the aim of this study is to propose a new mixed integer linear programming (milp) model to find the minimum required number of yard cranes, rubber tyred gantry cranes (rtgcs), for completion the total amount of works at the end of planning horizon. in other word, we find the optimal number of yard cranes in a container terminal which completes the total amount of works. the paper supports the p...

This paper summarizes the most important advances of the used crane control technology in perspective of unmanned operation of container cranes. Unmanned operation with remote control support today is available for almost all types of new/existing rail mounted container cranes. Storage capacity is the limitation for most terminals today; unmanned operation offers optimum stacking density and pe...

The aim of this study is to propose a new mixed integer linear programming (MILP) model to find the minimum required number of yard cranes, Rubber tyred gantry cranes (RTGCs), for completion the total amount of works at the end of planning horizon. In other word, we find the optimal number of yard cranes in a container terminal which completes the total amount of works. The paper supports the p...

The population growth of endangered whooping cranes (Grus americana) is not consistent with species recovery goals, and the impact of parasite infection on whooping crane populations is largely unknown. Disease ecology and epidemiology research of endangered species is often hindered by limited ability to conduct invasive sampling on the target taxa. Accordingly, we hypothesized that sandhill c...

We analyzed the gizzards, and grits retained in the gizzards of 41 24 cranes that migrated to the Izumi Plain during the winter of 2015/2016 and died 25 there, either due to accident or disease. These included 31 Hooded Cranes (Grus 26 monacha) and 10 White-naped Cranes (G. vipio). We determined body weight, 27 gizzard weight, total grit weight and number per gizzard, and size, shape, and 28 su...

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....
