Purpose: This paper aims to provide insight into currently available corporate operation and control management approaches through the examined articles, focusing on bottlenecks and closely related theories. Design/methodology/approach: The reviewed publications, which focus on the theory of constraints, different approaches, the concept of bottlenecks, and the presentation of related methods, bring us closer to understanding the changes that have taken place in the past decades. Findings: The immense impact of digitization and changes in demand affect the requests placed on companies; the way consumer needs are met has changed and accelerated, to which companies must adapt. In the case of services and products, the primary goal of manufacturers and service providers is to generate revenue and profit by satisfying consumer needs. For this, creating and maintaining an efficient operating system that does not contain restrictive elements is necessary. This publication provides a comprehensive overview of how the approach to the unified concept of the bottleneck is an effective tool for companies to improve their processes. Research limitations/implications: The current study analyzed some of the most relevant publications in the ScienceDirect database based on the keywords. This approach certainly serves as a beginning point for the understanding that to focus on the researched problem space, a systematic literature review is required. Originality/value: This study provides insight and supports the importance of a unified approach to identifying constraints for effective operational processes.

W artykule zaprezentowano zastosowanie termowizji do kontroli poprawnej pracy wentylacji naturalnej w mieszkaniach. Na podstawie termogramów wykonanych zimą w mieszkaniu oraz pomiaru prędkości ruchu powietrza przed kratkami wentylacyjnymi dokonano analizy działania wentylacji. Do celów analizy opracowano termogramy miejsc napływu powietrza do mieszkania (rozszczelnione okna) i jego odpływu (kratki wentylacyjne). Sporządzono też symulację ciągu odwróconego przez jeden z kanałów wentylacyjnych i termogramy takich przypadków. Przypadek wadliwego działania wentylacji naturalnej spotyka się często w budynkach mieszkalnych. Termowizja jest szybką metodą weryfikacji poprawnego działania wentylacji naturalnej. W przypadku nieprawidłowości umożliwia również wskazanie przyczyn niesprawności.

The article presents the use of thermovision to control the correct work of natural ventilation in apartments. On the basis of the thermograms made in the winter season in the selected apartment and the measurement of the air movement speed on the ventilation grilles, the ventilation operation was analyzed. For the purposes of the analysis, thermograms were made for the places of air inflow into the flat (unsealed windows) and air outflow (ventilation grates). The simulation of the reverse sequence through one of the ventilation ducts was also performed and thermograms of such cases were attached. This case of malfunctioning of natural ventilation is often found in residential buildings. Thermovision is a quick method to determine the proper functioning of natural ventilation. In cases of irregularities in its work, it also enables identification of the causes of its malfunction.

The increasing quality requirements and high level of automation in process engineering causes the need for continuous monitoring of many parameters important for the technological processes. Continuous monitoring of operation is of great importance, also in the broadly understood area of water supply. Along with the increasing environmental pollution, and accompanied growing scarcity of drinkable water and worsening of its quality, it is very important to monitor the performance of water treatment processes, physical, chemical and biological parameters of raw and treated water, and condition of water supply installations. Remote industrial monitoring becomes indispensable for water supply companies, at least because of their diffused infrastructure. Transfer of data between specific technical objects is necessary for controlling their operation and for functioning of the entire water supply system. The experience related to operation of industrial monitoring systems points to their high utility value in both functional and analytical ranges. It may be stated that those systems fulfill their tasks, and their on-going development due to the progress in computer, measurement and remote transmission technologies possibly will bring measurable operational and economic benefits.
