Operational control of probabilistic processes in a multi-stage specialized system

Abstract

A process consisting of sequential operations is considered. For each operation, you can determine the currently available probability of its error-free (high-quality) execution. By the qualitative performance of the operation, we will understand the achievement of a given level of quality in quantitative proportion to the overall level. The purpose of the article is to build a quality management strategy in which a set of probabilities of quality levels not less than a certain threshold value is achieved, with minimal costs for carrying out appropriate measures. The article presents the decomposition of operations into activities; classification of activities into activities with conditionally linear or asymptotic response; quality assessment in a multi-level control system with response functions of various types; optimization problems and their algorithmic solutions.

Development and investigation of algorithm for the synthesis of an automatic control system of the drying process

“…On the other hand, it is clear that the regulatory effect 𝜐𝜐(𝜏𝜏) tends to zero when 𝜏𝜏 → +∞, since the astaticism of the system is ensured by the regulator 𝑟𝑟 𝑟𝑟 of the thermal channel. So, the impact will have a damping impulse characteristic when 𝜏𝜏 → +∞ [10,11].…”

“…where 𝑀𝑀 is variability, and |𝛷𝛷(𝑗𝑗𝜔𝜔)| is the modulus of the amplitude-phase-frequency characteristic of the closed system, can be written as follows [11]:…”

“…Therefore, it is interesting to study how the roots of the characteristic equation on the s-plane are shifted when any parameter of the system changes. The location of the roots of the system on the s-plane can be determined graphically, by the so-called root hodograph method that is an effective tool in the analysis and synthesis of ARS [11,15].…”

“…Figure 4 illustrates the characteristic hodograph of the roots of equation ( 11) of the single-channel speed ARS of residual moisture of apples, for the construction of which and subsequent selection of the roots, the rlocus and rlocfind functions of the Matlab program have been used [11,12,15].…”

Investigation of communication parameters based on monitoring and statistical modelling

“…This necessitates choosing the appropriate method for the set specific goal and ensuring the stability and stability of the designed network [1]. The main tasks that should be solved could be described as following:  investigation of computer data processing [2];  architectural organization of the network infrastructure;  investigation of the system characteristics of node subnets;  analysis of network traffic and routing parameters [3],  investigation of remote access to distributed resources in the digital space [4];  specifying the level of service of user requests, etc. Each of them reflects on the correct maintenance of information resources in the network environment (network directory, files and databases, user mailbox, Webpage for presentation of information, etc.).…”
