Description

The invention relates to computer technology and can be used to assess the preferred level of unification of technical systems (TS) in order to minimize the cost of designing and manufacturing vehicles with a sufficient level of their effectiveness.

Applicants are not aware that such a technical problem would be solved. This is because when assessing the preferred level of vehicle unification, there is no simultaneous accounting for the amount of financing for their design and manufacture and the level of their effectiveness.

The technical result of the claimed solution is to optimize the level of vehicle unification, taking into account their effectiveness and the amount of funding for their design and manufacture.

If the level of unification is too high, the amount of financing is reduced due to the use of elements and subsystems that were already in operation. However, in this case, an excessively low level of vehicle efficiency is possible due to the low level of manufacturability of old elements. Too low a level of unification provides an acceptable level of TS efficiency, but a high level of manufacturability of new elements and subsystems requires large amounts of financing that can exceed the general cost estimate.

The assessment of the preferred level of vehicle unification can be carried out using the generalized criterion P _i , the value of which for the i-th level of vehicle unification is determined by the formula

Where:

m - the number of analyzed levels of vehicle unification;

W _i - vehicle efficiency at the i-th level of its unification (for example, the probability of a task);

S _i - the amount of funding for the design and manufacture of vehicles at the i-th level of unification, thousand rubles

The value of S _i can be calculated as follows:

Where:

K _npi - applicability coefficient characterizing the i-th level of vehicle unification;

S _ui - the cost of the component parts of the vehicle used in

i-th level of its unification, thousand rubles;

S _нi - the cost of new component parts of vehicle components at the i-th level of its unification, thousand rubles;

G - coefficient taking into account the degree of development of the elements of the vehicle that were in use (it depends on the number of years of use).

The coefficient of applicability, characterizing the level of unification of the TS, is the ratio of the number of previously used elements to the total number of elements contained in the TS.

Experience shows that the coefficient G can be estimated by the following formula:

T _max - the maximum possible time of use (development) of the unified elements (subsystems) of the TS, year;

T is the actual time of use (development) of these elements, year.

Taking into account that for modern TS T _max = 10 years, expression (3) can be written as:

Since it is advisable to increase the mentioned efficiency, and to reduce the amount of financing, it is necessary to search for the value of K _npi that provides the greatest value of the criterion P _i , i.e. P _imax . This position is clearly illustrated using table 1 (in this example, the following values are accepted: T = 4 years, G = 0.25).

Table 1 Numerical values of parameters for assessing the preferred level of technical system unification Unification Level Option Number one 2 3 four 5 6 7 8 9 K _npi 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 S _ui , thousand rubles 10 twenty thirty 40 fifty 56 60 63 65 S _ni , thousand rubles 40,0 35.0 32,0 30,0 28.0 26.5 25.5 25.0 24.8 S _i , thousand rubles 36.25 29.00 24.65 22.00 20.25 19.00 18.15 17.60 17.11 W _i 0.98 0.96 0.92 0.88 0.85 0.83 0.79 0.74 0.65 P _i 0,027 0,033 0,037 0,040 0,042 0,044 0,043 0,042 0,038 P _imax 0,044

The table shows that the increase in the criterion P _i initially provided a significant reduction in funding. However, an increase in K _npi , i.e. the share of already used elements (subsystems) of the vehicle, causes a significant decrease in efficiency, which leads to a decrease in the criterion P _i at values of K _npi > 0.6. In this situation, the sixth option is its preferred level of unification: K _npi = 0.6.

The technical result is achieved in that the device for assessing the preferred level of vehicle unification contains from the first to fourth groups of input registers, the input register, the first, second and third groups of multiplication blocks, a division block, a group of adders, a group of subtraction blocks, a group of delay elements (EI) , a group of division blocks, a group of output registers, a group of indication blocks, a clock generator and a pulse distributor (RI), the clock input of which is connected to the output of the clock generator, the first output of the RI - with write inputs from the first to fourth groups of input registers and input register, the second output - with read input of the input register, third, fourth, fifth and sixth outputs - with read inputs of the first, second, third and fourth groups of input registers, seventh and the eighth outputs are, respectively, with the recording inputs and reading inputs of the group of output registers, the information inputs of the first input group, consisting of m elements, are the input of the initial information, and to the information inputs from the first to m-th input registers of the first group receive values of K _npi , 5 characterizing the coefficient of applicability, determining the i-th level of unification of the technical system (TS), the information inputs of the second group of input registers, consisting of m elements, are the input of the initial information, and information inputs of the first through m-th input registers of the second group received values S _ui, characterizing value components (elements) CU former use, when i-th level of its alignment, the third group of information inputs Rin dnyh register consisting of m elements are input reference source information, wherein the information input of the first through m-th input registers of the third group received values S _HI characterizing the cost of new components (elements) CU at i-th level of its alignment, data inputs of the fourth group input register consisting of m elements are input reference source information, wherein the received value W _t to data inputs of the first through m-th input registers fourth group characterizing effective TS at the i-th level of its unification, the information input of the input register is the input of the initial information, and its information input receives the value T, which characterizes the actual time of use (development) of the unified elements TC, the outputs of each element of the first and second groups of input registers are connected respectively, to the first and second inputs of the corresponding elements of the first group of multiplication blocks, consisting of m elements, the outputs of each of which are connected to the first inputs of the corresponding elements the second group of multiplication units, consisting of m elements, the second inputs of each of which are connected to the input of the division unit, the input of the divider of which is connected to the output of the input register, the outputs of each element of the second group of multiplication units are connected to the first inputs of the corresponding elements of the adder group, consisting of m elements, the second inputs of each of which are connected to the outputs of the corresponding elements of the EZ group, consisting of m elements, the inputs of each of which are connected to the outputs of the corresponding elements of the third group py of multiplication blocks, consisting of m elements, the first inputs of each of which are connected to the corresponding elements of the third group of input registers, and the second inputs - to the outputs of the corresponding elements of the group of subtraction blocks, consisting of m elements, the inputs of which are subtracted from each of the elements are connected to the outputs of the corresponding elements of the first group of input registers, the outputs of each element of the fourth group of input registers are connected to the outputs of the dividend of the corresponding elements of the group of division blocks, consisting of m e ementov inputs divider of each of which are connected to the outputs of the respective elements adders group and outputs - to the data inputs of the respective elements of the output register comprising m elements, the outputs of each of which are connected to the inputs of the corresponding elements of the display units consisting of m elements.

Figure 1 presents the functional diagram of a device for assessing the preferred level of vehicle unification (to eliminate the cumbersome connection between the RI and the control inputs of the respective blocks are not shown completely, but are indicated by the numbering of inputs and outputs).

Figure 2 shows the sequence diagram of the operation of the claimed device (the ordinates indicate the numbers of the outputs of the RI, and the abscissa axis indicates the number of ticks), and the duration of the various computational operations (addition and subtraction is one clock, multiplication is eight clocks, division is sixteen clocks) presented at the top of FIG. 2.

A device for assessing the preferred level of vehicle unification (Fig. 1) contains the first 1, second 2, third 3 and fourth 4 groups of input registers, consisting of m elements, input register 5, first 6, second 7 and third 8 groups of multiplication blocks, consisting of m elements, division block 9, group of 10 adders, consisting of m elements, group of 11 subtraction blocks, consisting of m elements, group of 12 EZ, consisting of m elements, group of 13 division blocks, consisting of m elements, group of 14 output registers consisting of m elements, a group of 15 display units, with toyaschuyu of m elements clock generator 16 and the RI 17.

It should be noted that the division unit 9 has only one input: the input of the divider. This is because the value of the dividend, equal to one, is constantly "wired" in this block. In addition, each element of the group of 11 subtraction blocks has only one input: the input is subtracted. This is due to the fact that the value to be reduced, equal to one, is constantly "wired" in each element of this group.

A device for assessing the preferred level of vehicle unification works as follows. The information inputs of each of the elements of the first group 1 of the input registers are sent the values of the coefficients of applicability, characterizing the i-th level of unification of the vehicle, K _npi . The information inputs of each of the elements of the second group of 2 input registers are fed with the value S _{ui of the} TS components (elements) that were in use at the i-th level of its unification. The information inputs of the third group of 3 input registers are sent the cost values S _{ni of the} new components (elements) of the TS at the i-th level of its unification. The information inputs of the fourth group of 4 input registers receive the values of the effectiveness of W _i TS at the i-th level of its unification. The value of the actual time of use (elaboration) of the unified elements of the TS is sent to the information input of the input register 5. Moreover, the control signal to the recording inputs of groups 1, 2, 3 and 4 and block 5 is supplied from the first output of RI 17, the pace of which is set by the generator 16 clock pulses.

According to the signal from the second output of RI 17 to the read input of the input register 5, the value of T goes to the input of the divisible division unit 9, from the output of which the coefficient G, determined by formula (4), is sent to the second inputs of each element of the second group 7 of multiplication units. According to the signals from the third and fourth outputs of RI 17 to the read inputs of each element of the first 1 and second 2 groups of input registers, respectively, the values of K _npi and S _ui from the outputs of these groups are sent respectively to the first and second inputs of each corresponding element of the first group of 6 multiplication blocks. From the outputs of this group, the values of S _ui · K _npi · are supplied to the first input of each corresponding element of the second group of 7 multiplication blocks, from the outputs of which the values of S _ui · K _npi · G are sent to the first inputs of each corresponding element of the group of 10 adders. According to the signal from the fifth output of RI 17 to the read inputs of each element of the third group of 3 input registers, the values of S _ni from the outputs of this group are sent to the first inputs of each corresponding element of the third group of 8 multiplication blocks. The values of K _npi also go to the input of the deductible of each corresponding element of the group of 11 subtraction blocks, from the output of which the values (1-K _npi ) are supplied to the second input of each corresponding element of the third group of 8 blocks of multiplication. From the outputs of this group, the values of S _ni · (1-K _npi ) are sent through group 12 of EZs (to ensure the simultaneous arrival of signals) to the second input of each corresponding element of group 10 of adders, from the outputs of which the values of S _i calculated by formula (2), are sent to the input of the divider of each corresponding element of the group 13 of division blocks.

According to the signal from the sixth output of RI 17 to the read input of each element of the fourth group of 4 input registers, the efficiency values W _t TS at the i-th level of its unification are directed to the input of the dividend of each corresponding element of the group 13 of division blocks, from the outputs of which the values of the generalized criterion P _i , determined by the formula (1), are fed to the information input of each corresponding element of the group of 14 output registers. In this case, the control signal to the recording inputs of this group is sent from the seventh output of RI 17.

To clearly display the result of the operation of the device by a signal from the eighth output of the RI to the read input of each element of the group of 14 output registers, the values of P _{i are} sent to the input of each corresponding element of the group 15 of display units.

Visual analysis of the information displayed on the elements of this group allows you to select the highest value of the criterion P _i , i.e. P _imax . This value will correspond to the value of K _np characterizing the preferred level of vehicle unification. For example, if P _imax is on the sixth element of the group of 15 display units, then the sixth value of the coefficient of applicability will be the preferred level of unification, i.e. the desired value of K _np = 0.6.

Thus, the technical result of the claimed invention is achieved not due to the mathematical apparatus, but due to the technical means (blocks and elements) mentioned in the description of the operation of the device. The described device allows you to evaluate the preferred level of vehicle unification in order to minimize the cost of designing and manufacturing vehicles with a sufficient level of their effectiveness.

Industrial applicability is justified by the fact that it can be used in different areas (industries) of production when choosing the preferred level of vehicle unification.

It should be expected that this invention can be of great importance in the field of mass production, for example, in mechanical engineering (automobiles, machine tools, etc.), electronic and radio industries.
