    This article aims to present the principles of the method of genetic algorithms and examples of the use of this method for solving problems related to proper organization of evacuation both from ships and land buildings. The paper also proposes the use of genetic algorithms to search for the optimal distribution of evacuation. The problem of course was brought to the task of evacuation transport, which is so designated evacuation routes for different groups of people to get the shortest possible evacuation time. Application of genetic algorithms will determine the most preferred target as passengers from the premises where they are located at the start of the evacuation to the assembly. Describes how to encode the problem in the genetic algorithm and a simple calculation shows the distribution of escape routes and validate the assumed method of encoding

    The paper presents an idea to utilize crankshaft’s angular speed variation and its derivative for monitoring of trouble of Diesel engine combustion quality. Measurement of instantaneous angular speed, recording and archive of values is easy to obtain using optical indicator and programmable logic controller. Advantage of this method is simple installation and constant signal. Collected data can be processed on board, basing on MS Excel formulas. Observation of changes of instantaneous speed and acceleration can not replace more accurate monitoring systems like Main Effective Pressure measurement or vibration monitoring, but is an excellent tool for early warning. When a signal about deteriorating of engine performance is obtain, more accurate diagnostic can be implemented. Expected final result will be elimination of engine’s cycle’s irregularity. Proposed method is at early stage of investigation and further steps to prove its utility and to develop concluding rules are to be conducted. In the paper are presented preliminary analysis of some bunches of data collected from two bulk carriers, operating in similar condition

    In the paper the evaluation of applied solutions, as well as the operational parameters in context of achieved efficiency of steam cycle of a supercritical power plant was carried out. The analysis for the referred structure of a power plant was made. The thermodynamic computational model was created in GateCycle software. In the calculations, the basic assumption was the maintenance of constant gross power of power plant. For this purpose, in the model the flow of live steam entering steam cycle was changed. In the first step the assumptions for three cases of unit were determined. First of all, the variants differ from each other with live and reheated steam parameters. The parameters for the two examined cases can be regarded as possible to be currently achieved in a modern supercritical power plants, while the third case represents a perspective variant. Based on relevant data implemented into the computational model, the relevant results for quantities characterizing the operation of examined units were generated. Among others, in the analysis the values of following quantities were determined: steam cycle efficiency, gross overall efficiency and specific consumption of heat. In the paper the assumptions, as well as the results are shown in the form of tables. The conclusions from comparison of results for individual solutions are also formulate

    Using the example of one section of a railway line, the effect of various factors on breaks in train service has been analysed. The types, number and duration of breakdowns, as well as their influence on both passenger and goods trains service have been specified. The traffic capacity of a railway line is related to the possibility of meeting the timetable, which is therefore affected by all breaks. It is very important to know the type of breakdowns, their number and influence on a railway line capacity as well as their causes

    This paper presents a part of the results of the research carried out by its authors in the framework of a research project “Analysis and evaluation of the level of adjustment of entrepreneurs and OSH specialists from the region of Łódź to the changes in legal provisions and in market needs”. In the framework of the project 200 OSH specialists professionally active in the region of Łódź were interviewed. The evaluation of the level of knowledge of OSH specialists and the analysis whether or not there are any differences in it depending on the level on which they obtained their vocational qualifications, on a secondary or on a tertiary level, was the main aim of this analysis

    The operation of vessels is more and more accurately monitored and collected information allows for rationalization of decisions related to maintenance of technical assets. The article defines a universal maintenance performance indicator (UMPI) using methods of numerical taxonomy. It was reviewed the purposes of use of performance indicators (KPI – Key Performance Indicators) and suggested to apply a universal indicator, connecting different groups of information and allowing ranking of technical objects according to multicriterial evaluation of maintenance performance. There is an example of application of universal indicator, which was calculated for a hundred of technical objects recognized by the vessel’s shipowner as critical in the system of operation. The results allowed to rank objects from the best to the worst maintained according to multicriterial evaluation. It was defined the direction for further research on a universal indicator of maintenance performance

    In Polish conditions, one of the types of investments which bring financial benefits for the investor and also reduce the load of the environment is thermal insulation. This article shows how to make an evaluation of sample of investment, which is the thermal insulation of the exterior boundary walls, from the financial side. Indicators to assess the investment in ecological terms, using life cycle assessment LCA are also proposed. An analysis of different options depending on the thermal insulation was made. Analysis includes: properties of the exterior boundary walls against thermal insulation, the type of thermal insulation and type of heat source in the building

    In the article research analyzing the level of the economic knowledge of adult Poles was described. Analyzing both subjective, measured with the scale of self-assessment and objective, through the test of message, aspect of the knowledge to economic themes. The test included three groups of issues: 1) acquaintance of current economic indicators and selected public charges, 2) define basic economic notions, 3) understand the relation between individual economic phenomena. Obtained data shows, that the examined group of adult Poles has on the average level knowledge, however not-allowing to full understand principles of free economy market functioning
