Abstract
Purpose
The purpose of this paper is to evaluate the reliability indices such as reliability, mean time to failure and sensitivity analysis.
Design/methodology/approach
A non-repairable multi-state complex system with two subsystems, namely, S1 and S2, is studied. The subsystems S1 and S2 are multi-state weighted r-out-of-n: G and s-out-of-m: G systems, respectively. Every component of the sub-system S1 consists of linear (f, l, k): G system, and the sub-system S2 consists of circular (f, l, k): G system. The subsystems are connected in series arrangement and components of these subsystems are arranged in parallel.
Findings
Markov stochastic process has been applied to obtain probability of components of the subsystems and various results discuss such as reliability, mean time to failure and sensitivity analysis with the help of the universal generating function.
Originality/value
In this work, reliability measures of the purpose system can be enhanced under the high profit.

Abstract
Purpose
To find the reliability characteristics of repairable weighted (u, v)- out-of-(x, y) system using the interval valued universal generating function (IUGF).
Design/methodology/approach
In this paper (u, v)-out-of-(x, y) system is an extension of the k-out-of-n system. Here, the interval valued universal generating function (UGF) is present and the corresponding operators are defined.
Findings
The present paper proposes a interval valued universal generating function (IUGF) to compute the reliability indices of the considered system. The current study investigates the reliability and sensitivity of the proposed system with respect to system parameters by applying Markov process with the help of the interval valued UGF approach.
Originality/value
In this work, the considered system, i.e. repairable weighted (u, v)-of-the- (x, y) is the extension of k-out-of-n system for the assessment of reliability characteristics using the interval valued UGF.
