RECOMMENDATIONS GENERALIZATION FOR IMPROVING THE METHODOLOGY OF SUBSTANTIATION OF REQUIREMENTS FOR THE VALUES OF QUANTITATIVE INDICATORS OF ARMAMENT AND MILITARY EQUIPMENT UNIFICATION

Abstract

Establishing the optimal values of quantitative indicators of the level of unification for armaments and military equipment (AME) samples during the elaborating of technical development requirements (TDR) for research and development work (R&D) on their creation (modernization) is still an urgent task, as they (values) directly affect technical and economical evaluation of AME samples.
 It is stipulated in the normative documents that quantitative indicators of the unification level of the sample are determined by the factors of applicability and repeatability of the standard sizes of assembly units and parts of the sample. In addition, the formulas for their calculation are also specified in these documents. It makes possible to assess only the actually achieved level of unification, while the question of a methodological approach to establishing the values of indicators in the requirements of the TDR remains open.
 In previous studies, the author has consistently developed recommendations for establishing optimal values of quantitative indicators of the level of unification for AME samples. This paper summarizes the recommendations on the method of substantiation of requirements for the values of quantitative indicators of AME unification.
 The author proposes to replace the factor of repeatability with a relative factor of repeatability, which allows determining the indicators in single units (in percent) and, accordingly, applying a single method of their establishment.
 The proposed general methodological approach to substantiation of quantitative indicators of the unification level consists of four stages:
 
 determination of the basic level of quantitative indicators of the unification level;
 determination of the list of factors that affect the level of unification, differentiation of factors by the nature of the impact and determining the rating of their significance;
 determination of coefficients of factors that influence the unification level;
 calculation of quantitative indicators of the unification
 
 The paper provides a clear algorithm and recommendations for sequential execution of stages.
 Taking into account the positive results of previous studies, generalized recommendations for improving the methodology of substantiation of requirements for the values of quantitative indicators of unification were developed. These recommendations can be practically applied in the process of setting requirements in the TDR for R&D on the development of AME samples.
