In the context of open source development or software evolution, developers often face test suites which have been developed with no apparent rationale and which may need to be augmented or refined to ensure sufficient dependability, or even reduced to meet tight deadlines.
However the conduct of a logistic regression analysis using a hierarchical data analysis model based on a theoretical framework helped us evaluate mediation of more proximal factors and their association with ECC [ 42], reduced the tendency for spurious associations and increased the dependability of the data analysis outcomes.
Finally, an important trade-off between Capital Expenditures (CAPEX) and dependability-related Operational Expenditures (OPEX) regarding PON physical layout is presented and solved, giving guidelines for designing PONs where the total cost is reduced.
This leads to a high level of dependability and safety, eases verification, reduces cost for safety licensing, and conforms particularly well with the safety standard IEC 61508.
intrusion-tolerant replication, with f>0, improves (mathcal{R}) for small MT, but for small ratios f/n it is prejudicial for large MT; rejuvenation cannot bring benefits before its first application, but it reduces the long-term degradation effects on dependability, by periodically bringing the system back to its initial overall state (i.e., with all nodes healthy see (20) in the Appendix).
It can improve both dependability and availability as well as significantly reduce the procurement, operation and maintenance costs of such systems.
This paper makes the case for increasing research emphasis on dependability and, specifically, on improving availability by reducing time-to-recover.
Good designs typically aim at reducing operational costs, e.g. through achieving high energy efficiency and improved dependability (i.e. reliability, availability and maintainability).
An early analysis of the relationship between dependability metrics, performability-area trade-off, and different mitigation techniques for such applications can reduce the design effort while increasing the design confidence.
The dependability analysis of safety-critical engineering systems during the early stages of design helps ensure that requirements are met and also reduces cost that may be incurred due to modifications later in the process.
Emphasize dependable behaviors, for "dependability" is a trait that includes timeliness, good quality and good service.
