GENERAL PRINCIPLES OF ASSESSMENT OF STAFF SKILLS BUILDING SPECIALTIES

Nowadays the culture of controlling and estimating quality becoming more and more important. Estimating – is a process of gathering and processing information, which provides to members of education process opportunity to make decisions, which could help to improve quality of work. Database of estimating is bunch of governmental standards, control and estimating of efficiency systems are tests. Last 10-15 years the usage of tests is growing all over the world, that is why many companies and governmental structures appeared, which are creating new tests, promoting them, organizing mass testing and all-time mining the information, to understand the quality of education. Western countries are way far from our quality of testing of new scientific personnel, by the level of testing methods development, by the technical support of development processes, the use, handling and storage for tests. Last year’s our scientists see the positive trends in this field. Strategy and tactics of controlling systems improvement. Education testing zooming and governmental standards developing are generating new problems, prerequisites and requirements, which are aimed on controlling systems perfection and trainees’ preparation quality estimating, the process itself estimating and its efficiency by immediate response on the environment

COMPONENT SUPPLY MODEL FOR REPAIR ACTIVITIES NETWORK UNDER CONDITIONS OF PROBABILISTIC INDEFINITENESS.

This article contains the systematization of the major production functions of repair activities network and the list of planning and control functions, which are described in the form of business processes (BP). Simulation model for analysis of the delivery effectiveness of components under conditions of probabilistic uncertainty was proposed. It has been shown that a significant portion of the total number of business processes is represented by the management and planning of the parts and components movement. Questions of construction of experimental design techniques on the simulation model in the conditions of non-stationarity were considered

MANAGEMENT PROCEDURE OF SUPPLIES OF UNITS, MATERIALS AND CONSTITUENT PARTS FOR REPAIR AND MAINTENANCE SUPPORT OF TRANSPORT AND PRODUCTION MACHINES

This article considers a question of creation of schemes and sequence of passing of the main stages of process of execution of repair and maintenance works order taking into account formation of stocks of necessary spare parts, materials and constituent parts. Models of an input stream are offered for inventory control system, which are rather adequately described by autoregressive models of order two

EVALUATION OF THE FREQUENCY OF DIAGNOSTICS OF COMPONENTS AND ASSEMBLIES FOR TRANSPORT AND TECHNOLOGICAL MACHINES ON THE BASIS OF HIDDEN MARKOV CHAINS

In this article a statistical analysis of supply volumes of spare parts, components and accessories was carried out, with some persistent patterns and laws of distribution of failures of major components revealed. There are suggested evaluation models of components and assemblies reliability for the formation of order management procedures of spare parts, components and accessories for the maintenance and repair of transport and technological machines. For the purpose of identification of components operational condition there is proposed a model of hidden Markov chain which allows to classify the condition by indirect evidence, based on the collected statistics
