Abstract

The task of optimization (minimizations) of amount of sensors of the mobile measuring systems (MIS) for checking of quality of pumpings units and mine lifting complex system with the use of Bayesian approach was put and resolved in article.
The non-standard approach is offered for the choice of optimum composition of the mobile measuring system for pumpings units and mine liftings complexes on the basis of technologies, used in space industry. The task of control of quality of PU(MLC) of MVS is untied consistently on the different levels of PU(MLC), that is why appears expedient in space of control (supervisions) results Х to select the area of Xn+1, as such, that at a hit for it a control result is not fixed, and MVS of control of quality of PU(MLC) passes to deep control of parameters of PU(MLC). This decision allows more exactly to get the results of measuring of the mobile measuring system for the downhole pumping units and mine complex which іmproves metrology exactness and promotes authenticity of the got information. Optimization of composition of the mobile measuring system must be conducted on the base of "task of Elfing" (TE). In MVS for the construction of algorithm of filtration of TE a least-squares method is utillized. When both dependences of initial and eventual time of measuring show by itself strict inequalities, concentrating all of measurings on both ends of interval, will purchase the optimum value of dispersion at simultaneous determination of velocity estimation. At the optimum distributing of measurings in MVS, them the incurrence of n must be broken on two even groups, placed with a maximal closeness on the edges of the measured interval of T.When in MVS it is necessary to promote exactness of estimation of a few scalar parameters of PU(MLC)), to each of them the optimum composition of MVS. It must answer and it is desirable to take into account dependence of maximum values of the module of coefficient of correlation raising of TE between two measurings from the interval of time which divides these measuring .For choice of universal composition of MVS it is necessary to conduct after the universal criterion of V. G. Ershov. During the planning of measuring experiment, that has for an object determination of parameters of the state of real PU(MLC), it is necessary above all things to define the proper system of assumptions about character of errors of information and choose on the basis of these assumptions optimum strategy of leadthrough and treatment of measurings of MVS it follows to conduct a posteriori verification of rightness of the accepted assumptions.
