The dissertation text consists of three parts: dissertation introduction, main body and conclusion, each of which carries its meaning.
So, if the main part of the thesis describes the entire course of study, from analysis of the issues under examination before the practical application of ideas of the author, in conclusion we describe the results obtained by the author, and recommendations for their use, and then in the dissertation introduction there are all essential characteristics of the research.
These fundamental characteristics must be fully qualified to describe the author as a researcher who is ready to pose and solve scientific problems that have scientific and practical value.
The volume of the dissertation introduction is usually 5-6 pages, which must contain:
-Relevance
-The purpose and objectives of the study
-Object and subject of study
-Hypothesis or main idea of study
-Methodology and research methods
-Scientific innovation
-Scientific positions for the defense, and their reliability
-And practical (economic, social) significance of the results
-Testing results
It should be emphasized that all the characteristics of the work should be associated with the theme of the work.
Relevance of the research is a characteristic of modern states in the researched topic of the thesis, it describes the author as a researcher, able to independently demonstrate and articulate the essence of the investigated problem and its practical importance for the industries of our country. Relevance is the basis for formulating goals and objectives and consistency in their decisions. It first gives a brief description of industry, for which you try to solve scientific problems.
Thus, as a result of the analysis of the relevance of the theme determined by the object and the subject of study, and the wording of the object and the subject of research should be consonant with the theme of the thesis. In the dissertation introduction the researchers should be grouped considering their opinions on the subject. And the author should state the need for a further scientific research in this direction.
The next stage of work is the formulation of goals and objectives of the study.
The aim of the thesis almost repeats the name of the research with the addition at the beginning of the phrase: "to develop ..", or at the end of the phrase: "providing efficient ..." etc.

In formulating the tasks use such turnovers: “discover the essence”, “to formulate and justify”, “identify the factors”, “consider”, “analyze”, “explore”, “develop”, “to define the place”. In addition, it must be remembered that the problems stated above define the name and content of the main chapters and sections of the dissertation.
