Reliability and Availability are considered to be type of equipments life parameters. Parallel look like other production systems are consists of many equipments, therefore, each of reliability and availability indicates that whether the system is effective or not. In other hand markov models were used to evaluates the functions whose state had been changed in its levels within time changing. Hence each of Reliability, Availability and Markov Models ( RAMM ) can be joined together and employed in evaluation of production systems.
Production managers needing to know the productivity of the system which involved in their production plan. This paper introduces an analysis of RAMM with parallel production system in order to estimates its productivity, where such techniques are used individually. It was concluded that Availability and Markov Models are suitable to be used in estimation of productivity, which was depended in production planning.
