Optimization of multi-state elements replacement policy for multi-state systems
2010 Proceedings - Annual Reliability and Maintainability Symposium (RAMS), 2010In this paper, we generalize a multi-state element (MSE) replacement optimization problem to multi-state systems (MSS), in which a global optimal MSE replacement policy is obtained to achieve better outcome than local optimal MSE replacement strategy which does not consider the system performance rate dependency.

Ordered multi-state system signature and its dynamic version in evaluating used multi-state systems
Probability in the Engineering and Informational Sciences, 2022Signature theory plays an important part in the field of reliability. In this paper, the ordered multi-state system signature and its related properties are discussed based on a life-test of independent and non-identical coherent or mixed systems with independent and identical binary-state components.

Automated test generation for multi-state systems
Proceedings of the 15th annual conference companion on Genetic and evolutionary computation, 2013This paper describes a genetic algorithm based on mutation testing to generate test cases for classes with multiple states. The fitness function is based on the coverability and the killability of the individuals. The paper includes a small empirical section that shows evidences of the ability of the algorithm to generate good test cases.

The number of Boltzmann factors in the partition function increases with increasing energy states. The higher energy states might have small Boltzmann factors but are included for completeness. This leads to infinite sums that can sometimes be reduced to a simple partition function to calculate average energy, entropy, and free energy.

Dynamic reliability indices for multi-state system
33rd International Symposium on Multiple-Valued Logic, 2003. Proceedings., 2003The Multi-State System reliability is investigated in this paper. The new class of Reliability Indices is obtained. We have called these indices as Dynamic Reliability Indices. These indices estimate influence upon the Multi-State System reliability by the capacity levels of a system component.

Reliability assessment for fuzzy multi-state systems
International Journal of Systems Science, 2010Fuzzy multi-state system (FMSS) is defined as a multi-state system (MSS) consisting of multi-state elements (MSE) whose performance rates and transition intensities are presented as fuzzy values. Due to the lack, inaccuracy or fluctuation of data, it is oftentimes impossible to evaluate the performance rates and transition intensities of MSE with ...

Multi-state systems with multi-fault coverage
Reliability Engineering & System Safety, 2008Abstract The paper introduces a new model of fault level coverage for multi-state systems in which the effectiveness of recovery mechanisms depends on the coexistence of multiple faults in related elements. Examples of this effect can be found in computing systems, electrical power distribution networks, pipelines carrying dangerous materials, etc ...

The multi-state information system
Proceedings of the 1974 annual conference on XX - ACM '74, 1974The Multi-State Information System (MSIS), a patient oriented, clinical and administrative system designed for use in Psychiatric hospitals and Community Mental Health Centers, is currently in use in twelve states and several countries. The need to protect the confidentiality of the highly sensitive data stored by the users of this system and at the ...

Reliability analysis of multi-state complex system with multi-state weighted subsystems
International Journal of Quality & Reliability Management, 2019Purpose 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.

On Semi-Markov Modelling and Inference for Multi-state Systems
2016 Second International Symposium on Stochastic Models in Reliability Engineering, Life Science and Operations Management (SMRLO), 2016In this work we focus on multi state systems that we model by means of semi-Markov processes. The sojourn times are seen to be independent not identically distributed random variables and assumed to belong to a general class of distributions that includes several popular reliability distributions like the exponential, Weibull, and Pareto.
