THE IMPROVEMENT AND AUTOMATION OF THE PROCESSES OF THE PRODUCTS RECEPTION AND ASSEMBLY IN THE TRADE-WAREHOUSE COMPLEX

2018, vol. 18, no. 4, pp. 160–169 160 Introduction. Statement of the problems The warehousing operations in the activities of any company are very important and require much attention and research. Especially in this activity it is possible to single out the processes of receiving and assembling goods, since every day it is necessary to continuously consider hundreds and thousands of goods. The assembly is complicated by the fact that different types of goods must be completed in one order. If you do these operations manually, this leads to shortages, delays and re-sortings. Receiving goods manually causes theft, improper placement by warehouse storage areas, and slows down the work process. These errors lead to a loss of funds and the company's time, are forced to come back again and again to correct them. Immediate impact on them has a human factor, the lack of automation of the processes of receiving and assembling goods, accounting for goods in the warehouse. Therefore, the solution to the problem of improving and automating the process of receiving and assembling goods in the trade and warehouse complex is an urgent issue [1]. DOI: 10.14529/ctcr180416

The logistical processes of the enterprise require constant improvement and introduction of corresponding changes. The study of the activities of the trade and warehouse complex showed that the main role is played by the system for managing the processes of receiving and assembling goods. Therefore, in the article, special importance is given to the process of automation and development of information support for a system for managing these data in the trade and warehouse complex.
The analysis and modeling of the existing processes of the company on the basis of two approaches of business modeling has been carried out. It is shown that the object approach allows to build a more stable to changes system, has more correspondences with the existing structure of the organization. The article presents that the functional modeling is optimal when the organizational structure undergoes changes or is in the process of correction. Using the graphical language IDEF0, the analyzed system is represented as a set of interrelated functions (function blocks).
To improve the efficiency of storage processes, based on the AS-IS model, a TO-BE model was built and the efficiency of the developed model was evaluated. During the TO-BE model study, the advantages of the embedded device for automating the processes of receiving and assembling goods were proved, as well as the advantages of the new model in terms of key indicators: the time of work, labor productivity, costs, the number of errors in the assembly of goods, the number of staff.
The substantiation of a method of automation of warehouse processes of reception and assembly of goods is presented, the choice of the brand of the device of trade and warehouse activity is made. To illustrate the choice of software, basic software platforms were considered and optimal software was identified to ensure the efficiency of warehouse processes. The choice of software was made taking into account the possibility of integrating the data collection terminal with the 1C system used in the company's work. The capabilities of the selected driver, its advantages and functional properties have been analyzed.
Keywords: information support, automation of warehouse processes, trade and warehouse complex, logistics processes.
In order to decide the above-mentioned problem, the following problems have been defined and solved in the article:  the analysis of the company's activities, its organizational structure, regulations and processes in the logistics department has been performed;  the AS-IS model of the logistics process and the decomposition diagram of the AS-IS model of receiving and assembling goods in the warehouse has been built;  to improve the efficiency of storage processes on the basis of the AS-IS model, the TO-BE model has been constructed and an evaluation of the effectiveness of the developed TO-BE model has been presented;  the method of warehouse processes for receiving and assembling goods is justified the selection of software (software) is made [2].

The analysis and the modeling of existing company processes
More details on the activities of the logistics department, which is carried out on the territory of the trade and warehouse complex (TWC). Warehouses are an important element in TWC. A rational approach to the implementation of warehouse operations is the key to the profitability of the entire trading and warehousing complex. Therefore, organizing the logistics process, it is necessary to pay attention to such factors as:  the rational layout of the warehouse with the allocation of working areas, which contribute to the improvement of the process of assembling and receiving goods;  the effective use of space in the storage room when arranging racks and shelves for storage;  the use of special equipment that is capable of performing various operations, which makes it possible to reduce the number of lifting and transporting machines;  the reduction of transportation routes inside the warehouse, which allows to reduce the throughput of the warehouse, etc.
To build the functional model of AS-IS it is customary to use two approaches to business modeling. Each of them has its own advantages. The object approach allows to build a more stable to changes system, has more correspondences with the existing structure of the organization [3][4][5]. Functional modeling is well suited when the organizational structure is subject to change or is in the process of adjustment. The approach of functions is better understood by performers when they receive information about their work at the moment.
Using the graphical language IDEF0, the analyzed system is presented to analysts and developers as a set of interrelated functions (function blocks). As you know, modeling with the help of IDEF0 tools is the first stage in the study of any organization system [6].
After the construction, the context diagram is detailed using the first-level decomposition diagram. Detailing the business processes allows you to identify the shortcomings of the organization, even where functionality at first glance seems obvious. Decomposing the main block of the diagram, the following important processes are distinguished: company management; logistics; accounting and finance; purchase; marketing and sales. Fig. 1 shows the decomposition diagram of the AS-IS model.
Thus, the most important processes requiring automation, such as the receipt of goods and the assembly of goods occurring in the logistics department, are identified in the analysis of the efficiency of existing processes, based on the AS-IS functional model and the AS-IS decomposition model. Also, the minuses of the AS-IS model in these two processes have been defined processes: 1) in the process of acceptance of the goods at the stage of registration of the invoice in the 1C system, the expiration dates, invoices, dates, full names, the number of the consignment note, etc., are manually entered; 2) in the process of assembling goods, all assembly notes are on paper, the data on the executors and the list of goods on the waybill are marked manually, then they entered into the program by the operator; 3) there can be re-sortings and shortages, because Large amounts of work entail errors when searching for the right product; 4) reduced speed and productivity of assembly of goods on consignment notes due to the presence of human factors; 5) there is no control over the correct placement of goods received in the warehouse [7]. Thus, we propose a solution and construct TO-BE model based on the identified shortcomings.

The description of TO-BE functional model and choice of equipment
The analysis showed that one of the solutions to the identified problems and the most economical from the point of view of automation of the processes of receiving and assembling goods will be the introduction of the data collection terminal (DCT) into the logistics department. The main purpose of the DCT is the quick and convenient collection, processing and transmission of information about the cargo or goods in the company's information system, as well as the use of bar coding [8].
There are different categories of data collection terminal. Each of the categories of terminals for data collection has certain constructive and functional features that make them the best kind of devices in these conditions. Selecting a particular type of terminals follows, clearly presenting the conditions under which it will be used.
During the study of the TO-BE model, the advantages of the embedded device for automating the processes of receiving and assembling goods were revealed: 1) the work time of the employees using the DCT is reduced; 2) the labor productivity is increased; 3) with the disappearance of paper carriers, the cost of paper is reduced; 4) with the elimination of the human factor, various constant errors of employees are disappeared.
TO-BE model has been formed based on the study of the AS-IS model and the processing of its shortcomings (Fig. 2). The decomposition of the logistic process of the TO-BE model is presented in Fig. 3.
As a result of comparing the AS-IS and the TO-BE models, the advantages of the new model are revealed, which are presented in Table 1. Thus, the introduction of AS-IS model increases the labor productivity, cuts the paper costs by half (since paper carriers disappear for assembly), eliminates the human factor (which reduces the likelihood of errors in the assembly of goods on invoices), reduces the required number of personnel (which allow employees to re-qualify for other types of work in the organization) and the most important advantage is the increasing the manageability of the warehouse.

The choice of software for the implementation of the trade and warehouse activities
The automation of the warehouse allows to ensure the most efficient management of all its processes. This approach serves as a guarantee of stable business development. The universal warehouse management automation system provides an operational accounting of products and detailing the placement of goods in warehouses. The list of tasks it implements also includes inventory control and correctness of product write-off, reservation management. Such a program is designed specifically for the management of warehouse logistics.
Automation of warehouse management is provided through the introduction of specialized software products. The software product will allow automating all existing processes in a short time. For the selection of software analysis of existing operating systems (drivers). The results of the analysis showed that the capabilities of the wi-fi data acquisition terminal driver are most suitable for working in the warehouse, since it is the only driver that works with 1C: Enterprise 8. Together with the software, manufacturers offer a set of maintenance treatments for the supported configuration [9][10][11].
The advantages of the software are: 1. There is no need to change the configuration of 1C. 2. The address storage. Each driver is supplied with a configurator (mobile development environment), which allows changing the processing logic of the documents and the user interface of the DCT, as well as developing the new operations.
3. The remote work. To work with DCT that are not connected to that particular computer on which 1C works, a wired version of the driver provides a special synchronization utility that copies files from the DCT to a computer with 1C and vice versa. In wireless versions of the driver, the exchange takes place directly over the Internet, by connecting via Wi-Fi or locally via the cradle (when inserted into the cradle, the DCT starts to see the network).
4. The automatic loading and unloading of documents in 1C. It can be possible to customize the selection to work on the DCT and automatically to download, upload, fill any warehouse documents 1C.
5. The teamwork with the documents. It is permissible the simultaneous work with one document on several DCT. 6. A free configurator (mobile development environment) is supplied with each driver, which allows changing the processing logic of the documents and the user interface of the DCT, as well as developing new operations.
7. Using the Mobile SMARTS 2008 platform, the mobile development environment is supplied with the driver, which allows changing the processing logic of the documents and the user interface of the DCT, as well as developing new operations.
8. The driver is protected by a software license, which is issued separately for each terminal in accordance with its unique code.
The additional functional characteristics of the driver are given in Table 2.

Conclusion
Based on the analysis of the shortcomings of the AS-IS model, the TO-BE model was built for automation of the logistics department and the goods reception and assembly processes, in which it is proposed to implement a data collection terminal. The models AS-IS and TO-BE are compared. The implementation of the TO-BE process increases the labor productivity, reduces the cost of paper by half, errors in assembly disappear, because the human factor is removed, the work time is reduced, the number of personnel is reduces, and the most important advantage is the increase in warehouse manageability.
The selection of software was made for the integration of the data acquisition terminal with the 1C system used in the company's work. The capabilities of the selected driver, its advantages and functional properties are described.
The requirements to the implemented equipment are revealed, such as: 1. The optimum cost of equipment.
2. The ease of use.
