J.D. Power car dependability: Lower rated brands see biggest gains.
This situation generally resulted in lower dependability (phi) coefficients for TTE global rating scores than for TTE total checklist scores in comparable test situations (Table 3).
Emphasize dependable behaviors, for "dependability" is a trait that includes timeliness, good quality and good service.
Though the number of problems has continued to fall across the industry, the rate of improvement in dependability has slowed somewhat, Mr. Sargent said.
In the listing of "How will the 2002s fare?"–meaning projected reliability many of the recommended cars are rated with below-average dependability, and that includes Detroit brands and foreign nameplates.
Their solution monitors web services and generates resilience metadata representing dependability attributes, such as response time, failure rate, failure types and so on (Yuhui and Romanovsky[2008]).
All but one of these measurements (dependability) showed significant improvement (p ≤ 0.05) as mentors rated themselves progressing from 12 weeks in the NE STEM 4U program to 24 weeks, n = 27.
The most quantitative ways to compute parameters of Dependability (Reliability, Availability, Maintainability, Safety) are asymptotic studies with constant rates.
Domestic brands improved at a slightly faster rate than import brands and narrowed the gap in dependability to 13 problems per 100 vehicles from 18 problems per 100 in last year's survey.
Therefore, it requires an assessment of dependability; this might be expressed, for example, as probability of failure upon demand, rate of occurrence of failures, probability of mission failure, and so on.
