Mean time to repair
(MTTR) is the membership function of the fuzzy evaluation "excellent", "good", "general" and "poor", as shown in Figure 6:
Thus, for example, the relation of the mean time to repair
MTTR and of the reliability R to the component count F has a linear form (Figure 3 and 4).
Mean time between failure (MTBF) and mean time to repair
(MTTR) are assumed to follow Gamma distribution.
is the mean time to repair
. If the system consists of many items, the formula (9) can be generalized as follows:
As part of this analysis, evaluate the mean time between failure and the mean time to repair
for your critical equipment to determine if a failure modes and effects analysis is warranted.
ONPATH enables customers to increase their overall network security, reliability, and performance; increase the utilization and network uptime, of existing data center, monitoring, and security tools; monitor more with less budget and personnel; simplify the operation of their network; manage change more quickly; reduce mean time to repair
; and adhere to compliance mandates.
Conventional Mean Time to Repair
(MTTR) SLAs are based on an average of many incidents across devices; companies can experience an extended outage of one critical site or device that seriously impacts operations yet does not constitute an SLA violation.
"Nastel Technologies has used a Complex Event Processing (CEP) engine since 2001 as the core of its solution in order to help customers save money by reducing mean time to repair
(MTTR) and increasing mean time between failures (MTBF)," said Charley Rich, vice president of product management and marketing for Nastel.
where MTTF (Mean Time To Failure) is mean time till the failure occurs and MTTR (Mean Time To Repair
The system operating parameters are breakdown level (BL) and mean time to repair
(MTTR), while the system configuration parameters are number of job types to number of machine types (J/M) ratio, part complexity (PC) and part mix (PM).
MTTR (mean time to repair
) also has improved with the new software, Open Solutions said.
These switches allow corporations to minimize travel costs and Mean Time to Repair
, and to ensure the highest availability of data center services possible," said Kevin Chen, President of ATEN International.
