FUNCTIONAL-COST ANALYSIS OF «DSC» SYSTEM OF MOTOR VEHICLES «BMW»

Abstract

In Ukraine for the implementation of the International System of Quality ISO 9000 it is necessary that the producer uses the methods of the project solutions analysis. Both input and output data must be subject to such analysis. The enterprises which create or develop quality products must apply either standard technologies of functional-cost analysis or use their own technologies. Functional-cost analysis is aimed at provision of needed consumer properties of the object with minimal possible resources expenses at all stages of production process.

The paper considers functional-cost analysis of «DSC» system of the motor vehicles «BMW». Functional model of «DSC» system of motor vehicles «BMW» and classification of functions of its functional model is developed.

Classification of functions of the functional model of the system «DSC» of the motor vehicle «BMW» is presented. Utility factor of «DSC» system of the motor vehicle «BMW» is determined by constructing the priorities matrix according to the known calculation technique.

Aggregated expenses criterion during the design of the engineering or production systems takes into consideration expenses at all the stages of the system life cycle, for the assessment of which matrix of expenses of «DSC» system of the motor vehicles «BMW» is constructed, the expenses coefficient is determined from this matrix.

Utility diagram of «DSC» system functions of the motor vehicle «BMW», diagram of functions ranking relatively functional-cost diagram of the system, diagram of the system functions expenses, diagram of system functions ranking relatively expense ratio, diagram of the values of functional cost of the system functions index, diagram of system functions ranking relatively functional cost index have been constructed.

According to the constructed diagrams functions of «DSC» system of the motor vehicle «BMW» are determined, which have positive functional-cost index and the highest rating among the considered functions. Operations or functions which have the highest functional-cost index and rank are those operations, improvement of which leads to further development of the system or achieving the objective of the analysis.
