Abstract

In recent years lean thinking (also referred as slim) increases its popularity not only in industry, but also in the entire business world. There are many confirmed effects demonstrating the high effectiveness of this philosophy: a clear improvement of economic indicators, an increase in current satisfaction and the acquisition of new clients; better, stable quality of offered products and services; efficient organization of production; more effective management; high productivity of work and production; minimizing the costs of production and storage of stocks. Why is Lean implementation in our domestic conditions not easy and sometimes ineffective? In this study we will try to answer these very important questions.

Abstract

The article justifies the application of gas fuels for supplying auxiliary ship boilers. It presents legal regulations on maritime environmental protection areas and their requirements which are in power. It shows the chronology of introduced limitations on sulphur and nitrogen dioxide emissions and thresholds of carbon dioxide emission reduction expressed by EEDI (Energy Efficiency Design Indicator) and EEOI (Energy Efficiency Operational Indicator). Ways to decrease the values of EEDI and EEOI in the ship energy effectiveness management have been shown. Consequences of replacing marine fuels with LNG for running auxiliary ship boilers have been considered thoroughly, taking into account ecological, constructional, operational, procedural and logistic limitations as well as economic consequences. The summary shows the influence of particular consequences of using LNG for running boilers on the methods of maintenance of auxiliary boilers.

Abstract

Users in transport, forwarding and logistics companies use the mobile technologies for connect to existing information systems. By solving the ERIC Mobile project, these services will also be available on mobile devices. The article is aimed at lancing the requirements of all types of customers for the ERIC Mobile app. After the basic characteristics of the mobile device, the operation systems, the application development typology, the authors focus on the developing application “ERIC Mobile”. The aim of the article is to provide relevant requirements for further research and development of the software application of the rail freight information centre in Europe for end users of mobile devices such as smartphones and tablets.

Abstract

Transport is one of the human activities that increases the amount of greenhouse gases in the air. CO2 is the main cause of global warming and contribute for around 80 % of all greenhouse gas emissions. The paper presents CO2 production based on the amount of sold fuel in Slovakia and Slovenia. Based on the obtained data, the calculations about the production of CO2 according to the type of fuel was made. The conducted research has focused on the issue of traffic congestion and to reduce CO2 emissions by 15 % in total by 2030, as Slovakia and Slovenia concluded an agreement with other EU members in 2009. External costs calculation was made with average price of 1 tonne emission credit in 2016 and with presumed average price in 2019. The case study takes into account the consumption of the gasoline and diesel in transport throughout all Slovakia and in Slovenia.
