Very few techniques exist for reliability evaluation of communication systems where links as well nodes have certain probability failure. This correspondence describes a technique by which the expression such system can be conveniently derived. It is also shown that using concept this correspondence, it possible to extend all existing reliability-evaluation algorithms with little effort.
A simple and efficient technique for solving integer-programming problems that normally arise in system-reliability design is introduced. It quickly solves even a very large system problem. consists of systematic search near the boundary constraints involves functional evaluations only. can handle any type which decision variables are restricted to integer values. Several illustrative examples given substantiate these assertions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML"...
An algorithm is developed to obtain a simplified reliability expression for general network. All the success paths of network are determined; then they modified be mutually disjoint. The follows directly from disjoint paths. easy and computationally economical. involves fewer terms arithmetic operations than any existing methods. This an advantage, considering size system engineer normally handles frequency with which used studies.

A flow graph approach for reliability analysis is applied to redundancy with elements in the simple series-parallel networks and more general case non-series-parallel combinations. The of open or short failures analyzed graphs. Typical examples are shown.
An algorithm for the heuristic solution of redundancy optimization problems is presented. There may be any number constraints which need not linear. For selecting stage where to added, a criterion introduced takes into account relative increment in reliability versus decrement slacks. The simple and requires minimum computation.
The redundancy optimization problem is formulated as an integer programming of zero-one type variables. solution obtained making use algorithm due to Lawler and Bell. Objective function constraints can be any arbitrary functions. Three different variations the are considered. formulation easy convenient on a digital computer. size that solved not restricted by number constraints.
This paper provides a simple algorithm for the solution of redundancy optimization problem in presence multiple linear constraints. Basicaily, to an r-constraint is obtained successively from r-unconstrained problems. At each step, active constraint picked out, then maximum gradient concept used find closer point. The approach requires minimum effort and time solution.
Summary Dynamic programming formulation for obtaining the optimum number of redundancies at each stage in a system is explained detail. It also emphasized and illustrated by examples, that 'summation' form functional equations, as suggested paper, provide faster solution to an otherwise computationally voluminous method.
Reliability evaluation of a large and complex system is quite an involved time-consuming process its state-of-art far from being called as satisfactory. This mainly due to the fact that unionizing path sets results in number terms reliability expression. Thereafter, computing numerical value expression task not free build up round-off errors. The entire also restricts use low-end PC for such systems. In this paper, we propose efficient methodology evaluate systems based on minimal sets;...
This paper presents a method for optimal load curtailment in power system taking into account of generator control effects and voltage frequency characteristics loads.

It shown speed can be increased approximating matrix using complementary Davidon-Fletcher-Powell update. illustrated on alO-bus II=...
The method of Lee and the simple application graph theory seem to give different answers for flow networks. Lee's is correct. whereby can be extended correct results explained.
In this paper, we propose a hybrid method to evaluate reliability of large and complex networks that incorporates the best features earlier techniques such as KDH88 CAREL. The present combines CAREL’s COMpare REDuce operators along with eliminates use other two CAREL, thus resulting in an extensive reduction number exclusive mutually disjoint terms. procedure not only saves CPU time by appreciable amount but also can be run even on low‐end PC. To demonstrate advantage handling system...
A nuclear power plant generally consists of subsystems that may employ any the partial, standby and active redundancies. The design such a mixed redundancy system under some techno-economic constraints, is quite important in order to achieve specific objectives. Often objective maximize reliability given constraints (mainly cost constraint). In present paper an algorithm described which makes solution this mathematically difficult problem possible. has been found powerful efficient solve...
