quay Crane Assignment Problem

Decision makers must face the dynamism and uncertainty of real-world environments when they need to solve the scheduling problems. Different incidences or breakdowns, for example, initial data could change or some resources could become unavailable, may eventually cause the infeasibility of the obtained schedule. To overcome this issue, a robust model and a proactive approach are presented for ...

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...

Simultaneous Optimization of Berth Allocation, Quay Crane Assignment and Quay Crane Scheduling Problems in Container Terminals

In this work, we focus on the integrated planning of the following problems faced within the context of seaside operations at container terminals: berth allocation, quay crane assignment, and quay crane scheduling. First, we formulate a new binary integer linear program for the integrated solution of the berth allocation and quay crane assignment problems called BACAP. Then we extend it by inco...
