ASSESSMENT OF QUALITY OF SERVICE IN BANK OFFICES BY METHODS OF
THE THEORY OF MASS SERVICE
In work the assessment of quality of
service is given in bank offices by methods of the theory of
mass service on the basis of which the comparative analysis
of real indicators of functioning of branches of the bank is
made. Offers on increase in efficiency of service of the
lagging behind offices are formulated, the developed
scenarios of further possible strengthening and development
of overall performance of all branches of the bank are step
by step considered.

A
NEW BATHTUB SHAPED FAILURE RATE MODEL
In this paper, we introduce a new
Bathtub shaped failure rate model named as x-Exponantial
Model and present a comparative study with Generalized
Lindley, Generalized Gamma and Exponentiated Weibull
distributions.

ABOUT OPTIMIZING OF LINES AND NETWORKS MAINTENANCE
The result of analysis of the issue
having been done, there have been proposed the strategy and
mathematical model of optimization of extended object
maintenance characterized by the extent of resource recovery
depth during the repair of lines and networks. The proposed
mathematical model of maintenance optimization would allow
to determine the optimal frequency of preventive capital
repairs and replacement of lines and networks, as well as
the optimal number of overhauls during the service life of
extended objects at the given depth of resource recovery.

ON
'SAFETY' AND 'SECURITY' TERMS AND THEIR RELATIONSHIP
The paper deals with such notions as
object safety, subject security, production safety,
environmental safety, energy security, and national
security. Issues of ensuring the subject security are not
limited by problems to be investigated in conjunction with
the issues of ensuring the object safety. Considered are the
relations between object safety, subject security,
production safety, environmental safety, energy security,
and national security issues. National security problem
includes all the listed above safety/security issues.

EFFICIENCY ASSESSMENT OF
THE MAIN EQUIPMENT OF ELECTRIC POWER SYSTEMS
The paper deals with the issues related
to efficiency of the main equipment of electric power
systems (EPS). An efficiency indicator has been selected
that takes into account relationships between efficiency,
economic component, technological advance and reliability.
We show the possibility for pilot test (or validation) of
the efficiency indicator, and for comparison of the main EPS
equipment with account of its efficiency.

NUMBER OF CALLS IN A
CYCLIC-WAITING SYSTEM...
A single-server cyclic-waiting system,
i.e. a queuing system, in which a call gets service either
at the time of arrival or after some cycle time T, has been
studied in the article. The distribution functions of the
intervals between arrivals and service times have
exponential form; the service discipline is FCFS. Analytical
results for the mean number of calls in the system are
indicated. Numerical and graphical results have been given.
