to make certain decisions of administrative character, as well as to predict the likely outcome of the preliminary, the person entrusted with the decision, often faced with a significant number of interdependent elements, the system which is quite complicated.
analysis should be subjected to the available resources, expected results and planned objectives.In the case when the economic elements are reduced to numbers (monetary, quantitative terms, but also the weight and time), it appears that human capabilities are in direct proportion to the measured factors.
If you built a model of probability does not work well, it means that the omitted important details while making various assumptions.Thus, the social sciences blamed for the negative results in the politicians, to the weakness of human nature, as well as other factors that are regarded as temporary misunderstandings.However, they are the fundamental elements that need to be weighed to obtain reliable results.
In today's society there are a large number of informational technologies, the use of which allows maximum ease our lives and to help in case of problems related to the adoption of specific solutions in various fields.One of the most common systems currently in the approval is the purpose of the method of analysis of hierarchies.It was designed T.Saati - American scientists.
Hierarchy called a certain kind of system that is based on the assumption that its members are able to produce the formation of sets with an unrelated character.The components of each sector are influenced by members belonging to a particular sector, thus it has an impact on other groups.Analytic hierarchy allows independent elements in each level and is made in the following diagram:
- the distribution of the existing problems in the selection, which is a network or a hierarchy;
- prioritization, evaluation and criteria for all alternative solutions;
- the importance of the calculation of coefficients applied to the elements at all levels, taking into account the consistency of judgments;
- counting the weight of the combined ratio and determine the best solutions.
Analytic hierarchy as its key objective assessment brings a higher level, taking into account the interaction of different levels.Direct dependence of elements not taken into account.Currently the construction of a system of hierarchical levels appear in different sciences.The problem is broken down into the most simple components, which allows a greater reliability to handle consistent action people take certain decisions.
hierarchy analysis method, an example of which is to analyze the production cycle can be described as a grouping of employees at work, artists, managers and so on, provide a linear subordination.
Sometimes the upper level may be in a subordinate position, providing at the same time and a certain influence.Such an example hierarchy is nonlinear.The method of analysis of this type in the simplest form, is based from the very top, passing through the intermediate criteria for most of the lower level.It is a complex alternatives.
method of hierarchy analysis suggests the next stage:
- finding problems;
- construction of the hierarchy that is split tasks into individual components;
- certain weight alternatives;
- assess the priority of each item available;
- check consistency between the priorities;
- solution.
