Description

The invention relates to computer technology, in particular to a system for visual modeling of economic systems.

Under the model of the economic system in the general case is meant a formalized description of the system at a certain level of abstraction. Each model defines a specific aspect of the system, uses a set of diagrams and documents of a given format, and also reflects the point of view and is the object of activity of various people with specific interests, roles or tasks.

Graphic (visual) models are tools for visualizing, describing, designing and documenting the system architecture.

The development of a model of a software system of an economic nature is as necessary as the availability of a project during the construction of a large building. This statement is true both in the case of the development of a new system, and in the adaptation of typical products of class R / 3 or BAAN, which also have their own modeling tools.

Good models are the basis for the interaction of project participants and guarantee the correctness of the system architecture. As the complexity of systems increases, it is important to have good modeling techniques. Although there are many other factors on which the success of the project depends, the presence of a strict standard for the modeling language is very significant.

The composition of the models used in each specific project, and the degree of detail in the general case, depend on the following factors:

- the complexity of the designed system;

- the necessary completeness of its description;

- knowledge and skills of project participants;

- time allotted for design.

Visual modeling had a great impact on the development of hardware in software and CASE-tools in particular. The term CASE (Computer Aided Software Engineering) is currently used in a very broad sense.

The initial meaning of this concept, limited only by the tasks of automation of software development, has now acquired a new meaning, covering most of the processes of the software life cycle.

CASE-technology is a combination of software design methods, as well as a set of tools that allow you to visually simulate a subject area, analyze this model at all stages of software development and maintenance, and develop applications in accordance with the information needs of users.

Most existing CASE tools are based on structural or object-oriented analysis and design methods that use specifications in the form of diagrams or texts to describe external requirements, relationships between system models, system behavior dynamics and software architecture.

The peculiarity of the stated technical problem is that the system of visual modeling of economic systems could provide comparative estimates of the functioning parameters of economic systems in real time.

Known systems that could be used to solve the problem (1, 2).

The first of the known systems contains data reception and storage units connected to control and data processing units, search and selection units connected to data storage and display units, the synchronizing inputs of which are connected to the outputs of the control unit (1).

The construction of this system is based on the traditional functional-modular approach, which provides for a strictly sequential order of operations and is characterized by an avalanche-like increase in complexity, which, undoubtedly, can be a negative factor, since the information flows considered and analyzed have a tendency to translate the flow in one direction only. If the problem is "downstream", then often there is a strong organizational and methodological confrontation with the goal of conducting only limited corrections and providing a solution to the problem without affecting the previous stages of the project.

A significant drawback of this system is the impossibility of solving the problem of online updating of data stored in a data warehouse in real time.

Another technical solution to this problem is known, which contains a model of a telecommunication network of data processing units, the information inputs of which are connected to the data reception and control units, and the outputs are connected to the first group of memory units, the central processor, the inputs of which are connected to the outputs of the memory units of the first group and processing units data, and the outputs are connected to the inputs of the memory blocks of the second group and data display blocks (2).

The basis of this technical solution is an information model containing two main components: diagrams showing the structural characteristics of the model, providing an expressive presentation of information; dictionaries containing the semantic meaning of each element of the model, expressed using short text, and designations (pointers), which together accurately determine the information displayed in the model.

In turn, the information model of the system contains two main components:

- diagrams showing the structural characteristics of the model, providing an expressive presentation of information;

- dictionaries containing the semantic meaning of each element of the model, expressed using short text, and

- designations (pointers), which together accurately determine the information displayed in the model.

The disadvantage of this technical solution is the low speed of the system, due to the large time spent on searching for data corresponding to the semantic value of each element of the model, expressed using short text.

There is also another technical solution to the problem, containing a module for setting parameters for evaluating the operation of the system, a module for measuring and documenting parameters, a module for simulating economic processes, a module for identifying data flows of an economic system, a module for selecting time cycles of data processing, a module for determining the quantitative characteristics of an economic system, a module selection of intervals for receiving input data and a module for generating read and write database signals (3).

The last of the above technical solutions is closest to the described.

The disadvantage of this technical solution lies in its structural complexity and insufficiently high speed, due to the fact that the preparation of the calculated data of economic systems is carried out through the procedure for their search throughout the database volume of the system server, followed by calculation of indicators of economic systems, which with large volumes of data characterizing economic systems, makes it impossible to measure the parameters of the simulated economic system in real time.

The purpose of the invention is to increase the system performance by localizing the addresses of database records by identifiers of parameters of simulated economic processes and forming estimates of the final characteristics of the simulated system in real time.

The system operates as follows.

The information input 15 of the system sequentially receives the current indicators of economic systems, which are, for example, indicators of turnover realized by economic systems, specific income - Yield and income - REV, in the form of codograms of the following contents:

This codogram is adopted by module 1, made in the form of a register into which it is entered by the synchronizing pulse, which is received at the synchronizing input 18 of the system.

From the output 26 of module 1, the indicator type code is sent to the information input 40 of module 2, from the output of 27 module 1, the code of the serial number of the time interval to which the received data belongs is fed to the information input 56 of module 3, the code of the number of indicators from output 28 goes to the information input 68 of module 5, and the codes of the values of the indicators from the output 25 of module 1 are fed to the information input 159 of module 12.

From the input 40 of module 2, the indicator type code is fed to the input of the decoder 30 (Fig. 2), which decrypts the indicator type code and outputs one of its outputs a high potential to the corresponding inputs of elements 33-35 I. For definiteness, we assume that the high potential from the first output of the decoder 30 will be opened element 33 I.

The clock pulse from the input 18 of the system, delayed by the element 37 during the operation of the decoder 30, enters through the open element 33 And to the input of a fixed cell ROM 31, which stores the base address of the database memory area allocated for recording this type of indicator, and reads its contents input register 32.

In addition, the same impulse, having passed the OR element 36, is delayed by the element 38, while reading the base address from the ROM 31, and then arrives at the synchronizing input of the register 32, entering the current address code into it.

From the input 56 of block 3, the code of the specified time interval is fed to the input of the decoder 45 (Fig. 3), which decrypts the code of the time interval and gives one of its outputs a high potential, which arrives at the corresponding inputs of the elements 48-50 I. For definiteness, we assume that the high potential from the third output of the decoder 45 will be opened element 50 I.

The synchronizing pulse from the input 18 of the system, delayed by the element 52 for the duration of the decoder 45, is transmitted through the open element 50 And to the input of the fixed cell ROM 46, which stores the base address of the database memory zone allocated for recording data related to this time period, and reads its contents to the input of the register 47.

In addition, the same pulse, having passed the OR element 51, is delayed by the element 53, while reading the base address from the ROM 46, and then arrives at the clock input of the register 47, entering the base address code into it.

From the output 41 of module 2 and from the output 58 of module 3, the address codes are supplied to the inputs of module 4. The same clock pulse delayed by element 53 of module 3 is delayed by element 54 while the base address code is entered in register 47 and then from module output 59 3 enters the synchronizing input of module 4, providing a summation of the codes of the registers 32 and 47.

The modified address code from the output 42 of module 4 enters through the input 100 of module 7 (Fig. 6) to the inputs of elements 83 And of the group, passes through these elements, open at the second and third inputs with high potentials from the inverse outputs of triggers 81 and 82, and also through elements 86 OR to the information input of the counter 80.

In parallel, the synchronizing pulse from the output of the element 54 of module 3 is delayed by the element 55 for the duration of operation of module 4 and then from the output 60 of module 3 it is, firstly, fed through the input 161 of module 12 (Fig. 10) to the installation input of the trigger 155, confirming its initial state, in which a high potential from the inverse output of the trigger 155 opens the elements 157 And group.

Secondly, the same pulse through the input 103 of the module 7 (Fig.6) and through the element 90 OR enters the synchronizing input of the counter 80 and enters into it a modified address of the record of received indicators.

Thus, at the address output 21 of the system will be formed the address of the record indicator of this type, relating to a specific time period.

In parallel with the process of generating the recording address, the synchronizing pulse from the output of the 90 OR element of module 7 passes through the And element 87, which is open at the second input with a high potential from the inverse output of the trigger 81, is delayed by the element 97 for the time the address code is entered into the counter 80 and then through the OR element 92 Firstly, it is outputted to the system output 23 as a synchronizing recording signal.

This pulse from the output 23 of the system is fed to the input of the first channel of the interruption of the database server. With the arrival of this signal, the database server switches to the subroutine for recording the numerical values of indicators from the output 25 of module 1, which from the input 159 of module 12 (Fig. 10) through elements 157 AND of the group opened by high potential from the inverse output of trigger 155, and elements 158 OR groups are issued to the information output 22 of the system. Data from output 22 is recorded at the address generated at the address output 21 of the system.

The procedure for recording the numerical values of the remaining types of indicators is carried out as described above at their addresses.

In the process of sequential input into the data system of indicators, each of the synchronizing pulses from the output 60 of module 3 is fed to the input 69 of module 5 (Fig. 4), the other input of which is constantly supplied with a code for the number of types of indicators from the output 28 of module 1.

The synchronizing pulses corresponding to the fact of receiving the next type of indicator are fed to the counting input of the counter 65, which counts the number of received pulses.

In each cycle of receiving the next data type of economic systems, the indicators of the counter 65 are compared by a comparator 66 with a given number of data types coming from the output 28 of the module 1 through the input 68 of the module 5, according to a clock pulse from the input 69, delayed by the time the recording address was entered in the counter 80 of the module 7.

After the readings of the counter 65 become equal to the specified number of types of indicators, an output is generated at the output of module 5 5, which fixes the fact that all indicators are ready in the server database and the end of the data input mode.

This pulse is fed to the input 116 of module 8 (Fig. 7) and then fed to the single input of the trigger 111, setting it to a single state, in which the trigger 111 with a high potential from a single output opens the element 112 And the elements 113 And groups, thereby preparing module 8 for receiving data from economic systems, in accordance with which the necessary calculations will be carried out.

The calculation mode of indicators of economic systems begins with the arrival at the information input 16 of the system of the task codogram for calculation in the form of the following structure

The codogram of the task from the input 16 through the elements 113 And the group goes to the information inputs of the register 110 of the module 8 (Fig.7).

The arrival of the codogram is accompanied by a synchronizing pulse fed to the input 20 of the system and then, firstly, to the synchronizing input of the register 110, entering the coding data into the register. Secondly, the same synchronizing pulse passes through the element 114 OR to the output 120 of the module 8 and then goes to the input 123 of the module 10 as a synchronizing signal to start the selection of the data necessary for calculating the data from the server database to the input 139 of block 9 and the input 162 of block 12.

For calculation, it is necessary to introduce a calculation variable, which is set from the workstation of the calculation manager (not shown in the drawing). As a result of this, the code of the selected variable value is issued to the information input 17 of the system, which is entered into the register 110 of the module 8 with the same clock pulse from the input 20.

The code of the time period number from the output 118 of module 8 through the input 138 of module 9 (Fig. 8) is input to the decoder 130, which decodes the digital value of the time period, giving one of its outputs a high potential and thereby opening one of the elements 132-134 AND.

Given the fact that only one of the elements 132-134 AND will be open at one input, then, having passed the corresponding element And, the clock pulse is fed to the read input of a fixed memory cell of the permanent storage device 131, where the base address of the server memory section is stored (in the drawing shown), starting from which in this section of the memory all data of indicators related to this period are stored.

The base address code from the output of the ROM 131 is fed to the information input of the register 129, where it is entered by the synchronizing pulse from the output of the element 136, which delays the synchronizing pulse by the time the codes are read from the ROM. The base address code of the memory section of the database server from the output 140 of block 9 is issued to the input 101 of module 7.

In parallel with this, the synchronizing pulse from the output 141 of the module 9 is fed to the input 104 of the module 7 (Fig.6), from where it is supplied to the single input of the trigger 81 and sets it to a single state, in which the resolution potentials on the two inputs will be for the elements of the 84 AND groups . As a result of this, the code of the base address of a given period from input 101 will be supplied through elements 84 AND groups and elements 86 OR groups to the information input of the counter 80.

In parallel, the clock pulse from the input 104 of module 7 is delayed by the delay element 95 for the duration of the trigger 81 and passes through the OR element 90, firstly, to the clock input of the counter 80, entering the base address code of the specified time period.

Secondly, the same pulse passes through the OR element 91 and the And element 88, open at the second input with a high potential from the direct output of the trigger 81, to the output of the system 24 as a synchronizing data read pulse.

This pulse arrives at the input of the second channel for interrupting the database server, with which the server goes to the subroutine for reading the contents of the database at the address generated at output 21, and transferring them through the information input 17 of the system to the input of the register 110 of module 8 and then from output 119 to the input 122 of the module 10, and then to write them to the buffer memory of block 10, where they are entered by the synchronizing pulses from the server, received at the input 20 of the system.

In addition, the read pulse from the output 24 of the module 7 is supplied to the synchronizing input 76 of the module 6 (Fig.5), from where it is fed to the counting input of the counter 72, counting the number of readout types of indicators.

In each cycle of reading the next type of data of indicators from the server database, the readings of the counter 72 are compared by a comparator 73 with a given number of types of indicators coming from the output 117 of the module 8 through the input 75 of the module 6, according to a synchronizing pulse from the input 76, delayed by the time the counter 72 operates.

If the readings of the counter 72 are less than the specified number of types of indicators, then the output 77 of the module 6 generates a pulse, which through the input 106 of the module 7, firstly, immediately enters the counting input of the counter 80, increasing the read address by one, and secondly , it is delayed by element 96 for the duration of the counter 80 operation and then again passes through OR element 91 and 88 element AND to the system output 24 as another synchronizing data read pulse.

This pulse again arrives at the input of the second channel of the database server interrupt, with which the server goes to the subroutine for reading the contents of the database at the next address generated at output 21, and transmitting the read metric data through the information input 17 of the system to input 122 of module 10.

The process of reading and transmitting the data necessary for the calculation to block 10 continues until the readings of the counter 72 become equal to a given number of types of indicators. In this case, an impulse is formed at the output 78 of module 6, which fixes the fact that all regulatory and reference data is ready for cost calculations by block 10.

This pulse, firstly, through the input 107 of block 7 is supplied to the installation inputs of the triggers 81 and 82, as well as through the element 93 And to the installation input of the counter 80, returning them to their original state.

Secondly, the same pulse is fed to input 121 of module 10 as a control signal for starting the program for calculating control data in module 10.

At the end of the calculations, the results of the calculation are generated at the output of 127 module 10, and at the output of the 125 module 10, a synchronization signal appears, indicating that the cost calculation has been completed.

The code of the results of the calculation from the output 127 of the module 10 through the input 160 of the module 12 passes through elements 156 AND of the group open to this point in time with high potential from the direct output of the trigger 155, and elements 158 OR of the group to the output of the system 22, from where it is issued to the workstation data calculation management (not shown in the drawing).

At the same time, the procedure of documenting the calculation results in the server database is carried out. To this end, the synchronizing signal from the output 126 of the module 10 through the input 152 of the module 11 (Fig.9) is fed to the input of a fixed memory cell ROM 145, which stores the base address of the memory zone of the database allocated for documenting the calculation results, and reads its contents on register input 146.

In parallel with this, the same clock pulse from input 152 is delayed by element 149 while reading the base address from ROM 145 and then goes to the clock input of register 146, entering the base address code from the register output to one input of the adder 148, to the other the input of which reads from the output of the counter 147, which at the given moment is equal to zero.

According to the synchronizing signal from the output of the element 150, which holds the pulse for the time the code is entered into the register 146, the adder 148 summarizes the code of the base address of the documentation of the register 146 and the code at the output of the counter 147, which is zero.

As a result of this, the code of the base address of the documentation will be fixed at the output of the adder, which from the output 154 of the module 11 goes to the input 102 of the module 7, and the synchronizing pulse from the output of the element 150 is again delayed by the element 151 for the duration of the operation of the adder and, firstly, from the output 153 issued to the synchronizing input 105 of module 7, and secondly, it enters the counting input of the counter 147, bringing the first unit into it.

Then the synchronizing pulse from the output 153 of the module 11 through the input 105 of the module 7 (Fig.6) is supplied to the single input of the trigger 82 and sets it to a single state, in which the resolving potential will be the elements And 85 groups.

As a result of this, the base address code from input 102 will be supplied through the AND elements of the group 85 and the OR elements of the group 86 to the information input of the counter 80.

In parallel, the clock pulse from the input 105 of the module 7 is delayed by the delay element 94 for the duration of the trigger 82 and passes through the OR element 90, firstly, to the clock input of the counter 80, entering the base address code into it.

Secondly, the same pulse passes through the 89 And element, open at the second input with high potential from the direct output of the trigger 82, the OR element 92 to the output 23 of the system as a synchronizing recording signal.

This pulse from the output 23 of the system enters the input of the first channel of the interruption of the database server. With the arrival of this signal, the database server switches to the subroutine for recording calculation results from the output 127 of module 10, which from the input 160 of block 12 (Fig. 10) through elements 156 AND groups opened by high potential from the direct output of trigger 155 and elements 158 OR groups issued to the information output 22 of the system. Data from output 25 is recorded at the address generated at the address output 21 of the system.

Thus, the introduction of new modules and new design relationships has significantly improved system performance by eliminating the search for source data for calculating benchmarks across the entire server database.
