Opis:
Technical cleanliness is at the centre of attention in more and more sectors of the automotive industry. Its importance primarily lies in the need to ensure the correct function of components and it is necessary to take into account that impurities can affect the assembly and proper functioning of other components if they are connected together in the working circuit. Requirements for technical cleanliness vary according to the type and function of components and can be divided into two basic areas – chemical cleanliness (for example, lubricant contamination) and particulate cleanliness (particles and fibres). So-called clean production must include all areas up until final assembly – production, assembly, storage, transport and the packaging itself. In process chains, measures are taken to minimise contamination or particle generation to achieve a continuous and controllable standard of cleanliness. A special section is the cleanliness of the cable connectors, which is dealt with in this article. The introduction describes the current state of science and research in this field and then summarises the standard requirements in the automotive environment and the basic possible consequences of connector contamination. This is followed by a case study showing the possibilities of preventing contamination by particles and fibres, including a discussion of the effectiveness of these measures.

Opis:
The aim of this research is to propose particular measures aimed at streamlining costs in terms of operations in a selected company. A specific proposal is based on the concept related to using services of the transport databank. As at least two out of five major carriers of the investigated company resell shipments to other carriers on such portals, the company could reduce the transport costs by entering shipments into the transport databank on its own. One out of three selected providers will be chosen using multi-criteria evaluation methods, specifically, the Analytic Hierarchy Process (hereinafter referred to as AHP) and the Base-criterion method. Determination of the weights of criteria will be carried out using the Saaty method of quantitative pair wise comparison and the Fuller pair wise comparison method. In this paper, the presented methods are applied for the example of a specific company specialized in the manufacture of metal storage racks and steel structures. In the Czech Republic, the company employs 65 employees in production, storage and administration. Based on the analytical evaluation of the current situation of the company, relevant measures will be proposed with a required effect on the effectiveness of such an enterprise.

Opis:
The objective of this contribution is the application of a new methodology for assessing connectivity in passenger transport regarding selected tariff points accessibility in the context of developing the selected region. From the passenger´s point of view, it is necessary to specially assess the accessibility of lines within transportation, between the selected destinations using passenger air transport. The length of the travel time, the number of necessary transfers and the number of travel opportunities affects the possibilities of transport between place A and B. The connections and lines are thus influenced by many factors. This is the basic point to consider when designing a set of evaluation criteria for assessing the connectivity and in carrying out a case study for a specific region. In this paper, Václav Havel Airport in Prague (Czech Republic) with selected air transport connections were evaluated according to the proposed methodology.

Opis:
The paper deals with the implementation of research concerning the collection routes of a selected company and subsequent streamlining processes in the field of distribution logistics. Specifically, the paper is focused on the optimization of collection routes of textile waste for the customer, i.e., a contractual partner of the company under investigation. The objective of the paper is to analyse step by step the current state of logistics of supplying a specific warehouse, followed by the application of the centre of gravity method for proposing a warehouse relocation. Finally, the individual routes to collection points are optimized. In general, optimization is done for two basic reasons: profit maximization and logistics costs minimization, which ultimately has a positive impact on earnings. The outcome is to determine the optimal routes with respect to costs and traffic while considering complications that may occur in a given transport territory.

Opis:
This paper addresses an application of the specific methods of multi-criteria decision analysis to specify the appropriate supplier of an autonomous train in a certain production–distribution company. This company identifies three potential suppliers dealing with the development and purchase of autonomous train systems. In terms of the multi-criteria decision analysis, the WSA method, the Scoring method and the TOPSIS method were used to define a suitable compromise solution. To apply each method, individual suppliers were sorted depending on the appropriateness for the examined company based on relevance with all the identified criteria and their weights. The evaluation criteria include procurement cost, time of the whole autonomous train system project implementation, references from plants where such a technology has already been introduced, service department availability and battery charge time. Thereafter, the outcomes obtained using individual methods were compared to each other and the compromise supplier of the autonomous train system to be implemented in the selected company was determined.

Opis:
The health style of the population has deteriorated in the last 10 years, given the possibilities offered by an increasingly advanced civilization. The paper attempts to find the answer to the question whether the development of motorization has an effect on civilization diseases. To this end, the paper began with an analysis of the registered numer of means of transport in Poland and an analysis of the number of cases of malignant and respiratory tract cancers. Then, the focus was on the analysis of exhaust toxicity, discussing its definition and determining the limit values for exhaust toxicity occurring in the means of transport. In the next section, the paper was carried out on the toxicity of exhaust gases of lorries and passenger cars affecting human health. Finally, the paper ends by summarizing the results and drawing the appropriate conclusions.

Opis:
Increasing transport volumes on Europe's inland waterways is a major reason for improving the quality and reliability of internationally important waterways. Continued navigation restrictions due to restricted draft (draught) led to the search for new design solutions. Such solutions enable navigation even under critical navigation conditions. Restricted draft is one of the most important limitations that hinder navigation, especially in the summer. The main objective of the construction of an inland vessel is to obtain a shape that will achieve optimum performance with as little resistance as possible. A shape that will be able to navigate at a limited depth. Presently, there is no clearly defined methodology as a procedure for optimising the hull. When solving theoretical problems of shipbuilding character and ship calculations, it is necessary to consider the basic theory of the ship with special regard to the latest methodological procedures of related scientific disciplines. This paper presents a methodology that considers all the basic aspects of optimisation tasks in ship design and construction.

Opis:
Suggesting the proper location for logistics facility can be considered as a decision making problem, wherein the final solution/decision is affected by multiple external or even internal circumstances. In order to address the decision making issues, various multi-criteria decision making (MCDM) techniques may be implemented; and hence, they can be applied even when making a decision about an adequate logistics service center (LSC) placement in an examined territory (i.e., national logistics network of the selected territory), which is an aim of this manuscript. Following the statements above, as for the individual instruments of MCDM to be implemented in terms of the crucial objective of this research, the definite decision making process will be carried out by applying the Analytic Hierarchy Process (AHP) followed by the Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS), on the basis of criteria weights defined by the Saaty pairwise comparison method. The methods used appear to be ideal instruments towards decision making on the most suit-able location which is represented by the region in our case. Subsequently, these will be ordered from the most preferred to least one by using a preference ranking. As a result of the application of AHP and TOPSIS approaches, based on the conducted calculations in regard to decision making on identifying the proper LSC location out of eight selected regions, one specific region will be defined as the most suitable (so-called compromise) scenario. Individual tools allow for reducing the number of assigned criteria that are taken into account in searching process for individual solutions. In order to objectify the entire decision making procedure, ten topic-involved experts having practical experience with a subject of logistics object allocation will be asked to participate in the process. Preferences differ from one decision maker (expert) to another; hence, the outcome depends on who is making decisions and what their goals and preferences are.
