The study of the formation process of the operation quality of a transport firm is the most topical, since this process significantly determines the dynamics of its evolution. The paper presents the concept of the product and service quality, describes the difference between the service and the product, as well as a step-by-step scheme of quality development. The history of quality management development is also discussed on the example of three leading regions of the world: USA, Japan and Western Europe.
Methods for assessing the quality of products and services have been established, which are somewhat different from each other and are of great importance for assessing the activities of a transport enterprise.

The paper presents the results of quality evaluation of weldments produced by a mutual combination of different steel grades. Weld joints were made using GMAW technology (method -135 ISO 4063). The type of welding parameters used for the quality of welded joints was monitored. The quality of welded joints was assessed using non-destructive tests. In non-destructive tests, the Visual test according to EN ISO 17637, the Penetration test with colour indication according to EN ISO 22476-12 was used to identify surface defects. The presence of internal errors was assessed by a radiation test according to EN ISO 17636-1. Within the destructive tests, the quality of the welds was assessed by a tensile test according to EN ISO 6892-1, by the test of brittleness of welds according to EN ISO 5173, the course of hardness according to EN ISO 6507-1 was determined on transverse cuts. The bending impact test according to EN ISO 9016 will determine the toughness of the weld metal and heat-affected areas. Metallographic analysis of welds according to EN ISO 17639 was performed on transverse metallographic sections using light microscopy. Based on the performed experiments, recommendations were set, or proposed changes in the welding procedures of the given steel grades.

Quality is a process of continuous improvement or improvement of the processes creating the product. Our ability to manage quality characteristics has a significant impact on the depth of our knowledge of the process used for the desired transformation. The application of knowledge in process management depends on the dominant factor for management: human or machine. Each requires an appropriate form of transfer of knowledge. Depending on the type of “human-machine system”, it is possible to use various mathematical and logical tools to formalize the information. This article attempts to classify the types of mathematical and logical tools applicable to process management, depending on the “human-machine system” use.

Nowadays ensuring high-quality software product requires a lot of testing efforts. Automated tests in the 21st century are a must. Whether it’s code peer-review, unit, integration, system or exploratory user testing – it all has to be done with given insurance and expertise! Therefore, we look to automate our testing where is conceivable. Most applications today have the equivalent of Web and Mobile versions for the same functionality, but different platforms of action in order to facilitate the users. Therefore, parallel testing of both subtypes is required to provide smooth maintenance and rapidity. Running as many builds as possible, including tests to ensure quality is essential when comes up to reliable software product and agile development. With the implementation of Continuous Integration and Continuous Delivery tools, we guarantee a better way to deploy automated tests across multiple instances and execute them against those environments. BrowserStack is one common cloud solution to these requirements. It is a very powerful tool, which can be attached to our development process. This article explores detailed approach on the automation of cross-browser, device and compatibility testing in BrowserStack platform, using a custom extended automation framework to provide direct configuration output to this environment and give ease in the future Web and Mobile development.

Over the last two decades, software testing has expanded in terms of both the tools used to perform different types of activities and mind-set of the people using those tools. Automated testing involves use of strategies and instruments that perform testing activities of a software product and where the interference of a person is mainly related to the research of the results of these activities. Automated testing processes are popular because of the benefits that make them an indispensable tool in everyday work for testing activities. The main advantage of automation is the abstraction of rehearsal processes within the tested system. In this way, a complete separation of the human operations from the system is achieved, as only the functionality that needs to be programmed. This article presents the development of an automation-based testing framework “Stassy” – System Stable Testing, which supports and helps to implement easily new tests related to Web platforms. The implementation includes the following structure: Object repository, Functional libraries, Global variables and Constants, Data Provider, Test scripts, Configuration files, Recovery scenarios, Loggers, Clean-up scripts and Reporting mechanism. With the advantages of Page Object Pattern and using of the following technologies: Java programming language, JUnit and TestNG extended libraries. The created scripts represent automated acceptance, functional and non-functional tests in which Page Object is used to separate those tests into individual fragments and subsequently call them in a different order according to the automation requirements and business logic. We will track the overall preparation and creation of “Stassy” automated framework and explain the benefits of such approach.

The most important element for achieving a sustainable development of aviation is human resources and the provision of opportunities for acquiring the necessary knowledge, skills and competencies. In this sense, aeronautical training schools are becoming more and more crucial for increasing productivity and competitiveness, as well as helping people realize their full potential and achieve their personal goals.

Quality has a fundamental influence to the services in passenger transport. The main objective of transport is to satisfy customers’ (passengers’) requirements on the qualitative, flexible, fast and safe carriage of people and goods. Organisers of transport (public authority), providers of transport services and their customers have a different view on the perception of quality. This fact is influenced by unsystematic assessment to the quality measurement as well as by ignorance of the interaction of the transportation the peoples with the transport system. A basic element of transport service is the movement of the rolling stock with the passenger or goods from the start to end destination. In this point of the technological process of transport, the main bearer of the quality of transport services are the vehicles and the transport infrastructure. From the perspective of the vehicle, its operation-technical and utility properties are very important. From the perspective of transport infrastructure, the operating ratios and conditions are important. Due to the content of the quality concept it is not possible to focus only on the interaction of carriage and transport infrastructure. The paper is focussed on the quality evaluation of performance in regional passenger rail transport in relation to other modes of public transport. Hereby it is necessary to know the perception of quality services as well its value for the client (passenger). Consequently it is needed to set a permanent process of quality evaluation of the provided transport services. The paper is based on the premise that the customer interests present the public ordering body (authority) of the public transportation services.

Reveals the scientific and methodological principles of definition agro-technical period for harvesting of walnuts depending on intensity fall fruit and the quality nut kernel.

Correlations between some basic quality parameters of a drug product, which are very important for the pharmaceutical manufacture of solid dosage forms are studied, on the base of experimental data from 135 batches. Factor analysis, control charts and histograms are implemented for the quality parameters – strength of tablet, assay of the active substance, acid resistance, disintegration), water content, drug dissolution after 150 minutes and drug dissolution after 165 minutes.. The parameter drug dissolution after 120 minutes is dropped from the analysis, because it was observed to have a zero value for all measurements. The main aim of this article is to search for a possible underlying structure in the variables with exploratory factor analysis, to monitor whether the quality parameters’ variation is consistent and the empirical distributions of the most important quality parameters using control charts and histograms.

The efficiency of the machines depends on the completeness of the scope of the indicators and the factors with which they are linked.

In choosing the best solutions, it is necessary to evaluate the system metrics, and the optimal option machine or set of machines to be chosen using optimization criteria.

The indicators for the quality assessment of mechanized works should be divided into common types for all mechanized works and for separate groups of technological processes: soil treatment, sowing and planting, plant care, harvesting of crops.

The system of indicators for the evaluation of agricultural machinery is expressed and evaluated with a large number of properties, indicators and characteristics of quality and reliability.

In general, quality has four groups of properties: feasibility, social, bio-ecological and reliability.

Issues related to security are intertwined in all areas of the life of an organization. Many of them are considered and documented organizational and provided within the respective area/subsystem of the management system of the organization. For example, information security management is detailed and reliably described in the international standards. And this is natural, considering the importance of this type of security and the fact that information technology lie at the core of almost all organizations. In the meantime however, it is necessary to go a long way to reach the ultimate goal of improving security of the organizations by developing integrated management systems for business security. A Security Management System may be considered as that part of the overall management system, based manly of the quality management system, that provides the structure to enable identification of potential threats to an organization and which establishes, implements, operates, monitors, reviews and maintains all appropriate measures to provide assurance of the effective management of the associated security risks.
