Risk is an inherent phenomenon of every human activity, of every social existence, of every human being. Risk is not coming into existence accidentally but is a part of incertitude and uncertainty that each entity is coupled with. Everybody shall judge what kind of influence has an occurring risk on his own action and what is its significance in a given while. In fact, human being lives in certain social and natural environment which also contains danger fragments. Therefore, it advisable to determine some rules how to evaluate possible risk situations. In this article some of possible solutions are interpreted.
Rules of Planning in Safety Management
Pawel Tyrała
Communications - Scientific Letters of the University of Zilina 2002, 4(4):13-18 | DOI: 10.26552/com.C.2002.4.13-18
The article aims to analyze the concept of crisis planning in civil defense system. Strategic plans are worked out by managers of the highest rank and define general aims of the organization. Elements of risk, threads, and ways of activity in crisis situation should be taken into consideration during strategic planning which is the planning of civil defence. Plans for civil defence are worked out in order to assignate and get ready for organizational and material enterprises of civil defence proper to real possibilities. They are prepared by state administration and local governments, factories and other units and institutions which are responsible...
Algorithm of Decision Making Process by Corporate Management and Ways of Resolving Crisis Situations Caused by Accounting, Financial and Economic Risks

Communications - Scientific Letters of the University of Zilina 2002, 4(4):19-24 | DOI: 10.26552/com.C.2002.4.19-24
The scientific paper presents an algorithm and methods of strategic decision making process by top management and ways of eliminating and resolving crisis situations caused by accounting, financial and economic risks. The algorithm deals with a business's lifetime stages and presents the risks, as well as the methods to analyse such risks, based on both external and internal factors of managerial environment. The aim is to define the risks and ways of eliminating them. The paper includes results of the EP 7260 (Brno, 1998-2000), GA MSM 431100007 (Brno 2000-2001)s and EP - 12/2001-2003 (Brno, 2001-2002) research projects. Methodology is based on analytical-synthetic...
Complex-Structure Resource Management in Engineering and Construction
Roman Marcinkowski
Communications - Scientific Letters of the University of Zilina 2002, 4(4):25-31 | DOI: 10.26552/com.C.2002.4.25-31
The original issue solved in this article is the model of analyzing hierarchical-structure resources ensuring controlling the availability and engagement of the resources in allocating units of a complex structure for given works. This model is applicable when designing the decision facilitation systems in planning military and engineer operations. "Qualifying" the units of such structures using the computer requires taking under consideration the fact of units "nesting" in others. Apart from the method of "qualifying" complex resources, in this work has been formulated a model of allocating a hierarchical structure for works on the separated work...
An Object Oriented Model of a Railway Safety-Related Control System
Karol Rastocny, Jiri Zahradnik, Ales Janota
Communications - Scientific Letters of the University of Zilina 2002, 4(4):32-39 | DOI: 10.26552/com.C.2002.4.32-39
There is a variety of methods and formalisms usable for writing specifications of railway interlocking and signalling systems or their subsystems. To write a consistent technical specification means to make a model with a required level of precision, clarity and economy of expression that is free of unknown spots and/or conflicts. One of possible formalisms suitable for making such models seems to be the Unified Modeling Language' (trademark of OMG). The paper presents experience and knowledge of authors who have worked over transcription of informal specification of a new railway interlocking and signallingsystem into the UML based object-oriented...
Communication in Emergency Situations
Anna Hlavnova, Vladimir Hlavna
Communications - Scientific Letters of the University of Zilina 2002, 4(4):40-47 | DOI: 10.26552/com.C.2002.4.40-47
Communication in emergency situations requires not only specific verbal but also non-verbal competencies of persons involved. Verbal communication comprises, apart from speech culture and the way language is used, also language competence which is to be properly applied in discourse. If language competence fails, non-verbal communication (body language) takes place.
Transport Provision of Evacuation
Miroslav Tomek, Miloslav Seidl, Lenka Rostekova
Communications - Scientific Letters of the University of Zilina 2002, 4(4):48-55 | DOI: 10.26552/com.C.2002.4.48-55
Risks of every person's life and property endangerment caused by natural disaster, technological average or social crisis are increasing. It is the reality of life that this danger can arise whenever and wherever, often even in unexpected situations. One of the most important tasks when solving any special situation is salvage of persons, animals and property from endangered buildings or areas. Evacuation provision and its actual realization are inseparable parts of this activity. This article deals with evacuation provision and solves its technical provision with a focus on logistic provision.
Exposition of Measure Risk within Quality Norms by Solving the Problems of the Persons and Property Patronage
Marian Mesaros
Communications - Scientific Letters of the University of Zilina 2002, 4(4):56-62 | DOI: 10.26552/com.C.2002.4.56-62
Qualitative norms at present being introduced into all sectors of management also enter successfully new sorts of managerial activities including safety management. Contractual safety interest of personal, material and non-material protected assets by means of a model process orientated protection meets fully requirements of continual improvements of managerial quality system of protection process.The aim of the article is to arrange logically the phases of the safety process development by means of accentuating existence of the private security service law, categorisation of individual parts of the hierarchy of the development of security services...
Architecture and Protocols for Robust NGN
Tatiana Kovacikova, Martin Klimo
Communications - Scientific Letters of the University of Zilina 2002, 4(4):63-71 | DOI: 10.26552/com.C.2002.4.63-71
Communication networks play an important infrastructural role in the crisis management. To fulfill this role, they have to be robust enough. The robustness is an aspect, which will have to be taken into account also in NGNs (Next Generation Networks). The paper introduces a reference model of the architecture and protocols for robust NGNs. Based on characteristics and requirements for the control architecture, it shows how the control layer can be decomposed, it identifies the basic network elements and the interfaces and protocols that might be used for their interworking. Based on the characteristics and requirements of transport and connectivity...
