The goal of every industrial enterprise is to make profits since it means survival in a tough competitive environment. This is also closely connected with achieving a certain level of performance that is carefully monitored through individual indicators. Financial performance indicators (e.g. relative indicators, absolute indicators, etc.) are particularly monitored. Non-financial performance indicators are also very important, however, only little attention is paid to them in enterprises. Some non-financial performance indicators can be expressed numerically, but in units other they can reflect factors which significantly contribute to the overall...
New Approaches to Designing Production System Structures
Rudy Vladimír, Peter Malega, Juraj Kováč
Acta Mechanica Slovaca 2019, 23(1):14-21 | DOI: 10.21496/ams.2019.008
This article is oriented on the new approaches to designing production system structures. It is divided into four main sections. First main section deals with philosophical aspects of production structure designs and their complexity. Second main section is about new approaches to designing customer-oriented productions and there are summarized technologies for viewing virtual scenes. Third main section treats with innovative process design in mechanical production and you can find their pillars of customer oriented production systems of the future. Fourth main section is oriented on production systems supported by design using virtual reality.
Digital Literacy of Employees in Production Process - Analyse of Production Stability and Productivity in INDUSTRY 4.0 Concept

Acta Mechanica Slovaca 2019, 23(1):22-29 | DOI: 10.21496/ams.2019.004
Important part of the higher productivity and effectiveness in today's industrial enterprises confronted with growing automation and digitization of production processes is strong connected with the ability of employees to be prepare communicate with newest digitized production technologies. Skills and abilities of employees influence radical the productivity, performance, value added of production flows. Presented paper analyse important parameters of digital literacy of employees in production processes and confronts the results with the core requirements on continuously process performance and improvement. Results achieved by presented analyse are...
Preliminary Product Design Based on the Cumulative Functions Concept
Tomáš Broum
Acta Mechanica Slovaca 2019, 23(1):30-36 | DOI: 10.21496/ams.2019.003
This article presents the new concept of cumulative functions and its use in the preliminary product design phase. The first part of the article concentrates on the cumulative functions concept. There is a description from the manufacturer's perspective of product functions followed by the customer's perspective of product functions. Combining these perspectives leads to the creation of the new cumulative functions concept. The second part of the article concentrates on preliminary product design, where the cumulative functions are used. It consists of three main parts: Morphological analysis, Crude design structures and Evaluation of product design...
Simulation Model Creation for Verifying the Production Capacity of a Production Line and Sizing in-Process Inventory

Acta Mechanica Slovaca 2019, 23(1):38-43 | DOI: 10.21496/ams.2019.005
The high complexity of logistical systems in connection with the high competitive pressure makes the implementation of efficient processes in companies and supply chains inevitable. Unlike the optimization in which an attempt is made to model a problem directly, analytically or through modelling using heuristic, the simulation tracks another, i.e. intuitive approach. The development of information technology has created the need to apply a comprehensive system of technical data management in industrial practice. It was necessary to increase the efficiency of information sharing within the value-added chain of the company on specific projects. The aim...
Analyses of Manufacturing System Matrix Structure for Preven-tive Maintenance using Computer Simulation
Sławomir Kłos, Justyna Patalas - Maliszewska
Acta Mechanica Slovaca 2019, 23(1):44-48 | DOI: 10.21496/ams.2019.009
The concept of industry 4.0 includes implementation of preventive and predictive mainte-nance of manufacturing systems. In the paper the matrix structure of manufacturing system is proposed that enables the implementation of production processes even in the event of manu-facturing resource failure. The simulation model of the system is prepared using Tecnomatix Plant Simulation software. The simulation experiments are conducted for different buffers capacities and availability of manufacturing resources. The simulation method enables to ana-lyze the impact of the failure of manufacturing resources on the throughput and average lifespan of products....
Work Measurement Study to Increasing Productivity of Production Line
Daniela Onofrejová, Jaroslava Janeková, Juraj Šebo
Acta Mechanica Slovaca 2019, 23(1):50-55 | DOI: 10.21496/ams.2019.010
The main goal of the paper is to propose solution toward capacity improvement of assembly process on a selected production line. The major content is focused on Basic Most method and its application in improvement process. There is a theoretical expectation that after applying Basic Most method to the assembly process, the capacity of production line would increase about twenty percentages. Motion and Time studies are often applied for improvements in efficiency of assembly processes. First, Process Screen method is used for gaining the information about process behaviour and its individual, partial and total duration. The final solution consists of...
Study of the Effect of Turbulence on Cooling Tower Wakes
Veronika Barraclough, Pavel Šafařík
Acta Mechanica Slovaca 2019, 23(1):56-60 | DOI: 10.21496/ams.2019.006
A subject of an experimental fluid mechanics task was measurement of flow around hyperboloid-shaped cooling tower. Experimental part was provided by means of 2D Particle Image Velocimetry (PIV). The contribution contains results from PIV measurements in a range of Reynolds numbers varying from 43000 up to 53000. The tunnels used for the measurement were two different types: Low Speed Wind Tunnel of Eiffel type (LSWT) with low rate of turbulence intensity and Boundary Layer Wind Tunnel (BLWT) with high rate of turbulence intensity.
