A model of reliability, average reliability, availability, maintainability and supportability for services with system dynamics approach

摘要

In this paper, we compute a dynamic of reliability, average reliability, availability, maintainability, and supportability (RARAMS) of enterprise services and their relationship to the demands. Therefore, we propose a dynamic simulation model that forms a closed system, contains negative feedback and time delay. The closed system is formed by the effect of the average reliability to demand. Next, negative feedback is due to the opposite relationship between service time of demand fulfillment and reliability of services. Based on these characteristics, we use system dynamics simulation approach to run the model so that the model results in the dynamic behavior of both RAMS of enterprise services and demands.
