The EPC methodology enables accurate modelling of economic processes. One of the main spheres of its application is procedure creation under quality, occupational health and safety or environment management systems. The development of the methodology in question has led to establishment of precise conditions that must be conformed with in a correct process model. The main theme of the article is a general discussion of the EPC methodology. Based on an analysis of numerous literary studies published, a set of principles that should be met by an EPC diagram as a graphical representation of the process being described has been identified and discussed. Another subject touched upon in the article is the results of examinations of 156 diagrams from documents of integrated management systems implemented in two companies. The examinations conducted have implied that the diagrams created in the course of the documentation drawing up do not conform with many of the applicable requirements. The individual syntax errors occurring in the documents have been identified and discussed in the paper, and special attention has been paid to those related to application of the OR and XOR split connectors as well as those occurring when joining diagrams

To avoid the growth of organisms of different types on surfaces in a marine or freshwater environment usually coatings incorporating biocides (chemicals that kill organisms) are used. Instead of these biocide containing coatings there exist several approaches of nanostructuring the surfaces which prevents biofilm formation and bacterial adhesion as well as the attachment of larger organisms. In this paper results of a preliminary literature review on the potential role of nanotechnology in solving ecological problems concerning antifouling coatings are presente

Seaports play a very important role in the international sea-land transport chains and have a strong effect on the efficiency of foreign trade. As their influence on the regional economy and society is also significant, they face a high security risk. That is why they should be specially protected as infrastructural facilities of critical importance to the state. Moreover, protection of seaports constitutes and important element of the general concept of crisis management on local, regional and international levels. In recent years, both the European Union, by adopting the directive on enhancing port security, and the International Maritime Organization, by preparing the International Ship and Port Facility Security (ISPS) Code, have paid special attention to the protection of seaports against any incidents endangering their security. Vital among such activities is the preparation and implementation of a seaport protection plan and port facility protection plans. Those plans need to be consistent with the port critical infrastructure protection plan

The improvement of industrial enterprises requires a level of growth of enterprise innovation. The innovation at an economic scale has an influence on economic growth which is expressed by means of GDP per capita. There are clear correlations between innovation factors and a level of economic growth in the EU countries. The publication presents the analysis of chosen, mostly used innovation factors within an innovation influence side at level of prosperity in a given economy. On the basis of the gathered data, a model of linear regression describes dependence between innovation and GDP per capita. The situation of Poland has been examined in comparison with the other EU countries within a scope of innovation level in an entire innovation aspect, a contribution into innovation activity and innovation effect. The problems of the Polish economy in case of innovation effects, which are the lowest among the EU countries, have been also focused on in the following publication

The article presents a method of defining the required number of substitute technological objects used in the transport system, necessary for correct carrying out of the assigned transport task. The whole of the consideration was presented using the example of a chosen authentic system of the operation of transport means. On the basis of the identification of the authentic transport system and the means of transport operation process carried out in it, crucial operational states were designed as well as the possibilities of transferring between the particular states. Based on that, an event-centered model of the use of the means of transport was built, followed by a mathematical model of that process, assuming that its model is the homogenous Markov process. Then, for operational data obtained from research conducted in the authentic transport system, the values of the analyzed characteristics were defined. The presented results are a result of the research conducted as a part of a larger research project pertaining to the construction of a decision-making model of controlling transport system availability

The article presents a method for choosing technical objects to be used for execution of tasks by a control subsystem. The research object used to illustrate the discussion presented in the paper is a municipal bus transport network, in a given agglomeration. In order to solve the discussed problem the homogenous Markov's process has been accepted to be a mathematical model of the bus operation process. The ratio of the object's mean probability of being in its serviceability state to a time unit ,has been accepted as a criterion for choice (purchase) of a given make of the bus

In model investigation of ship’s fluidised bed boiler the similarity theory has been applied, which permits to transfer the investigation results from the model to the real object. For setting the non- dimensional numbers in similar phenomena, the analysis of differential equations describing the examined phenomenon or the dimensional analysis is applied. The article presents an example of the search for the non-dimensional numbers characterising the phenomenon of heat exchange in ship’s fluidised bed boiler

The growing ecological awareness of the society, implementation of European Union’s law and development of the market economy caused in the last years an increase in the interest in wastes that could constitute energy raw materials in the form of alternative fuels. This growth, however, is limited by factors, of which the main comprise disposal of a considerable waste quantity at waste dumping sites and a low level of waste recycling. Currently the production and utilisation of alternative fuels both in Poland and Silesia are insignificant. In 2006 in Silesia only about 20 thousand tons of alternative fuels, prepared from combustible wastes, were utilised. The possibility of gaining and application of an alternative fuel should be closely connected with waste management realised in the given area, and the producers of alternative fuels and the local heat-generating plants should be units cooperating with the remaining elements of the waste management system (dumping sites, segregation stations, fuel producers, distributors and deliverers). The increase in the utilisation of wastes as alternative fuels should be also one of the main objectives of the electrical power engineering industry. For a proper waste management in Silesia essential is to establish a system of logistic-technological solutions for the optimum production and utilisation of alternative fuels. In the paper essential aspects determining the construction of a complex system of production and utilisation of alternative fuels were presente

The increasing needs for carrying bulk cargoes between continents by means of marine transport have increased interest in the subject of safe carriage of these cargoes by sea. Soybean seed cake is one of many bulk cargoes, currently the best substitute of animal protein in the composition of fodder. As loose bulk cargo, soybean seed cake is carried by various specialist means of land and water transport. During transport by sea this cargo tends to pour athwart on board, in effect causing to shift the ship’s gravity centre and then a list favouring further pouring of the cargo, capable of causing the vessel to capsize. There has been presented the effect of selected transport and technological quality factors, namely static angle of repose, kinetic angle of repose and the size and shape of particles on the transport safety of soybean seed cake by sea. Research results have been depicted on graphs and described statistically

The problem of environment protection against selected properties of soybean seed cake in transport processes and the terminology of the dangerous cargo mentioned in various codes and regulations has been presented.
