The reliability engineering is the high utilization of system Product (i.e. Processor, Memory, File, Sh, K & Encryption key) Services, Business and Resources at minimal cost. The Real Time Operating System providing highest services at optimal cost and time. The reliability engineering provides the maximum performance, accountability, reliability, scalability, integrity and availability of processor, memory, file, Sh, Kernel and other inter dependency sub-components. The reliability engineering is the ratio of the maximum functionality of individual components to the minimal cost. RE = k ((P, M, F, K))/minimal cost. Where k is the proportionality constant. The RE is inversely proportional to the risk. The RE maximizes the throughput & decision process of business and system as well optimize the risk and down time. We have to develop the reliability engineering model & mechanism for risk optimization over a complex real time operating system for multiple business & technology. This proposed model integrate and mapping the SE, RE, SC with Product, Business & Resources in around the globe. Meanwhile Business, Engineering & Technology keep balance with product, services, operation & services as per CE. This semi-group model definitely resole our objective at high level of satisfaction. When reliability is increases with the fault tolerance increases and mean while the risk will be optimized as per business and resource requirement.
