What is ISOF-PROFAP
ISOF-PROFAP (Probabilistic Failure Prediction) is an environment, which allows advanced numerical estimation of failure probability for technical systems, in particular computer systems. This is achieved by individually run simulations, analysis and control over hardware operational reliability.
Integration with hardware registry
Reliability analysis is most usually performed on individual elements instead of on complex systems. With the use of ISOF-PROFAP one can model any structure of IT hardware. ISOF-PROFAP is integrated with a hardware registry module of the ISOF system. As a result the calculations are performed on actual elements of the company's fixed assets.
Protection of critical infrastructure
Implementation of ISOF-PROFAP can be particularly valuable in banking systems, where each failure is costly from both economical and marketing standpoint, because each time it is widely commented by the media. The system also helps to fulfill the requirements of new D and M Recommendations issued by the Komisja Nadzoru Finansowego (eng. Polish Financial Supervision Authority).
AFR Coefficient
The registry of each device can contain its numerical characteristic in the form of density probability distribution of failure expressed using the Annualized Failure Rate coefficient. Ergonomic interface allows to easily enter hundreds of individual elements into the system and the calculation of the coefficient for the entire system, a group of or individual devices. As a result it is possible to model a device structure, which includes both redundancy, as well as direct dependency of devices. This builds an efficient and mathematically credible mechanism of reliability estimation. The analysis results can be saved in DMS and a Results Dashboard (Management Cockpit) can be defined – a spreadsheet containing the results of reliability analysis for the entire device as well as all of its individual components.
