Fire Extinguishing

For successful fighting large fires, it is required to develop new and improve existing decision-making mechanisms with the objective to increase the efficiency of actions of the involved fire-fighting units. When making decisions, the fire extinguishing manager must consider the efficiency of possible solutions. Assessment of the efficiency of each possible option is predictive and depends on the system of criteria used. The decision-making process in such conditions is associated with the use of formalized multi-criteria selection procedures, which, in fact, implement multi-criteria optimization. When choosing a multi-criteria solution, the fire extinguishing manager proceeds from his subjective ideas about the importance of the tasks to be solved at each site. Therefore, it is advisable for each fire protection object to develop its own management decision support system that allows to implement multi-criteria optimization based on the preferences of the fire extinguishing manager. The chosen solution option should ensure that several goals of the fire control system are achieved at once. Methodology is considered related to multi-criteria assessment, which can be used for an objective study of the actions of personnel to extinguish a fire for using them rationally in future. The proposed multi-criteria model for making managerial decisions makes it possible to study a wide class of problems of supporting the control of the fire extinguishing process based on the results of monitoring the actions of fire-fighting units. Practical application of the theoretical results in the form of a management information support system allows reducing the subjectivity and improving the efficiency of the management decision-making process when extinguishing fires.

The constant growth of recoverable volumes of oil and gas, the increasing remoteness of fields from developed infrastructure, political pressure and regulation, the development and complication of the technologies used, and the ever-growing volume of information create multilevel decision-making systems in the oil and gas industry. The further socio-economic development of not only individual corporations and regions, but also the state as a whole, depends on rational and timely decisions made in this area. The article is devoted to the development of management decision-making tools in the oil and gas industry. Peculiarities of the process of making managerial decisions in this industry are identified, associated with special geographical restrictions, the large disunity of production facilities and control centers, the difficulty of obtaining reliable information about the resources mined at great depths underground, market volatility and political influence. A methodology for making managerial decisions is proposed, consisting of three stages, each of which uses a specific set of tools. Five elements are identified that can be identified in almost all decision-making situations. It is shown how the preferences of the decision maker form a hierarchy of goals and values.

Introduction. The article substantiates the use of the depth of fire extinguishing by fire-fighting hoses for estimating the possibility of localization of fire in the management of combat operations in residential buildings. On the basis of the criterion in a generalized form a block-scheme of the generalized algorithm of the decision-making support of the fire extinguishing manager, which makes it possible to determine the possibility of localization of the fire by the available water fire-fighting hoses, is offered. A theoretical substantiation of the value of depth of fire extinguishing with direct fire-extinguishing jets in not-large squares of rooms and a functional dependence of the depth of extinguishing on the water pressure before the fire hose nozzle, which raises the calculation accuracy, is given. Goals and objectives. To evaluate the possibilities of localization of the fire by the available means and, as a whole, to increase the efficiency of fire-extinguishing management by the fire-division in the multi-story dwelling buildings. Increasing the calculation accuracy of the depth of fire extinguishing. Methods. Using the depth of fire extinguishing as an efficiency criterion in estimating the effectiveness of fire fighting with water fire-fighting units. The comparison of the actual value of the criterion with the required value determines the possibility of localization of the fire. Conclusions. The use of extinguishing depth as a criterion of effectiveness can serve as a basis for new methods and models to support the management decision-making of the fire extinguishing manager. The depth of fire extinguishing can be calculated as a function of the head before the nozzle of a fire-brigade can be used as a criterion of efficiency of the management of a fire-unit armed with water fire-brigade. Key words: fire, management, decision-making support, algorithm, efficiency criterion, depth of fire extinguishing.

Abstract Saturation logging tool is one key tool that has been successfully used in the Oil and Gas Industry. As important as the tool is, it should not be mistaken for a decision tool, rather it is a tool that aids decision making. Because the tool aids decision making, the decision process must be undertaken by interdisciplinary team of Engineers with historical knowledge of the tool and the performance trend of the candidate well and reservoir. No expertise is superior to historical data of well and reservoir performance because the duo follows physics and any deviation from it is attributable to a misnomer. The decision to re-enter a well for re-perforation or workover must be supported by historical production and reasonable science which here means that trends are sustained on continuous physics and not abrupt pulses. Any interpretation arising from saturation logging tools without subjecting same to reasonable science could result in wrong action. This paper is providing a methodology to enhance thorough screening of candidates for saturation logging operations. First is to determine if the candidate well is multilevel and historical production above critical gas rate before shut-in to screen-out liquid loading consideration. If any level is plugged below any producing level, investigate for micro-annuli leakage. All historical liquid loading wells should be flowed at rate above critical rate and logged at flow condition. Static condition logging is only good for non-liquid loading wells. The use of any tool and its interpretation must be subjective and there comes the clash between the experienced Sales Engineer and the Production/Reservoir Engineer with the historical evidence. A simple historical trending and analysis results of API gravity and BS&W were used in the failed plug case-study. Further successful investigation was done and the results of the well performance afterwards negated the interpretation arising from the saturation tool which saw the reservoir sand flushed. The lesson learnt from the well logging and interpretation shows that when a well is under any form of liquid loading, interpretation must be subjective with reasonable science and historical production trend is critical. It is recommended that when a well is under historical liquid loading rate, until the rate above the critical rate is determined, no logging should be done and when done, logging should be at flow condition and the interpretation subject to reasonable system physics.

On the basis of analysis of existing approaches to the process of decision making, in this article the procedure of taking optimal operational decisions is proposed, which describes in detail all of its aspects and features related to the specifics of the operational activities of transport enterprises. In this procedure the basic steps are those directly related to the modeling: formulation of the problem (formalization of the original problem), construction of the model, its solution, credibility and adequacy check, restoration (or adjustment) of the model. The object of the research is decision-making process in the operational management of transport enterprises. The purpose of the research is to develop a procedure for the process of making optimal operational decisions based on existing approaches to the decision-making process, using modeling as a scientific tool to substantiate them. The research method is methods of system analysis and modeling. It has been discovered that the need to reduce the subjectivity of the process of making important decisions in the operational activities of transport enterprises and increase its scientific validity is especially relevant today, in the face of threats and uncertainty about the external environment of the organization. All methods of rational decision-making are based on models, which, in turn, are scientific tools. Modeling creates a serious informational and methodological basis for structural analysis of decisions needed to improve the management process for operational managers and hence - to increase the level of management in general, because it makes them more systematic, and the tools used during this help them be more rational. The results of the article can be implemented during making complex and important management decisions in the operational activities of both transport enterprises and other business entities of various activities, regardless of the organizational and legal form and ownership.

Life insurance is a term used to refer to actions, systems, or businesses in which financial protection (or financial compensation) for life, property, health and so on gets reimbursed from unexpected events that can occur such as death , loss, damage or illness, which involves regular premium payments over a period of time in exchange for a policy that guarantees such protection. The term "insured" usually refers to everything that gets protection. Decision Support System is defined a system intended to support management decision making, Decision making is the main function of a manager or administrator. Decision making activities include identifying problems, finding alternative solutions to problems, evaluating these alternatives and choosing the best decision alternatives. The Vise Kriterijumska Optimazacija Kompromisno Resenje (VIKOR) method is one of the methods used in decision making. To use the decision support system method must have criteria that will be used in the determination, in addition it must determine the level of importance of each criterion. So the decision support system used must also have comprehensive and integrated planning to minimize the level of risk of failure and decision selection

The article discusses the issues of improving the efficiency of decision support activities on a relatively large amount of information. The research relevance is associated with the increasing complexity of control objects, which leads to a decrease in the efficiency of decision-making based on the personal experience of decision-makers, up to complete impossibility. The purpose of the ar-ticle is to analyze the problems faced by decision-makers and the creation of methods to improve the effectiveness of decision-making in typical situations. The article examines the main compo-nents of the intelligent subsystem of the decision support system, which require the use of analytical tools, and also forms the methods interaction structure necessary for the effective formation of sce-narios of information support for decision making. To achieve the goals, a decision support method based on an intelligent component was used, which is aimed at creating an effective infrastructure to sup-port decision-making; methods of identification and categorization, designed to implement the most accurate and correct comparison of the characteristics (state) of the observed situation and the characteristics of a typical situation stored in the knowledge base; correlation methods aimed at finding dependencies between the characteristics of situations and scenarios to solve problems associated with these situa-tions; a method for constructing subject qualimetry, used to form a predictive model to assess the degree of compliance of the selected scenario for solving the current situation. As a result, it was de-termined that an important aspect of decision-making in typical situations is the most accurate identification of the state of the situation, the choice of the best scenario for implementing the solu-tion for this situation and the analysis of the consequences of the selected set of measures. To solve these problems, a method for identifying a situation, a method for finding solution scenarios and a qualimetric method for predicting the effectiveness of the selected scenario have been formed. The article concludes that decision-making activities based on the accumulated experience can be im-proved by using the proposed methods and implementing a decision support system with an intelli-gent component.
