What
are the ways to do reliability prediction? You can use various reliability prediction techniques, depending on your knowledge of the details of your design. An early estimate can be made by comparing your product with products of similar function or complexity, of known reliability; generally, this will be a crude estimate at best, as the many differences in design details between the products are not accounted for. As more details of your design are known, more accurate methods become available. These methods utilize part failure rate models, which predict the failure rates of parts based on various part parameters, such as technology, complexity, package type, quality level, and stress levels. Two of the better known failure rate prediction methods are Telcordia SR-332 and MIL-HDBK-217. These handbooks offer documented procedures for predicting product reliability, providing a standard basis for comparing reliability numbers. |
