Serial vs parallel processing. λ (lambda) = Failure rate = 1/MTBF. If both components are both working, then the system is working. Thecombined system is operational only if both Part X and Part Y are available.From this it follows that the combined availability is a product ofthe availability of the two parts. A method for combining data on individual component reliability to determine approximate confidence limits for the reliability of complete mechanisms is presented. In serial processing, same tasks are completed at the same time but in parallel processing completion time may vary. (2018).
