Mathematical modeling of a stock market functioning is one of the actual and at the same time complex task of the modern theoretical economics. From our point of view, building such mathematical models “ab initio”, by using analogy between the stock market and a certain physical system (in our work, laser), is the most promising approach. This paper proposes a simple econophysical model of stock market as an open nonequilibrium system in form of Lorenz–Haken equation. In this system, variation of ask price, variation of bid price, and instantaneous difference between numbers of agents in active and passive state are intensity of external information flow is a control parameter. This model explains the impossibility of existence of an equilibrium state of the market and shows the presence of deterministic chaos in a stock market.
This paper examines what kind of competencies the Russian hotel industry employers expect from hospitality MS graduates and compares them to the current Russian academic standards. The main data collection methods included content analysis of professional and educational standards and semi-structured interviews with hotel industry experts. The results of the study revealed that the competencies of the MS graduates were generally determined by the state educational standards. However, there was a discrepancy between the educational standards and the new professional standards applied in the hotel industry. Therefore, the need to monitor and match the educational outcomes with the industry requirements appears to be one of the main developmental problems in the Russian hotel sphere. This knowledge will help with better understanding of the complexities in the Russian hotel industry, which in turn will help Russian universities meet the hotel industry’s needs.
Development of Russian electric power industry in recent years is characterized by a multitude of problems and a decrease in a number of performance indicators. It dissatisfies consumers and encourages them to implement various measures to reduce risks and costs of energy supply. This creates preconditions for the emergence of «active» consumers in the domestic electric power industry. Given this trend it would be appropriate to switch from Supply Side Management to Demand Side Management. This will require the implementation of a wide range of measures, including strategic issues of industry development, legal framework and transition to a customer-centric market model.
A fridge plays an important role in the kitchen in comparison to other appliances because it helps to store food products at optimal conditions for a long period of time. The ordinary refrigerators perfectly allow preserving meals but they are not effective in case of food management. Providing a remote control for home appliances extends the everyday usage of these devices. In addition to the remote control device, some manufacturers use additional modules such as internal cameras and hands-free speaker for convenient control of an appliance. All these devices are able to communicate with each other to reach common goals. The home appliance producer Liebherr in cooperation with technology company Microsoft developed a solution for remote control of refrigeration with possibility of food recognition using Machine Learning algorithms. This option enables automatic compiling of the list of food stored in the fridge and food ordering in an online shop without manual actions. This opportunity enables not only a convenient usage of an appliance but also allows reduction of electricity consumption because user does not open fridge doors frequently as far as he knows a list of food in refrigerator. In this paper we describe SmartDevice technology from Liebherr that was developed for adding smart features to the brand products. In particular, we review main business processes of SmartDevice, discuss advantages and disadvantages of this solution for the end customers and identify future research for creating smart fridges.
A modern enterprise has to react to permanent changes in the business environment by transformation of its own behavior, operational practices and business processes. Such transformations may range from changes of business processes to changes of information systems used to support the business processes, changes in the underlying IT infrastructures and even in the enterprise information system as a whole. The main characteristic of changes in a turbulent business environment and, consequently, in the enterprise information system is unpredictability. Therefore, an enterprise information system should support the operational efficiency of the current business model, as well as provide the necessary level of agility to implement future unpredictable changes of requirements.
This article aims to propose a conceptual model of an agile enterprise information system, which is defined as a working system that should eliminate the largest possible number of gaps caused by external events through incremental changes of its own components. A conceptual model developed according to the socio-technical approach includes structural properties of an agile enterprise information system (actors, tasks, technology, and structure). Structural properties define its operational characteristics, i.e. measurable indicators of agility – time, costs, scope and robustness of process of change. Different ways to build such an agile system are discussed on the basis of axiomatic design theory. We propose an approach to measurement of time, cost, scope and robustness of changes which helps to make quantitative estimation of the achieved level of agility.
We consider interior and exterior initial boundary value problems for the three-dimensional
wave (d’Alembert) equation. First, we reduce a given problem to an equivalent operator
equation with respect to unknown sources deﬁned only at the boundary of the original
domain. In doing so, the Huygens’ principle enables us to obtain the operator equation
in a form that involves only ﬁnite and non-increasing pre-history of the solution in time.
Next, we discretize the resulting boundary equation and solve it eﬃciently by the method
of difference potentials (MDP). The overall numerical algorithm handles boundaries of
general shape using regular structured grids with no deterioration of accuracy. For long
simulation times it offers sub-linear complexity with respect to the grid dimension, i.e., is
asymptotically cheaper than the cost of a typical explicit scheme. In addition, our algorithm
allows one to share the computational cost between multiple similar problems. On multi-
processor (multi-core) platforms, it beneﬁts from what can be considered an effective
parallelization in time.
Researchers face fundamental challenges applying the stochastic geometry framework to analysis of terahertz (THz) communications systems. The two major problems are the principally new propagation model that now includes exponential term responsible for molecular absorption and blocking of THz radiation by the human crowd around the receiver. These phenomena change the probability density function (pdf) of the interference from a single node such that it no longer has an analytical Laplace transform (LT) preventing characterization of the aggregated interference and signal-to-interference ratio (SIR) distributions. The expected use of highly directional antennas at both transmitter and receiver adds to this problem increasing the complexity of modeling efforts. In this paper, we consider Poisson deployment of interferers in ℜ 2 and provide accurate analytical approximations for pdf of interference from a randomly chosen node for blocking and non-blocking cases. We then derive LTs of pdfs of aggregated interference and SIR. Using the Talbot’s algorithm for inverse transform we provide numerical results indicating that failure to capture atmospheric absorption, blocking or antenna directivity leads to significant modeling errors. Finally, we investigate the response of SIR densities to a wide range of system parameters highlighting the specific effects of THz communications systems. The model developed in this paper can be used as a building block for performance analysis of realistic THz network deployments providing metrics such as outage and coverage probabilities.
Opening ceremonies for new manufacturing plants are commonplace and yet, they
are surprisingly under-documented. Although these ceremonies may, at first glance,
appear to simply serve as celebrations to mark the successful completion of an industrial
project, they are based on symbolic actions, and usually very well planned
and executed. Consequently, their underlying meaning is more complex. A study of
the opening ceremonies of 56 manufacturing facilities in Russia by foreign multinationals
shows that opening ceremonies also serve to demonstrate mutual acceptance
of the differing motives of both the foreign investors and the local authorities for
building the plant. The analysis points to recommendations regarding the timing and
design of the ceremonies, as well as participants’ behavior, that can ensure that such
events contribute to the attainment of organizational goals.
What are the core strategic capabilities the domestic and multinational firms should possess to do business successfully in Russia? In this chapter, we try to answer this question with our pilot case study of six firms operating on the Russian high-tech, low-tech and services markets - three global companies, one foreign (Germany), and two Russian. Our research shows that customer orientation is the crucial strategic capability, highlighted by all of the studied firms. For multinational and high-tech players, it is followed by research and development, mentioned by two thirds of respondents. Moreover, all of the four multinational and foreign companies leverage on their strategic capabilities of cross-cultural management and general sales capabilities as their keys for success in Russia.
This article aims to identify effects of client orientation on business models of central power generation companies.
Five major Russian wholesale electricity market players were selected for the analysis conducted applying A. Osterwalder and Y. Pigneur’s ‘Business Model Canvas’. To identify the changes induced by client orientation, the progress of companies’ business models was traced over 6 years; from 2009 to 2015.
Five major trends in business model changes due to client orientation were identified:
1. Declaration of client orientation and adoption of client service standards;
2. Advent of business diversification in favor of engineering, construction, service, operation and maintenance of generating facilities;
3. Increase in vertical integration;
4. Increase in diversity of communication channels with consumers;
5. Increase in diversity of customer relationships.
The results were compared with those obtained in international studies. Conclusions about international and local character of the trends are presented.
The study contributes to knowledge of current and upcoming changes in the business of central power generation triggered by the advent of electricity prosumers. It is valuable both for management decision makers and theorists.
This article develops the concept of flexibility in HRM practices which can increase a company's potential to respond to substantial variation in the business environment. It reveals the characteristics of flexible HRM practices in Russian companies in an uncertain external and internal environment. Cranet survey data gathered from October 2014 until March 2015 is used for measuring the environmental uncertainty and flexibility of staffing, training and development, pay, employee relations and communication. A comparison of the flexibility indices for the four HRM practices show a higher level of flexibility in training and development practices. The research results confirm a direct positive relationship between the complexity of the environment and the flexibility of HRM practices.
In the 1960s, the so-called “software crisis” triggered the advent of software engineering as a discipline. The idea was to apply the engineering methods of material production to the new domain of large-scale concurrent software systems in order to make the software projects more accurate and predictable. This software engineering approach was feasible, though the methods and practices used had to differ substantially from those used in the material production. The focus of the software engineering discipline was the “serial” production of substantially large-scale, complex and high quality software systems. Researchers argue whether the crisis in software engineering is over yet. The software crisis originates from a number of factors; these are human-related and technology-related factors. To manage this crisis, the authors suggest a set of software engineering methods, which systematically optimize the lifecycles for both types of these influencing factors. This lifecycle optimization strategy includes crisis-responsive methodologies, system-level architectural patterns, informing process frameworks, and a set of knowledge transfer principles. Software development usually involves customers, developers and their management; each of these parties has different preferences and expectations. These parties often differ in their vision of the resulting product; typically, the customers focus on business value while the developers are concerned with technological aspects. Such a difference in focus often results in crises. Thus, the software crises often have a human factor-related root cause. To deal with these kind of crises, software engineers should enhance their skillset with managerial skills, such as teamwork, communications, negotiations, and risk management.
This study revisits one of the most widely used concepts in marketing - customer orientation (CO) - in the context of the Russian emerging market. Analysis of three sets of survey data, combined with insights from in-depth interviews with industry experts, suggest that customer orientation in the Russian market consists of two distinct dimensions: customer-centric strategy and customer service delivery. Both dimensions contribute to firms' ability to serve their customers, adapt to their market environment, and optimize growth and profitability. However, the relative impact of the two dimensions of CO does differ across diverse types of performance outcomes, suggesting that both are critical in a firm's quest to improve its overall business performance.
The paper provides the target model for innovative ecosystem of Russian power industry. The system is based upon the key attributes of the ecosystem, which were revealed within the theoretical part of the paper: limited state intervention, free interaction of the participants and the availability of proper infrastructure. At the same time the proposed target model provides a solution for the current problems of existing prototypes of ecosystem in the Russian power industry via integrating the key actors with the focus on delivering added value to the end user.
The importance of the problem under investigation is to find an effective way to manage the defaults occurred in case of a project which has not enough control during the process of implementation. Usually it goes to delays, and as a consequence to it in very poor quality. The purpose of the article is to provide the project with the necessary level of control by placing control points in it. The article suggests methods for determining the places and necessity for conducting inspections during the construction period of the project. The materials of the article can be used by project managers for more efficient and qualitative management, for faster completion with the lowest possible cost in the highest possible quality.
Public procurement procedures prescribed by legislation not only enhance transparency and competition but also entail certain transaction costs for both customers and suppliers. These costs are important to the efficiency of the procurement system. However, very few previous studies have focused on estimating procurement costs. This paper proposes a methodology for public procurement cost evaluation. We show how procurement costs can be calculated using a formalized survey of public customers. This methodology was tested with a representative group of public customers operating in one region of the Russian Federation. We formulate the policy implications of our study as they relate to the improvement of public procurement regulations and argue that this methodological approach can be applied in other developing and transitioning economies.
For the multiproduct EOQ-models the analysis of several vehicles deliveries feasibility factoring in vehicle capacity is conducted. It is proved that such deliveries with an increase in the number of vehicles that simultaneously used for a single delivery cannot be effective, if a discount is not given for the cost of such a delivery. The necessary and sufficient condition that sets the threshold level of the discount, at which the deliveries by several vehicles are able to compete with the traditional solutions, is established. The cases of numerical calculations are presented in the article.
The article discusses the phenomena of charitable giving and philanthropy, demonstrates differences between formal and informal volunteering, pro bono activities. The author indicates cultural differences and economic significance of volunteering, then describes what the predictors and effects of giving and volunteering are. Debates around costs, effectiveness, and social impact of giving and volunteering are also highlighted in the article.
We present our observations of electromagnetic transients associated with GW170817/GRB 170817A using optical telescopes of Chilescope observatory and Big Scanning Antenna (BSA) of Pushchino Radio Astronomy Observatory at 110 MHz. The Chilescope observatory detected an optical transient of ∼19m on the third day in the outskirts of the galaxy NGC 4993; we continued observations following its rapid decrease. We put an upper limit of 1.5 × 104 Jy on any radio source with a duration of 10–60 s, which may be associated with GW170817/GRB 170817A. The prompt gamma-ray emission consists of two distinctive components—a hard short pulse delayed by ∼2 s with respect to the LIGO signal and softer thermal pulse with T ∼ 10 keV lasting for another ∼2 s. The appearance of a thermal component at the end of the burst is unusual for short GRBs. Both the hard and the soft components do not satisfy the Amati relation, making GRB 170817A distinctively different from other short GRBs. Based on gamma-ray and optical observations, we develop a model for the prompt high-energy emission associated with GRB 170817A. The merger of two neutron stars creates an accretion torus of ∼10‑2 M ⊙, which supplies the black hole with magnetic flux and confines the Blandford–Znajek-powered jet. We associate the hard prompt spike with the quasispherical breakout of the jet from the disk wind. As the jet plows through the wind with subrelativistic velocity, it creates a radiation-dominated shock that heats the wind material to tens of kiloelectron volts, producing the soft thermal component.
