AB  - The paper presents M^X / M / c batch queues in which the group size is
given by the shifted-Poisson and Poisson-like distributions. This queue
model deduced the expressions for the specific cost ratio involving the
state probabilities, the utilization factor, the mean and the variance of the
group size. Proposed model discusses the total queuing system costs of
container at container yard (CY) and specific cost ratio to improve the best
values for container performances at CY. The analytical approach make
the model appropriate to analyze. The special cases can be solved exactly,
which is shown in another paper dealing with the application of this
methodological approach.

Container Yard (CY) as an Operational System based on a particular
batch arrival multi-server M^X / M / c queue described and analysed in
[4], where the batch size ( X ) has the shifted-Poisson and Poisson-like
distributions. Using a more general formula for such queue models, here
it is deduced the expressions for the specific cost ratio involving the state
probabilities, the utilization factor, the mean and the variance of the group

concerning the M /G/1 queue using the known general expression for
the specific cost ratio and the Pollaczek–Khintchine formula for the
M /G/1 queue. Moreover, we also present related numerical and
graphical results including the cases concerning the M /M /1 and
M / D/1 queues. The deduced formula gives a possibility for
comparison of values of specific cost ratio of different M /G/1 type
queues. The corresponding optimization is considered in the sense of
minimization of values of the appropriate specific cost ratio under some
constraints to the values  (the utilization factor). The proposed method
is exposed by some numerical experiments.

are expressed as a function on the utlization factor (  ) and the size of
every arriving group at the ramp ( g ). Related numerical and graphical

AB  - Performance of containers' flow at yard represents very important point of container terminals. The organization of container transport and stacking policies leads to less congestion and lower costs. Otherwise, containers wait in queue before they are serviced. This study presents an analytical approach for obtaining the average number of containers in queue. We proposed two models (constant and geometric) of bulk arrival multi-server queuing system. Traffic intensity and utilization factor are very important parameters that consist of data for arrival and service rate and number of servers (yard cranes). In this paper, we assume that there are three yard cranes that operate at container yard. A given numerical example for two models will improve the best values for performance of containers' flow at container yard.

AB  - We discuss dynamic system performance evaluation in the river port utilizing queuing models with batch arrivals. The general models of the system are developed. This system is modelled by M-X/M/n/m queue with finite waiting areas and identical and independent cargo-handling capacities. The models are considered with whole and part batch acceptance (or whole and part batch rejections) and the interarrival and service times are exponentially distributed. Results related to the batch blocking probability and the blocking probability of an arbitrary vessel in nonstationary and stationary states have been obtained. Numerical results and computational experiments are reported to evaluate the efficiency of the models for the real system.
