recommendations! Published in 2019 at "Journal of the Brazilian Society of Mechanical Sciences and Engineering"

DOI: 10.1007/s40430-019-1792-x

Abstract: This paper presents a new algorithm belonging to the class of swarm intelligence methods, called the adaptive simplified PSO (ASPSO)-based algorithm, for solving reliability–redundancy allocation problems. In this constrained nonlinear mixed-integer problem, both the number… read more here.

DOI: 10.1016/j.energy.2019.05.043

Abstract: Abstract As most of the energy production and transformation processes are safety-critical, it is vital to develop tools that support the analysis and minimisation of their reliability-related risks. The resultant optimisation problem should reflect the… read more here.

DOI: 10.1017/s0269964818000359

Abstract: This paper studies the allocation of active redundancies to coherent systems on the context that the base and redundancy components have mutual independent lifetimes. For systems with two symmetric components and systems with one component's… read more here.

DOI: 10.1080/00949655.2021.1879080

Abstract: The reliability-redundancy allocation problem (RRAP) is usually formulated based on two main assumptions, (1) using homogeneous components, and (2) having a predetermined redundancy strategy for each subsystem. In this article, both these restrictive assumptions are… read more here.

DOI: 10.1109/access.2023.3248800

Abstract: Multiobjective reliability-redundancy allocation problem (MORRAP) needs to maximize system reliability and minimize cost, weight, and volume with underlining constraints. In the systems’ design and analysis phase, uncertainties can occur from various sources, such as manufacturing… read more here.

DOI: 10.1109/tase.2022.3148459

Abstract: Uncertainty is a practical issue in system design optimization because some characteristics of components, such as reliability and cost, cannot be determined precisely in many situations. Considering the imprecise characteristics of components, few works have… read more here.
