Assurance of the supervised conditions in all processes affects directly both products and users safety and environmental influence. ISO 9001 and ISO 14001 standards in Operation point require from organisations to implement and control the planned processes by establishing processes’ criteria, assuring the supervised conditions and verifying processes’ conformity. Moreover, in Planning section it is required to plan the processes with the consideration of quality and environmental risk. Therefore research on the practical solutions of operational planning and control in the production processes are of the crucial meaning, especially from the perspective of the integrated fulfilment of the requirements. That is why the value of the paper is being constituted by the authorial methodology of identification of the key-operational criteria, including integrated risk assessment, using the computer support and being a starting point for assurance of the supervised conditions in the key-processes of high risk. The worked out methodology has been implemented in the processes of performance and completing the stirrups, which quality is of the huge influence on the work safety of the mine roadway supports in the mine workings. The aim of the analysis was to identify the operational parameters in the stirrups technological process, to estimate their meaning and to point at the key operational criteria from the point of fulfilling the quality and environmental requirements. Practical implication of the proposed methodology can be applied in case of any organisation which wants to improve the realised processes ensuring the computer supported supervised conditions.
The paper investigates the sensitivity of safe ship control to inaccurate data from the ARPA anti-collision radar system and to changes in the process control parameters. The system structure of safe ship control in collision situations and computer support programmes exploring information from the ARPA anti-collision radar are presented. Sensitivity characteristics of the multistage positional non-cooperative and cooperative game and kinematics optimization control algorithms are determined through examples of navigational situations with restricted visibility at sea.
The article concerns the use of computer support systems for technical support in the difficult conditions. The term difficult conditions should be understood as such conditions, in which an operation is carried out in a specific location, impeding or preventing the use of the computer. In such cases, computers integrated with operators’ working clothes (wearable computers) should be used, with which the communication takes place using voice. This article shows the attempt to resolve the problem of voice communications in a portable system to handle aircraft M-28.
Optimization of Workplace Design for People with Alternative Abilities
An employer who wants to employ a person with alternative disturbances faces a difficult problem of selecting a workstation and tasks suitable to a given person's disease since even the same case of disease does not guarantee identical organizational solutions of a workstation. However the more complex the movement disfunction, the more difficult the task is. At the same time it is important that work results of a workstation allow achieving complex productivity. The article presents an attempt at elaborating a method aided by a computer system which allows introducing changes or modifications of workstation space, place equipment and facilities or installing additional elements enabling effective and productive work performance by a person with precisely defined abilities. Presented results of piloting researches have proven that the elaborated method of aiding decisions while adapting workstations to needs and abilities of people with movement disfunction will bring social and economic benefits.
This article is an proposition to the use of contemporary CAD (Computer Aided Design) solutions for industrial infrastructure design, and to showing the many benefits of their practical use, avoiding many mistakes during the investment process, thereby increasing the quality of the creating products while reducing the costs associated with their production. The paper proposes a method of inventory of the current state and methods of spatial layout analysis of planned investment using smart databases to configure the individual manufacture slots. Presented is method of material flow analysis in the virtual model of the production line, tools for line analysis with particular focus on collision identification, job scheduling and parametric analysis of the planned installations.
This article is a proposition to use modern CAD (Computer Aided Design) solutions to design industrial infrastructure, and show many benefits of their practical use, avoiding numerously mistakes while the investment process, at the same time increasing the quality of created products during reducing the costs associated with their production. The paper proposes a method of stocktaking of the current state and methods of spatial layout analysis of planned investment using smart databases to configure the individual manufacture slots. The method of material flow analysis in the virtual model of the production line was presented, tools for the analysis of the production line were indicated, especially focused on collision identification, work schedule creation and parametric analysis of designed installations.
This article describes methods used in estimating skeletal age based both on the evaluation of skeletal maturation of the palm and the wrist (Greulich and Pyle’s atlas method) and the Cervical Vertebral Maturation method (CVM). The method of evaluating the skeletal age based on the measurement of cervical vertebrae with equations introduced by A. Machorowska-Pieniążek is also mentioned. The article shows results obtained by computer analysis of the age of cervical vertebrae compared to the results gained from the implemented equations provided by A. Machorowska-Pieniążek and the results obtained from the atlas method.
The research within the development of digital factory concept concerns also the assembly process as an important part of the production. This paper presents an assembly operations sequence model as a part of design and planning method for the assembly process. This model enables to obtain a precise graph presentation as a tool for computer support.
The paper deals with computer support of safety analysis of railway control system corresponding to each stage of its life cycle, especially design, testing and maintenance. It is related to the reliability estimation of actually designed, manufactured or exploited from several years railway control systems. But is possible to analyze with computer support the occurrence of critical situations using FTA method, estimation of probability connected with such situations and verification of obtained results using simulation methods. The paper is final report of research works realized in Electronics&Diagnostics Department in Faculty of Transport and Electrical Engineering UTH in Radom.
This article is devoted to works on using natural user interfaces (NUI) in computer support systems of aircraft service. The concept of such interfaces involves the usage in human-machine communication the same measures as in the communication between people, that is sound or gesture. In the case of gesture communication, it is indispensable to adopt methods related to computer vision algorithms. One of them is a three-dimensional reconstruction of objects based on processing techniques of a pair of two-dimensional images. The above method and the results of its application were presented to obtain a three-dimensional cloud of points describing the hand shape. The obtained software will constitute an element of gesture classifier based on the analysis of the spatial location of the acquired points of the cloud.
