The Management and Potential Risk Reductionin the Processing of Rare Earths Elements

Abstract

The rare earth elements (REE) are vital to innovation technologies and society and are important for the industry, especially for high-tech solutions. In the modern world, anumerous applications have been developed using rare earth elements (REE), implying human exposures and raising unclear questions as to REE-associated health effects. Protecting the environment and public health from disadvantageous actions of rare earth elements mining and processing as emerging pollutants is urgently desired to achieve sustainable development. All activities in mining processes like extraction, separation and after recycling of REE elements could create rick to human health and environment. In the paper the role of management in safety aspects during mining and processing of rare earth elements has been highlighted. In the paper, the potential dangerous and damaging effects on the environment and human health have been identified - the potential risk in the processing as well as the possibilities of preventing the occurrence of hazards have been analyzed.

Management The Safety of Exploitation of the Rotation Mechanism in a Self-Propelled Crane

Abstract

The article analyzes of the load capacity of the rotation mechanism of the boom arm sub-assembly for a self-propelled crane. The uneven flexibility of systems supporting structures of the machine was taken into account in the identification of the load. The consideration are illustrated by the example slewing bearing from self-propelled crane. FEM method was used for calculations. The basic problems of construction of numerical model were discussed. Sample calculations of bearing carrying capacity has been done taking into account flexibility of bearings supporting structures, which also allowed to define the internal load distribution in the bearing. On example of the supporting structure of the mobile crane DST 5050 the internal load distribution in the crane bearing at different positions of the crane machine body were defined. During the rotation of the crane body priority angels were indicated. It has been shown that the deformations of the supporting frames are so large that they significantly change the distribution of forces transmitted by the individual bearing rollers.

Matrix Fmea Analysis as a Preventive Method for Quality Design of Hydraulic Components

Abstract

Preventive methods are important group of methods used in the process of design and which are known as quality design methods. The aim of these methods is identification of potential failures and cause-and-effect relationships in consistent and systematic way, and then taking appropriate preventive or corrective actions. The well-known examples of preventive methods also used for modelling and analysis of the criticality (risk) factor are FMEA analysis and FTA analysis. A matrix FMEA analysis method has been presented and discussed in the work. The basic assumptions related to this method were characterized and algorithms for each stages of analysis have been presented. It has been presented practical application of FMEA method on example of selected components of hydraulic system.

Methodology of Trainings in the Scope of Health and Safety

Abstract

The paper stresses the importance of trainings in the scope of Health and Safety, in this H&S management in the functioning H&S systems of contemporary enterprises. The author also presents the principles of training, including H&S training, considering: demonstrativeness, accessibility, awareness of social responsibility, regularity, knowledge durability and binary relations between theory and practice.

The underlying objective of the paper is to present training methods in the scope of Health and Safety. These methods have been aggregated in two groups: explanatory methods and activating methods. Referring to the research conducted within the European programme Leonardo da Vinci „H&S management system in enterprise – introductory module” the author has summarised the criteria for selecting teaching methods with regard to: goals and content of training process, diversification of participants in training groups in the scope of H&S, skills of the trainer and organisational conditions. Moreover, training methods in the scope of H&S have been aggregated, being highly adjusted and reflecting actual professional activities – carried out activities and potential threats that occur at the work post, in the enterprises of training participants. These methods have been characterised considering the following aspects: learning goals, educational resources, organisational conditions and examples of pursued contents.

A Model of Lean Management for Organizational Innovation: Cases in Visegrád and AFTA

Abstract

Originated as a production management philosophy, Lean Manufacturing has successfully transferred and implemented globally. Lean genealogy studies have been conducted, indicating the essential concept now evolves to Lean Management (LM), which is applicable to many branches of production and services management, viz quality and productivity, human resources, knowledge and technology, etc. Innovation has been made to ensure a smooth customization of knowledge and principles, tailored to each organization who is eager to implement this state-of-the-art management system. However, failures are becoming commonplace due to the lack of understanding the core values, and insufficient intensification of compensation for cultural differences. In this paper, cases of implementing LM across the Visegrád group (V4) and the ASEAN Free Trade Area (AFTA) from previous literature are taken into consideration. Factors that differentiate the characteristic of LM are brought to discussion. Therefore, the discovered gap between the two trade blocs urges the in-depth amendment and modification of employed concepts, tools, etc. A model is consequently elaborated, which aims at facilitate the managerial decision-making process regarding knowledge transfer of LM between V4 and AFTA, based on critical factors related to human, technology and culture, i.e. Labor cost, Manual requirement, Awareness, Continuous Improvement culture. This model can be used to predict the change should be made, or the criterion should be fulfilled to transfer the implementation and knowledge of LM effectively.

Multi Criteria Decision Making Model for Logistics Processes in Particular Enterprise

Abstract

Relevant indicators and measurement methods should be assessed in order to contribute to optimize management of an enterprise. Business performance can be measured by various indicators and various business results could be assessed. Analyses of value chains should be focused on specification of so called bottle necks which mention those activities that disable to increase business margin. At the same time, these analyses show the inefficiency caused by oversized of some activities regarding to lower level of assurance or safety and lower performance of other business activities. Importance of multi criteria decision-making methods for evaluation of alternatives doesn´t lie in definite increasing of results objectivity although it should lead to that. Priority of this method lies mainly in simplification of manager´s decision making. It allows managers to arrange alternatives according to extensive file of criteria, it describes particular steps of solution and its logical sequence, this methodology also requires from managers to express their understanding of various criteria importance. All this process of solution is transparent, repeatable and there are evident starting assumptions and also how these assumptions, situations, criteria and incidents affect reached results.

Occupational Hazards Management Using a Grey-Based Decision-Making Approach

Abstract

The objective of this paper is to present and verify the decision-making model which makes it possible to streamline the occupational hazards that tend to occur in the work environment, according to the adopted decision-making criteria. In this way, it will be possible to reduce inconsistencies of decision-makers deciding to focus their preventive measures upon the most important hazards, in the situation when the same assessments for hazards are obtained using classical matrix techniques. Within this model, a grey approach was proposed, which makes it possible for experts to use linguistic variables in such assessments. The following three risk assessment parameters were used as the criteria: probability of occurrence of hazards, level of their consequences, and a possibility to avoid them. The model was verified in a furniture manufacturing company on the basis of 17 key hazards assessment, which had been carried out by: an executive officer, a direct supervision employee, a work health and safety officer, and an expert coming from outside the company. This paper remedies some shortcomings in using the grey theory in occupational risk management, and constitutes an original application of this concept in the work safety area.
