The competitiveness of any company engaged in the
wholesale or retail sale of goods and services is
substantially determined by the level of quality of the
services provided. For the accompanying business of
vertically integrated oil companies, the criterion of
quality service is not an exception. Currently, cafes
and shops at the refueling complex are not only a
convenient service for customers, but also a solid
source of additional revenues for the largest oil
companies, each of which seeks to make the retail
network attractive to customers by offering a wide
range of goods in stores, ready meals in a cafe, and
related services. To satisfy the needs of the client, it is
necessary to offer a wide, but rational assortment of
goods at the refueling complexes. The claimed goods
must always be at the refueling complexes. The lack of
goods necessary for the customer on the shelf means
the loss of sales and profits, the order and location of
goods that are not in demand - the formation of
surpluses, returns to the supplier and write-offs. This
also affects the overall economic performance of the
company. In this regard, the increase of logistics
service is one of the priority tasks of the
accompanying business of vertically integrated oil
companies
The article presents the methods of efficient monitoring rate of the mobile agricultural equipment brake system based on the usage of methods of the theory of relativity. We have considered the methods of the brake gear monitoring rate according to the acceptable level of reliability, to the technical index and change logic of the technical parameters state and economic-probabilistic method. From the above-stated one can see, first, that diagnosing usage is the development of maintenance preventive strategy. Second, its practicability and the ways of realization are determined by technical and economic calculations
Condition monitoring is a necessary element of the
transport and special machinery in agriculture. The
task of the control operations other than the
determination of the technical state of the object is to
determine the required amount of work, as well as
rational amount of collateral the repair of which could
be combined with the next maintenance. Based on the
results of processing of the information, we may
generate requests for service. In the conditions of
uncertainty of receipt of requests for servicing of
individual machines, estimated volumes and timing,
we have am appropriate development of applied
technique of justification of the number of diagnostic
posts for interactive control of a technical condition
of vehicles and special machinery in agriculture. The
presented methodology is based on probabilistic
methods, and allows the quick optimization of the
number of existing posts interactive diagnostics in the
enterprise, if necessary, translating the existing posts
in "standby" mode, or Vice versa, returning from a
reserve in "work" mode. The production and
technical base of the enterprise service based on the specific assumptions are considered as a system of
mass service (SMO), and the function of such a SMO
– as the process of mass service. The process of
queuing as applied to interactive diagnosis are
"Markov" processes "death and reproduction" with a
finite or countable number of States and continuous
time. To describe the states of the system we use the
system of the Kolmogorov equations for steady state
of "Markov" process. On their basis, we have
determined average queue length, time of stay orders
in the queue, number of busy channels and the
bandwidth of the CFR. Using the intensity of the
requests and the service time of a single application
for specific equipment, the article establishes the
efficiency of online diagnosis posts. The result of the
proposed applied methodology enables timely
decision-making about the need for reconstruction or
technical re-equipment of the company
The article describes the basic techniques for working
with Kontrol automated monitoring system. We suggest
the algorithm for creating and editing test databases,
software settings-governmental applications,
technologies used in the tests of text, graphics and
multimedia data
The article presents a review of the existing methods for the determination of crotonaldehyde in food. The necessity of this component in the control of food products, including wine, is visible because of its toxicity and the probability of formation during microbial synthesis and chemical transformations. The
article describes the developed qualitative method of determining the content of crotonaldehyde in table wines with spectrophotometry
Damage of grain and seeds by machines makes
essential negative impact on sowing qualities of seeds
and processing properties of grain. While processing of
grain a lot of various cars and actions differently injure
weevils. To exclude traumatizing of grains in the
course of mechanical preparation is not obviously
possible, as working bodies of cars are a source of
mechanical and thermomechanical damages. Besides,
injured weevils on the physical-mechanical properties
practically do not differ from whole, i.e. they do not
possess signs for machine division. To reduce
traumatizing of weevils is possible with the help of
application of optimum technologies of machining,
selection of the conforming technological modes, using
as a part of actions of constructional stuffs with a low
elastic modulus, perfection of their design data. For
definition of injuring ability of various machines and
actions through which takes place grain lots, have
developed a procedure which allows with high degree
of reliance to estimate complex traumatizing of weevils
(namely, their outside integuments and intrinsic
frames) machines and the actions which are a part of aggregates and complexes for machine preparation of
grain and seeds. The developed procedure bases on a
basis of the standard documents regulating test
methods of agricultural machinery and together with it
allows to consider connatural heterogeneity of the grain
lots arriving for processing
The article presents an analysis of the existing approach
to automobiles technical maintenance in
agriculture. We have pointed out that in modern
conditions it is impossible to forecast the automobiles
maintenance operation frequency and as a
result its improvement as well. It is obvious that
one cannot achieve the considerable increase of
maintenance operation efficiency by separate means
and there exist the necessity to treat it as a system
and use the up-to-date methods to investigate and
improve complicated systems. We have made a
conclusion that the increase of maintenance operation
efficiency is not possible without some rational
strategy of maintenance operation and repair. We
have shown that the program of maintenance operation
and repair being an integral part of automobiles
technical maintenance has considerable effect on
maintenance and repair quality. As a result, there
is some necessity of the developed system of
parameters diagnosing and control in technical
maintenance and repair. We have shown that to
get sufficient diagnose information one needs
selection of the controlled parameters which
give maximum information about the object
technical status taking into account possible characteristics
of its operational faults. We have discovered
that in order to solve the task it is necessary to
have the object’s information pattern, calculation of
possible characteristics of the controlled object being
in good or bad order due to some parts fault,
evaluation of information brought by every parameter
and determining parameters to be diagnosed. We
have proposed to evaluate the parameters’ information
value with the help of information entropy as
uncertainty measure that is one of the main concepts
of the information theory. Because of solving
the task, we have got the aggregate of the controlled
automobile parameters orderable according to the
amount of information
The article is devoted to an actual problem: increasing of reliability of expert estimates, due to attraction in group of the most competent experts for carrying out examination. The analysis of application of expert estimation in the field of operation of corporate and telecommunication networks is provided in the article. The technique of an assessment of competence of experts is offered. When assessing the competence of experts the following factors were considered: specialization of the expert, an experience and experience of its work in the field, scientific qualification, existence of scientific works on a perspective of carrying out examination. For identification of a priority of factors at determination of competence of experts it is offered to use a method of the analysis of hierarchies. The necessary number of experts for carrying out examination of objects is defined on the basis of application of the statistical analysis
