The automated management system for servicing GAS Vybory facilities is designed to automate the planning, management and accounting of servicing of geographically distributed system facilities.

Computerized Maintenance Management Systems (CMMS) have been around for over 20 years. Their logical development is modern integrated asset management systems that are designed to reduce equipment maintenance costs and increase productivity (availability ratio).

An automated system for servicing system objects should provide the following functions:

- supply chain management of hardware and software;

- planning and scheduling of work orders, integration with the personnel management system;

- full registration of all costs of service (materials, time, labor) and comparing them with the planned;

- inventory management - replenishment of materials based on the needs of the outfit - orders, supply orders, planned vacations and inventory levels.

- document management - at least the ability to quickly access electronic documents related to hardware and software, outfit - orders and regulations for service maintenance.

The basis of the construction of the service system is information technology, which allows organizing service maintenance of objects based on standard scenarios, according to which service plans for system objects are worked out in advance.

For this purpose, for each case of the possible need for a system object for servicing, a specific service plan is developed taking into account the situation that has arisen.

The plan consists of a number of sections. Each section (subsection) may consist of subsections or points of the plan. The division of the plan into subsections is mainly related to the perception of the plan by the Manager on the screen of collective means.

Each item of the plan contains the name of a specific event, indicating the type (type) of forces, means, resources necessary for its implementation and the identifier of the item of the plan, which must be fulfilled before its implementation.

Implementation methods are developed for each item in the plan, and methodologies (design tasks) are developed for each method, which allow one to determine (estimate) the time of its implementation and the quantitative characteristics of the forces, means, resources involved to fulfill the item in the plan, depending on the specific parameters of the situation at the system object .

In addition, methods are being developed for determining the lead time and values of performance indicators of specific ways to perform service maintenance activities, sections of the plan and the plan as a whole.

The set of all the parameters of the situations at the system’s objects, which is required to calculate the necessary forces, means, resources, time, determine the performance indicators of the service plan and how to carry out specific measures of the plan, is the set of parameters that should go to the service center of the system from the moment of need in service.

Moreover, the structure of the plan should clearly determine the sequence and time standards for the receipt of specific parameters, and many other information indicators used for calculations will make a list of information indicators of conditionally constant information of the service system database.

Thus, the system ensures the completeness of the information necessary for making management decisions.

The software and hardware of the system allows storing, processing, and displaying corresponding plans for collective display facilities. In this case, the plan is displayed with a given degree of detail.

The process of making management decisions by the Management when there is a need for system objects in service using standard plans will look as follows.

When an application for servicing an object of a system is placed under control, its type is determined (the situation is classified). Automatically on the screen in the service center should appear a draft plan created on the basis of a standard one.

At first it will be a plan in which only the column of the event is filled. The structural units of the service center responsible for certain sections of the plan should be notified of the start of work on the section of the plan.

Information from the system object that sent the service request (specific parameters) should also automatically go to the appropriate departments to select a way to implement the service plan and calculate the quantitative and temporal characteristics of the plan items.

The decisive role in the development of the plan belongs to the decision maker. In the process of developing the plan, exercising visual control over the development of the plan, it can, based on the current situation, give instructions on the development of new sections of the plan, on adjustments to the already prepared ones, and choose ways to implement the sections of the plan and the plan as a whole.

The proposed method for making managerial decisions on servicing system objects based on standard plans will reduce the time it takes to make decisions by transferring the main intellectual efforts to develop goal setting and decision design to the stage of everyday activities, when there are no strict time limits, and automation of the process of preparing the draft plan reduce the time for preparing a draft management decision.

Software and hardware should allow for the adjustment of the relevant section of the plan to responsible persons directly from their workplace.

Other users should have access to sections (subsections) of the read-only plan (including users responsible for the section to other sections of the plan).

The system operates as follows.

In the process of developing standard plans for servicing system objects, the input from the workstations of users receives input data in the form of a codogram having the following structure:

the code the code the code Identifier of the type of situation associated with the need for service maintenance of system objects Date of readiness of the plan for servicing system objects The contents of the sections of the service plan of system objects

After the receipt of this codogram to the information input 15 of the system, this codogram is entered into register 1 by a synchronizing pulse supplied to the synchronizing input 18 of the system. From the first output 36 of register 1, the full content of the codogram is issued to the information output 23 of the system.

From the second output 37 of register 1, the crisis identifier code goes to the information input 54 of module 4, from where it is fed to the decoder 42, which decrypts the crisis identifier code and gives one of its outputs a high potential, which goes to the corresponding inputs of elements 44-49 AND .

For definiteness, suppose that the high potential from the first output of the decoder 42 will open elements 44 and 47 And, and in addition, the high potential from the first output of the decoder will be directly issued to the output 57.

The clock pulse from the input 18 of the system, delayed by the element 50 during the operation of the decoder 42, is supplied, firstly, through the element 44 AND to the input of the fixed cell ROM 41, which stores the reference address of the memory zone of the database allocated for recording all plans related to to a given emergency, and reads its contents to the input of the register 43.

Secondly, the same pulse delayed by the element 51 while reading the base address from the ROM 41 is supplied to the clock input of the register 43 and enters the code of the base address, which from the output 55 of the register 43 goes to the input 102 of the adder 8. To another input 101 of the adder 8 from the output 100 of the module 7, a code arrives from the output of the counter 87 through the 90 I elements, open at the second output with high potential from the output 57 of module 4.

The same clock pulse of module 4, delayed by element 52 while the base address code was entered in register 43, firstly, through the output 56 of module 4, it goes to the synchronization input 103 of adder 8, providing the sum of the reference address and counter code 87 of block 7. Given however, that by now the counter 87 was in the initial state and its readings are equal to zero, as a result of the summation, the code of the reference address at the output 104 of the adder 8 will remain unchanged and from the output 104 will go to the input 105 of the adder 9.

Secondly, the synchronizing pulse from the output of element 52 of module 4 is delayed by element 53 for the duration of the adder 9, and then, passing element 47 AND, as well as output 60 of module 4, is fed to input 97 of module 7 and then to the counting input of counter 87 , increasing its readings by one and thereby forming the readings of the counter 87 for the next cycle of work.

In parallel with the process described above, the plan creation date code from the output 38 of register 1 enters the information input 118 of module 10 and then enters the decoder 111, which decrypts the date code and outputs one of its outputs a high potential to the corresponding inputs of elements 113-115 AND.

For definiteness, let us assume that element 113 I will be opened with high potential from the first output of decoder 111.

The synchronizing pulse from the output 56 of module 4 is supplied, firstly, to the input 119 of the module 10 and then through the element 113 And fed to the input of a fixed cell ROM 110, which stores the address of the memory zone of the database allocated for recording all plans in a specified period of time , and reads its contents to the input of register 112.

Secondly, the synchronizing pulse from the input 119 of the module 10 is delayed by the element 116 for the time of reading the code of the time period and enters the synchronizing input of the register 112 and enters the code of the time period, which from the output 120 of the register 112 goes to another information input 106 of the adder 9. Recall that the first input 105 of the adder 9 from the output 104 of the adder 8 receives the code of the reference address of a given crisis situation.

The synchronizing pulse from the output of element 116, delayed by element 117 for the time the code of the time period is entered in register 112, from the output 121 of module 10 is supplied to the synchronizing input 107 of the adder 9, fixing the total address of the record, which from the output 108 of the adder 9 goes to the input 152 of the module 12 In addition, the clock pulse from the output 121 of the module 10 is supplied to the clock input 154 of the module 12.

From the input 152 of the module 12, the generated write address is supplied to one of the inputs of the And 144 elements of the first group, which will be opened by high potential from the inverse output of the trigger 141. The state of the trigger 141 is determined by the synchronizing write pulses supplied to the input 154 of the block 12, and the synchronizing read pulses received input 155 of module 12.

Considering that at the given time, the input 154 of the module 12 received a synchronizing write pulse, then passing to the installation input of the trigger 141, this pulse will confirm it to its original state, in which high potential from the inverse output of the trigger 141 will be opened as elements 144 And groups, so is element 142 I.

The code of the recording address from the output of the 144 AND group elements passes through the OR elements 146 of the group to the information input of the counter 140, to the synchronizing input of which there is a pulse from the input 154 of the module 12, which passed through the chain: the OR element 147 and the delay element 149, delaying the pulse for the duration of the operation adder 9.

In addition, the same pulse from the output of the delay element 149 passes through the And element 142, is delayed by the element 150 for the time the address code is entered into the counter 140, and then from the output 159 through the system output 31 it enters the input of the first channel of the database server interrupt.

With the arrival of this signal, the database server switches to the routine for recording the readings of register 1 from the output 23 of the system at the address generated at the output 24 of the system.

The procedure for recording subsequent sample plans for other service situations is similar.

To obtain relevant information from the server database, each user who has access to the appropriate sections of the database of standard plans, at his automated workstation generates a query codogram and presses the "View" button.

The structure of the codogram formed at the user's workstations has the following structure:

the code the code Identifier of the type of situation associated with the need for service maintenance of system objects User Workstation Identifier

In this case, the codes of the identifier of the type of situation and the identifier of the user's workstation through input 16 go to register 2, where they are entered by a synchronizing pulse from input 19.

From the first output 39 of register 2, the crisis identifier code is supplied through the input 72 of module 5 to the input of the decoder 65.

The decoder 65 decodes the identifier code of the type of situation, giving out one of its outputs high potential. For definiteness, we assume that a high potential is received at one input of element 67 I.

In parallel with this, the synchronizing pulse from input 19 is delayed by element 70 for the time the code is entered in register 2 and the decoder 65 is triggered, and then it polls the states of elements 66-68 I.

Given the fact that only one element And will be open at one input, then passing through this element And, the clock pulse arrives, firstly, at the read input of a fixed memory cell of read-only memory 64.

In a fixed memory cell, the code of the reference address of the first memory cell of this type of situation is stored in the server database and the code of the number of plans in the server database, according to which it is supposed to act in the conditions of a specific service situation of the system object.

The structure of the codogram in the memory cell has the following structure:

the code the code Code of the reference address of the first memory cell of the specified type of situation in the server database Code for the number of action plans for a given type of situation in the server database

The code of the reference address of the first memory cell and the code of the number of plans are read from a fixed memory cell and are sent to the outputs 74, 75 of module 5, respectively.

In parallel with this, the read pulse of the fixed memory cell of module 5, passing through the element 69 OR, immediately from the output 73 of module 5 enters through the input 155 of module 12 to the single input of the trigger 141 and sets it to a single state, in which it opens one input of elements 145 And groups, as well as element 143 And, while at the same time closing low-potential elements 144 And groups together with element 142 I from their inverse output.

The code of the reference address of the first memory cell from the output 74 of the module 5 through the input 153 of the module 12 and the AND elements 145, as well as the OR elements 146 of the group, is fed to the information input of the reverse counter 140.

The same clock pulse from the input 155 of the module 12 passes through the OR element 147, is delayed by the delay element 149 for the time of reading the code from the memory block 64 and the trigger 141, and arrives at the clock input of the reverse counter 140, fixing the code of the reference address of the first memory cell in the counter this crisis in the server database.

In addition, the same pulse from the output of the delay element 149 passes through the AND element 143, the OR element 148 and is delayed by the delay element 151 for the time that the reference address code was entered into the counter 140, and through the output 160 of the module 12 and the output 32 of the system it enters the input of the second interrupt channel server.

According to this signal, the server goes to the subprogram for interrogating the contents of the memory cell at the address generated on the address output of the system 24 and issuing the read data through the input 17 of the system to the information input of register 3, where they are entered by the synchronizing pulse of the server entering the input 20 of the system.

Simultaneously with this process, the code for the number of records of plans for this situation from the output 75 of module 5 enters through the input 132 of module 11 to the information input of the register 122, where it is also entered by the pulse from the output 73 of module 5 through the input 133 of module 11.

In parallel with this, the user workstation identifier code from the output 40 of the register 2 enters through the input 84 of the module 6 to the input of the decoder 77.

The decoder 77 decodes the user ID code of the user workstation, giving out one of its outputs high potential. For definiteness, we assume that a high potential is received at one input of element 78 I.

In parallel with this, the synchronizing pulse from the input 20 is delayed by the element 82 for the duration of the operation of the decoder 77, and further, it polls the states of the elements 78-80 I.

Considering the fact that only the And element 78 will be open at one input, then passing through this And element, the clock pulse arrives, firstly, at the read input of a fixed memory cell of the permanent storage device 76, where the address code of the user workstation is stored, and reads it through the output 85 of module 6 to the information input 167 of module 13.

Secondly, the same read pulse, having passed the OR element 81, is delayed by the delay element 83 for the reading time of the contents of the fixed ROM cell.

Further, from the output 86 of module 6, this pulse enters through the input 169 of module 13 to the synchronizing input of register 161, fixing the address code of the user's workstation in the register.

The decoder 162 decrypts the address code of the user's workstation and with high potential at one of its outputs opens the And elements of one of the groups 163-165.

At the same time, the pulse from the input 169 of the module 13, the delayed delay element 166 for the duration of the decoder 162, the code of the first read from the output of the register 3, passing through the input 168 of the module 13 and the corresponding group of elements And 163-165, through the corresponding output 170- 173 of the module 13 and, accordingly, the outputs 35-37 of the system are issued to the user's workstation.

The user is given the opportunity to view all plans for this service situation in the server database and get the information he needs.

To do this, the user uses the "Forward" and "Back" keys, the signals from which are fed to the control inputs 21, 22 of the system, respectively.

When you press the "Forward" key, the pulse from the input 21 of the system passes through the input 134 of the module 11 to the counting input of the counter 123, fixing the number of scanned plans.

This number of plans is compared by the comparator 124 with the number of plans related to this service situation recorded in the register 122, according to the signal from the output of the delay element 129, delaying the pulse from the input 134 for the time of operation of the counter 123.

If the number of plans viewed is less than the specified number of plans in the register 122, then an output 175 is generated from the comparator 124, which passes through the element 127 OR to the output 136 of the module 11 and gave it through the input 156 of the module 12 to the summing input of the reversible counter 140, forming the next read address output 24.

In addition, the same pulse, passing through the OR element 148 and the delay element 151, delaying this pulse for the duration of the operation of the reverse counter, passes to the output 160 of the module 12 and then to the output 32 and again goes to the input of the second channel of the server interrupt.

By this signal, the server again switches to the subprogram for interrogating the contents of the memory cell at the address generated at the address output of the system 24 and issuing the read data through the input 17 of the system to the information input of register 3, where they are entered by the synchronizing pulse of the server entering the input 20 of the system.

The described process of reading plans from the server database and issuing them to the user's workstation continues until the number of entries in the register 122 of module 11 is equal to the number of plans read from the database recorded by counter 123. The indicated moment will be recorded by issuing an impulse the output of 176 comparator 124.

The pulse from the output 176 of the comparator 124, firstly, through the element 128 OR enters the output 137 of the module 11 and then to the input 157 of the counter 140, reducing its readings by one. In addition, the same pulse, passing through the OR element 148 and the delay element 151, which holds this pulse for the duration of the operation of the reverse counter, passes to the output 160 and the output 32 of the system and then again goes to the input of the second channel of the server interrupt.

By this signal, the server again switches to the subprogram for interrogating the contents of the memory cell at the address generated at the address output of the system 24 and issuing the read data through the input 17 of the system to the information input of register 3, where they are entered by the synchronizing pulse of the server entering the input 20 of the system.

Secondly, the same pulse from the output 176 of the comparator 124 is delayed by the delay element 130 for the duration of the pulse and through the OR element 126 is fed to the subtracting input of the counter 111, reducing its readings.

After that, the user can go back to the standard plans by pressing the "Back" button. The pulse from the input 29 through the OR element 116, firstly, is fed to the subtracting input of the counter 123, and, secondly, after the passage of the OR element 138 and delayed by the element 131 for the duration of the counter 123 operation, it goes to the synchronizing input of the comparator 125.

At this signal, the comparator 125 compares the readings of the counter 123 with "zero". If the counter 123 is greater than zero, then a signal is generated at the output 177 of the comparator 125, which, through the OR element 128, is output to the output 137 of the module 11 and then to the subtracting input of the reverse counter 140.

If the readings of the counter 123 are equal to zero, then a pulse is generated at the output 178 of the comparator 125, which, through the OR element 127, is similar to the output 136 of the module 11. Then the same pulse through the input 156 of the module 12 is fed to the summing input of the reverse counter 140, transferring the user to direct viewing mode of typical plans in the server database.

In other words, the user is given the opportunity to repeatedly review all the typical service plans for system objects and reasonably select the data of interest to him.

Thus, the introduction of new modules made it possible to significantly increase the system performance by excluding the search for the optimal service plan for the entire server database and localizing the search only by the time and distinctive signs of a particular application of the system for service.
