Efficient management of port resources plays a crucial role in reducing vessel stay times and avoiding the payment demurrage charges. In this paper, we focus on integrated Laycan Berth Allocation Quay Crane Assignment Problem, which considers three main decision problems an way: dynamic continuous Problem time-invariant Problem. second part, problem is extended to Specific Assignment, includes ...

in this study two indices of tempo and quantum of fertility for the city of tehran are calculated. the tables are based on data which have been collected in a survey in 1986. the sampling was administrated at two stages. at the beginning 158 geographical points were considered (the number of first birth order during 24 hours in tehran), then on the first stage 17 random geographical points were...

Seaport container terminals are source of many interesting large-scale optimization problems, which arise in the management of operations at several decision levels. In this paper we firstly illustrate a recently proposed framework, called two-stage column generation (Salani and Vacca, 2008), which is suitable for a particular class of large-scale problems, where the structure of the original f...

The management of a container terminal is a complex process that involves a vast number of decisions. The berth is the most important resource that affects the capacity of the terminal. The problem is here to allocate berths to arriving vessels and to determine which cranes in the berths process the docked vessels. For creating the berth schedule, the calling schedule of vessels, favourable ber...

An Integrated Approach to Managing Vessel Service in Seaports Efficient vessel service is of utmost importance the maritime supply chain. When serving a group incoming vessels, berth allocation and pilotage planning are two most important decisions made by seaport. Although they closely correlated, problem often solved sequentially, leading suboptimal or even infeasible solutions for services. ...

Productivity is an extremely important factor in the competitiveness of a container terminal. itself largely influenced by handling mechanisation, main task which to serve quay cranes on one side and yard other. One most effective types mechanisation this segment shuttle carriers, are used primarily larger terminals. The objective study was determine if they can also be effectively smaller term...
