Sensitivity Analysis and RAMD Investigation of Ghee Producing Unit of Milk Plant

Abstract

The main aim of present investigation is to perform sensitivity analysis and reliability, availability, maintainability, and
dependability (RAMD) investigation of ghee producing entity of milk plant. The ghee producing unit comprises four components viz.
melting vats, boilers, ghee clarifier and ghee settling tank. These components configured in series structure having various types of
redundancies. All the components’ failure and repair distribution are exponentially distributed. The switch devices, repairs are perfect
and sufficient repair facilities available with system. Simple probabilistic arguments and Markov methodology is used to derive the
reliability measures od system components. Various system effectiveness characteristics of ghee producing unit and its components
are derived. The numerical behavior of system in transient state is discussed to explore the execution of organization under various
failure and repair rates. It is revealed from numerical results that system availability is 0.75403 and ghee settling tank is most sensitive
component. The results may be utilized by maintenance personnel and system designers of milk plants to improve the performance of
the plants.
