Crisis management is at the time of dramatic changes external settings to current issues. In today's tough competitive setting we can assume that organizations will increasingly compete for the most able employees who continue to deepen their knowledge, which are able to use not only normal but also crisis management. The managerial competency consist of skills and abilities contribute to the excellent performance of crisis managers. Crisis manager must be a strong managerial personality is able to cope with mentally and physically demanding process recovery company. Crisis manager has to deal with crisis situations well, it is necessary to constantly develop their managerial competency.

Rubber–textile construction of conveyor belts is widely used in various continuous transport systems. Due to the fact that complex carcass is vulcanised, its observation and analysis are very difficult to perform. The methods used so far have been based on its violent extracting, often accompanied with the formation and existence of defects. Such an analysis does not allow distinguishing between defects caused by operation of the belt or defects caused by the process of extracting itself. This paper aims to verify a new approach to examining the inner carcass of rubber–textile conveyor belts with a focus on the possibility to obtain information about its condition. This has not been possible with the methods used so far. The main focus is on the measurement of distance between the individual fibres in the warp and weft of the carcass, and simple size analysis of the identified defects. Presented results prove that the method of industrial tomography clearly identifies the defects in the conveyor belt carcass. The method enables the identification of single fibres, punctures and separation of individual layers.

Simulation software Tecnomatix Plant Simulation was originally created for a modelling and subsequent simulation of production and logistics processes. Its variability, however, opens its use also in other areas such as transport in urban agglomerations. Based on that, research was implemented to verify the program’s application in urban transport, specifically to visualize and simulate traffic processes at the traffic node. The paper describes a methodology which made it possible to create a simulation program for traffic light intersections, and presents examples of the simulation model application. The proposed methodology will enable the application of Tecnomatix Plant Simulation to create a complex simulation model of the logistics process. It will mainly enable to simulate the field of production logistics and city logistics within one simulation model.

The use and operation of crawler cranes in the Czech Republic is dependent on the availability of several major producers (Liebherr, Caterpillar, Volvo, Sennebogen, etc.) and Czech producers (Unex Uničov with its successor ND LOR Uničov, Tatra and others). The authors of this article explain the problems of operation, repairs and risks of failures in specific types of crawler cranes supplied by Liebherr during their operation in the steelmaking company Třinecké železárny, a.s. and Trilet Ground Services, a.s., the company specialized in renting machines that are used for foundations of buildings. The article proceeds from the evaluation of the operational data of both delivered and repaired machines and the data obtained from the repair company needed for the commissioning of the serviced machine, as well as the frequency of repairs during the specified hours of work within the course of operation of the machines. The processed data serves as a basis for the evaluation of risk of possible failures when using machines. Risks are evaluated using the FMEA method.

Compliance with the principles of occupational safety and health is one of the preconditions for avoiding emergency events. Without a doubt, this is one of the underlying duties of every employer or operator of waste recycling centers. The risk to health resulting from an orphan source of ionizing radiation in the form of scrap metal is quite high and can affect a significant number of people. As part of the precautions relating to employees, the employer must analyze the risks associated with working with scrap metal and emphasize the possibility of any previous contamination. In practice, various methods and procedures are used to assess the risks at scrap metal collection facilities, which are mostly based on the knowledge and experience of their inspectors. However, this is not usually done by means of appropriate risk analysis methods, which is the main disadvantage. The goal of this article is to point at the risks related to discovering an orphan source of ionizing radiation by using the Ishikawa diagram and the point method. Furthermore, this article also deals with the demarcation of a safety zone with respect to the protection of health and the environment. The specification of risks, the proposal of recommended precautions, and the expeditious demarcation of a safety zone in the case of the intervention of fire brigades in order to protect and/or decontaminate the persons are also included. Doi: 10.28991/CEJ-2022-08-11-013 Full Text: PDF
