In this paper, we claim that the operation schedule of automated stacking cranes (ASC) in storage yard container terminals can be built effectively and efficiently by using a crane dispatching policy, propose noisy optimization algorithm named N-RTS derive such policy efficiently. To select job for an ASC, our uses multi-criteria scoring function to calculate score each candidate weighted summa...

The aim of the article is finding an optimal set of resources for the BCT container terminal. The pool of available resources consists of three types: quay cranes, trucks (tug-masters), and yard cranes. The article illustrates applicability of BCT logistical model based on Arena simulation package for choosing a resource set with known resource productivity values, initial prices and operationa...

In this paper an hybrid model for scheduling crane movements is presented. Cranes sharing the same track are considered. Cranes can reach any location along the track performing loading or unloading operations. As cranes share the same track their movements are constrained to avoid over crossing; tasks deadlines and priorities are also considered. Scheduler output are the assignment of the task...

Between 2000 and 2004, serum samples collected annually from captive cranes at the International Crane Foundation (ICF) were analyzed for the presence of West Nile virus (WNV) antibodies using a plaque reduction neutralization test. Eighteen individual cranes representing 8 species were identified with positive titers (geometric mean = 188, range 40 – 1280, n = 29). Whooping cranes (Grus americ...

The paper deals with solution of logistic problem for converter production of metallurgical enterprises. A developed multiagent simulation model of converter production is applied to solve the problem. This model allows assessing the different variants of the cranes motion between steelmaking aggregates. Three variants of the cranes motion have been considered during experiments with the model....

Workers in ports work with and close proximity of heavy machinery. Quay cranes used for moving containers between ships the dockside yard are one most accident-prone equipment types. For picking up containers, these equipped spreaders, i.e. lifting devices which lowered down on top lock to them mechanically. We concerned here monitoring a quay crane spreader so as make sure that safe clearance ...

This paper proposes a new idea for allocating handshake area of an automated container yard. A block yards (CY) consists two areas, which are the import (waterside) and export (landside) areas. The CY has major activities (loading unloading), where both served by Twin Automatic Stacking Cranes (Twin-ASCs). in middle serves as temporary slot ASCs. situation causes imbalance between ASCs when dem...
