Spacecraft Expected Cost Analysis with k - out - of - n : G Subsystems
نویسنده
چکیده
bin(k-1 ;n,p) = L n p xqn-x, the cumulative binomial function. k-1 ( ) x=o x C=the total of the cost of the subsystem itself plus the expected cost due to subsystem failure c1 = loss due to failure of the subsystem c3 =cost of a one module subsystem capable of full output c4 =cost of a module in a k-out-of-n:G (good) subsystem when k is fixed g(k) = the function relating cost of the subsystem to the number of modules in subsystem k = minimum number of good modules for the subsystem to be good n = number of modules in the subsystem

RELIABILITY MEASURES AND SENSITIVITY ANALYSIS OF A COMPLEX MATRIX SYSTEM INCLUDING POWER FAILURE
This paper investigates the reliability characteristics of a complex system having nine subsystems arranged in the form of 3x3 matrix in which each row contains three subsystems. The configuration of the row is of the type 2-out-of-3: F. Each subsystem has n units connected in series. The system fails if any one row containing three subsystems fails. The considered system analyzed incorporating...
متن کاملAvailability Optimization of a Series Repairable System with Multiple k-out-of-n Subsystems
An availability model is developed to optimize the availability of a series repairable system with multiple k-out-of-n subsystems in this paper. There are two types of decision variables that determine the system designer’s decision to allocate the number of repairmen and to allocate the number of redundant components in each subsystem in the presence of weight, volume and cost constraint...

This paper deals with the transient analysis of K-out-of-N: G system consisting of Noperatingmachines. To improve system reliability, Y cold standby and S warm standbys spares areprovided to replace the failed machines. The machines are assumed to fail in multiple modes. At leastK-out-of-N machines for smooth functioning of the system. Reliability and mean time to failure areestablished in term...
متن کاملAvailability of k-out-of-n: F Secondary Subsystem with General Repair Time Distribution
In this paper we study the steady state availability of main k-out-of-n: F and secondary subsystems having general repair time distribution. When more than k units of main subsystem fail, then the main subsystem shuts off the secondary subsystem. The life time distributions of the main units and that of secondary subsystem are exponentially distributed. A repair facility having single repairman...
متن کاملN-Policy for M/G/1 Machine Repair Model with Mixed Standby Components, Degraded Failure and Bernoulli Feedback
In this paper, we study N-policy for a finite population Bernoulli feedback queueing model for machine repair problem with degraded failure. The running times of the machines between breakdowns have an exponential distribution. The repair times of the machines are independent and identically distributed random variables. If at any time a machine fails, it is sent to the repairman for repairing,...
