A new approach to rank the decision making units in presence of infeasibility in intuitionistic fuzzy environment

Data envelopment analysis (DEA) is a linear programming based methodology to determine the relative performance efficiencies of homogeneous decision making units (DMUs). In real world applications, some input and output datas do not possess crisp/fuzzy essence but they possess intuitionistic fuzzy (IF) essence. So, in this study, we develop an IF BCC (IFBCC) and an IF super efficiency BCC (IFSE...

The Infeasibility of Experimental Quanti cation of Life-Critical Software Reliability

This paper a rms that quanti cation of life-critical software reliability is infeasible using statistical methods whether applied to standard software or faulttolerant software. The key assumption of software fault tolerance|separately programmed versions fail independently|is shown to be problematic. This assumption cannot be justi ed by experimentation in the ultrareliability region and subje...

Systematic integrated approach to quantifying preventive diagnostics in a “smart” transport system

One of the main tasks facing all European countries for the next few years is the creation of the most dynamically organized transport sector. The constant passenger and freight traffic lead to congestions and pollutions at the transport highways, having negative impact on a person. Thus, introduction of new technologies, addressing the interrelated problems of optimizing transport flows and im...

Proposing an Efficient Software-Based Method for Enhancing the Reliability of Critical Application Robot

Robots play such remarkable roles in humans’ modern lives that performing many tasks without them isimpossible. Using robotic systems is gradually increasing the tasks allocated to them and they are becomingmore complex and critical. Software reliability is one of the most significant requirements of robots. Forenhancing reliability, systems should be inherently designed to be tolerable of soft...
