The problems of efficient use of energy costs have been actively explored in recent decades in connection with rising energy prices. During this period, the main models for assessing energy efficiency and energy management were developed, including the models Total Quality Management, Six Sigma and Sustainable Value Stream Mapping. The aim of the research was to study the energy efficiency of the production and services in Kazakhstan based on materials of the large-scale national study on the estimation of production and transaction costs by these methodologies. To assess the data obtained, a statistical analysis of the dependence on the indicators of variation and ranking was used. Electricity costs are among the leading manufacturing costs and affect management models. However, according to the maturity model of energy management, energy efficiency in Kazakhstan is low. Despite the government’s declarations of effective energy policies, the administrative burden for businesses remains high, and legislation does not stimulate a reduction in energy costs.
Ecosystem business models are becoming widespread in the modern economy; their potential is increasingly understood by financial institutions. Banks become part of the ecosystems and some of them initiate their creation, seeing in this business model an opportunity for their development. However, not all the possibilities of the ecosystem business model are sufficiently recognized by banks. Meanwhile, becoming “orchestrators” of ecosystems, banks get new opportunities, taking on new management functions that require the development of new promising competencies. This aspect predetermined the goal of this article—to explore the essence and development prospects of banking ecosystems and create a model for the establishment of additional innovative and technological advantages for banking ecosystems, allowing the bank to create conditions for long-term competitive advantages. Methods of comparative analysis, statistical methods, modeling methods, and cluster and regression analysis were applied. The results: a model of technological increment that formed during the functioning of the banking ecosystem has been developed; the authors established that the orchestration of the ecosystem by the bank creates opportunities for the formation of new profit centers because of the formation’s greater number of innovative technologies and the possibility to dispose the intellectual property.
In article the problem of a choice of the optimum circuit of connection of the 'partitioned site of a contact network of a direct current to traction substation with the purpose of minimization of losses of energy in system of electro supply of passenger transport at various ways of the organization of electro supply system is considered. The diminution of power consumption by an electric carrier is one of the mains problems of a raise of effectiveness of its activity. The electrical power system an electric carrier contributes an essential share in total losses of an electrical energy. It result inserts to a drop of a common efficiency of an electrical haulage. Losses in an electrical power system increase with a diminution o f magnitude of a supply voltage. The spreading of magnitude of a supply voltage in a contact web of the street car compounds50 %. For a web of a trolley bus -40 %, subway -40 %. Level recession of a supply voltage on a current collector of a rolling stock result ins to non rational utilization of electrical energy, aggravates dynamic indexes of transport facilities. The Rotation rate of the armature shaft of the railway motor depends on magnitude of voltage nourishing a motor [l], and magnitude of a torque on a wheel rim has square association on it M = cmFXmor = cmkIiot = *(U2 -c,Fv), where v-velocity of a rolling stock; U -voltage on a current collector; ImOr -current o f the railway motor; RmDt -resistance of a chain of the railway motor; c, -permittivity of vacuum of a motor; F-torrent of a magnetic field of a motor; e, -mechanical stationary value of a motor; k -constant of proportionality between a torrent and a current of a motor. Aggravation of dynamic indexes of a rolling stock result ins to magnification of expenditures of a time on journey, to capacity reduction o f transport mains. Driving of one box rolling stock of the street car on a standard station limit at voltage on contact wire U = 550 In allows Rmo, to advance maximum velocity Vmm=33,5 kmh with a specific consumption of an electrical power on driving Aud=86,5 Wtlan. At minimum voltage in a web the velocity is reduced up to Vmin=32,5 k d h , the specific consumption of an energy increases by driving up to 94 WWtlan. For a five-wagon train of subway on a standard station limit at rated voltage Vmax=52,5 kmfl.1. At minimum -Vmin=46,5 k d h . The Specific consumption of an energy at U = 750 In is incremented with 83,5 W W t h (at Vmin) up to 85.6 W h / h (at Vmax). At voltage in 750 In and a running velocity in 46,5 kmlh the specific consumption of an energy of the same train compounds 69,5 W t k m . For a trolley bus the specific consumption of an energy and a running velocity vary slightly. Curves o f driving for a train o f subway are reduced on Fig. 1. way (0 Fig.1. Curves of driving at various meanings of a supply voltage and mean speeds of driving on a station limit Now some versions of schematics for hooking up of a thrust web to the power source use. Basic concepts are: the scheme of an one-sided, bilateral and noda...
