Abstract:

Uncertainty is an unavoidable element in many practical production planning and scheduling environments. The problem is formulated as follows. There are many tasks. The task is understood as any type of work within the technological process. Many machines must be used to complete a particular task. The execution of each task on a machine is characterized by indefinite time. In accordance with the technological process, a technological route representing a sequence of machines is prescribed for each or for some works. For practical use, methods using genetic algorithms are used to support plann

This research proposes a super encryption method that combines two cryptographic algorithms, namely Rabin Cryptosystem and Paillier Cryptosystem, to increase digital image security. Rabin's algorithm does not have homomorphism, so it is vulnerable to factorization attacks if the prime numbers used are too small. Meanwhile, the Paillier algorithm has homomorphism properties which allow arithmetic operations to be carried out directly on the ciphertext without decryp

Abstract:

In direct digital control (DDC) systems, computers replace traditional analog control devices. Direct digital control systems not only more efficiently perform the functions carried out by analog control devices but also provide new opportunities for increasing control flexibility, such as reprogramming to achieve the required control effects. The principles of developing di-rect digital control systems are described using the example of systems for regulating the tech-nological parameters of rolling. Both analog and discrete automatic control systems (ACS) are used to control mechanisms and e

Relevance. Lumber drying is associated with high risks of obtaining a low-quality or even unusable product. The problem under consideration has a number of reasons, both in violation of the technological process and in incorrect settings of drying mode parameters at different stages. The procedure for automated adjustment of parameters is usually associated with a linguistic assessment of the quality of the product, according to which a decision on adjusting the parameters should be made, taking into account signs of a violation of the technological process.
