If organizations want to be successful, they must quickly adapt to changing conditions in a competitive environment, must be flexible and must quickly resolve situations and problems occurring in organization. We use different tools and methods to solve these problems. One of these methods is Eight Disciplines Problem Solving (8D). The 8D method is a structured problem solving process. This method helps to correctly and timely solve problems. It is used when the cause of problem is unknown or when the solution to problem is beyond the capabilities of a single worker. This method is also used to improve products and processes
This paper deals with the issue of using ecological oils in the sliding pair of hydraulic and transmission systems working in the area of agriculture. The sliding pair included a B 60 bearing and a journal with contact surface made of 14 220 steel. The experimental tests were carried out with two oils: the Fuchs Plantohyd 46 S ecological oil and PP 80 reference oil (producer: Slovnaft) which is a commonly used lubricant in given conditions. The results of the experiments were statistically processed and based on them, friction coefficient and temperature, both depending on the test duration, was evaluated. Consequently, the weight loss and roughness change of both tribological elements were statistically processed.
This work is focused on determining the capability of production equipment in Volkswagen Slovakia, a.s. during the moulding of a car door. There were taken 150 samples from the moulding process that followed each other. Values were recorded on a Wenzel RAplus 1625 measuring machine. Subsequently, process stability was verified. It showed that measured values had a stable average value, and the process did not show irregularities in the diagrams of the X card and s card. After verification of stability, the values of C m and C mk were calculated, which exceeded the minimum requirement of 1.66 and 1.67, and the requirements for the capability of production equipment have thereby been met.
Risk is virtually present everywhere around us. Nowadays, there is an increasing focus on safety at work; therefore, the organizations that want to be successful in the market try to eliminate risk factors to a minimum to avoid or prevent the health hazard of employees, damages to property or the environment. The work is focused on the risk assessment of a selected device, which is the most risky workplace according to the organization where the research was conducted. In the practical part, we became familiar with the equipment for welding and a thorough analysis of the current state of safety by a complex method was done. Consequently, corrective actions to reduce risk to an acceptable level were proposed. After that, we reassessed the risks of complex method, and the point method was used to verify the effectiveness of proposed remedial measures.
Reliability and quality are strongly linked between each other although people are often confused and consider these to be the same. Quality is defined as the ability to satisfy requirements that customers had determined or expected. If an organization manages to fulfill preconditions and requirements, it has a potential that customers will continue to use its products while buying new ones. Reliability can be named as an indicator expressing the probability that a product will perform the function it was made for and for a period specified in given operating conditions. In this work, we have focused on monitoring the specific parameters in two types of grain harvesters in operating conditions. Keywords: grain harvester, quality, organization, reliability Abstrakt Spoľahlivosť a kvalita majú medzi sebou silnú väzbu. Ľudia sa často mýlia a považujú ich za to isté. Kvalitu definujeme ako schopnosť uspokojiť požiadavky, ktoré si určili zákazníci alebo ich očakávali. Ak sa podarí predpoklady a požiadavky naplniť, organizácia má potenciál, že zákazník bude pokračovať v používaní jej výrobkov a zároveň kúpe nových. Spoľahlivosť môžeme nazvať ako ukazovateľ vyjadrujúci pravdepodobnosť, že daný výrobok bude vykonávať požadovanú funkciu, pre ktorú bol vyhotovený, po dobu stanovenú v daných prevádzkových podmienkach. V práci sme sa zaoberali sledovaním konkrétnych parametrov u dvoch typov obilných kombajnov v prevádzkových podmienkach.
