Description

The utility model relates to the field of data processing for special applications, in particular, for modeling and researching the process of determining the values of generalized quality indicators of information systems using regression analysis methods.

A device is known that contains blocks of two types, local controllers connected to these devices, a central controller and a card issuing device [US Patent No. 5225977, cl. G 06 F 15/30].

The disadvantage of this device is the relatively narrow functionality.

Closest to the technical nature of the proposed is an information processing system containing an information processing device containing identifying information elements, means for identifying information output, comparison means, selective reception means, and also the first and second data processing means with corresponding connections [RU, 2236703, C2, G 06 F 19/00, 09/20/2004].

The disadvantage of this device is the relatively narrow functionality, due to the fact that it allows information processing, but does not allow you to simulate and explore the process of determining the values of the generalized quality indicators of information systems.

The required technical result is to expand the functionality.

The required technical result is achieved by the fact that, in the device containing the data processing unit, a control unit, a memory unit for the quality indicators of information systems, a memory register for the values of the quality indicators of information systems, a group of inputs of which is connected to a group of outputs of the memory unit for the values of quality indicators for information systems, are introduced , a group of blocks of memory of the values of factors, a group of inputs of which is connected to a group of inputs of a block of memory of the values of quality indicators of information systems and upppy of the control unit outputs, a group of factor value memory registers, the group of inputs of which is connected to the group of outputs of the group of factor value memory blocks, and the group of outputs is connected to the first group of inputs of the data processing unit, the second group of inputs of which is connected to the group of outputs of the quality parameter values memory register information systems, as well as the memory block of the parameters of the regression model, the group of inputs of which is connected to the group of outputs of the data processing unit, and the input is connected to the first output of the block systematic way, the second output of which is connected to control inputs of the memory register values of quality indicators and information systems groups of memory registers factor values.

The drawing shows: in Fig.1 is a structural diagram of a device for determining the values of quality indicators of information systems,

figure 2 - control unit.

A device for determining the values of the quality indicators of information systems (Fig. 1) contains a control unit 1, a memory unit 2 of a value of information quality indicators of information systems, a register 3 of a memory of values of information quality indicators of information systems, an input group of which is connected to a group of outputs of a block 2 of a memory of information quality indicator values systems, a group of 4 blocks 4-1 ... 4-m of the memory of the values of factors, the group of inputs of which is connected to the group of inputs of the block 2 of the memory of the values of information quality indicators

systems and with a group of outputs of control unit 1, a group of 5 registers 5-1 ... 5-m of factor value memory, an input group of which is connected to a group of outputs of a group of 4 blocks of factor value memory, and a group of outputs is connected to the first group of inputs of block 6 data processing, the second group of inputs of which is connected to the group of outputs of register 3 of the memory of values of indicators of quality of information systems, as well as block 7 of the memory of parameters of the regression model, the group of inputs of which is connected to the group of outputs of block of 6 data processing, and the input is connected with the first output of the control unit 1, the second output of which is connected to the control inputs of register 3 of the memory of values of quality indicators of information systems and group 5 of the registers of memory of the values of factors.

The control unit 1 (figure 2) contains a clock generator 8 (GTI), the output of which is the second output of the control unit 1, and a pulse counter 9, the group of information outputs of which is a group of outputs of the control unit 1, and the overflow output is connected to the stop input GTI 8 is the first output of control unit 1.

Block 2, group 4 blocks and block 6 can be made in the form of specialized computing devices, and in the particular case in the form of programmable read-only memory devices (ROM), in which each of the given input codes corresponds to the required output codes. The following example of the operation of the device is sufficient for their technical implementation (manufacturing, programming). Register 3 and group 5 registers can be made in the form of multi-bit shift registers, and block 7 in the form of a memory register. GTI 8 and counter 9 pulses are standard elements of computer technology.

The device operates to determine the values of quality indicators of information systems as follows.

Previously, for a specific data processing information system, statistical (experimental) studies are performed. IN

in particular, some generalized indicator Y of the quality of the information system is selected, for example, productivity or processing speed of one document. In addition, factors are set (some particular indicators X = X1 ... Xj ... Xm) that determine the value of the generalized indicator, for example, the frequency of occurrence of errors in the document, the time of detection and correction of errors in the document, etc. The results of experimental studies, in which, in the general case, there is a random component from experiment to experiment, are entered at common current addresses (associated, for example, with the experiment number (i = 1 ... n)), in the corresponding memory blocks: values of the generalized indicator Yi - in block 2 of the memory of the values of the quality index of the information system, and the values of factors Xij - in the corresponding blocks of group 4.

The device starts when starting the GTI 8 and resetting the counter 9, the registers of group 5 and the memory unit 7, for example, through power circuits, which are non-essential features in the framework of this application and are not shown in the drawing.

The counter 9 counts the pulses, which leads to the formation of addresses (experiment numbers) sequentially at its output, which are fed to the address inputs of block 2 and blocks of group 4. In addition, pulses are supplied to the control inputs of register 3 and registers of group 5 simultaneously with the change of addresses GTI 8, which leads to sequential recording of information in the respective registers. The results of the experiments are fed to the data processing unit 6. In this block, the parameters A0, A1, ... Am are calculated for the regression model, which determines the dependence of the generalized quality indicator on particular indicators (factors):

Y = A0 + A1X1 + ... AmXm

In the particular case, these parameters can be calculated using the least squares method. For example, for the case of one factor, these parameters are calculated in accordance with the following dependencies:

A1 = (Sum (Yi) Sum (Yi) -n Sum (XiYi)) / (Sum (Xi) Sum (Xi) -n Sum (Xi Xi))

A0 = (Sum (Yi) -A1 Sum (Xi)) / n,

where the sign Sum (*) means summation over the number of experiments.

Similar formulas can be obtained for a larger value of particular indicators (factors), which is sufficient for programming and manufacturing ROMs, on the basis of which block 6 can be performed.

After the generation of the GTI 8 n pulses, an impulse is generated at the overflow output of the counter 8, according to which the GTI 8 is stopped and the resulting signal generated by block 6 is recorded in block 7 of the parameters memory of the regression model.

Thus, in the proposed device, the required technical result is achieved, associated with the expansion of functionality, since the device allows not only to process information, but also to simulate and study the process of determining the values of generalized quality indicators of information systems using regression analysis methods.
