FIG. 1 shows a diagram of the formation of the product life cycle.

The implementation of the invention.

The invention is implemented on a production line in which, in one embodiment, a final product is made from raw materials. Raw materials go through several stages of production; at each stage their own tools (equipment) are used; stages can be carried out automatically, automatically, manually; Each stage of production is regulated by the operations performed on it. In solutions known from the prior art, control is carried out only at the final stage and at a small number of key stages, usually this control is exclusively quality control. In the invention, the developers propose to further control the time at all stages of production. The proposed solution is not limited in the amount of information stored; at each stage, information about the parameters of production and products can be stored: overall dimensions of products, temperature, environmental humidity, etc.

To carry out such control, each product from the very beginning of the production cycle is provided with a label, which is used to identify the product and simplify time control.

In a simplified form, the implementation of the control method is as follows:

1. At the beginning of the production process, a label is placed on each product (if necessary, a product element).

2. At the first stage, over each product (or item of the product), all the operations prescribed by the technical regulations are performed at this stage, the time of at least part of the operations is monitored by scanning the tags with an appropriate control tool, for example, a QR tag scanner or an RFID tag scanner and marking completion of the operation, record the equipment used, and then enter this information into the database.

3. If necessary, control the quality of the operation performed for products (product items), using a scanner to identify the product (product item) and then entering information about quality control into the database.

4. Repeat steps 2, 3 for each stage of production of the product (product item).

5. Determine the production time of one product and a batch of products, taking into account the time for maintenance of equipment used in the production.

6. Send the finished marked product (product item) to the storage location.

To implement the invention, a computer system is used that contains the label scanners, the labels themselves, a computer with a database, a communication network between the computer and the scanners. A computer system can be implemented on the basis of mobile devices, including mobile communication devices. A computer within the framework of this solution is understood as a tool that implements the functionality of such a computing tool as a computer, this tool can take the form of a laptop, terminal, smartphone, etc.

Tags can be RFID tags, QR codes, or any other suitable type.

Scanners are selected based on the type of tag so as to be able to read tag information. Preferably, the scanner is a mobile device, alternatively a mobile phone.

A communication network can be implemented on any communication protocol, at least one or more of: Bluetooth, Wi-Fi, infrared, cellular, etc.

A computer with a database stores information about all routine work that must be carried out on the product, and also stores all relevant information about all manufactured and manufactured products, at least information about the time of operations on the product, information about quality control, information about the equipment used .

The product may consist of one element, which undergoes a series of technological operations to obtain finished products from raw materials, and may also consist of many elements, each of which undergoes its own technological operations, and the finished product is then assembled from elements if necessary.

DETAILED DESCRIPTION OF EMBODIMENTS.

The beginning of production is the receipt of an application for the manufacture of products. The application contains at least the name of the product and the number of copies of the products. If there is no production technology in the automated control system, then a corresponding request is sent to the technologist to form technological maps for this product.

After the formation of technological maps, it is possible to make a forecast for the production time of products, based on at least several factors from: the timing of the re-adjustment of production, the availability of necessary materials in the warehouse, the timing of the supply of materials, production time from the information of the technological maps, the availability of free time for staff and equipment the simultaneous production of other products, the timing of repair and maintenance of equipment.

As a rule, when the product is first launched, all the parameters used to predict the production time are approximate and inaccurate. The claimed solution proposes a method and system for more accurately calculating the timing of production of a batch of products.

Since according to the proposed solution each stage of production of each product is controlled, it is easy to determine the total production time of one product t: as the sum of the durations of all stages.

There is a restriction on the number of products manufactured in parallel n, due to the limited production capacity of the enterprise. Limitations are associated with the availability and performance of equipment and tools, the availability and qualifications of the necessary personnel. The necessary equipment, tools, personnel and its qualifications are determined according to the technological maps.

Thus, the total time T of manufacturing a batch of N products is determined by the expression:

T = t⋅N / n

For a more accurate determination of the production time of a batch of products, it is necessary to take into account the schedule of maintenance and repair (MRO) of equipment.

Since the claimed decision fixes the execution time of each stage of the production of the product, then using the information of technological maps that indicate the equipment used at each stage, you can determine the time of use of each piece of equipment.

As a rule, MRO is carried out in accordance with the operating time of a particular equipment. In the stated decision, based on the number of products to be produced and the time it took for each piece of equipment to be used in the production of one product, the future operating time of each piece of equipment is determined. Based on this time, the declared decision plans to perform MRO during the production of a batch of products, the time for MRO is taken into account when calculating the production time of a batch of products.

A more accurate way to determine MRO time is to evaluate not only the total operating time of a piece of equipment, but also the estimated idle time and working time under load of this piece of equipment. These data can be obtained from routings and from product information that is stored in the previously mentioned database.

In one of the options for idling time and operating time under load, reducing and increasing coefficients are introduced, which leads to a more accurate assessment of wear and, accordingly, to a more accurate choice of MRO time. For example, by means of the coefficients, it is specified that the time under load is 2 times more likely to affect equipment wear than the idle time.

In one embodiment, the equipment is divided into three groups according to the criticality of MRO. Group A - equipment with critical MRO time (high critical equipment), group B - equipment with standard MRO time (medium critical equipment), group C - equipment with flexible MRO time (low critical equipment).

In group A, maintenance and repair time transfers are not permissible, since this can lead to significant consequences that are difficult to eliminate: equipment failure, production of defective products, and increased danger to the operator. In group B, maintenance and repair transfers are undesirable, but acceptable within certain predetermined limits, in group C, maintenance and repair transfers do not greatly affect the operation of the equipment and the quality of manufactured products.

In the stated decision, each piece of equipment is assigned to its own group: A, B, C, and the maintenance and repair schedule is built on the basis of this assignment. Group A equipment undergoes MRO according to its regulation without deviations. Group B equipment undergoes maintenance and repair taking into account the need to complete the stages of production of products, for example, a limit is set on how much maintenance and repair of equipment can be delayed, as an option, by 20% of the time required for maintenance and repair. Group C equipment undergoes MRO at the moments when this equipment has a sufficient interruption in operation.

In one embodiment of the invention, based on the stored MRO results, the MRO terms change. So, if routine maintenance and repair work showed the absence of measurable equipment degradation, then the maintenance and repair work period increases, if the degradation was more than expected, then the maintenance and repair work time decreases.

It is also possible to change the criticality group of maintenance and repair of equipment. If routine maintenance and repair or quality checks of products manufactured using this equipment showed significant degradation if the maintenance and repair periods are exceeded, the criticality group changes from C to B or from B to A.

This decision does not examine in detail the case of a shortage of raw materials for the production of the required number of products, however, an estimate of the total amount of raw materials can obviously be realized by monitoring each stage of production.

Technological maps of production contain data on the qualifications and training of performers for each stage of production. Different stages require different qualifications of the staff, and this is taken into account in the framework of the announced decision.

The number and training of personnel obviously affects the number of manufactured products along with equipment.

In the stated decision, the database stores information on the stages of production of the product and the required qualifications of the contractor (obtained from the technological map), as well as a list of contractors indicating their qualifications (s).

In the stated decision, the distribution of performers provides a list of performers approved for each stage of production. The criterion for admission is at least one of: qualifications, training, level of admission, working hours. The specified functionality is implemented using a computing tool (PC, tablet, mobile phone, terminal, etc.) associated with a database containing data on the requirements for performers (available from technological maps) and data on the qualifications of all performers available at the factory .

Moreover, for the purposes of the optimal distribution of performers by stages of production, performers with the narrowest qualifications have the highest priority in distribution, and performers with the broadest qualifications (having access to any stage of production) have the lowest priority. When distributing performers by stages, the aforementioned computing tool provides a list of performers sorted by priority, which allows simplifying and speeding up the distribution so as to ensure the most efficient production of products.

When carrying out production before the start of the shift, the site master is provided with a list of products that need to be made in the shift. According to these products, according to the technological maps, using the computing tool displays the following information:

Необходимое количество сырья на смену;

Further optionally follows the stage of quality control of the manufactured product, which is also fixed in a mobile device with the appropriate software. If all the monitored parameters (indicated in the technological maps) are in the required reference ranges, then the product is recognized as passed control, otherwise it is rejected and sent for revision, processing or disposal.

A product that has passed control at one of the stages is sent to the next production stage, where subsequent production operations and further quality control are carried out.

After the last stage is completed, the product is considered finished, and it is shipped to the place of storage of the finished product.

Further, knowing the operating time of the equipment involved (from the data of technological maps), a maintenance and repair plan is formed and, based on it, the production time is specified.

If there is data on the amount of materials needed for the manufacture of products, then amendments are made if there is a shortage of the required amount of materials at the storage sites.

Similarly, if the lack of personnel is the limiting factor in production capacity, an adjustment is made for the training time for existing or additional personnel.

The master of the production site generates a shift task for all performers involved in the production of these products. At the beginning of production, each product is marked with a label, at each stage the label reads all the relevant information about the product and its production process is stored in a database. At the end of production, a product passport is formed, which records information about the materials from which the product is made, the stages of production that it went through, the performers who participated, the equipment and any other relevant information that is then easily obtained, knowing the unique label of the product.

The finished product is shipped to the customer, goes into operation, in case of warranty or non-warranty repair, failure, breakdown or correct work on the product label, you can restore the history of its production and identify at what stage and as a result of which the problem arose.

DESCRIPTION OF EMBODIMENTS.

Consider an embodiment of the invention on a simplified example of the production of a collapsible dumbbell. The collapsible dumbbell consists of a handle, removable weighting materials and clamps.

It is known from the technological documentation that the production of a handle consists of a step 11 of turning a round blank to the desired diameter and cutting the turned blank to the desired length, step 12 of drilling two holes along the axis of the handle, step 13 of threading in the holes, step 14 of applying a rubber coating.

From the technological documentation it is known that the production of a removable weighting agent consists of a step 21 of turning a round blank to the desired diameter and cutting the turned blank to the desired length, step 22 of drilling a through hole along the axis of the weighting compound, step 23 of painting.

From the technological documentation it is known that the production of a clamp consists of a step 31 of turning a round blank to the desired diameter and cutting of a turned blank to the desired length, step 32 of threading on the clamp, step 33 of forming the head of the clamp.

From the technological documentation known, the duration of each stage and the equipment used at each stage. For example, the durations of steps 11, 21, 31 are 4, 2, 3 minutes, respectively, while they are carried out on a TS1 lathe; the durations of steps 12, 22 are 2, 1 minute, respectively, while they are carried out on a CT1 drilling machine; the durations of steps 13, 32 are 5 and 4 minutes, respectively, while they are carried out on a TS2 lathe. The durations of steps 14, 23, 33 are 11, 20, 3 minutes, respectively.

In the simplest case, all stages of the production of a collapsible dumbbell are carried out sequentially. At the first stage, a mark is set on each blank, then at each stage the performer fixes the beginning and end of the stage by scanning the mark. Thus, statistics are collected in the database on the implementation time of each stage, as well as the time the part moves between stages. Since each stage is associated with the use of its equipment, information on the total use of each piece of equipment in operating mode, as well as in idle mode, can be extracted from the database if the equipment does not turn off after each stage is completed.

Having data on the time of use of equipment in the production of one part of the dumbbell and knowing the terms of maintenance known from the documentation for the equipment, you can predict the time of the maintenance of each piece of equipment, and then adjust the production time of a batch of dumbbells.

In this case, one collapsible dumbbell consists of one handle, 6 weighting materials and two clamps. To produce one dumbbell, you need time: 22 (4 + 2 + 5 + 11) minutes per handle, 138 (6 * 23 (2 + 1 + 20)) minutes for 6 weighting agents, 20 (2 * 10 (3 + 4 + 3) )) minutes on two clamps. In total, one dumbbell in the sequential manufacture of each part requires 180 minutes.

For example, according to the documentation, the TS1 machine is serviced after 100 hours of operation and takes 2 hours, the TS2 machine is carried out after 50 hours of operation and takes 1 hour, the ST1 machine is after 30 hours of operation and takes 3 hours. During the collection of information about each stage of production, it was found that when manufacturing one dumbbell, TC1 works for 22 minutes +8 minutes in idle mode, TC2 works for 11 minutes +6 minutes in idle mode, CT1 works for 8 minutes +0 minutes in idle mode move.

In one embodiment, a reduction factor of 0.5 is applied to the idle mode, which leads to a weighted TC1 operating time of 26 (22 + 4) minutes, TC2 of 14 (11 + 3) minutes, CT1 of 8 minutes.

Thus, TC1 should be stopped for service after the production of 231 dumbbells, TC2 - after the production of 214 dumbbells, CT1 - after the production of 225 dumbbells.

The total production time of a batch of 300 dumbbells will consist of production time and service time and will be 906 (300 * 3 + 2 + 1 + 3) hours.

Monitoring the production time of each element of the dumbbell allows you to accurately track the time when maintenance is necessary for each specific equipment used.

On the other hand, control of the production time of each element of the dumbbell allows you to specify on the fly the production time of each element, which may differ from that planned in the technological documentation.

Since part of the stages for the production of a dumbbell can be carried out simultaneously with several elements, you can enter the reduced time of the stage (the ratio of the time of the stage to the number of elements). So if 20 weighting agents are subjected to painting at the same time, then the reduced time of step 23 is 1 minute. Thus, the specified time for the production of 6 weighting agents is 30 minutes. If all stages of dumbbell production are carried out in parallel, then the production time of one dumbbell is approximately equal to the duration of the longest production stage and is 30 minutes.

In this case, the total production time of a batch of 300 dumbbells will consist of the production time and the service time and will be 156 (300 * 0.5 + 2 + 1 + 3) hours, so the equipment maintenance time adds 4% to the production time dumbbells.

The claimed solution provides precise control of the use of equipment, which allows efficient maintenance of equipment, avoiding breakdowns or excessively frequent maintenance.

Since within the framework of this decision each product is labeled, then during quality control (output or intermediate), it is possible to determine what level of quality each of the involved employees provides. Based on this information, a decision can be made on the need for training for workers with low rates, the implementation of measures to transfer experience from workers with high rates, decisions on remuneration, etc. have been made.

Moreover, statistics for each employee can be obtained for each operation performed by him, since during each operation all relevant information is recorded and stored, including the name of the employee, the equipment used.
