Abstract
It is proposed to evaluate various options for the mooring of a vessel at the berth of a cargo terminal by integer time intervals, which, when using Erlang's formulas, generalized to the case of the Markov process, can be used to solve the problems of planning loading and unloading operations on the company's ships, and should be presented in the form of a vector, the size of which is determined by the number of possible states of the "ship – berth" system.
 A method for assessing the time of servicing a loading and unloading operation by the terminal has been compiled, when observing a number of particulars corresponding to the usual histogram, and each value of the time interval corresponds to a certain bit of the histogram, a variant of evaluating the mathematical expectation of the time the terminal serves one loading and unloading operation.
 It was found that using the least squares method, it is possible to identify the value of the variance of the time of the loading and unloading operation, which, in turn, can be used as a point estimate when compiling the confidence interval for the mathematical expectation of this interval.
