The article provides an example evaluation of the technical condition of building and handling machines in terms of corrosion resistance. Using functional method of determining the weights estimated sufficiency compositions anticorrosion treatment building and handling machines.

Keywords: The sufficiency condition, the generalized criterion, a metric multiplicative convolution operator on the set of individual criteria

This article describes an algorithm for finding the linear functional quality that describes the order of preference on a set of technical systems. The basic idea, which implements the algorithm is to break the complex solutions of the preference (for many variables) into a number of simple solutions (in pairs of variables), followed by a formal synthesis of the overall solution.

Keywords: The algorithm for finding the linear functional quality of the order of preference on a set of technical systems, formal synthesis, the numerical value of the degree of competence of the individual experts

The article describes one of the possible approaches to the investigation of a technique of definition of quality indicators of vehicles and lifting-transport machines, examines the concept - combining numerical estimate of single and complex indices into a single composite index.
The following algorithms: the algorithm of finding the functional quality systems, represented by the linear form, with varying competence of experts, the algorithm modified method, allowing to make the transition from бифакторного distribution to мультифакторному, which is important when processing expert information; algorithm modified method, characterized by greater commonality and expanding the use of standard computer programmes at the decision of problems of estimation of quality systems on a computer.
