A Comparative Study of Hybrid Systems Using RAMD Analysis
Keywords:
Availability, Analysis, Comparative, Dependability, Hybrid, Maintainability, ReliabilityAbstract
Hybrid systems, combining diverse technologies or methodologies, have emerged as promising solutions across various domains, from renewable energy to transportation and beyond. This study conducts a comprehensive analysis of hybrid systems employing the Reliability, Availability, Maintainability, and Dependability (RAMD) framework. In this study, two systems are established, each composed of subsystems A and B. In the first system, both A and B contain active units, with two units in A and four in B. In the second system, A has two active units, while B is split between two human operators: one overseeing two units, and the other managing four. The objective is to evaluate and compare their performance, considering their reliability, availability, maintainability, and dependability (RAMD) aspects. RAMD analysis plays a pivotal role in optimizing operational efficiency and productivity by identifying opportunities for improvement within systems.
