<p style='text-indent:20px;'>Redundancy allocation problem (RAP) is a common technique for increasing the reliability of systems. In this paper, new model RAP introduced that takes into account warm standby and mixed strategy, dynamics, type strategy in redundancy problems. A recursive formula first obtained function dynamic strategies leverages success mode analysis works any arbitrary f...

in this paper, the energy efficient resource allocation in noma-based heterogeneous cellular network(hcn) systems is investigated. since energy consumption and its limitations is one of the important challenges in fifth generation of cellular networks (5g), we propose a resource allocation problem which allocates power and subcarriers to multiple users to achieve the best system energy efficien...

Concurrent error detection (CED) based on time redundancy entails performing the normal computation and the re-computation at different times and then comparing their results. Time redundancy implemented can only detect transient faults. We present two algorithm-level time-redundancy-based CED schemes that exploit register transfer level (RTL) implementation diversity to detect transient and pe...

facility location-allocation models are used in a widespread variety of applications to determine the number of required facility along with the relevant allocation process. in this paper, a new mathematical model for the capacitated multi-facility location-allocation problem with probabilistic customer's locations and fuzzy customer’s demands under the hurwicz criterion is proposed. ...
