(National Аviation University, 2020-12) Mamchur, Vitalii Volodymyrovych; Мамчур, Віталій Володимирович
Due to the steady growth of consumer needs, companies are forced to increase their productivity. At the same time, they face a number of problems, among which are the deterioration of quality and optimization costs, as well as the growing consumption of human resources. Production automation systems can solve the above difficulties, as well as open new frontiers of productivity. Production automation is a process in which previously performed human control and management functions are fully transmitted to automatic devices. very often automation is confused with mechanization. To avoid confusion, it should be remembered that mechanization is the simplification of human work through the use of automated equipment, and production automation is the use of an automatic system to control and manage the entire process. in other words, automatic control systems (ACS) exclude the presence of a person during operations and control the stages of execution.

(National Аviation University, 2020-12) Lebed, Nataliia Volodymyrivna; Лебедь, Наталія Володимирівна
Long before the advent of computerized databases, humanity already then had a need to store information in a structured form. Since at a time when computers either did not exist at all, or they were just entering the market and were at the stage of their formation, peculiar databases existed in written or physical form, for example, data archives, reference centers, libraries, ledgers, telephone directories etc. And since now there is a need to store huge amounts of information, while taking up as little storage space and resources as possible, databases are an integral stage in the development of opportunities to simplify the life of mankind. The database is both a tool and the very subject of a collection of data, which shows the state of certain objects and their relationship in a certain subject area.

With the growth of enterprises, it becomes more difficult to competently manage them. This means an optimal and balanced approach to production, in which it will give the best results. In addition, it must be competitively capable, otherwise even perfectly adjusted production will incur losses. That is, it must either be of better quality than the products of competitors, or, with the same quality, there must be a cheaper production in order to be able to have a lower price and then benefit from intercepting customers. The task of finding the best way to do business is at the heart of all systems focused on planning and organizing enterprise resources. Such a system provides a business process processing model that covers almost all aspects in production: planning orders and deliveries, deliveries to the warehouse and shipments, movements in the warehouse itself and inventory in general, that is, up-to-date data on the availability of the necessary materials. Supply and demand planning is key to running any business because it is the starting point of all processes. Based on this information, all further production will be formed with the purchase of materials, storage, processing and dispatch to the buyer. Such systems tend to cost fabulous money. As practice shows, the program will generate income, but this will only happen in the long term.
