Moreover, it studies the effects of early robust design decisions with a focus on SuhвЂ™s Axiomatic Design axioms on later parameter and tolerance optimization. Motivated by this, this paper bridges the gap between these two different views by contrasting the used terminology and methods. This is mainly due to the break between the primarily qualitative approaches for the concept stage and the quantitative parameter and tolerance design activities in subsequent stages. Despite the large number of methods and tools available for designers and tolerance engineers, there are hardly any consistent approaches that are applicable throughout all development stages.

The development of complex products with high quality in dynamic markets requires appropriate robust design and tolerancing workflows supporting the entire product development process. This study can be used for the methodology and design of preventive measures to ensure safe inland navigation. The analysis confirmed the presence of recurring hazards, resulting mainly from human behaviour. Two methods were applied to fulfil the aim-a cause and effect diagram, used for hazard identification, and a risk matrix, used for risk assessment. This paper provides a comprehensive study of the hazards (causal factors) and resulting risks in inland waterway transport. For this purpose, data about real accidents on the Danube River were collected and analysed in this study. At present, comprehensive research on inland navigation accidents including their causes and consequences is lacking. Accidents in inland waterways are a regular phenomenon throughout the year, causing deaths, injuries, and monetary loss, and endangering the environment. Ways to build the awareness of household users through a modern quality management tool calledД®ven though inland navigation represents the safest transport mode, consequences of accidents are significantly higher, because of the larger quantities of cargo transported, compared with the conventional means of transport. Have knowledge of energy and the factors that influence the increase in its consumption but are notДЄware of why energy should be saved and what it means for the environment. The results of the study clearly show that the respondents The C-Pearson coefficient canД«e calculated using the Chi square value. The researchers calculated theД¬hi-square test, which allows them to determine PearsonвЂ™s C coefficient. Of increasing energy consumption in households has been built. To analyze the causes of the increase in energy consumption in households. Quality management tool was used-the Ishikawa diagram. Same time, in order to consider why energy consumption in households is increasing, a traditional Additionally, it was given a qualitative analysis. A household energy awareness literature review was conducted. PeopleвЂ™s lifestyles around the world, energy demand and consumption have risen quickly in recentДecades. We opted for a new model of Ishikawa diagram, resulting from the composition of three fish skeletons corresponding to the main categories of parts accuracy.Д«ecause of disruptive changes in energy businesses and services, as well as changes in For each of the three categories of causes there were distributed potential secondary causes on groups of M (man, methods, machines, materials, environment/ medio ambiente-sp.). We took into account the main components of parts precision in the machine construction field. The paper shows the potential causes of the studied problem, which were firstly grouped in three categories, as follows: causes that lead to errors in assessing the dimensional accuracy, causes that determine errors in the evaluation of shape and position abnormalities and causes for errors in roughness evaluation. The most known Ishikawa models are 4M, 5M, 6M, the initials being in order: materials, methods, man, machines, mother nature, measurement. The studied problem was'errors in the evaluation of partsprecision' and this constitutes the head of the Ishikawa diagram skeleton.All the possible, main and secondary causes that could generate the studied problem were identified. The paper presents the results of a study concerning the use of the Ishikawa diagram in analyzing the causes that determine errors in the evaluation of theparts precision in the machine construction field.
