From this it follows that AAS will generate nonrandom two-element piecewise linear rules if each of divided classes is presented by not less than 23 objects at K = 2 and not less than 56 at K = 5.

5 Risk Management

Risk management is the main, final stage in risk analysis on which priority areas and optimum security aids are defined. Main questions considered at this stage are establishment of importance of the considered risk, comparison of costs for its reduction with those benefits which can be received as a result of it and support in carrying out policy of risk reduction. At this stage it is possible to receive the answer to a question of what risk level is excessively big and therefore demands creation for its technical systems decrease and what security systems from the point of view of material inputs are the most effective.

At first sight it can seem that the task of risk management is extremely clear and is in reducing risks from each technological unit to unified minimum or even just “zero” level. However, all researches in this area show that it is unreasonable to want to reduce risk from various technological units, for example, such as coal industry or nuclear power plants, or even in each concrete unit to one level.

The task of risk management can be brought to that on the basis of some certain criteria to answer a question of what means and to what level it is necessary to reduce risk in this or that field of production activity. One of possible and the most widely developed tool of the solution of this task is the assessment of efficiency of costs for risk reduction.

The analysis of efficiency of costs for risk reduction is directed to the solution of tasks connected with application of these or those measures and security systems. Therefore, it has to be applied preferably at a design stage of development and provide conditions for the choice of the most optimum actions for increase in safety both during normal work of the enterprise, and in emergencies.

As it has been already told earlier one of the main tasks of the stage of risk determination is in this fact that those criteria and corresponding methods which would allow to answer the question what is to consider dangerous and what is—safe. Especially sharply these questions rise for existing and again created difficult technical systems connected with use and production of large amounts of energy and dangerous substances where accidents can lead to environmental disasters. The similar situation is observed when a natural control system of safety is provided solution of problems which it never solved and, perhaps, isn’t capable to solve, for example, on utilization of outlying to nature chemical compounds, large quantity of fusible substances, etc.

Considering this, it is necessary to use existing current regulations and to develop new ones for safety or more likely the rules of risk management which have to be based on determined criteria and norms.

Every day all people are affected by different types of danger.
