The Czech Republic has been historically a major producer of engineering products that includes unique products, although their size usually exceeds standard dimensions or weight. These types of products have high value added and are important for export. In the heavy machinery it is e.g. mining and metallurgical equipment, and other components for installation of turn-key investment units. So called light engineering also produces machinery and equipment, which can be categorized as oversized items. Locations with manufacturing plants that produce products for the chemical industry. Energy and also the automotive industry are located all over the Czech Republic. Important areas of production are especially the Ostrava region, the Pilsen region, The Central Bohemia region, the Usti region and also the South Moravian region.
The transportation of these oversized items is from logistical, transportation and organizational point of view such a complicated process into where not only a manufacturer and a carrier enter. Also relevant government authorities and other organizations are having high influence.
Although the transportation of oversized items is only a small part of the total volume of traffic to and from the Czech Republic, it is a very important part, specifically for export. It is necessary to pay a special attention to this type of transportation also in terms of possibility of using different transportation modes.
From 2004, the moment of entering Poland to European Union structure, there were numerous of projects completed which aimed on developing transport infrastructure. Some of them were supposed to build support TEN-T net, as well as on increasing regional development by creating investments areas, increasing life standards by better inhabitants mobility, decreasing unemployment rate etc. Over projects had financial support from EU founds.
The aim of this paper was to describe the projects supporting development of airports in Poland. Author focused on the increasing passengers throughput which was assumed when apply for EU founds. This assumptions were compared with current (2015) use of airports. Based on this the effectiveness of the investments is presented.
Existence of waste is the result of a problem with the management of material flows – both forwards and reverse. Elimination of waste begins in the product and production and delivery processes design phase and incorporates the entire product life cycle including reverse logistics and decision making for the final disposal. Reverse logistics thus should work closely together with waste and innovation management to share information about the origin, existence and character of waste due to the potential utilization of any residual value in waste and for potential improvements in product and process design or new product and process development. The purpose of this paper is to show the differences between the firms that use and that do not use waste as the idea for product innovation resulting from the survey of reverse logistics management practices of the Czech firms set in the broader context of several management issues. Results indicate differences that might have managerial implications, e.g. knowledge and quality management relationship to the utilization of waste as inspiration for innovation.
Research in reverse logistics was previously focused mainly on manufacturing enterprises and on tangible reverse flows. However, with steady increasing proportion of services in GDP and with servitization of products, direction of further research in reverse logistics could aim on service sector and on intangible reverse flows, i.e. on information. The concept of gathering information from and about customers is not new and has been investigated by marketing researchers for a long time. Nevertheless, information about (dis)satisfaction of customers, their experience with products or complaints was gathered mainly in order to increase satisfaction, improve the experience or reduce the number of complaints. As one of the main purposes of reverse logistics is to reduce physical flows, among others faulty products or services, this can be done by designing better products or services. Therefore, the purpose of this article is to analyse the current research that focuses on using information from customers to reduce reverse flows and design conceptual framework of tools, methods, and reasons what, how, and why the feedback is gathered. Using the designed framework, suggestions for further research in the area of reverse logistics of information in services are discussed.
The article discusses the basic characteristics of multiversion production and also presents the problem of production of different product versions on the same production line. The car production is selected as an example of the multiversion production process and the three main branches of the production plant are characterised. There are: body shop, paint shop and the assembly line. For each of the branches of the car production line the optimisation goals, adequate to the production stage, are discussed. Basing on exemplary manufacturing process, it is presented, how determining proper sequence of tasks carried out in the production system may affect production optimisation. This paper presents a problem of sequencing cars, known from the literature as Car Sequencing Problem (CSP). The problem, was widely considered and simplified in the competition ROADEF Challenge 2005 organised by the French Society of Operations Research and Decision Analysis. In this article is also presented the range of reduction of CSP problem relative to the problem occurred on real production line. For comparison the structure of an exemplary industrial plant is shown. Basing on the presented scheme of the cars production, the importance of use of the buffer warehouses in selected production system is highlighted. Thus, it is given the suggestion to reformulate the CSP issue. In the final part of the article, a sample method of optimisation of analysed production process is presented, focusing exclusively on paint shop. This method aims to provide a minimum number of changeovers of robots painting car bodies, what by minimising setup times, increases the number of produced cars. It also has impact on minimising the consumption of paint and solvent used to clean the nozzles of robots whenever a changeover occurs.
The study focuses on increasing the efficiency of logistics flows in the health sector (waste streams drugs, records of medical examinations ...). Based on the interconnection of knowledge in the field of logistics supported by lean healthcare and their application to the analysis of process bottlenecks we try to eliminate not added value. Next we are to continue monitoring the use of information technology while ensuring quality, safety and legal processes. We monitor the process mapping, process optimization and the use of information technologies for effective management of logistics flows in health care. We also deal with increased safety and efficiency of logistics processes in hospitals.
