Path planning and obstacle avoidance algorithms are requested for robots working in more and more complicated environments. Standard methods usually reduce these tasks to the search of a path composed from lines and circles or the planning is executed only with respect to a local neighborhood of the robot. Sophisticated techniques allow to find more natural trajectories for mobile robots, but a...

Information and communication technology (ICT) enable information to be accessed processed through all kinds of visual, audio, printed written tools. This study aimed evaluate the ICT development G7 countries by using Multi Criteria Decision Making (MCDM) methods. Accordingly, Entropy method was used specify criteria weights, Proximity Indexed Value (PIV), Range (ROV), COmplex PRoportional ASse...

Selecting the most suitable alternative under uncertainty is considered as a critical decision-making problem that affects the success of organizations. In the selection process, there are a number of assessment criteria, considered by a group of decision makers, which often could be established in a multi-level hierarchy structure. The aim of this paper is to introduce a new hierarchical multi...

When we apply safety analysis techniques on a new design, our primary objective is to anticipate potential scenarios of failure in the system under examination. If we assume that the system has a complex hierarchical structure, this task can be interpreted as one of identifying how failures originate at the low-levels of the design and how combinations or sequences of such low-level failures pr...
