Risk concept

Risk is usually understood as a probabilistic measure of the occurrence of dangerous man-made or natural phenomena, as well as a characteristic of the amount of social, economic, environmental and other types of damage and harm caused. In other words, risk should be understood as the expected frequency or probability of occurrence of hazards of a certain class, or the amount of possible damage (loss, harm) from an undesirable event, or some combination of these values. The use of the concept of risk allows us to transfer danger into the category of measurable categories. Risk is, in fact, a measure of danger.

Dangers in GA

Emergence dangerous situations is the result of the manifestation of a certain set of risk factors generated by certain sources, circumstances, conditions. In relation to the problem of safety of civil engineering activities, such events can be: deterioration under the influence unfavorable factors flight health or death of a person (user of air transport services), significant damage or destruction of an aircraft, pollution or destruction of the ecological system caused by factors of civil aviation activities, material damage from realized dangers or increased safety costs.

Risk objects

Each undesirable event can occur in relation to a specific victim - an object of risk. The connection between risk objects and undesirable events allows us to distinguish between individual, technical, environmental, social and economic risks. Each type of risk has characteristic sources of occurrence.

Types of risk

Individual risk

Individual risk is determined by the likelihood of potential hazards occurring when dangerous situations arise. It can be assessed by the number of events that caused harm to the life and health of people as a result of the manifestation of a certain risk factor: Ri=P(t)/L(f) where Ri is the individual risk; P is the number of victims (dead) per unit of time t from a certain risk factor f; L is the number of people exposed to the corresponding risk factor f per unit of time t.

continuation

An individual risk can be voluntary if it is caused by a person’s activities on a voluntary basis, and forced if a person is exposed to risk as part of a part of society (for example, using potentially dangerous transport services).

Technical risk

Technical risk is a comprehensive indicator of the reliability of technosphere elements. It expresses the probability of an accident or catastrophe during the operation of machines, mechanisms, implementation technological processes: where Rt - technical risk; T - number of incidents due to equipment failures per unit time t at identical technical systems ah and objects; T is the number of identical technical systems and objects subject to general factor risk f.

Environmental risk

Environmental risk expresses the likelihood of an environmental disaster, catastrophe, disruption of further normal functioning and the existence of ecological systems and objects as a result of anthropogenic interference in natural environment or natural disaster. Undesirable environmental risk events can manifest themselves both directly in intervention zones and beyond:

where RO - environmental risk; O is the number of man-made environmental disasters and natural disasters per unit of time t; O is the number of potential sources of environmental destruction in the territory under consideration.

Social risk

Social risk characterizes the scale and severity of the negative consequences of various types of phenomena and transformations that reduce people’s quality of life. Essentially, it is a risk to a group or community of people. It can be assessed, for example, by the dynamics of mortality calculated per 1000 people of the corresponding group: where RC is social risk; C1 is the number of deaths per unit of time t (mortality) in the study group at the beginning of the observation period, for example, before the development of negative social events; C2 - mortality in the same group of people at the end of the observation period; L is the total number of the study group.

Inherent in only one country (one company).

They are an external risk in relation to the company’s activities, because caused by external factors and does not depend on the characteristics of the company’s activities.

Feature of the risk: the company cannot influence it, but is only able to deal with its consequences (exception: if the company can lobby with its interests in the government or are themselves represented by the government).

Types of risks:

    risk of changes in industry legislation;

    the risk of introducing restrictions on import-export operations;

    rice changes in the customs system and customs legislation;

    risk of protectionism;

    risk of changes in labor legislation;

    changes in income tax rates;

    risk of changes in basic tax rates (UST, UTII, personal income tax);

    the risk of changes in the system of providing tax preferences and deductions.

Risk can be quantified. To work with it, you need to know the legislation and have qualified workers.

Technical and technological risks

Presented:

    technical;

    technological.

Refers to internal risks.

Technical risk – risk caused by disruptions in the organization of production, technological disasters and changes in production intensity.

Technical risk is expressed:

    in sudden stops in production;

    in equipment failures and breakdowns;

    failure to achieve the desired parameters of the organization’s activities at a significant level of technology;

    in the interaction of technology with existing technical means.

Its feature– is not capable of covering losses through the depreciation fund; does not lead to losses; may be due to human factors.

Technological risk – is associated with the characteristics of the technologies used by companies.

Types of risk:

      Imperfect technologies that accelerate wear and tear of technical equipment;

      Technology does not give the company any competitive advantage;

      Obsolescence of technologies;

      The risk of losing technological advantage as a result of the activities of competitors;

      Incompatibility of technology, or its inapplicability when the scale of the organization’s activities changes;

      The technology can be effective if it does not comply with legislation and product quality requirements;

Evaluation methods:

    all qualitative methods of technological risks;

    assessment method accompanied by documentation.

Risks associated with the human factor

All risks that can influence human behavior or are caused by it have an impact on the decision-making process and can influence the interests of participants in the activity (extracting interests).

Types of risks:

    Behavioral risks;

    Risk of conflicts;

    Risk of disloyalty;

    Risk of incompetence and unprofessionalism.

Behavioral risks

They arise in the process of the organization’s activities, caused by the interaction between risk subjects, having a subjective nature and aimed at changing human behavior.

Its subjects are:

    All employees of the organization, including company management;

    Third-party specialists operating on contractual terms;

    Third parties having an interest in the company’s activities;

    Owners of the organization;

    Government agencies and other regulatory agencies.

Peculiarity:

        Unpredictable;

        The consequences of their impact cannot be assessed in advance;

        Difficult to identify;

        It is impossible to regulate within the limits of manifestation;

        They are subjective.

Factors causing behavioral risk:

          Psychological characteristics of a particular person (related to the person’s temperament, etc.);

          Dissatisfaction with the work (conditions), level of payment, as well as the moral and psychological climate in the team;

          Ineffective management of the organization and personnel in particular.

Difficulties in managing behavioral risk:

    Impossibility of accounting mental characteristics every employee of the organization;

    The person making the decision may be too distant from the team in which this decision is being implemented;

    Personal benefit of participants in economic activities;

    Impact of competitors (3rd party influence).

Evaluation methods:

    psychological;

    all are high quality.

Behavioral risk can become catastrophic and lead to bankruptcy of an organization.

Let's look at some of the primary risks given in the classification scheme of business risks, which is presented in Fig. 3.4.

Technical and technological risks. One of the most dangerous, in terms of the degree of influence on the final results entrepreneurial activity The components of entrepreneurial risk are technical and technological risks. Their effect is manifested in causing damage to the enterprise (firm) due to disruption of normal operations production process as a result of failures of machinery and equipment, and in the most severe cases - the occurrence emergency situations. This can happen as a result of an explosion, fire, breakdown of machinery and equipment, etc.

Reasons similar manifestations may be - wear and tear of buildings, machinery and equipment, errors in design and installation, personnel errors, damage to equipment during construction and repair work etc. Here we do not consider the action of natural forces and malicious actions, which relate respectively to natural-climatic and criminal-legal risks, as causes.

It should be noted here that damage from technical and technological risks manifests itself not only in damage or loss of production equipment, transport and buildings, but also in stopping production and reducing or stopping the volume of products produced. In the most severe cases, a significant part of the costs is the onset of civil liability for damage. environment, enterprise personnel, as well as third parties. At the same time, material losses to society from accidents and disasters are steadily increasing.

The following examples of manifestations of technical and technological risks in different countries And various industries, as well as the losses caused by them.

1974, Flixborough (UK). Explosion of a cyclohexane cloud at a polyethylene production plant: complete destruction plant, 28 dead, more than 400 wounded.

Losses amounted to about 200 million US dollars in modern prices.

1984, Bhopal (India). Toxic gas leak at pesticide plant: 2,300 dead, 20,000 injured.

US$470 million was paid in compensation.

1985, Chernobyl (Ukraine). Accident on nuclear power plant: an area inhabited by 6.5 million people is infected.

According to Belarusian scientists, losses reach 700 billion rubles. in 1992 prices (according to foreign experts, they amount to 100–150 billion US dollars).

1988 Piper Alpha (North Sea). Explosion and destruction of a drilling platform on the North Sea shelf: 167 dead.

Losses – 1200 million US dollars. The platform was insured for $800 million.


These examples could be continued. But, in our opinion, they convincingly confirm the conclusion that, characteristic of the twentieth century, accelerated growth and an increase in the scale of material production and consumption, active use natural resources sharply increased the number and scale of industrial accidents and disasters. Therefore, issues of ensuring the safe operation of technical facilities come to the fore.

IN recent years In the world, two concepts of risk and security have become most widespread - the concept of absolute safety (As Low As Practically Achievable) and the concept of acceptable risk (As Low As Reasonably Achievable).

At the same time, as practice has shown, at present the concept of absolute security has become inadequate to the internal laws of the technosphere. Zero probability of an accident is achieved only in systems devoid of stored energy, chemically and biologically active ingredients. At other facilities (the majority of them), accidents are still possible. That is, as noted earlier, despite the measures taken by society aimed at reducing the likelihood of industrial accidents and disasters and reducing the amount of damage they cause, the random events that cause them remain possible, they cannot be eliminated by the most expensive engineering measures.

Analysis of the effectiveness of capital investments shows that in many cases it is possible to reduce negative consequences the onset of technical and technological risk if more attention is paid to actions in the event of an accident. Because even the most advanced technical systems for preventing it still do not provide absolute guarantees.

In conclusion, it should be noted that in the constructed scheme for classifying business risk, technical and technological risk is considered as simple - one that currently cannot be further divided. This situation is a significant simplification of reality. Thus, the composition of technical and technological risks should include environmental risks in their narrow sense, when, as a result of man-made factors that led to harm to the environment, a business entity not only incurs losses, but at the same time is the main bearer of potential danger and civil liability. At the same time, the above analysis and examples indicate that risk factors are fires, explosions, breakdowns of mechanisms and equipment, transport accidents, etc. Here, for example, difficulties arise with the name of individual risks, in particular, the fulfillment of the previously discussed requirement, so that the adjective to the word “risk” answers the question “what risk?” The lack of agreement among experts regarding the name, definition and content of the corresponding risks does not allow us to consider technical and technological risks as composite ones. This can only be done if the opinions of experts on these issues are agreed upon in the future.

Natural and climatic risks associated with the manifestation of elemental forces of nature. These, as you know, include earthquakes, floods, storms, storms, hurricanes, as well as other unpleasant natural phenomena such as frost, ice, hail, thunderstorm, drought, etc. These natural phenomena can have a serious negative impact on the results of business activities, become a source of unexpected costs.

Natural and climatic risks refer to force majeure circumstances – force majeure circumstances that cannot be prevented or eliminated by any measures. Since the occurrence of force majeure circumstances does not depend on the will of the entrepreneur, in accordance with Art. 79 of the UN Convention on Sales Contracts, the parties are released from liability under contracts in the event of force majeure.

Compensation for losses caused by force majeure is carried out, as a rule, by insuring transactions in specialized insurance companies.

The concept of “force majeure risks” is widely used in the literature, which is one of the ways to divide or group risks. Here, a sign of division is the ability of the entrepreneur to prevent or eliminate the causes causing the occurrence of risk events. Since force majeure by definition includes natural disasters ( natural disasters), floods, earthquakes, storms and other climatic disasters, wars of revolution, coups, strikes, etc., which interfere with business activities, this group may also include country, social and other risks.

It should be noted that, as in the case of technical and technological risk, natural and climatic risk is also considered as simple, which is also a simplification of reality. The reasons here are the same - the lack of consistency in the opinions of specialists regarding the name, definition and content of the corresponding risks. Consideration of this risk as a composite one can also be carried out subject to further agreement on the opinions of specialists on these issues.

Country risk. Country risks are directly related to the internationalization of business activities. They are relevant for all participants foreign economic activity and depend on the political and economic stability of importing and exporting countries.

Country risk may be caused by instability state power, peculiarities government structure and legislation, ineffective economic policies pursued by the government, ethnic and regional problems, sharp polarization of interests of various social groups in the state, etc.

The results of business activities may be influenced by government-sponsored trade and currency regulation, quotas, licensing, changes customs duties etc.

Currently, there are a number of organizations that, based on systematized and clearly standardized principles, techniques and operations (methods), regularly analyze the level of country risk.

The most well-known systems for assessing country risk include the ratings of Institutional Investor, Business Environment Risk Index (BERI), Euromoney.

One of the recommended ways to analyze the level of country risk is the BERI index. Its determination is carried out by about 100 experts, who, four times a year, with the help of various methods expert assessments carry out an analysis that allows you to get an idea of ​​all aspects of the political and economic situation in the country - partners in foreign economic activity.

The BERI rating evaluates political stability, attitude towards foreign investment, nationalization, devaluation, balance of payments, economic growth rates, expenditures on wages, labor productivity, infrastructure, short- and long-term lending conditions, etc.

Such analysis is carried out regularly, twice a year, by Euromoney magazine. The analyzed private indicators include:

Economic efficiency, calculated based on the projected average annual change in the state’s GNP;

Level of political risk;

The level of debt, calculated according to World Bank data, taking into account the size of the debt, the quality of its servicing, the volume of exports, the balance of foreign trade turnover, etc.;

Availability of bank loans;

Availability of short-term financing;

Availability of long-term loan capital;

The country's creditworthiness level;

The amount of outstanding obligations to repay external debt.

Thus, all aspects of the political and economic situation in the partner country are analyzed.

The results of the analysis are presented in the form of a database characterizing the assessment of the degree of investment risk and the reliability of business relations of various countries, presented in the form of a ranked list of countries with integral point and partial risk assessments.

A fragment of the corresponding database as of March 2004 is given in Table. 3.1 (www. euromoney.com).

As can be seen from this table, Russia has made significant progress in the ranking investment attractiveness and reliability of business connections. During the period from March 2000 to March 2004, its position changed from 133rd to 66th place. This progress will be even more noticeable compared to September 1999, when Russia occupied 159th place in the list of 188 countries.

For long period there is no tangible progress in the ranking of investment attractiveness and reliability of business relations of most member states former USSR. As the analysis shows, compared to 1993, Ukraine, Turkmenistan, Armenia, Moldova, Belarus, Georgia and Uzbekistan only slightly improved their positions. Have gotten worse

Features of risks of power supply disruptions in Russia. Management Connectedness of heat and electricity supply Limited substitution of heat supply and electricity supply for heating Extreme cold weather and its unpredictability Insufficiency local funds backup of life support and systems for the safe completion of technological processes Non-distribution of responsibility for safety in the event of disruptions Reducing the degree of dependence of life support on centralized energy supply: Preparation of technical regulations on safety in the event of disruptions in energy supply. Development and use of local (backup) sources. Application of systems for safe completion of technological processes. Advance development of action plans and creation of headquarters for actions in emergency situations. Creation of risk monitoring systems and early warning of threats. Dissemination of knowledge about individual and group actions, methods of survival in extreme conditions.


The need to monitor RTN and RTL is due to the aging of equipment, the disruption of continuity of operation when changing generations (not transfer of experience), the increase in the targeting of responsibility, the change in the modes of generation and transmission of electricity, the implementation of energy supply to regions by many entities, the complication of technical devices and technologies Discrepancy in the dynamics of reform, processing of the regulatory and technical framework for the design and operation of energy facilities, training and retraining of personnel.

TO technological risks include errors in measurements, calculations and (or) accounting, violation of deadlines for submitting information, failures in software, loss of the database, as well as any other violation of technological conditions related to the performance by CMO of its services under the contract (agreement). Let's consider the following classification.

Operational risks arise due to imperfect organization of processes, personnel errors, and unfavorable external events.

Technical risks are the consequences of technical malfunctions, poor-quality repairs, physical and moral wear and tear of equipment.

Business continuity risks are caused by violations of the normal execution of ECM business processes during such a period of time when there is a possibility of its non-compliance with the technological conditions of the contract (agreement). These risks require special study and cannot be predicted from the results of the activities of Russian CMOs due to the lack of representativeness of the available information.

Operational and technical risks are associated with the use of measuring and information systems. In this case, the so-called “scale effect” is observed, when specific difficulties arise when integrating a number of local relatively simple systems V complex system. Creating powerful IT support for the activities of CMOs and connecting more and more new AIIS CUEs to databases entails the risks of the emergence of new effects that could not be foreseen when designing the information system.

The risk of liquidation of the OKU due to improper performance of the functions of the main activity

It can be realized due to miscalculations in the organization of EMOs, gross errors in operational activities, as well as in the absence of an adequate response to changes in market rules. An unfavorable event in the area of ​​the main types of CMO business cannot happen instantly, therefore, with proper work with customers, the risk is easily manageable. However, constant monitoring is required here external environment(legislation, economic situation in the country, progress of electricity reform) and the quality of services provided.

Risk management system

It is advisable to build EMO risk management on an integrated basis. It should include the following controls:

Wednesday internal control– increasing employee awareness of risk management and control systems. The internal control system must become part of the corporate culture;

identification of risks and control objectives – timely detection risks, distribution of powers to manage them and establishment of clear control objectives;

information and awareness – obtaining timely, reliable and adequate information on risks. Control information must be transferred to predetermined recipients from among management;

internal control procedures – procedures that ensure complete and accurate accounting of transactions, compliance with the requirements of laws and regulations, reliability of data processing and integrity of information;

monitoring and adjustment

– identifying changes in external and internal operating conditions that require appropriate modifications of internal control procedures, identifying deficiencies and making adjustments.

When determining the effectiveness of the internal control system, it is necessary to take into account specific methods and technology, the number of inspections performed or errors identified, and the actions (or inaction) of management and owners of EMOs aimed at introducing internal control into all business processes, timely assessment of risks and the effectiveness of control measures used to mitigate their impact.

To build a risk management system, it is advisable to use a set of measures that includes the following main components.

1. Formation of a risk management policy at the level of the board of directors with determination of risk tolerance in the main areas of activity of the CMO, associated with the management hierarchy and company resources.

2. Typology, identification and ranking of risk groups in the main areas of activity at the top management level

3. Assessment of the main risk groups and determination of risk management methods (avoidance, compensation, minimization, etc.) at the level of executive management.

4. Formation of integrated maps of powers and responsibilities for risk management throughout the management hierarchy and various functional divisions of the company.

provision to sales, network and generating companies special conditions when providing services;

implementation of only economically feasible investment projects on the development of AIIS KUE and IT support;

implementation of measures to reduce costs in the provision of services;

creation of a personnel recruitment system with several stages of testing, interviews and other activities that will allow the most trained specialists with work experience and the necessary skills to be hired at the EMO;

creation of a system for training employees, improving their qualifications, and annual certification;

introduction of modern information support on electricity metering based on advanced IT solutions;

change tracking regulatory framework and prompt changes in work patterns with customers;

development effective system regulatory documentation, including provisions on divisions, job descriptions, operating regulations indicating the tasks, functions and responsibilities of managers for the timeliness and correctness of decision-making to minimize risks in their area of ​​competence;

expansion of the client base (grid organizations, power supply companies, civil companies, NP "ATS", SO and companies providing heat, water and gas supply);

expansion of the range of services offered (commercial metering of gas, water, thermal energy, communication services)
